Module GTK2
- Methodadd_builtin_icon
voidadd_builtin_icon(stringname,intsize,GTK2.GdkPixbufpixbuf)- Description
Registers a built-in icon for icon theme lookups. The idea of build-in icons is to allow an application or library that uses themed icons to function requiring files to be present in the file system. For instance, the default images for all of GTK2+'s stock icons are registered as built-in icons.
In general, if you use add_builtin_icon() you should also install the icon in the icon theme, so that the icon is generally available.

- Methodset_auto_startup_notification
voidset_auto_startup_notification(intsetting)- Description
By default, after showing the first GTK2.Window for each GDK2.Screen, GTK+ calls GDK2.Screen->notify_startup_complete(). Call this function to disable the automatic startup notification. You might do this if your first window is a splash screen, and you want to delay notification until after your real main window has been shown, for example.
In that example, you would disable startup notification temporarily, show your splash screen, then re-enable it so that showing the main window would automatically result in notification.

Class GTK2.ActionGroup
- Description
Actions are organized into groups. An action group is essentially a map from names to GTK2.Action objects.
All actions that would make sense to use in a particular context should be in a single group. Multiple action groups may be used for a particular user interface. In fact, it is expected that most non-trivial applications will make use of multiple groups. For example, in an application that can edit multiple documents, one group holding global actions (e.g. quit, about, new), and one group per document holding actions that act on that document (eg. save, cut/copy/paste, etc). Each window's menus would be constructed from a combination of two action groups.
Accelerators are handled by the GTK2+ accelerator map. All actions are assigned an accelerator path (which normally has the form <Actions>/group-name/action-name) and a shortcut is associated with this accelerator path. All menuitems and toolitems take on this accelerator path. The GTK2+ accelerator map code makes sure that the correct shortcut is displayed next to the menu item. Properties: string name int sensitive int visible

Class GTK2.Adjustment
- Description
The GTK2.Adjustment object represents a value which has an associated lower and upper bound, together with step and page increments, and a page size. It is used within several GTK2+ widgets, including GtkSpinButton, GtkViewport, and GtkRange (which is a base class for GtkHScrollbar, GtkVScrollbar, GtkHScale, and GtkVScale).
The GtkAdjustment object does not update the value itself. Instead it is left up to the owner of the GtkAdjustment to control the value.
The owner of the GtkAdjustment typically calls the value_changed() and changed() functions after changing the value or its bounds. This results in the emission of the "value_changed" or "changed" signal respectively.
Properties: float lower float page-increment float page-size float step-increment float upper float value
Signals: changed The adjustment changed in some way
value_changed The value changed
- Methodclamp_page
GTK2.Adjustmentclamp_page(floatlower,floatupper)- Description
Updates the W(Adjustment) value to ensure that the range between lower and upper is in the current page (i.e. between value and value+page_size). If the range is larger than the page size, then only the start of it will be in the current page. A "changed" signal will be emitted if the value is changed.
- Methodcreate
GTK2.AdjustmentGTK2.Adjustment(float|mappingvalue_or_props,float|voidlower,float|voidupper,float|voidstep_increment,float|voidpage_increment,float|voidpage_size)- Description
The value argument is the initial value you want to give to the adjustment, usually corresponding to the topmost or leftmost position of an adjustable widget. The lower argument specifies the lowest value which the adjustment can hold. The step_increment argument specifies the "smaller" of the two increments by which the user can change the value, while the page_increment is the "larger" one. The page_size argument usually corresponds somehow to the visible area of a panning widget. The upper argument is used to represent the bottom most or right most coordinate in a panning widget's child. Therefore it is not always the largest number that value can take, since the page_size of such widgets is usually non-zero.
All values are optional, they default to 0.0. For most widgets the unit is pixels.
- Methodset_value
GTK2.Adjustmentset_value(floatto)- Description
Sets the value. The value is clamped to lie between lower and upper.
Note that for adjustments which are used in a W(Scrollbar), the effective range of allowed values goes from lower to upper-page_size.
Class GTK2.Alignment
- Description
The W(Alignment) widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.
The scale settings are used to specify how much the child widget should expand to fill the space allocated to the W(Alignment). The values can range from 0 (meaning the child doesn't expand at all) to 1 (meaning the child expands to fill all of the available space).
The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.
NOIMG Properties: int bottom-padding int left-padding int right-padding int top-padding float xalign float xscale float yalign float yscale

A value of 0 indicates that the child widget should never expand. A value of 1 indicates that the child widget will expand to fill all of the space allocated for the GTK2.Alignment. yscale : the amount that the child widget expands vertically to fill up unused space, from 0 to 1. The values are similar to xscale.
- Methodset
GTK2.Alignmentset(floatxalign,floatyalign,floatxscale,floatyscale)- Description

GTK2.CellRendererTextset_fixed_height_from_font(intnumber_of_rows)- Description
Sets the height of a renderer to explicitly be determined by the "font" and "y_bad" property set on it. Further changes in these properties do not affect the height, so they must be accompanied by a subsequent call to this function. Using this function is unflexible, and should really only be used if calculating the size of cell is too slow (i.e., a massive number of cells displayed). If number_of_rows is -1, then the fixed height is unset, and the height is determined by the properties again.

Class GTK2.EventBox
- Description
Some gtk widgets don't have associated X windows, so they just draw on their parents. Because of this, they cannot receive events and if they are incorrectly sized, they don't clip so you can get messy overwritting etc. If you require more from these widgets, the EventBox is for you.
At first glance, the EventBox widget might appear to be totally useless. It draws nothing on the screen and responds to no events. However, it does serve a function - it provides an X window for its child widget. This is important as many GTK2 widgets do not have an associated X window. Not having an X window saves memory and improves performance, but also has some drawbacks. A widget without an X window cannot receive events, and does not perform any clipping on it's contents. Although the name EventBox emphasizes the event-handling function, the widget can also be used for clipping.
The primary use for this widget is when you want to receive events for a widget without a window. Examples of such widgets are labels and images.

The default is to keep the window below the child.

Class GTK2.FileChooserDialog
- Description
GtkFileChooserDialog should be used to retrieve file or directory names from the user. It will create a new dialog window containing a directory list, and a file list corresponding to the current working directory. The filesystem can be navigated using the directory list, the drop-down history menu, or the TAB key can be used to navigate using filename completion common in text based editors such as emacs and jed.
The default filename can be set using set_filename() and the selected filename retrieved using get_filename().
Use complete() to display files that match a given pattern. This can be used for example, to show only *.txt files, or only files beginning with gtk*.
Simple file operations; create directory, delete file, and rename file, are available from buttons at the top of the dialog. These can be hidden using hide_fileop_buttons() and shown again using show_fileop_buttons().

Class GTK2.Gnome2Appbar
- Description
A bar that GNOME applications put on the bottom of the windows to display status, progress, hints for menu items or a minibuffer for getting some sort of response. It has a stack for status messages
 GTK2.Gnome2Appbar( 1, 1, GTK2.GNOME_PREFERENCES_USER )->set_progress_percentage( 0.4 );
Properties: int has-progress int has-status int interactivity
Signals: clear_prompt Emitted when the prompt is cleared. mixed user_data
user_response Emitted when the user hits enter after a prompt. mixed user_data
- Methodclear_stack
Gnome2.Appbarclear_stack()- Description
Remove all status messages from appbar, and display default status message (if present).
- Methodcreate
GTK2.Gnome2AppbarGTK2.Gnome2Appbar(inthas_progress,inthas_status,intinteractivity)- Description
Create a new GNOME application status bar. If has_progress is TRUE, a small progress bar widget will be created, and placed on the left side of the appbar. If has_status is TRUE, a status bar, possibly an editable one, is created.
interactivity determines whether the appbar is an interactive "minibuffer" or just a status bar. If it is set to Gnome2.PREFERENCES_NEVER, it is never interactive. If it is set to Gnome2.PREFERENCES_USER we respect user preferences from ui-properties. If it's Gnome2.PREFERENCES_ALWAYS we are interactive whether the user likes it or not. Basically, if your app supports both interactive and not (for example, if you use the gnome-app-util interfaces), you should use Gnome2.PREFERENCES_USER. Otherwise, use the setting you support. Please note that "interactive" mode is not functional now; GtkEntry is inadequate and so a custom widget will be written eventually.

Class GTK2.Gnome2Canvas
- Description
Gnome2.Canvas is an engine for structured graphics that offers a rich imaging model, high performance rendering, and a powerful, high level API. It offers a choice of two rendering back-ends, one based on Xlib for extremely fast display, and another based on Libart, a sophisticated, antialiased, alpha-compositing engine. This widget can be used for flexible display of graphics and for creating interactive user interface elements.
A Gnome2.Canvas widget contains one or more Gnome2.CanvasItem objects. Items consist of graphing elements like lines, ellipses, polygons, images, text, and curves. These items are organized using Gnome2.CanvasGroup objects, which are themselves derived from Gnome2.CanvasItem. Since a group is an item it can be contained within other groups, forming a tree of canvas items. Certain operations, like translating and scaling, can be performed on all items in a group. See http://developer.gnome.org/doc/API/2.0/libgnomecanvas/GnomeCanvas.html for more information. Properties: int aa
Signals: draw_background

mappingget_scroll_region()- Description
Queries the scrolling region of a canvas.
- Methodscroll_to
Gnome2.Canvasscroll_to(intcx,intcy)- Description
Makes a canvas scroll to the specified offsets, given in canvas pixel units. The canvas will adjust the view so that it is not outside the scrolling region. This function is typically not used, as it is better to hook scrollbars to the canvas layout's scrolling adjustments.
- Methodset_center_scroll_region
Gnome2.Canvasset_center_scroll_region(intsetting)- Description
When the scrolling region of the canvas is smaller than the canvas window, e.g. the allocation of the canvas, it can be either centered on the window or simply made to be on the upper-left corner on the window.
- Methodset_dither
Gnome2.Canvasset_dither(intdither)- Description

- Methodset_pixels_per_unit
Gnome2.Canvasset_pixels_per_unit(floatn)- Description
Sets the zooming factor of a canvas by specifying the number of pixels that correspond to one canvas unit.
The anchor point for zooming, i.e. the point that stays fixed and all others zoom inwards or outwards from it, depends on whether the canvas is set to center the scrolling region or not. You can contorl this using the set_center_scroll_region() function. If the canvas is set to center the scroll region, then the center of the canvas window is used as the anchor point for zooming. Otherwise, the upper-left corner of the canvas window is used as the anchor point.
- Methodset_scroll_region
Gnome2.Canvasset_scroll_region(floatx1,floaty1,floatx2,floaty2)- Description

die Called when the session manager wants the client to shut down. mixed user_data
disconnect Called when the client is disconnected from the session manager. mixed user_data
save_complete Called when the session manager has finished checkpointing all of the clients. Clients are then free to change their state. mixed user_data
save_yourself Called when either a "SaveYourself" or a "SaveYourselfPhase2" call is made by the session manager. int arg1: the phase of the "SaveYourself" command ('1' or '2'). int arg2: the data which should be saved (local, global, or both). int arg3: true if the session manager is shutting down. int arg4: how the client is allowed to interact with the user while saving. int arg5: true if this is to be a "fast" shutdown. mixed user_data
shutdown_cancelled Called if the session manager had sent a "SaveYourself" to all clients in preparation for shutting down and the shutdown was then cancelled. A client can then continue running and change its state. mixed user_data
- Methodcreate
GTK2.Gnome2ClientGTK2.Gnome2Client()- Description
Gets the master session management client.
- Methodflush
Gnome2.Clientflush()- Description
This will force the underlying connection to the session manager to be flushed. This is useful if you have some pending changes that you want to make sure get committed.
- Methodget_config_prefix
stringget_config_prefix()- Description
Get the config prefix. This config prefix provides a suitable place to store any details about the state of the client which can not be described using the app's command line arguments (as set in the restart command).
- Methodget_desktop_id
stringget_desktop_id()- Description
Get the client ID of the desktop's current instance, i.e. if you consider the desktop as a whole as a session managed app, this returns its session ID using a gnome extension to session management. May return empty for apps not running under a recent version of gnome-session; apps should handle that case.
- Methodget_global_config_prefix
stringget_global_config_prefix()- Description
Get the config prefix that will be returned by get_config_prefix() for clients which have NOT been restarted or cloned (i.e. for clients started by the user without '--sm-' options). This config prefix may be used to write the user's preferred config for these "new"clients".
You could also use this prefix as a place to store and retrieve config details that you wish to apply to ALL instances of the app. However, this practice limits the users freedom to configure each instance in a different way so it should be used with caution.
- Methodget_previous_id
stringget_previous_id()- Description
Get the session management ID from the previous session.
- Methodrequest_phase_2
Gnome2.Clientrequest_phase_2()- Description
Request the session manager to emit the "save-yourself" signal for a second time after all the clients in the session have ceased interacting with the user and entered an idle state. This might be useful if your app managers other apps and requires that they are in an idle state before saving its final data.
- Methodrequest_save
Gnome2.Clientrequest_save(intsave_style,intshutdown,intinteract_style,intfast,intglobal)- Description
Request the session manager to save the session in some way. The arguments correspond with the arguments passed to the "save-yourself" signal handler.
The save_style (
GNOME_SAVE_BOTH,GNOME_SAVE_GLOBALandGNOME_SAVE_LOCAL) indicates whether the save should affect data accessible to other users (GTK2.GNOME_SAVE_GLOBAL) or only the state visible to the current user (GTK2.GNOME_SAVE_LOCAL), or both. Setting shutdown to true will initiate a logout. The interact_style (GNOME_INTERACT_ANY,GNOME_INTERACT_ERRORSandGNOME_INTERACT_NONE) specifies which kinds of interaction will be available. Setting fast to true will limit the save to setting the session manager properties plus any essential data. Setting the value of global to true will request that all the other apps in the session do a save as well. A global save is mandatory when doing a shutdown.
- Methodsave_any_dialog
Gnome2.Clientsave_any_dialog(GTK2.Dialogdialog)- Description
May be called during a "save-yourself" handler to request that a (modal) dialog is presented to the user. The session manager decides when the dialog is shown, but it will not be shown it unless the session manager is sending an interaction style of GTK2.GNOME_INTERACT_ANY. "Cancel" and "Log out" buttons will be added during a shutdown.
- Methodsave_error_dialog
Gnome2.Clientsave_error_dialog(GTK2.Dialogdialog)- Description
May be called during a "save-yourself" handler when an error has occurred during the save.
- Methodset_clone_command

Gnome2.Clientset_current_directory(stringdir)- Description
Set the directory to be in when running shutdown, discard, restart, etc. commands.
- Methodset_discard_command
Gnome2.Clientset_discard_command(arrayargv)- Description
Provides a command to run when a client is removed from the session. It might delete session-specific config files, for example. Executing the discard command on the local host should delete the information saved as part of the session save that was in progress when the discard command was set. For example: string prefix=client->get_config_prefix(); array argv=({ "rm","-r" }); argv+=({ Gnome2.Config->get_real_path(prefix) }); client->set_discard_command(argv); Not implemented yet.
- Methodset_environment
Gnome2.Clientset_environment(stringname,stringvalue)- Description
Set an environment variable to be placed in the client's environment prior to running restart, shutdown, discard, etc. commands.
- Methodset_global_config_prefix
Gnome2.Clientset_global_config_prefix(stringprefix)- Description
Set the value used for the global config prefix. The global config prefix defaults to a name based on the name of the executable. This function allows you to set it to a different value. It should be called BEFORE retrieving the config prefix for the first time. Later calls will be ignored.
- Methodset_priority
Gnome2.Clientset_priority(intpriority)- Description
The gnome-session manager restarts clients in order of their priorities in a similar way to the start up ordering in SysV. This function allows the app to suggest a position in this ordering. The value should be between 0 and 99. A default value of 50 is assigned to apps that do not provide a value. The user may assign a different priority.
- Methodset_resign_command
Gnome2.Clientset_resign_command(arrayargv)- Description
Some clients can be "undone", removing their effects and deleting any saved state. For example, xmodmap could register a resign command to undo the keymap changes it saved.
Used by clients that use the GTK2.GNOME_RESTART_ANYWAY restart style to undo their effects (these clients usually perform initialization functions and leave effects behind after they die). The resign command combines the effects of a shutdown command and a discard command. It is executed when the user decides that the client should cease to be restarted. Not implemented yet.
- Methodset_restart_command
Gnome2.Clientset_restart_command(arrayargv)- Description
When clients crash or the user logs out and back in, they are restarted. This command should perform the restart. Executing the restart command on the local host should reproduce the state of the client at the time of the session save as closely as possible. Saving config info under the get_config_prefix() is generally useful. Not implemented yet.
- Methodset_restart_style
Gnome2.Clientset_restart_style(intstyle)- Description
Tells the session manager how the client should be restarted in future sessions. One of
GNOME_RESTART_ANYWAY,GNOME_RESTART_IF_RUNNING,GNOME_RESTART_IMMEDIATELYandGNOME_RESTART_NEVER
- Methodset_shutdown_command
Gnome2.Clientset_shutdown_command(arrayargv)- Description
GTK2.GNOME_RESTART_ANYWAY clients can set this command to run when the user logs out but the client is no longer running.
Used by clients that use the GTK2.GNOME_RESTART_ANYWAY restart style to undo their effects (these clients usually perform initialization functions and leave effects behind after they die). The shutdown command simply undoes the effects of the client. It is executed during a normal logout. Not implemented yet.

Class GTK2.Gnome2Druid
- Description
The GNOME druid is a system for assisting the user with installing a service. It is roughly equivalent in functionality to the "Wizards" available in Windows.
There are two major parts of the druid, the Gnome2.Druid widget, and the set of W(Gnome2.DruidPage) widgets. The Gnome2.Druid widget is the main widget that interacts with the user. It has a Next, a Prev, and a Cancel button, and acts as a container for the pages. It is not a top-level window, so it needs to be put in a W(GTK2.Window) in almost all cases. The W(Gnome2.DruidPage) is a virtual widget, from which all of the actual content of the page inherits from. There are currently three of these available within gnome-libs.
GNOME druids are fairly simple to program with. You start by creating a GnomeDruid into which you put all of your pages. This widget will handle the presentation of the W(GnomeDruidPage) widgets.
You then create all appropriate W(GnomeDruidPage) widgets. There are three implementations of these, although there is no reason why more couldn't be written. They are the W(GnomeDruidPageStart), the W(GnomeDruidPageStandard), and the W(GnomeDruidPageFinish). The W(GnomeDruidPageStandard) acts as a W(Container), and is probably the most commonly used druid page. The other ones, as their names might suggest, are used at the endpoints of the druid. More information on the specific properties of these widgets can be found on their respective pages.
You will need to add the pages to the druid in order for them to appear. The druid itself keeps an internal list of all pages, and using the prepend_page(), append_page(), and insert_page() functions will place them into it.
Properties: int show-finish int show-help
Signals: cancel This signal is emitted when the "cancel" button has been pressed. Note that the current druid page has the option to trap the signal and use it, if need be, preventing this signal from being emitted.

Class GTK2.Hseparator
- Description
Simply creates a horizontal separator. No bells or whistles.
 GTK2.Hseparator()->set_size_request(300,3)
Class GTK2.IconFactory
- Description
Icon factory, for holding icon sets.
- Methodadd
GTK2.IconFactoryadd(stringstock_id,GTK2.IconSeticon_set)- Description
Adds the given icon_set to the icon factory, under the name of stock_id. stock_id should be namespaced for your application, e.g. "myapp-whatever-icon". Normally applications create a GTK2.IconFactory, then add it to the list of default factories with add_default(). Then they pass the stock_id to widgets such as GTK2.Image to display the icon. Themes can provide an icon with the same name (such as "myapp-whatever-icon") to override your application's default icons. If an icon already existed in this factory for stock_id, it is unreferenced and replaced with the new icon_set.
- Methodadd_default
GTK2.IconFactoryadd_default()- Description
Adds an icon factory to the list of icon factories search by GTK2.Style->lookup_icon_set(). This means that, for example, GTK2.Image->create("stock-id") will be able to find icons in factory. There will normally be an icon factory added for each library or application that comes with icons. The default icon factories can be overridden by themes.
- Methodcreate
GTK2.IconFactoryGTK2.IconFactory()- Description
Creates a new GTK2.IconFactory. An icon factory manages a collection of GTK2.IconSets; a GTK2.IconSet manages a set of variants of a particular icon (i.e. a GTK2.IconSet contains variants for different sizes and widget states). Icons in an icon factory are named by a stock ID, which is a simple string identifying the icon. Each GTK2.Style has a list of GTK2.IconFactorys derived from the current theme; those icon factories are consulted first when searching for an icon. If the theme doesn't set a particular icon, GTK2+ looks for the icon in a list of default icon factories, maintained by add_default() and remove_default(). Applications with icons should add a default icon factory with their icons, which will allow themes to override the icons for the application.
- Methodlookup
GTK2.IconSetlookup(stringstock_id)- Description
Looks up stock_id in the icon factory, returning an icon set if found, otherwise 0. For display to the user, you should use GTK2.Style->lookup_icon_set() on the GTK2.Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.
- Methodlookup_default
GTK2.IconSetlookup_default(stringstock_id)- Description
Looks for an icon in the list of default icon factories. For display to the user, you should use GTK2.Style->lookup_icon_set() on the GTK2.Style for the widget that will display the icon, instead of using this function directly, so that themes are taken into account.
Class GTK2.IconInfo
- Description
Contains information found when looking up an icon in an icon theme.
- Methodget_base_size
intget_base_size()- Description
Gets the base size for the icon. The base size is a size for the icon that was specified by the icon theme creator. This may be different than the actual size of image; an example of this is small emblem icons that can be attached to a larger icon. These icons will be given the same base size as the larger icons to which they are attached.
- Methodget_builtin_pixbuf
GTK2.GdkPixbufget_builtin_pixbuf()- Description
Gets the built-in image for this icon, if any. To allow GTK2+ to use built-in icon images, you must pass the GTK2.ICON_LOOKUP_USE_BUILTIN to GTK2.IconTheme->lookup_icon().
- Methodget_filename
stringget_filename()- Description
Gets the filename for the icon. If the GTK2.ICON_LOOKUP_USE_BUILTIN flag was passed to GTK2.IconTheme->lookup_icon(), there may be no filename if a builtin icon is returned; in this case, you should use get_builtin_pixbuf().
- Methodload_icon
GTK2.GdkPixbufload_icon()- Description
Renders an icon previously looked up in an icon theme using GTK2.IconTheme->lookup_icon(); the size will be based on the size passed to GTK2.IconTheme->lookup_icon(). Note that the resulting pixbuf may not be exactly this size; an icon theme may have icons that differe slightly from their nominal sizes, and in addition GTK2+ will avoid scaling icons that it considers sufficiently close to the requested size or for which the source image would have to be scaled up too far. (This maintains sharpness.)
Class GTK2.IconSet
- Description
Iconset. A single icon.
- Methodadd_source
GTK2.IconSetadd_source(GTK2.IconSourcesource)- Description
Icon sets have a list of GTK2.IconSource, which they use as base icons for rendering icons in different states and sizes. Icons are scaled, made to look insensitive, etc. in render_icon(), but GTK2.IconSet needs base images to work with. The base images and when to use them are described by a GTK2.IconSource.
This function copies source, so you can reuse the same source immediately without affecting the icon set.
An example of when you'd use this function: a web browser's "Back to Previous Page" icon might point in a different direciton in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon, and you might add a separate source for each one.
You should nearly always add a "default" icon source with all fields wildcarded, which will be used as a fallback if no more specific source matches. GTK2.IconSet always prefers more specific icon sources to more generic icon sources. The order in which you add the sources to the icon set does not matter.
- Methodcreate
GTK2.IconSetGTK2.IconSet(GTK2.GdkPixbufpixbuf)- Description
Create a new GTK2.IconSet. A GTK2.IconSet represents a single icon in various sizes and widget states. It can provide a GDK2.Pixbuf for a given size and state on request, and automatically caches some of the rendered GDK2.Pixbuf objects.
Normally you would use GTK2.Widget->render_icon() instead of using GTK2.IconSet directly. The one case where you'd use GTK2.IconSet is to create application-specific icon sets to place in a GTK2.IconFactory.
Class GTK2.IconSize
- Description
Iconsize.
- Methodregister
intregister(stringname,intwidth,intheight)- Description
Registers a new icon size, along the same lines as GTK2.ICON_SIZE_MENU, etc. Returns the integer value for the size.
Class GTK2.IconSource
- Description
Iconsource.
- Methodcreate
GTK2.IconSourceGTK2.IconSource()- Description
Creates a new GTK2.IconSource. A GTK2.IconSource contains a GDK2.Pixbuf (or image filename) that serves as the base image for one or more of the icons in a GTK2.IconSet, along with a specification for which icons in the icon set will be based on that pixbuf or image file. An icon set contains a set of icons that represent "the same" logical concept in different states, different global text directions, and different sizes.
So for example a web browser's "Back to Previous Page" icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode small/large icons). So a single icon set would contain all those variants of the icon. GTK2.IconSet contains a list of GTK2.IconSource from which it can derive specific icon variants in the set.
In the simplest case, GTK2.IconSet contains one source pixbuf from which it derives all variants. The convenience function GTK2.IconSet->create(pixbuf) handles this case; if you only have one source pixbuf, just use that function.
If you want to use a different base pixbuf for different icon variants, you create multiple icon sources, mark which variants they'll be used to create, and add them to the icon set with GTK2.IconSet->add_source().
By default, the icon source has all parameters wildcarded. That is, the icon source will be used as the base icon for any desired text direction, widget state, or icon size.
- Methodget_direction
intget_direction()- Description
Obtains the text direction this icon source applies to. The return value is only useful/meaningful if the text direction is not wildcarded.
- Methodget_direction_wildcarded
intget_direction_wildcarded()- Description
Gets the value set by set_direction_wildcarded().
- Methodget_pixbuf
GTK2.GdkPixbufget_pixbuf()- Description
Retrieves the source pixbuf, or 0. In addition, if a filename source is in use, this function in some cases will return the pixbuf loaded from the filename. This is, for example, true for the GTK2.IconSource passed to the GTK2.Style->render_icon() virtual function.
- Methodget_size
intget_size()- Description
Obtains the icon size this source applies to. The return value is only useful/meaningful if the icon size is not wildcarded.
- Methodget_size_wildcarded
intget_size_wildcarded()- Description
Gets the value set by set_size_wildcarded().
- Methodget_state
intget_state()- Description
Obtains the widget state this icon source applies to. The return value is only useful/meaningful if the widget state is not wildcarded.
- Methodget_state_wildcarded
intget_state_wildcarded()- Description
Gets the value set by set_state_wildcarded().
- Methodset_direction
GTK2.IconSourceset_direction(intdir)- Description
Sets the text direction this icon source is intended to be used with.
Setting the text direction on an icon source makes no difference if the text direction is wildcarded. Therefore, you should usually call set_direction_wildcarded() to un-wildcard it in addition to calling this function.
- Methodset_direction_wildcarded
GTK2.IconSourceset_direction_wildcarded(intsetting)- Description
If the text direction is wildcarded, this source can be used as the base image for an icon in any text direction. If the text direction is not wildcarded, then the text direction the icon source applies to should be set with set_direction(), and the icon source will only be used with that text direction.
GTK2.IconSet prefers non-wildcarded sources (exact matches) over wildcarded sources, and will use an exact match when possible.
- Methodset_filename
GTK2.IconSourceset_filename(stringfilename)- Description
Sets the name of an image file to use as a base image when creating icon variants for GTK2.IconSet. The filename must be absolute.
- Methodset_icon_name
GTK2.IconSourceset_icon_name(stringname)- Description
Sets the name of an icon to look up in the current icon theme to use as a base image.
- Methodset_pixbuf

- Methodset_size
GTK2.IconSourceset_size(intsize)- Description
Sets the icon size this icon source is intended to be with.
- Methodset_size_wildcarded
GTK2.IconSourceset_size_wildcarded(intsetting)- Description
If the icon size is wildcarded, this source can be used as the base image for an icon of any size. If the size is not wildcarded, then the size the source applies to should be set with set_size() and the icon source will only be used with that specific size.
- Methodset_state
GTK2.IconSourceset_state(intstate)- Description
Sets the widget state this icon source is intended to be used with.
- Methodset_state_wildcarded
GTK2.IconSourceset_state_wildcarded(intsetting)- Description
If the widget state is wildcarded, this source can be used as the base image for an icon in any state. If the widget state is not wildcarded, then the state the source applies to should be set with set_state() and the icon source will only be used with that specific state.

- Methodprepend_search_path
GTK2.IconThemeprepend_search_path(stringpath)- Description
Prepends a directory to the search path.
- Methodrescan_if_needed

- Methodset_custom_theme
GTK2.IconThemeset_custom_theme(stringtheme_name)- Description
Sets the name of the icon theme that the GTK2.IconTheme object uses overriding system configuration. This function cannot be called on the icon theme objects return from get_default().
- Methodset_search_path
GTK2.IconThemeset_search_path(arraypath)- Description
Sets the search path for the icon theme object. When looking for an icon theme, GTK2+ will search for a subdirectory of one or more of the directories in path with the same name as the icon theme. (Themes from multiple of the path elemets are combined to allow themes to be extended by adding icons in the user's home directory.)
In addition if an icon found isn't found either in the current icon theme or the default icon theme, and an image file with the right name is found directly in one of the elements of path, then that image will be used for the icon name. (This is a legacy feature, and new icons should be put into the default icon theme, which is called DEFAULT_THEME_NAME, rather than directly on the icon path.)
Class GTK2.IconView
- Description
GTK2.IconView provides an alternative view on a list model. It displays the model as a grid of icons with labels. Like GTK2.TreeView, it allows to select one or multiple items (depending on the selection mode).

- Methodpath_is_selected
intpath_is_selected(GTK2.TreePathpath)- Description
Returns true if the icon pointed to by path is currently selected. If icon does not point to a valid location, false is returned.
- Methodscroll_to_path
GTK2.IconViewscroll_to_path(GTK2.TreePathpath,intuse_align,floatrow_align,floatcol_align)- Description
Moves the alignments to the position specified by path. row_align determines where the row is placed, and col_align determines where column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.
If use_align is FALSE, then the alignment arguments are ignored, and the tree does the minimum amount of work to scroll the item onto the screen. This means that the item will be scrolled to the edge closest to its current position. If the item is currently visible on the screen, nothing is done.
This funciton only works if the model is set, and path is a valid row on the model. If the model changes before this icon view is realized, the centered path will be modified to reflect this change.

Sets the current keyboard focus to be at path, and selects it. This is usefull when you want to focus the user's attention on a particular item. If cell is not 0, then focus is given to the cell speicified by it. Additionally, if start_editing is TRUE, then editing should be started in the specified cell.
This function is often followed by grab_focus() in order to give keyboard focus to the widget.
- Methodset_item_width
GTK2.IconViewset_item_width(intitem_width)- Description
Sets the item-width property which specifies the width to use for each item. If it is set to -1, the icon view will automatically determine a suitable item size.
- Methodset_markup_column

Class GTK2.Paned
- Description
GTK2.Paned is the base class for widgets with two panes, arranged either horizontally (W(HPaned)) or vertically (W(VPaned)). Child widgets are added to the panes of the widget with pack1() and pack2(). The division beween the two children is set by default from the size requests of the children, but it can be adjusted by the user.
A paned widget draws a separator between the two child widgets and a small handle that the user can drag to adjust the division. It does not draw any relief around the children or around the separator. (The space in which the separator is called the gutter). Often, it is useful to put each child inside a W(Frame) with the shadow type set to GTK2.ShadowIn so that the gutter appears as a ridge.
Each child has two options that can be set, resize and shrink. If resize is true, then when the GTK2.Paned is resized, that child will expand or shrink along with the paned widget. If shrink is true, then when that child can be made smaller than it's requisition by the user. Setting shrink to 0 allows the application to set a minimum size. If resize is false for both children, then this is treated as if resize is true for both children.
The application can set the position of the slider as if it were set by the user, by calling set_position().

Class GTK2.Range
- Description
The category of range widgets includes the ubiquitous scrollbar widget and the less common "scale" widget. Though these two types of widgets are generally used for different purposes, they are quite similar in function and implementation. All range widgets share a set of common graphic elements, each of which has its own X window and receives events. They all contain a "trough" and a "slider" (what is sometimes called a "thumbwheel" in other GUI environments). Dragging the slider with the pointer moves it back and forth within the trough, while clicking in the trough advances the slider towards the location of the click, either completely, or by a designated amount, depending on which mouse button is used.
As mentioned in the W(Adjustment) page, all range widgets are associated with an adjustment object, from which they calculate the length of the slider and its position within the trough. When the user manipulates the slider, the range widget will change the value of the adjustment.
All of the GTK range widgets react to mouse clicks in more or less the same way. Clicking button-1 in the trough will cause its adjustment's page_increment to be added or subtracted from its value, and the slider to be moved accordingly. Clicking mouse button-2 in the trough will jump the slider to the point at which the button was clicked. Clicking any button on a scrollbar's arrows will cause its adjustment's value to change step_increment at a time.
It may take a little while to get used to, but by default, scrollbars as well as scale widgets can take the keyboard focus in GTK. If you think your users will find this too confusing, you can always disable this by unsetting the GTK2.CanFocus flag on the scrollbar, like this:
scrollbar->unset_flag(GTK2.CanFocus);
The key bindings (which are, of course, only active when the widget has focus) are slightly different between horizontal and vertical range widgets, for obvious reasons. They are also not quite the same for scale widgets as they are for scrollbars, for somewhat less obvious reasons (possibly to avoid confusion between the keys for horizontal and vertical scrollbars in scrolled windows, where both operate on the same area).

- GTK2.UpdatePolicyContinuous
This is the default. The "value_changed" signal is emitted continuously, i.e., whenever the slider is moved by even the tiniest amount.
- GTK2.UpdatePolicyDiscontinuous
The "value_changed" signal is only emitted once the slider has stopped moving and the user has released the mouse button.
- GTK2.UpdatePolicyDelayed

Class GTK2.SizeGroup
- Description
Provides a mechanism for grouping a number of widgets together so they all request the same amount of space. This is typically usefull when you want a column of widgets to have the same size, but you can't use a W(Table) widget.
In detail, the size requiest for each widget in a GTK2.SizeGroup is the maximum of the sizes that would have been requested for each widget in the size group if they were not in the size group. The mode of the size group (see set_mode() determines whether this applies to the horizontal size, the vertical size, or both sizes.
Note that size groups only affect the amount of space requested, not the size that the widgets finally receive. If you want the widgets in a GTK2.SizeGroup to actually be the same size, you need to pack them in such a way that they get the size they request and not more. For example, if you are packing your widgets into a table, you would not include the GTK2.FILL flag.
GTK2.SizeGroup objects are referenced by each widget in the size group, so one you have added all widgets to a GTK2.SizeGroup, you can drop the initial reference to the size group. If the widgets in the size group are subsequently destroyed, then they will be removed from the size group; when all widgets have been removed, the size group will be freed.
Widgets can be part of multiple size groups; GTK+ will compute the horizontal size of a widget from the horizontal requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK2.SIZE_GROUP_HORIZONTAL or GTK2.SIZE_GROUP_BOTH, and the vertical size from the vertical requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK2.SIZE_GROUP_VERTICAL or GTK2.SIZE_GROUP_BOTH. Properties: int mode The directions in which the size group effects the requested sizes of its componenent widgets.
- Methodadd_widget
GTK2.SizeGroupadd_widget(GTK2.Widgetwidget)- Description
Adds a widget to the group. In the future, the requisition of the widget will be determined as the maximum of its requisition and the requisition of the other widgets in the size group. Whether this applies horizontally, vertically, or in both directions depends on the mode.
- Methodget_ignore_hidden
intget_ignore_hidden()- Description
Returns if invisible widgets are ignored when calculating the size.
- Methodget_widgets
arrayget_widgets()- Description
Returns the list of widgets associated with this size group.
- Methodset_ignore_hidden

- Methodset_mode
GTK2.SizeGroupset_mode(intmode)- Description
Sets the mode of the size group. One of
SIZE_GROUP_BOTH,SIZE_GROUP_HORIZONTAL,SIZE_GROUP_NONEandSIZE_GROUP_VERTICAL. The mode of the size group determines whether the widgets in the size group should all have the same horizontal requisition, all have the same vertical requisition, or should all have the same requisition in both directions.
Class GTK2.Socket
- Description
Together with W(Plug), GTK2.Socket provides the ability to embed widgets from one process into another process in a fashion that is transparent to the user. One process creates a GTK2.Socket widget and, passes the XID of that widget's window to the other process, which then creates a W(Plug) window with that XID. Any widgets contained in the W(Plug) then will appear inside the first applications window.
Note that if you pass the XID of the socket to another process that will create a plug in the socket, you must make sure that the socket widget is not destroyed until that plug is created. Violating this rule will cause unpredictable consequences, the most likely consequence being that the plug will appear as a separate toplevel window.
A socket can also be used to swallow arbitrary pre-existing top-level windows using steal(), though the integration when this is done will not be as close as between a W(Plug) and a GTK2.Socket.
Signals: plug_added

GTK2.SourceBufferset_max_undo_levels(intsetting)- Description
Sets the number of undo levels for user actions the buffer will track. If the number of user actions exceeds the limit set by this funcction, older actions will be discarded.
A new action is started whenever the function begin_user_action() is called. In general, this happens whenever the user presses any key which modifies the buffer, but the undo manager will try to merge similar consecutive actions, such as multiple character insertions into one action. But, inserting a newline does start a new action.
- Methodundo
GTK2.SourceBufferundo()- Description
Undoes the last user action which modified the buffer. Use can_undo() to check whether a call to this function will have any effect.
Actions are defined as groups of operations between a call to GTK2.TextBuffer->begin_user_action() and GTK2.TextBuffer->end_user_action(), or sequences of similar edits (inserts or deletes) on the same line.

- Methodprint_range_async
GTK2.SourcePrintJobprint_range_async(GTK2.TextIterstart,GTK2.TextIterend)- Description
Starts to print job asynchronously. This function will ready the job for printing and install an idle handler that will render one page at a time.
This function will not return immediately, as only page rendering is done asynchronously. Text retrieval and paginating happens within this function. Also, if highlighting is enabled, the whole buffer needs to be highlighted first.
To get notification when the job has finished, you must connect to the "finished" signal.
- Methodset_buffer

Sets the width (equivalent spaces) of tabulations for the printed text. The width in printing units will be calculated as the width of a string containing tabs_width spaces of the default font. Tabulation stops are set for the full width of printed text.
- Methodset_text_margins
GTK2.SourcePrintJobset_text_margins(floattop,floatbottom,floatleft,floatright)- Description
Sets the four user margins for the print job. These margins are in addition to the document margins provided in the GnomePrintConfig and will not be used for headers, footers, or line numbers (those are calculated separately). You can print in the space allocate by these margins by connecting to the "begin-page" signal. The space is around the printed text, and inside the margins specified in the GnomePrintConfig.
The margin numbers are given in device units. If any of the given values is less than 0, that particular margin is not altered by this function.

Class GTK2.SpinButton
- Description
The Spin Button widget is generally used to allow the user to select a value from a range of numeric values. It consists of a text entry box with up and down arrow buttons attached to the side. Selecting one of the buttons causes the value to "spin" up and down the range of possible values. The entry box may also be edited directly to enter a specific value.
The Spin Button allows the value to have zero or a number of decimal places and to be incremented/decremented in configurable steps. The action of holding down one of the buttons optionally results in an acceleration of change in the value according to how long it is depressed.
The Spin Button uses an W(Adjustment) object to hold information about the range of values that the spin button can take.
The attributes of an W(Adjustment) are used by the Spin Button in the following way: <ul><li>value: initial value for the Spin Button</li> <li>lower: lower range value</li> <li>upper: upper range value</li> <li>step_increment: value to increment/decrement when pressing mouse button 1 on a button</li> <li>page_increment: value to increment/decrement when pressing mouse button 2 on a button</li> <li>page_size: unused</li> </ul>
The argument order for the W(Adjustment) constructor is: value, lower, upper, step_increment, page_increment, page_size

- Description
The "system tray" or notification area is normally used for transient icons that indicate some special state. For example, a system tray icon might appear to tell the user that they have new mail, or have an incoming instant message, or something along those lines. The basic idea is that creating an icon in the notification area is less annoying than popping up a dialog.
A GTK2.StatusIcon object can be used to display an icon in a "system tray". The icon can have a tooltip, and the user can interact with it by activating it or popping up a context menu. Critical information should/ not solely be displayed in a GTK2.StatusIcon, since it may not be visible (e.g. when the user doesn't have a notification area on his panel). This can be checked with is_embedded().
On X11, the implementation follows the freedesktop.org "System Tray" specification. Implementations of the "tray" side of this specification can be found e.g. in the GNOME and KDE panel applications.
Note that a GTK2.StatusIcon is not a widget, but just a G.Object. Making it a widget would be impractical, since the system tray on Win32 doesn't allow to embed arbitrary widgets.

Class GTK2.Statusbar
- Description
Statusbars are simple widgets used to display a text message. They keep a stack of the messages pushed onto them, so that popping the current message will re-display the previous text message.
In order to allow different parts of an application to use the same statusbar to display messages, the statusbar widget issues Context Identifiers which are used to identify different 'users'. The message on top of the stack is the one displayed, no matter what context it is in. Messages are stacked in last-in-first-out order, not context identifier order.

Properties: int column-spacing int homogeneous int n-columns int n-rows int row-spacing
Child properties: int bottom-attach int left-attach int right-attach int top-attach int x-options int x-padding int y-options int y-padding
- Methodattach
GTK2.Tableattach(GTK2.Widgetsubwidget,intleft,intright,inttop,intbottom,intxoptions,intyoptions,intxpad,intypad)- Description
The left and right attach arguments specify where to place the widget, and how many boxes to use. If you want a button in the lower right table entry of our 2x2 table, and want it to fill that entry ONLY. left_attach would be = 1, right_attach = 2, top_attach = 1, bottom_attach = 2.
Now, if you wanted a widget to take up the whole top row of our 2x2 table, you'd use left_attach = 0, right_attach = 2, top_attach = 0, bottom_attach = 1.
The xoptions and yoptions are used to specify packing options and may be OR'ed together to allow multiple options.
These options are: <ul> <li> GTK2.Fill - If the table box is larger than the widget, and GTK_FILL is specified, the widget will expand to use all the room available.</li> <li> GTK2.Shrink - If the table widget was allocated less space then was requested (usually by the user resizing the window), then the widgets would normally just be pushed off the bottom of the window and disappear. If GTK_SHRINK is specified, the widgets will shrink with the table.</li> <li> GTK2.Expand - This will cause the table cell to expand to use up any remaining space in the window.</li> </ul>
Padding is just like in boxes, creating a clear area around the widget specified in pixels
- Methodattach_defaults
GTK2.Tableattach_defaults(GTK2.Widgetsubwidget,intleft,intright,inttop,intbottom)- Description
As there are many options associated with attach(), this convenience function provides the programmer with a means to add children to a table with identical padding and expansion options.
xoptions, yoptions, xpadding and ypadding are all set the their default values. For the options that is GTK2.Fill|GTK2.Expand. For the padding it is 0.
- Methodcreate
GTK2.TableGTK2.Table(int|mappingwidth_or_props,int|voidheight,int|voidhomogeneousp)- Description
Used to create a new table widget. An initial size must be given by specifying how many rows and columns the table should have, although this can be changed later with resize().
There can never be more than 65535 colums nor more than 65535 rows.
setting homogeneousp to 1 forces the all tablecells to be exactly the same size.
- Methodget_col_spacing
intget_col_spacing(intcol)- Description
Gets the amound of space between col and col+1.
- Methodget_default_col_spacing
intget_default_col_spacing()- Description
Gets the default column spacing for the table.
- Methodget_default_row_spacing
intget_default_row_spacing()- Description
Gets the default row spacing for the table.
- Methodget_homogeneous
intget_homogeneous()- Description
Returns whether the table cells are all constrained to the same width and height.
- Methodget_row_spacing
intget_row_spacing(introw)- Description
Gets the amount of space between row and row+1.
- Methodresize
GTK2.Tableresize(introws,intcolumns)- Description
If you need to change a table's size after it has been created, this function allows you to do so.
- Methodset_col_spacing
GTK2.Tableset_col_spacing(intx,intspacing)- Description
alters the amount of space between a given table column and the adjacent columns.
- Methodset_col_spacings
GTK2.Tableset_col_spacings(intspacing)- Description
Sets the space between every column in the table equal to spacing.
- Methodset_row_spacing
GTK2.Tableset_row_spacing(inty,intspacing)- Description
alters the amount of space between a given table row and the adjacent rows.
Class GTK2.TearoffMenuItem
- Description
A GTK2.TearoffMenuItem is a special W(MenuItem) which is used to tear off and reattach its menu.
When its menu is shown normally, the GTK2.TearoffMenuItem is drawn as a dotted line indicating that the menu can be torn off. Activating it causes its menu to be torn off and displayed in its own window as a tearoff menu.
When its menu is shown as a tearoff menu, the GTK2.TearoffMenuItem is drawn as a dotted line which has a left pointing arrow graphic indicating that the tearoff menu can be reattached. Activating it will erase the tearoff menu window.
 GTK2.TearoffMenuItem()->set_size_request(100,0)
Class GTK2.TextAttributes
- Description
Holds text attributes.
- Methodcopy_values
GTK2.TextAttributescopy_values(GTK2.TextAttributesdest)- Description
Copies src onto dest

- Methodadd_selection_clipboard
GTK2.TextBufferadd_selection_clipboard(GTK2.Clipboardclipboard)- Description
Adds clipboard to the list of clipboards in which the selection contents of the buffer are available. In most cases, clipboard will be the GTK2.Clipboard of GDK2.SELECTION_PRIMARY for a view of this buffer.
- Methodapply_tag
GTK2.TextBufferapply_tag(GTK2.TextTagtag,GTK2.TextIterstart,GTK2.TextIterend)- Description
Emits the "apply-tag" signal. The default handler for the signal applies tag to the given range, start and end do not have to be in order.
- Methodapply_tag_by_name
GTK2.TextBufferapply_tag_by_name(stringname,GTK2.TextIterstart,GTK2.TextIterend)- Description
Calls GTK2.TextTagTable->lookup() on the buffers tag table to get a GTK2.TextTag, then calls apply_tag().
- Methodbackspace
intbackspace(GTK2.TextIteriter,intinteractive,intdefault_editable)- Description
Performs the appropriate action as if the user hit the delete key with the cursor at the position specified by iter. In the normal case a single character will be deleted, but when combining accents are involved, more than one character can be deleted, and when precomposed character and accent combinations are involved, less than one character will be deleted.
Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, iter will be re-initialized to point to the location where text was deleted.
- Methodbegin_user_action
GTK2.TextBufferbegin_user_action()- Description
Called to indicate that the buffer operations between here and call end_user_action() are part of a single user-visible operation. The operations between begin_user_action() and end_user_action() can then be grouped when creating an undo stack. W(TextBuffer) maintains a count of calls to begin_user_action() that have not been closed with a call to end_user_action(), and emits the "begin-user-action" and "end-user-action" signals only for the outermost pair of calls. This allows you to build user actions from other user actions.
The "interactive" buffer mutation functions, such as insert_interactive(), automatically call begin/end user action around the buffer operations they perform, so there's no need to add extra calls if your user action consists solely of a single call to one of those functions.
- Methodcopy_clipboard
GTK2.TextBuffercopy_clipboard(GTK2.Clipboardclipboard)- Description
Copies the currently-selected text to a clipboard.
- Methodcreate
GTK2.TextBufferGTK2.TextBuffer(GTK2.TextTagTabletable_or_props)- Description
Creates a new text buffer.
- Methodcreate_child_anchor
GTK2.TextChildAnchorcreate_child_anchor(GTK2.TextIteriter)- Description
This is a convenience function which simply creates a child anchor with GTK2.TextChildAnchor->create() and inserts it into the buffer with insert_child_anchor(). The new anchor is owned by the buffer; no reference count is returned.
- Methodcreate_mark
GTK2.TextMarkcreate_mark(GTK2.TextIterwhere,intleft_gravity,string|voidmark_name)- Description
Creates a mark at position where. If mark_name is omitted, the mark is anonymous; otherwise, the mark can be retrieve by name using get_mark(). If a mark has left gravity, and text is inserted at the mark's current location, the mark will be moved to the left of the newly-inserted text. If the mark has right gravity, the mark will end up on the right of the newly-inserted text. The standard left-to-right cursor is a mark with right gravity (when you type, the cursor stays on the right side of the text you're typing). Emits the "mark-set" signal as notification of the mark's initial placement.
- Methodcreate_tag
GTK2.TextTagcreate_tag(stringtag_name,mappingprops)- Description
Creates a tag and adds it to the tag table. Equivalent to calling GTK2.TextTag->create() and then adding the tag to the tag table. The returned tag is owned by the tag table.
- Methodcut_clipboard
GTK2.TextBuffercut_clipboard(GTK2.Clipboardclipboard,intdefault_editable)- Description
Copies the currently-selected text to a clipboard, then deletes said text if it's editable.
- Methoddelete
GTK2.TextBufferdelete(GTK2.TextIterstart,GTK2.TextIterend)- Description
Deletes text between start and end. The order of start and end is not actually relevant; delete() will reorder them. This function actually emits the "delete-range" signal, and the default handler of that signal deletes the text. Because the buffer is modified, all outstanding iterators become invalid after calling this function; however, start and end will be re-initialized to point to the location where text was deleted.
- Methoddelete_interactive
intdelete_interactive(GTK2.TextIterstart,GTK2.TextIterend,intdefault_editable)- Description
Deletes all editable text in the given range. Calls delete() for each editable sub-range of [start,end). start and end are revalidated to point to the location of the last deleted range, or left untouched if no text was deleted.
- Methoddelete_mark
GTK2.TextBufferdelete_mark(GTK2.TextMarkmark)- Description
Deletes mark, so that it's no longer located anywhere in the buffer. Removes the reference the buffer holds to the mark. There is no way to undelete a mark. The "mark-deleted" signal will be emitted as notification after the mark is deleted.
- Methoddelete_mark_by_name
GTK2.TextBufferdelete_mark_by_name(stringname)- Description
Deletes the mark named name; the mark must exist.
- Methoddelete_selection
intdelete_selection(intinteractive,intdefault_editable)- Description
Deletes the range between the "insert" and "selection_bound" marks, that is, the currently-selected text. If interactive is true, the editability of the selection will be considered (users can't delete uneditable text).
- Methodend_user_action
GTK2.TextBufferend_user_action()- Description
Should be paired with begin_user_action();
- Methodget_bounds
arrayget_bounds()- Description
Retrieves the first and last iterators in the buffer, i.e. the entire buffer lies within the range [start,end).
- Methodget_char_count
intget_char_count()- Description
Gets the number of characters in the buffer; note that characters and bytes are not the same, you can't e.g. expect the contents of the buffer in string form to be this many bytes long.
- Methodget_end_iter
GTK2.TextIterget_end_iter()- Description
Returns the "end iterator", one past the last valid character in the buffer. If dereferenced with W(TextIter)->get_char(), the end iterator has a character value of 0. The entire buffer lies in the range from the first position in the buffer to the end iterator.
- Methodget_has_selection
intget_has_selection()- Description
Indicates whether some text is currently selected.
- Methodget_insert
GTK2.TextMarkget_insert()- Description
Returns the mark that represents the cursor (insertion point). Equivalent to calling get_mark() to get the mark named "insert", but very slightly more efficient, and involves less typing.
- Methodget_iter_at_child_anchor
GTK2.TextIterget_iter_at_child_anchor(GTK2.TextChildAnchoranchor)- Description
Returns the location of anchor.
- Methodget_iter_at_line
GTK2.TextIterget_iter_at_line(intline)- Description
Returns a W(TextIter) to the start of the given line.
- Methodget_iter_at_line_index
GTK2.TextIterget_iter_at_line_index(intline,intbyte_index)- Description
Obtains an iterator point to byte_index with the given line. byte_index must be the start of a UTF-8 character, and must not be beyond the end of the line. Note bytes, not characters; UTF-8 may encode one character as multiple bytes.
- Methodget_iter_at_line_offset
GTK2.TextIterget_iter_at_line_offset(intline_number,intchar_offset)- Description
Obtains an iterator pointing to char_offset within the given line. The char_offset must exist, offsets off the end of the line are not allowed. Note characters, not bytes; UTF-8 may encode one character as multiple bytes.
- Methodget_iter_at_mark
GTK2.TextIterget_iter_at_mark(GTK2.TextMarkmark)- Description
Returns an iterator with the current position of mark.
- Methodget_iter_at_offset
GTK2.TextIterget_iter_at_offset(intoffset)- Description
Returns an iterator at position offset chars from the start of the entire buffer. If offset is -1 or greater than the number of characters in the buffer, returns the end iterator, the iterator one past the last valid character in the buffer.
- Methodget_modified
intget_modified()- Description
Indicates whether the buffer has been modified since the last call to set_modified() set the modification flag to false. Used for example to enable a "save" function in a text editor.
- Methodget_selection_bound
GTK2.TextMarkget_selection_bound()- Description
Returns the mark that represents the selection bound. Equivalent to calling get_mark() to get the mark named "selection_bound", but very slightly more efficient, and involves less typing.
The currently-selected text in the buffer is the region between the "selection_bound" and "insert" marks. If "selection_bound" and "insert" are in the same place, then there is no current selection. get_selection_bounds() is another convenient function for handling the selection, if you just want to know whether there's a selection and what its bounds are.
- Methodget_selection_bounds
arrayget_selection_bounds()- Description
Returns either an array with start and end W(TextIter) if some text is selected, or 0 if there's no active selection.
- Methodget_slice
stringget_slice(GTK2.TextIterstart,GTK2.TextIterend,intinclude_hidden_chars)- Description
Returns the text in the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is false. The returned string includes a 0xFFFC character whenever the buffer contains embedded images, so byte and character indexes into the returned string do correspond to byte and character indexes into the buffer. Contrast with get_text(). Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer.
- Methodget_start_iter
GTK2.TextIterget_start_iter()- Description
Returns an iterator with the first position in the text buffer. This is the same as using get_iter_at_offset() to get the iter at character offset 0.
- Methodget_tag_table
GTK2.TextTagTableget_tag_table()- Description
Get the W(TextTagTable) associated with this buffer.
- Methodget_text
stringget_text(GTK2.TextIterstart,GTK2.TextIterend,intinclude_hidden_chars)- Description
Returns the text int the range [start,end). Excludes undisplayed text (text marked with tags that set the invisibility attribute) if include_hidden_chars is false. Does not include characters representing embedded images, so byte and character indexes into the returned string do not correspond to byte and character indexes into the buffer. Contrast with get_slice().
- Methodinsert
GTK2.TextBufferinsert(GTK2.TextIteriter,stringtext,intlen)- Description
Insert len bytes of text at position iter. If len is -1, string will be inserted in its entirely. Emits the 'insert-text' signal. iter is invalidated after insertion, but the default signal handler revalidates it to point to the end of the inserted text.
- Methodinsert_at_cursor
GTK2.TextBufferinsert_at_cursor(stringtext,intlen)- Description
Simply calls insert(), using the current cursor position as the insertion point.
- Methodinsert_child_anchor
GTK2.TextBufferinsert_child_anchor(GTK2.TextIteriter,GTK2.TextChildAnchoranchor)- Description
Inserts a child widget anchor into the buffer at iter. The anchor will be counted as one character in character counts, and when obtaining the buffer contents as a string, will be represented by the Unicode "object replacement character" oxFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for child anchors, but the "text" variants do not. e.g. see get_slice() and get_text(). Consider create_child_anchor() as a more convenient alternative to this function. The buffer will add a reference to the anchor, so you can unref it after insertion.
- Methodinsert_interactive
intinsert_interactive(GTK2.TextIteriter,stringtext,intlen,intdefault_editable)- Description
Like insert(), but the insertion will not occur if iter is at a non- editable location in the buffer. Usually you want to prevent insertions at ineditable locations if the insertion results from a user action (is interactive).
default_edtibale indicates the editability of text that doesn't have a tag affecting editability applied to it. Typically the result of get_editable() is appropriate here.
- Methodinsert_interactive_at_cursor
intinsert_interactive_at_cursor(stringtext,intlen,intdefault_editable)- Description
Calls insert_interactive() at the cursor position.
- Methodinsert_pixbuf
GTK2.TextBufferinsert_pixbuf(GTK2.TextIteriter,GTK2.GdkPixbufpixbuf)- Description
Inserts an image into the text buffer at iter. The image will be counted as one character in character counts, and when obtaining the contents as a string, will be represented by the Unicode "object replacement character" 0xFFFC. Note that the "slice" variants for obtaining portions of the buffer as a string include this character for pixbufs, but the "text" variants do not. e.g. see get_slice() and get_text().
- Methodinsert_range
GTK2.TextBufferinsert_range(GTK2.TextIteriter,GTK2.TextIterstart,GTK2.TextIterend)- Description
Copies text, tags, and pixbufs between start and end (the order of start and end doesn't matter) and inserts the copy at iter. Used instead of simply getting/inserting text because it preserves images and tags. If start and end are in a different buffer from this buffer, the two buffers must share the same tag table.
Implemented via emissions of the insert-text and apply-tag signals, so expect those.
- Methodinsert_range_interactive
intinsert_range_interactive(GTK2.TextIteriter,GTK2.TextIterstart,GTK2.TextIterend,intdefault_editable)- Description
Same as insert_range(), but does nothing if the insertion point isn't editable. The default_editable parameter indicates whether the text is editable at iter if no tags enclosing iter affect editability.
- Methodinsert_with_tags
GTK2.TextBufferinsert_with_tags(GTK2.TextIteriter,stringtext,intlen,arraytags)- Description
Inserts text into the buffer at iter, applying the list of tags to the newly-inserted text. Equivalent to calling insert(), then apply_tag() on the insert text; insert_with_tags() is just a convenience function.
- Methodinsert_with_tags_by_name
GTK2.TextBufferinsert_with_tags_by_name(GTK2.TextIteriter,stringtext,intlen,arraytag_names)- Description
Same as insert_with_tags(), but allows you to pass in tag names instead of tag objects.
- Methodmove_mark
GTK2.TextBuffermove_mark(GTK2.TextMarkmark,GTK2.TextIterwhere)- Description
Moves mark to the new location where. Emits the "mark-set" signal as notification of the move.
- Methodmove_mark_by_name
GTK2.TextBuffermove_mark_by_name(stringname,GTK2.TextIterwhere)- Description
Moves the mark named name (which must exist) to location where.
- Methodpaste_clipboard
GTK2.TextBufferpaste_clipboard(GTK2.Clipboardclipboard,int|voiddefault_editable,GTK2.TextIterlocation)- Description
Pastes the contents of a clipboard at the insertion point, or at override_location.
- Methodplace_cursor
GTK2.TextBufferplace_cursor(GTK2.TextIterwhere)- Description
This function moves the "insert" and "selection_bound" marks simultaneously. If you move them to the same place in two steps with move_mark(), you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized.
- Methodremove_all_tags
GTK2.TextBufferremove_all_tags(GTK2.TextIterstart,GTK2.TextIterend)- Description
Removes all tags in the range between start and end. Be careful with this function; it could remove tags added in code unrelated to the code you're currently writing. That is, using this function is probably a bad idea if you have two or more unrelated code sections that add tags.
- Methodremove_selection_clipboard
GTK2.TextBufferremove_selection_clipboard(GTK2.Clipboardclipboard)- Description
Removes a clipboard that was added with add_selection_clipboard().
- Methodremove_tag
GTK2.TextBufferremove_tag(GTK2.TextTagtag,GTK2.TextIterstart,GTK2.TextIterend)- Description
Emits the "remove-tag" signal. The default handler for the signal removes all occurrences of tag from the given range. start and end do not have to be in order.
- Methodremove_tag_by_name
GTK2.TextBufferremove_tag_by_name(stringname,GTK2.TextIterstart,GTK2.TextIterend)- Description
Removes a tag. See apply_tag_by_name().
- Methodselect_range
GTK2.TextBufferselect_range(GTK2.TextIterins,GTK2.TextIterbound)- Description
This function removes the "insert" and "selection_bound" marks simultaneously. If you move them in two steps with move_mark(), you will temporarily select a region in between their old and new locations, which can be pretty inefficient since the temporarily-selected region will force stuff to be recalculated. This function moves them as a unit, which can be optimized.
- Methodset_modified
GTK2.TextBufferset_modified(intsetting)- Description
Used to keep track of whether the buffer has been modified since the last time it was saved. Whenever the buffer is saved to disk, call set_modified(0). When the buffer is modified, it will automatically toggle on the modified bit again. When the modifed bit flips, the buffer emits a "modified-changed" signal.
Class GTK2.TextChildAnchor
- Description
Anchors for embedding widgets in a TextBuffer.
- Methodcreate
GTK2.TextChildAnchorGTK2.TextChildAnchor()- Description
Creates a new W(TextChildAnchor). Usually you would then insert it into W(TextBuffer) with W(TextBuffer)->insert_child_anchor(). To perform the creation and insertion in one step, use the convenience function W(TextBuffer)->create_child_anchor().
- Methodget_deleted
intget_deleted()- Description
Determines whether a child anchor has been deleted from the buffer.
Class GTK2.TextIter
- Description
A TextIter.
- Methodbackward_char
intbackward_char()- Description
Moves backward by one character offset. Returns true if the movement was possible; if it was the first in the buffer (character offset 0), backward_char() returns false for convenience when writing loops.
- Methodbackward_chars
intbackward_chars(intcount)- Description
Moves count characters backward, if possible (if count would mmove past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if it didn't move, or moved onto the end iterator, then false is returned. If count is 0, the function does nothing and returns false.
- Methodbackward_cursor_position
intbackward_cursor_position()- Description
Like forward_cursor_position(), but moves backward.
- Methodbackward_cursor_positions
intbackward_cursor_positions(intcount)- Description
Moves up to count cursor positions.
- Methodbackward_line
intbackward_line()- Description
Moves to the start of the previous line. Returns true if this iter could be moved; i.e. if iter was at character offset 0, this function returns false. Therefore if it was already on line 0, but not at the start of the line, it is snapped to the start of the line and the function returns true. (Note that this implies that in a loop calling this function, the line number may not change on every iteration, if your first iteration is on line 0.)
- Methodbackward_search
arraybackward_search(stringstr,intflags,GTK2.TextIterlimit)- Description
Same as forward_search(), but searches backward.
- Methodbackward_sentence_start
intbackward_sentence_start()- Description
Moves backward to the previous sentence start.
- Methodbackward_sentence_starts
intbackward_sentence_starts(intcount)- Description
Call backward_sentence_start() count times.
- Methodbackward_to_tag_toggle
intbackward_to_tag_toggle(GTK2.TextTagtag)- Description
Moves backward to the next toggle. See forward_to_tag_toggle().
- Methodbackward_visible_cursor_position
intbackward_visible_cursor_position()- Description
Moves backward to the previous visible cursor position.
- Methodbackward_visible_cursor_positions
intbackward_visible_cursor_positions(intcount)- Description
Moves up to count visible cursor positions.
- Methodbackward_visible_line
intbackward_visible_line()- Description
Moves to the start of the previous visible line. Returns TRUE if iter could be moved; i.e. if iter was at character offset 0, this function returns FALSE. Therefore if iter was alreayd on line 0, but not at the start of the line, iter is snapped to the start of the line and the function returns TRUE. (Note that this implies that in a loop calling this function, the line number may not change on every iteration, if your first iteration is on line 0).
- Methodbackward_visible_lines
intbackward_visible_lines(intcount)- Description
Moves count visible lines backward, if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then FALSE is returned. If count is 0, the function does nothing and returns FALSE. If count is negative, moves forward by 0 - count lines.
- Methodbackward_visible_word_start
intbackward_visible_word_start()- Description
Moves backward to the previous visible word start.
- Methodbackward_visible_word_starts
intbackward_visible_word_starts(intcount)- Description
Call backward_visible_word_start() count times
- Methodbackward_word_start
intbackward_word_start()- Description
Moves backward to the previous word start.
- Methodbackward_word_starts
intbackward_word_starts(intcount)- Description
Calls backward_word_start() up to count times.
- Methodbegins_tag
intbegins_tag(GTK2.TextTagtag)- Description
Returns true if tag is toggled on at exactly this point. If tag is omitted, returns true if any tag is toggled on at this point. Note that begins_tag() returns true if this iter is the start of the tagged range; has_tag() tells you whether an iterator is within a tagged range.
- Methodcan_insert
intcan_insert(intdefault_editability)- Description
Considering the default editability of the buffer, and tags that affect editability, determines whether text inserted here would be editabled. If text inserted here would be editabled then the user should be allowed to insert text here. insert_interactive() uses this function to decide whether insertions are allowed at a given position.
- Methodcompare
intcompare(GTK2.TextIterrhs)- Description
Returns -1 if this iterator is less than rhs, 1 if greater than, and 0 if they're equal. Ordering is in character offset order, i.e. the first character in the buffer is less than the second character in the buffer.
- Methodeditable
inteditable(intdefault_setting)- Description
Returns whether the character at this location is within an editable region of text. Non-editable text is "locked" and can't be changed by the user via W(TextView). This function is simply a convenience wrapper around get_attributes(). If no tags applied to this text editability, default_setting will be returned.
You don't want to use this function to decide whether text can be inserted here, because for insertion you don't want to know whether the char at iter is inside an editable range, you want to know whether a new characer inserted here would be inside an editable range. Use can_insert() to handle this case.
- Methodends_line
intends_line()- Description
Returns true if iter points to the start of the paragraph delimiter characters for a line (delimiters will be either a newline, a carriage return, a carriage return followed by a newline, or a Unicode paragraph separator character). Note that an iterator pointing to the \n of a \r\n pair will not be counted as the end of a line, the line ends before the \r. The end iterator is considered to be at the end of a line, even though there are no paragraph delimiter chars there.
- Methodends_tag
intends_tag(GTK2.TextTagtag)- Description
Returns true if tag is toggled off at exactly this point. If tag is omitted, returns true if any tag is toggled off at this point. Not that ends_tag() returns true if this iter it at the end of the tagged range; has_tag() tells you whether an iterator is within a tagged range.
- Methodends_word
intends_word()- Description
Determines whether this iter ends a natural-language word. Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).
- Methodequal
intequal(GTK2.TextIterrhs)- Description
Tests whether two iterators are equal, using the fastest possible mechanism. This function is very fast; you can expect it to perform better than e.g. getting the character offset for each iterator and comparing offsets yourself. Also, it's a bit faster than compare().
- Methodforward_char
intforward_char()- Description
Moves this iterator forward by one character offset. Note that images embedded in the buffer occopy 1 character slot, to forward_char() may actually move onto an image instead of a character, if you have images in your buffer. If this iterator is the end iterator or one character before it, it will now point at the end iterator, and forward_char() returns false for convenience when writing loops.
- Methodforward_chars
intforward_chars(intcount)- Description
Moves count characters if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the new position is different from its original position, and dereferenceable (the last iterator in the buffer is not). If count is 0, the function does nothing and returns false.
- Methodforward_cursor_position
intforward_cursor_position()- Description
Moves this iterator forward by a single cursor position. Cursor positions are (unsurprisingly) positions where the cursor can appear. Perhaps surprisingly, there may not be a cursor position between all characters. The most common example for European languages would be a carriage return/newline sequence. For some Unicode characters, the equivalent of say the letter "a" with an accent mark will be represented as two characters, first the letter then a "combining mark" that causes the accent to be rendered; so the cursor can't go between those two characters. See also Pango.LogAttr and pango_break().
- Methodforward_cursor_positions
intforward_cursor_positions(intcount)- Description
Moves up to count cursor positions.
- Methodforward_line
intforward_line()- Description
Moves to the start of the next line. Returns true if there was a next line to move to, and false if this iter was simply moved to the end of the buffer and is now not dereferenceable, or if it was already at the end of the buffer.
- Methodforward_lines
intforward_lines(intcount)- Description
Moves count lines forward, if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then false is returned. If count is 0, the function does nothing and returns false. If count is negative, moves backward by 0 - count lines.
- Methodforward_search
arrayforward_search(stringstr,intflags,GTK2.TextIterlimit)- Description
Searches forward for str. Returns two GTK2.TextIter objects, one pointing to the first character of the match, and the second pointing to the first character after the match. The search will not continue past limit. Note that a search is a linear or O(n) operation, so you may wish to use limit to avoid locking up your UI on large buffers.
If the GTK2.TEXT_SEARCH_VISIBLE_ONLY flag is present, the match may have invisible text interspersed in str, i.e. str will be a possibly non-contiguous subsequence of the matched range. Similarly, if you specify GTK2.TEXT_SEARCH_TEXT_ONLY, the match may have pixbufs or child widgets mixed inside the matched range. If these flags are not given, the match must be exact; the special 0xFFFC character in str will match embedded pixbufs or child widgets.
- Methodforward_sentence_end
intforward_sentence_end()- Description
Moves forward to the next sentence end.
- Methodforward_sentence_ends
intforward_sentence_ends(intcount)- Description
Call forward_sentence_ends() count times.
- Methodforward_to_end
GTK2.TextIterforward_to_end()- Description
Moves forward to the "end iterator", which points one past the last valid character in the buffer. get_char() called on the end iterator returns 0, which is convenient for writing loops.
- Methodforward_to_line_end
intforward_to_line_end()- Description
Moves the iterator to point to the paragraph delimiter characters, which will be either a newline, a carriage return, a carriage return/newline sequence, or the Unicode paragraph separator character. If the iterator is already at the paragraph delimiter characters, moves to the paragraph delimiter characters for the next line. If iter is on the last line in the buffer, which does not end in paragraph delimiters, moves to the end iterator (end of the last line), and returns false.
- Methodforward_to_tag_toggle
intforward_to_tag_toggle(GTK2.TextTagtag)- Description
Moves forward to the next toggle (on or off) of tag, or to the next toggle of any tag if tag is omitted. If no matching tag toggles are found, returns false, otherwise true. Does not return toggles located at this iter, only toggles after. Sets this iter to the location of the toggle, or to the end of the buffer if no toggle is found.
- Methodforward_visible_cursor_position
intforward_visible_cursor_position()- Description
Moves forward to the next visible cursor position.
- Methodforward_visible_cursor_positions
intforward_visible_cursor_positions(intcount)- Description
Moves up to count visible cursor positions.
- Methodforward_visible_line
intforward_visible_line()- Description
Moves to the start of the next visible line. Returns TRUE if there was a next line to move to, and FALSE if iter was simply moved to the end of the buffer and is now not dereferenceable, or if iter was already at the end of the buffer.
- Methodforward_visible_lines
intforward_visible_lines(intcount)- Description
Moves count visible lines forward, if possible (if count would move past the start or end of the buffer, moves to the start or end of the buffer). The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn't move, or moved onto the end iterator, then FALSE is returned. If count is 0, the function does nothing and returns FALSE. If count is negative, moves backward by 0 - count lines.
- Methodforward_visible_word_end
intforward_visible_word_end()- Description
Moves forward to the next visible word end.
- Methodforward_visible_word_ends
intforward_visible_word_ends(intcount)- Description
Call forward_visible_word_end() count times.
- Methodforward_word_ends
intforward_word_ends(intcount)- Description
Calls forward_word_end() up to count times.
- Methodget_buffer
GTK2.TextBufferget_buffer()- Description
Returns the W(TextBuffer) this iterator is associated with.
- Methodget_bytes_in_line
intget_bytes_in_line()- Description
Returns the number of bytes in the line, including the paragraph delimiters.
- Methodget_char
intget_char()- Description
Returns the Unicode character at this iterator. If the element at this iterator is a non-character element, such as an image embedded in the buffer, the Unicode "unknown" character 0xFFFc is returned.
- Methodget_chars_in_line
intget_chars_in_line()- Description
Returns the number of characters in the line, including the paragraph delimiters.
- Methodget_child_anchor
GTK2.TextChildAnchorget_child_anchor()- Description
If this location contains a child anchor, the anchor is returned.
- Methodget_line_index
intget_line_index()- Description
Returns the byte index of the iterator, counting from the start of a newline-terminated line. Rember that W(TextBuffer) encodes text in UTF-8, and that characters can require a variable number of bytes to represent.
- Methodget_line_offset
intget_line_offset()- Description
Returns the character offset of the iterator, counting from the start of a newline-terminated line.
- Methodget_marks
arrayget_marks()- Description
Returns a list of W(TextMark) at this location. Because marks are not iterable (they don't take up any "space" in the buffer, they are just marks in between iterable locations), multiple marks can exist in the same place. The returned list is not in any meaningful order.
- Methodget_pixbuf
GTK2.GdkPixbufget_pixbuf()- Description
If the element at iter is a pixbuf, it is returned.
- Methodget_slice
stringget_slice(GTK2.TextIterend)- Description
Returns the text in the given range. A "slice" is an array of characters including the Unicode "unknown" character 0xFFFC for iterable non-character elements in the buffer, such as images. Because images are encoded in the slice, byte and character offsets in the returned array will correspond to bytes offsets in the text buffer. Note that 0xFFFC can occur in normal text as well, so it is not a reliable indicator that a pixbuf or widget is in the buffer.
- Methodget_tags
arrayget_tags()- Description
Returns a list of tags that apply to iter, in ascending order of priority (highest-priority tags are last).
- Methodget_text
stringget_text(GTK2.TextIterend)- Description
Returns text in the given range. If the range contains non-text elements such as images, the character and byte offsets in the returned string will not correspond to character and bytes offsets in the buffer.
- Methodget_toggled_tags
arrayget_toggled_tags(inttoggled_on)- Description
Returns a list of W(TextTag) that are toggled on or off at this point. (If toggled_on is true, the list contains tags that are toggled on). If a tag is toggled on at this iterator, then some non-empty range of characters following this iter has that tag applied to it. If a tag is toggled off, then some non-empty range following this iter does not have the tag applied to it.
- Methodget_visible_line_index
intget_visible_line_index()- Description
Returns the number of bytes from the start of the line to this iter, not counting bytes that are invisible due to tags with the invisible flag toggled on.
- Methodget_visible_line_offset
intget_visible_line_offset()- Description
Returns the offset in characters from the start of the line, not not counting characters that are invisible due to tags with the invisible tag toggled on.
- Methodget_visible_slice
stringget_visible_slice(GTK2.TextIterend)- Description
Like get_slice(), but invisible text is not included.
- Methodget_visible_text
stringget_visible_text(GTK2.TextIterend)- Description
Like get_text(), but invisible text is not include.
- Methodhas_tag
inthas_tag(GTK2.TextTagtag)- Description
Returns true if this iterator is within a range tagged with tag.
- Methodin_range
intin_range(GTK2.TextIterstart,GTK2.TextIterend)- Description
Checks whether this iterator falls in the range [start,end). start and end must be in ascending order.
- Methodinside_sentence
intinside_sentence()- Description
Determines whether this is inside a sentence (as opposed to int between two sentences, e.g. after a period and before the first letter of the next sentence). Sentence boundaries are determined by Pango and should be correct for nearly language (if not, the correct fix would be to the Pango text boundary algorithms).
- Methodinside_word
intinside_word()- Description
Determines whether this iter is inside a natural-language word ass opposed to say inside some whitespace).
- Methodis_cursor_position
intis_cursor_position()- Description
See forward_cursor_position() or Pango.LangAttr or pango_break() for details on what a cursor position is.
- Methodis_end
intis_end()- Description
Returns true if this location is the end iterator, i.e. one past the last dereferenceable iterator in the buffer. is_end() is the most efficient way to check whether an iterator is the end iterator.
- Methodis_start
intis_start()- Description
Returns true if this is the first iterator in the buffer, that is if it has a character offset of 0.
- Methodorder
GTK2.TextIterorder(GTK2.TextItersecond)- Description
Swaps this iter for second if second comes first in the buffer. That is, ensures that this iterator and second are in sequence. Most text buffer functions that take a range call this automatically on your behalf, so there's no real reason to call it yourself in those cases. There are some exceptions, such as in_range(), that expect a pre-sorted range.
- Methodset_line
GTK2.TextIterset_line(intline_number)- Description
Moves the iterator to the start of the line line_number. If line_number is negative or larger than the number of lines in the buffer, moves to the start of the last line in the buffer.
- Methodset_line_index
GTK2.TextIterset_line_index(intindex)- Description
Same as set_line_offset(), but works with a byte index. The given byte index must be at the start of a character, it can't be in the middle of a UTF-8 encoded character.
- Methodset_line_offset
GTK2.TextIterset_line_offset(intoffset)- Description
Moves iterator within a line, to a new character (not byte) offset. The given character offset must be less than or equal to the number of characters in the line; if equal, iterator moves to the start of the next line. See set_line_index() if you have a byte index rather than a character offset.
- Methodset_offset
GTK2.TextIterset_offset(intchar_offset)- Description
Sets to point to char_offset. char_offset counts from the start of the entire text buffer, starting with 0.
- Methodset_visible_line_index
GTK2.TextIterset_visible_line_index(intindex)- Description
Same as set_line_index(), but works with visible byte index. The given byte index must be at the start of a character, it can't be in the middle of a UTF-8 encoded character.
- Methodset_visible_line_offset
GTK2.TextIterset_visible_line_offset(intoffset)- Description
Like set_line_offset(), but the offset is in visible characters, i.e. text with a tag making it invisible is not counted in the offset.
- Methodstarts_line
intstarts_line()- Description
Returns true if this iter begins a paragraph, i.e. if get_line_offset() would return 0. However this function is potentially more efficient than get_line_offset() because it doesn't have to computer the offset, it just has to see whether it's 0.
- Methodstarts_word
intstarts_word()- Description
Determines whether this iter begins a natural-language word. Word breaks are determined by Pango and should be correct for nearly any language (if not, the correct fix would be to the Pango word break algorithms).
Class GTK2.TextMark
- Description
Marks for the text.
- Methodget_buffer
GTK2.TextBufferget_buffer()- Description
Gets the buffer this mark is located inside, or empty if the mark is deleted.
- Methodget_deleted
intget_deleted()- Description
Returns true if the mark has been removed from its buffer with delete_mark(). Marks can't be used once deleted.
- Methodset_visible
GTK2.TextMarkset_visible(intsetting)- Description
Sets the visibility of the mark; the insertion point is normally visible, i.e. you can see it as a vertical bar. Also the text widget uses a visible mark to indicate where a drop will occur when dragging-and-dropping text. Most other marks are not visible. Marks are not visible by default.

Class GTK2.TextTagTable
- Description
Table of text tags.
Signals: tag_added
tag_changed

- Methodadd
GTK2.TextTagTableadd(GTK2.TextTagtag)- Description

- Methodadd_child_at_anchor
GTK2.TextViewadd_child_at_anchor(GTK2.Widgetchild,GTK2.TextChildAnchoranchor)- Description
Adds a child widget in the text buffer, at the given anchor.
- Methodadd_child_in_window
GTK2.TextViewadd_child_in_window(GTK2.Widgetchild,intwintype,intxpos,intypos)- Description
Adds a child at fixed coordinates in one of the text widget's windows. The window must have nonzero size (see GTK2.TextView->set_border_window_size()). Note that the child coordinates are given relative to the GDK2.Window in question, and that these coordinates have no sane relationship to scrolling. When placing a child in GTK2.TEXT_WINDOW_WIDGET, scrolling is irrelevant, the child floats above all scrollable areas. But when placing a child in one of the scrollable windows (border windows or text window), you'll need to compute the child's correct position in buffer coordinates any time scrolling occurs or buffer changes occur, and then call GTK2.TextView->move_child() to update the child's position. Unfortunately there's no good way to detect that scrolling has occurred, using the current API; a possible hack would be to update all child positions when the scroll adjustments change or the text buffer changes.
- Methodbackward_display_line
intbackward_display_line(GTK2.TextIteriter)- Description
See forward_display_line().
- Methodbackward_display_line_start
intbackward_display_line_start(GTK2.TextIteriter)- Description
Moves the iter backward to the next display line start.
- Methodbuffer_to_window_coords
arraybuffer_to_window_coords(intwintype,intbuffer_x,intbuffer_y)- Description
Converts coordinate (buffer_x,buffer_y) to coordinates for the window win, and returns the results. wintype is one of
TEXT_WINDOW_BOTTOM,TEXT_WINDOW_LEFT,TEXT_WINDOW_PRIVATE,TEXT_WINDOW_RIGHT,TEXT_WINDOW_TEXT,TEXT_WINDOW_TOPandTEXT_WINDOW_WIDGET.
- Methodcreate
GTK2.TextViewGTK2.TextView(GTK2.TextBufferbuffer_or_props)- Description
Create a new W(TextView).
- Methodforward_display_line
intforward_display_line(GTK2.TextIteriter)- Description
Moves iter forward by one display (wrapped) line. A display line is different from a paragraph. Paragraphs are separated by newlines or other paragraph separator characters. Display lines are created by line-wrapping a paragraph. If wrapping is turned off, display lines and paragraphs will be the same. Display lines are divided differently for each view, since they depend on the view's width; paragraphs are the same in all view, since they depend on the contents of the W(TextBuffer).
- Methodforward_display_line_end
intforward_display_line_end(GTK2.TextIteriter)- Description
Moves the iter forward to the next display line end.
- Methodget_accepts_tab
intget_accepts_tab()- Description
Returns whether pressing the Tab key inserts a tab character.

Class GTK2.Tooltips
- Description
Tooltips are the messages that appear next to a widget when the mouse pointer is held over it for a short amount of time. They are especially helpful for adding more verbose descriptions of things such as buttons in a toolbar.
An individual tooltip belongs to a group of tooltips. A group is created with a call to GTK2.Tooltips(). Every tooltip in the group can then be turned off with a call to disable() and enabled with enable().
The length of time the user must keep the mouse over a widget before the tip is shown, can be altered with set_delay(). This is set on a 'per group of tooltips' basis.
To assign a tip to a particular W(Widget), set_tip() is used.
The default appearance of all tooltips in a program is determined by the current gtk theme that the user has selected. To change the tooltip appearance manually, use set_colors(). Again, this is per group of tooltips.

Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.
If row_align exists, then col_align must exist, otherwise neither will be used. If neither are used, the tree does the minimum amount of work to scroll the cell onto the screen. This means that the cell will be scrolled to the edge closest to its current position. If the cell is currently visible on the screen, nothing is done.
This function only works if the model is set, and path is a valid row on the model. If the model changes before the view is realized, the centered path will be modifed to reflect this change.

Sets the model. If this TreeView already has a model set, it will remove it before setting the new model.
- Methodset_reorderable
GTK2.TreeViewset_reorderable(intreorderable)- Description
This function is a convenience function to allow you to reorder models. If reorderable is true, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model's "row-inserted" and "row-deleted" signals.
This function does not give you any degree of control over the order -- any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.
- Methodset_row_separator_func
GTK2.TreeViewset_row_separator_func(function(:void)f,mixeduser_data)- Description
Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is 0 no separators are drawn. This is the default value.

By default, GTK2+ will then render the tree with alternating row colors. Do not use it just because you prefer the appearance of the ruled tree; that's a question for the theme. Some themes will draw tree rows in alternating colors even when rules are turned off, and users who prefer that appearance all the time can choose those themes. You should call this function only as a semantic hint to the theme engine that your tree makes alternating colors usefull from a functional standpoint (since it has lots of columns, generally).
- Methodset_search_column
GTK2.TreeViewset_search_column(intcolumn)- Description
Sets column as the column where the interactive search code should search in.

Class GTK2.Widget
- Description
The basic widget, inherited (directly or indirectly) by all widgets. Thus, all functions and signals defined in this widget work on all widgets.
One of the most important functions in this class is 'show', it lets GTK2 know that we are done setting the attributes of the widget, and it is ready to be displayed. You may also use hide to make it disappear again. The order in which you show the widgets is not important, but I suggest showing the toplevel window last so the whole window pops up at once rather than seeing the individual widgets come up on the screen as they're formed. The children of a widget (a window is a widget too) will not be displayed until the window itself is shown using the show() function.

- Methodget_snapshot
GTK2.GdkPixmapget_snapshot(GTK2.GdkRectangleclip_rect)- Description
Create a GDK2.Pixmap of the contents of the widget and its children
Works even if the widget is obscured. The depth and visual of the resulting pixmap is dependent on the widget being snapshot and likely differs from those of a target widget displaying the pixmap. The function GDK2.Pixbuf->get_from_drawable() can be used to convert the pixmap to a visual independent representation.
The snapshot are used by this function is the widget's allocation plus any extra space occupied by additional windows belonging to this widget (such as the arrows of a spin button). Thus, the resulting snapshot pixmap is possibly larger than the allocation.
If clip_rect is non-null, the resulting pixmap is shrunken to match the specified clip_rect. The (x,y) coordinates of clip_rect are interpreted widget relative. If width or height of clip_rect are 0 or negative, the width or height of the resulting pixmap will be shurnken by the respective amount. For instance, a clip_rect (+5,+5,-10,-10) will chop off 5 pixels at each side of the snapshot pixmap. If non-null, clip_rect will contain the exact widget-relative snapshot coordinates upon return. A clip_rect of (-1,-1,0,0) can be used to preserve the auto-grown snapshot area and use clip_rect as a pure output parameter.
The return pixmap can be 0, if the resulting clip_area was empty.

GTK2.GdkWindowget_window()- Description
Returns the widget's window if it is realized, other NULL.
- Methodgrab_default
GTK2.Widgetgrab_default()- Description
Causes this widget to become the default widget.
- Methodgrab_focus
GTK2.Widgetgrab_focus()- Description
Causes this widget to have the keyboard focus. This widget must be a focusable widget, such as a GTK2.Entry; something like GTK2.Frame won't work.
- Methodhas_screen
inthas_screen()- Description
Checks whether there is a GDK2.Screen associated with this widget.
- Methodinput_shape_combine_mask
GTK2.Widgetinput_shape_combine_mask(GTK2.GdkBitmapshape_mask,intoffset_x,intoffset_y)- Description
Sets an input shape for this widget's GDK2.Window.
- Methodis_ancestor

Determines whether this widget is somewhere inside ancestor.
- Methodis_composited
intis_composited()- Description
Whether this widget can rely on having its alpha channel drawn correctly.
- Methodis_focus
intis_focus()- Description
Determines if the widget is the focus widget within its toplevel. (This does not mean that the HAS_FOCUS flag is necessarily set; HAS_FOCUS will only be set if the toplevel widget additionally has the input focus.
- Methodkeynav_failed
intkeynav_failed(intdirection)- Description
This function should be called whenever keyboard navigation within a single widget hits a boundary. The function emits the "keynav-changed" signal on the widget and its return value should be interpreted in a way similar to the return value of widget->child_focus():
When TRUE is returned, stay in the widget, the failed keyboard navigation is Ok and/or there is nowhere we can/should move the focus to.
When FALSE is returned, the caller should continue with keyboard navigation outside the widget, e.g. by calling widget->child_focus() on the widget's toplevel.
The default ::keynav-failed handler returns TRUE for GTK_DIR.TAB_FORWARD and GTK_DIR.TAB_BACKWARD. For the other values of GtkDirectionType, it looks at the "gtk-keynav-cursor-only"" setting and returns FALSE if the setting is TRUE. This way the entire user interface becomes cursor-navigatable on input devices such as mobile phones which only have cursor keys but no tab key.
Whenever the default handler returns TRUE, it also calls widget->error_bell() to notify the user of the failed keyboard navigation.
- Methodlist_mnemonic_lables
arraylist_mnemonic_lables()- Description
Returns a list of the widgets, normally labels, for which this widget is the target of a mnemonic.
- Methodmodify_base

Sets the foreground color of the widget in a particular state. state is one of
STATE_ACTIVE,STATE_INSENSITIVE,STATE_NORMAL,STATE_PRELIGHTandSTATE_SELECTED. color can be omitted to undo the effect of a previous call.
- Methodmodify_text
GTK2.Widgetmodify_text(intstate,GTK2.GdkColorcolor)- Description
Sets the text color of the widget in a particular state. See modify_fg().
- Methodpath
stringpath()- Description
Obtains the full path. The path is simply the name of a widget and all its parents in the container hierarchy, separated by periods.
- Methodqueue_draw
GTK2.Widgetqueue_draw()- Description
Equivalent to calling queue_draw_area() for the entire area of the widget.
- Methodqueue_draw_area
GTK2.Widgetqueue_draw_area(intx,inty,intwidth,intheight)- Description
Invalidates the rectangular area defined by x,y,width,height by calling GDK2.Window->invalidate_rect() on the widget's window and all its child windows. Once the main loop becomse idle (after the current batch of events has been processed, roughly), the window will receive expose events for the union of all regions that have been invalidated.
- Methodqueue_resize
GTK2.Widgetqueue_resize()- Description
This function is only for use in widget implementations. Flags a widget to have its size renegotiated; should be called when a widget for some reason has a new size request. For example, when you change the text in a W(Label), GTK2.Label queues a resize to ensure there's enough space for the new text.
- Methodqueue_resize_no_redraw
GTK2.Widgetqueue_resize_no_redraw()- Description
This function works like queue_resize(), except that the widget is not invalidated.

- Methodrender_icon
GTK2.GdkPixbufrender_icon(stringstock_id,intsize,stringdetail)- Description
A convenience function that uses the theme engine and rc file settings to look up stock_id and render it to a pixbuf. stock_id should be a stock icon ID such as GTK2.STOCK_OPEN or GTK2.STOCK_OK. size should be a size such as GTK2.ICON_SIZE_MENU. detail should be a string that identifies the widget or code doing the rendering, so that theme engines can special-case rendering for that widget or code.
The pixels in the returned GDK2.Pixbuf are shared with the rest of the application and should not be modified.
- Methodreparent
GTK2.Widgetreparent(GTK2.Widgetnew_parent)- Description
Moves a widget from one W(Container) to another.
- Methodreset_shapes
GTK2.Widgetreset_shapes()- Description
Recursively resets the shape on this widget and its descendants.
- Methodset_accel_path

- Methodset_composite_name
GTK2.Widgetset_composite_name(stringname)- Description
Sets a widget's composite name.
- Methodset_direction
GTK2.Widgetset_direction(intdir)- Description
Sets the reading direction. This direction controls the primary direction for widgets containing text, and also the direction in which the children of the container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification).
- Methodset_events
GTK2.Widgetset_events(intevents)- Description
Sets the event mask for a widget. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget's functionality, so be careful. This function must be called while a widget is unrealized. Consider add_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can't be used with GTK2.NO_WINDOW widgets; to get events on those widgets, place them inside a GTK2.EventBox and receive events on the event box.
- Methodset_extension_events
GTK2.Widgetset_extension_events(intmode)- Description
Sets the extension events mask to mode. One of
GDK_EXTENSION_EVENTS_ALL,GDK_EXTENSION_EVENTS_CURSORandGDK_EXTENSION_EVENTS_NONE
- Methodset_flags
GTK2.Widgetset_flags(intflags)- Description
Set certain flags, such as GTK2.CAN_DEFAULT.
- Methodset_name
GTK2.Widgetset_name(stringname)- Description
Widgets can be named, which allows you to refer to them from a gtkrc file. You can apply a style to widgets with a particular name in the gtkrc file.
- Methodset_no_show_all
GTK2.Widgetset_no_show_all(intno_show_all)- Description
Sets the "no-show-all" property, which determines whether calls to show_all() and hide_all() will affect this widget.
- Methodset_parent
GTK2.Widgetset_parent(GTK2.Widgetparent)- Description
Sets the container as the parent of this widget.
- Methodset_parent_window
GTK2.Widgetset_parent_window(GTK2.GdkWindowparent)- Description
Sets a non default parent window for this widget.
- Methodset_scroll_adjustments
GTK2.Widgetset_scroll_adjustments(GTK2.Adjustmenthadj,GTK2.Adjustmentvadj)- Description
For widgets that support scrolling, sets the scroll adjustments. For widgets that don't support scrolling, does nothing. Widgets that don't support scrolling can be scrolled by placing them in a W(Viewport), which does support scrolling.
- Methodset_sensitive
GTK2.Widgetset_sensitive(intsensitive)- Description
Sets the sensitivity. A widget is sensitive is the user can interact with it. Insensitive widgets are "grayed out" and the user can't interact with them. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits.
- Methodset_size_request
GTK2.Widgetset_size_request(intwidth,intheight)- Description
Sets the minimum size of a widget; that is, the widget's size request will be width by height. You can use this function to force a widget to be either larger or smaller than it normally would be.
In most cases, set_default_size() is a better choice for toplevel windows than this function; setting the default size will still allow users to shrink the window. Setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, set_geometry_hints() can be a useful function as well.
Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct.
The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it request.
If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead.
Widgets can't actually be allocated a size less than 1x1, but you can pass 0,0 to this function to mean "as small as possible".
- Methodset_tooltip_markup
GTK2.Widgetset_tooltip_markup(stringmarkup)- Description
Sets markup as the contents of the tooltip
- Methodset_tooltip_text
GTK2.Widgetset_tooltip_text(stringtext)- Description
Sets text as the contents of the tooltip.
- Methodset_tooltip_window
GTK2.Widgetset_tooltip_window(GTK2.Windowwindow)- Description
Replaces the default, usually yellow, window used for displaying tooltips.
- Methodshape_combine_mask
GTK2.Widgetshape_combine_mask(GTK2.GdkBitmapshape_mask,intoffset_x,intoffset_y)- Description
Sets a shape for a widget's GDK2.Window. This allows for transparent window, etc.
- Methodshow
GTK2.Widgetshow()- Description
Show the widget. Most (almost all) widgets must be shown to be visible on the screen.
- Methodshow_now
GTK2.Widgetshow_now()- Description
Shows a widget. If the widget is an unmapped toplevel widget (i.e. a GTK2.Window that has not yet been shown), enter the main loop and wait for the window to actually be mapped. Be careful; because the main loop is running, anything can happen during this function.
- Methodstyle_get_property
mixedstyle_get_property(stringname)- Description
Gets the value of the style property called name.
- Methodthaw_child_notify
GTK2.Widgetthaw_child_notify()- Description
Reverts the effect of a previous call to freeze_child_notify().
Class GTK2.Window
- Description
The basic window. Nothing much to say about it. It can only contain one child widget. Show the main window last to avoid annoying flashes when the subwidget (and it's subwidgets) are added to it, this is done automatically by calling 'window->show_all' when you are done with your widget packing.

- Methodadd_accel_group
GTK2.Windowadd_accel_group(GTK2.AccelGroupgroup)- Description
This function adds an accelerator group to the window. The shortcuts in the table will work in the window, it's child, and all children of it's child that do not select keyboard input.
- Methodadd_mnemonic
GTK2.Windowadd_mnemonic(intkeyval,GTK2.Widgettarget)- Description
Adds a mnemonic to this window.
- Methodbegin_move_drag
GTK2.Windowbegin_move_drag(intbutton,introot_x,introot_y,inttimestamp)- Description
Starts moving a window. This function is used if an application has window movement grips.
- Methodbegin_resize_drag
GTK2.Windowbegin_resize_drag(intedge,intbutton,introot_x,introot_y,inttimestamp)- Description
Starts resizing a window. This function is used if an application has window resizing controls. When GDK can support it, the resize will be done using the standard mechanism for the window manager or windowing system.
- Methodcreate
GTK2.WindowGTK2.Window(int|mappingprops)- Description
Argument is one of
WINDOW_POPUPandWINDOW_TOPLEVEL, or a mapping of allowed properties.
- Methodfullscreen
GTK2.Windowfullscreen()- Description
Asks to place this window in the fullscreen state. Same caveats iconify().
- Methodget_decorated
intget_decorated()- Description
Returns whether the window has been set to have decorations such as a title bar.
- Methodget_default_size
mappingget_default_size()- Description
Gets the default size of the window. A value of -1 for the width or height indicates that a default size has not been explicitly set for that dimeension, so the "natural" size of the window will be used.
- Methodget_deletable
intget_deletable()- Description
Returns whether the window has been set to have a close button.
- Methodget_destroy_with_parent
intget_destroy_with_parent()- Description
Returns whether the window will be destroyed with its transient parent.
- Methodget_focus
GTK2.Widgetget_focus()- Description
Retrieves the current focused widget within the window. Note that this is the widget that would have the focus if the toplevel window focused; if the toplevel window is not focused then has_focus() will not be true for the widget.
- Methodget_group
GTK2.WindowGroupget_group()- Description
Returns the group for this widget or the default group.
- Methodget_icon_list
arrayget_icon_list()- Description
Retrieves the list of icons set by set_icon_list().
- Methodget_icon_name
stringget_icon_name()- Description
Returns the name of the themed icon for the window.
- Methodget_mnemonic_modifier
intget_mnemonic_modifier()- Description
Returns the mnemonic modifier for this window.
- Methodget_position
mappingget_position()- Description
This function returns the position you need to pass to move() to keep this window in its current position. This means that the meaning of the returned value varies with window gravity.
If you haven't changed the window gravity, its gravity will be GDK2.GRAVITY_NORTH_WEST. This means that get_position() gets the position of the top-left corner of the window manager frame for the window. move() sets the position of this same top-left corner.
get_position() is not 100% reliable because X does not specify a way to obtain the geometry of the decorations placed on a window by the window manager. Thus GTK+ is using a "best guess" that works with most window managers.
Moreover, nearly all window managers are historically broken with respect to their handling of window gravity. So moving a window to its current position as returned by get_position() tends to result in moving the window slightly. Window managers are slowly getting better over time.
If a window has gravity GDK2.GRAVITY_STATIC the window manager frame is not relevant, and thus get_position() will always produc accurate results. However you can't use static gravity to do things like place a window in a corner of the screen, because static gravity ignores the window manager decorations.
If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state.
- Methodget_skip_pager_hint
intget_skip_pager_hint()- Description
Gets the value set by set_skip_pager_hint().
- Methodget_skip_taskbar_hint
intget_skip_taskbar_hint()- Description
Gets the value set by set_skip_taskbar_hint().
- Methodget_transient_for
GTK2.Windowget_transient_for()- Description
Fetches the transient parent for this window.
- Methodhas_toplevel_focus
inthas_toplevel_focus()- Description
Returns whether the input focus is within this window. For real toplevel windows, this is identical to is_active(), but for embedded windows, like W(Plug), the results will differ.
- Methodiconify
GTK2.Windowiconify()- Description
Asks to iconify (minimize) this window. Note that you shouldn't assume the window is definitely iconified afterward, because other entities (e.g. the user or window manager) could deiconify it again, or there may not be a window manager in which case iconification isn't possible, etc.
- Methodis_active
intis_active()- Description
Returns whether the window is part of the current active toplevel. (That is, the toplevel window receiving keystrokes.) The return value is true if the window is active toplevel itself, but also if it is, say, a W(Plug) embedded in the active toplevel. You might use this function if you wanted to draw a widget differently in an active window from a widget in an inactive window().
- Methodmnemonic_activate
intmnemonic_activate(intkeyval,intmodifier)- Description
Activates the targets associated with the mnemonic. modifier is one of GDK2.SHIFT_MASK, GDK2.LOCK_MASK, GDK2.CONTROL_MASK, GDK2.MOD1_MASK, GDK2.MOD2_MASK, GDK2.MOD3_MASK, GDK2.MOD4_MASK, GDK2.MOD5_MASK, GDK2.BUTTON1_MASK, GDK2.BUTTON2_MASK, GDK2.BUTTON3_MASK, GDK2.BUTTON4_MASK GDK2.BUTTON5_MASK, GDK2.RELEASE_MASK, GDK2.MODIFIER_MASK
- Methodmove
GTK2.Windowmove(intx,inty)- Description
Asks the window manage to move the window to the given position. Window managers are free to ignore this; most window managers ignore request for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown.
Note: the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is position at the reference point.
By default the gravity is GDK2.GRAVITY_NORTH_WEST, so the reference point is simply the x,y supplied to move(). The top-left corner of the window decorations (aka window frame or border) will be place at x,y. Therefore, to position a window at the top left of the screen, you want to use the default gravity (which is GDK2.GRAVITY_NORTH_WEST) and move the window to 0,0.
To position a window at the bottom right corner of the screen, you would set GDK2.GRAVITY_SOUTH_EAST, which means that the reference point is at x + the window width and y + the window height, and the bottom-right corner of the window border will be placed at that reference point.
- Methodparse_geometry
intparse_geometry(stringgeometry)- Description
Parses a standard X geometry string.
- Methodpresent
GTK2.Windowpresent()- Description
Presents this window to the user. This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user's platform, window manager, and preferences.
If hidden, it calls show() as well.
- Methodpresent_with_time
GTK2.Windowpresent_with_time(inttimestamp)- Description
Presents a window to the user with a timestamp. See present().
- Methodremove_accel_group
GTK2.Windowremove_accel_group(GTK2.AccelGroupgroup)- Description
Reverses the effects of add_accel_group().
- Methodremove_mnemonic
GTK2.Windowremove_mnemonic(intkeyval,GTK2.Widgettarget)- Description
Removes a mnemonic from this window.
- Methodreshow_with_initial_size
GTK2.Windowreshow_with_initial_size()- Description
Hides the window, then reshows it, resetting the default size and position of the window.
- Methodresize
GTK2.Windowresize(intwidth,intheight)- Description
Resizes the window as if the user had done so, obeying geometry constraints.
- Methodset_accept_focus
GTK2.Windowset_accept_focus(intsetting)- Description
Windows may set a hint asking the desktop environment not to receive the input focus.
- Methodset_decorated
GTK2.Windowset_decorated(intsetting)- Description
Add title bar, resize controls, etc. Default is true, so you may only need to use this function if you want to remove decorations. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling show().
- Methodset_default
GTK2.Windowset_default(GTK2.Widgetchild)- Description
The default widget is the widget that's activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget. When setting (rather than unsetting) the default widget it's generally easier to call GTK2.Widget->grab_default() on the widget.
- Methodset_default_size
GTK2.Windowset_default_size(intwidth,intheight)- Description
Sets the default size of a window. If the window's "natural" size (its size request) is larger than the default, the default will be ignored. more generally, if the default size does not obey the geometry hints for the window (set_geometry_hints() can be used to set these explicitly), the default size will be clamped to the nearest permitted size.
Unlike set_size_request(), which sets a size request for a widget and thus would keep users from shrinking the window, this function only sets the initial size, just as if the user had resized the window themselves. Users can still shrink the window again as they normally would. Setting a default size of -1 means to use the "natural" default size (the size request of the window).
For more control over a window's initial size and how resizing works, investigate set_geometry_hints().
For some uses, resize() is a more appropriate function. resize() changes the current size of the window, rather than the size to be used on initial display. resize() always affects the window itself, not the geometry widget.
The default size of a window only affects the first time a window is shown; if a window is hidden and re-shown, it will remember the size it had prior to hiding, rather than using the default size.
Window scan't actually be 0x0 in size, they must be at least 1x1, but passing 0 for width and height is OK, resulting in a 1x1 default size.
- Methodset_deletable
GTK2.Windowset_deletable(intsetting)- Description
By default, windows have a close button in the window frame. Some window managers allow GTK+ to disable this button. If you set the deletable property to FALSE using this function, GTK+ will do its best to convince the window manager not to show a close button. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling show().
On Windows, this function always works, since there's no window manager policy involved.
- Methodset_destroy_with_parent
GTK2.Windowset_destroy_with_parent(intsetting)- Description
If setting is true, then destroying the transient parent of this window will also destroy the window itself. This is useful for dialogs that shouldn't persist beyond the lifetime of the main window they're associated with, for example.
- Methodset_focus
GTK2.Windowset_focus(GTK2.Widgetchild)- Description
If child is not the current focus widget, and is focusable, sets it as the focus widget for the window. If child is 0, unsets the focus widget for this window. To set the focus to a particular widget in the toplevel, it is usually more convenient to use GTK2.Widget->grab_focus() instead of this function.
- Methodset_focus_on_map
GTK2.Windowset_focus_on_map(intsetting)- Description
Windows may set a hint asking the desktop environment not to receive the input focus when the window is mapped.
- Methodset_geometry_hints
GTK2.Windowset_geometry_hints(GTK2.Widgetwidget,mappinggeometry)- Description
This function sets up hints about how a window can be resized by the user. You can set a minimum and maximum size; allowed resized increments (e.g. for xterm, you can only resize by the size of a character); aspect ratios; and more. geometry is a mapping with the following fields. Any field which is omitted is left as the default: ([ "min_width": int, "min_height": int, "max_width": int, "max_height": int, "base_width": int, "base_height": int, "width_inc": int, "height_inc": int, "min_aspect": float, "max_aspect": float, "win_gravity": int,
GDK_GRAVITY_CENTER,GDK_GRAVITY_EAST,GDK_GRAVITY_NORTH,GDK_GRAVITY_NORTH_EAST,GDK_GRAVITY_NORTH_WEST,GDK_GRAVITY_SOUTH,GDK_GRAVITY_SOUTH_EAST,GDK_GRAVITY_SOUTH_WEST,GDK_GRAVITY_STATICandGDK_GRAVITY_WEST]); min_width/min_height/max_width/max_height may be set to -1, and it will substitute the size request of the window or geometry widget. If the minimum size hint is not provided, it will use its requisition as the minimum size. If the minimum size is provided and a geometry widget is set, it will take the minimum size as the minimum size of the geometry widget rather than the entire window. The base size is treat similarly. min_width: minimum width of the window (-1 to use requisition) min_height: minimum height of window (-1 to use requisition) max_width: maximum width of window (-1 to use requisition) max_height: maximum height of window (-1 to use requisition) base_width: allow window widths are base_width+width_inc*N (-1 allowed) base_height: allowed window widths are base_height+height_inc*N (-1 allowed) width_inc: width resize increment height_inc: height resize increment min_aspect: minimum width/height ratio max_aspect: maximum width/height ratio win_gravity: window gravity
- Methodset_gravity
GTK2.Windowset_gravity(intgravity)- Description
Window gravity defines the meaning of coordinates passed to move().
The default window gravity is GDK2.GRAVITY_NORTH_WEST, which will typically "do what you mean."
- Methodset_icon
GTK2.Windowset_icon(GTK2.GdkPixbuficon)- Description
Sets up the icon representing this window. This icon is used when the window is minimized (also know as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts.
The icon should be provided in whatever size it was naturally drawn; that is, don't scale the image before passing it. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.
If you have your icon hand-drawn in multiple sizes, use set_icon_list(). Then the best size will be used.
- Methodset_icon_list
GTK2.Windowset_icon_list(arraylist)- Description
Set up the icons for minimizing.
set_icon_list() allows you to pass in the same icon in several hand-drawn sizes. The list should contain the natural sizes your icon is avilable in; that is, don't scale the image before passing it. Scaling is postponed until the last minute, when the desired final size is known, to allow best quality.
By passing several sizes, you may improve the final image quality of the icon, by reducing or eliminating automatic image scaling.
Recommended sizes to provide: 16x16, 32x32, 48x48 at minimum, and larger images (64x64, 128x128) if you have them.
- Methodset_icon_name
GTK2.Windowset_icon_name(stringname)- Description
Sets the icon for the window from a named themed icon.
- Methodset_mnemonic_modifier
GTK2.Windowset_mnemonic_modifier(intmodifier)- Description
Sets the mnemonic modifer for this window.
- Methodset_modal
GTK2.Windowset_modal(intsetting)- Description
Sets a window modal or non-modal. Modal windows prevent interaction with other windows in the same application. To keep modal dialogs on top of main application windows, use set_transient_for() to make the dialog transient for the parent; most window managers will then disallow lowering the dialog below the parent.
- Methodset_opacity
GTK2.Windowset_opacity(floatopacity)- Description
Request the windowing system to make this window partially transparent, with opacity 0 being full transparent and 1 fully opaque.
- Methodset_position
GTK2.Windowset_position(intpos)- Description
Sets a position contraint for this window. If the old or new constraint is GTK2.WIN_POS_CENTER_ALWAYS, this will also cause the window to be repositioned to satisfy the new constraint.
- Methodset_resizable
GTK2.Windowset_resizable(intsetting)- Description
Sets whether the user can resize a window. Windows are user resizable by default.
- Methodset_skip_pager_hint
GTK2.Windowset_skip_pager_hint(intsetting)- Description
Windows may set a hint asking the desktop environment not to display the window in the pager.
- Methodset_skip_taskbar_hint
GTK2.Windowset_skip_taskbar_hint(intsetting)- Description
Windows may set a hint asking the desktop environment not to display the window in the task bar. This function sets this hint.
- Methodset_startup_id
GTK2.Windowset_startup_id(stringid)- Description
Startup notification identifiers are used by desktop environment to track application startup, to provide user feedback and other features. This function changes the corresponding property on the underlying GDK2.Window.

- Description
Pango Font Description.
- Methodbetter_match
intbetter_match(GTK2.Pango.FontDescriptionnew,GTK2.Pango.FontDescriptionold)- Description
Determines if the style attributes of new are a closer match than old, or if old is omitted, determines if new is a match at all. Approximate matching is done for weight and style; other attributes must match exactly.
- Methodcreate
GTK2.Pango.FontDescriptionGTK2.Pango.FontDescription(string|voiddesc)- Description
Create a new font description. If desc is present, creates a new font description from a string representation in the form "[FAMILY-LIST] [STYLE-OPTIONS] [SIZE]", where FAMILY-LIST is a comma separated list of families optionally terminated by a comma, STYLE-OPTIONS is a whitespace separated list of words where each word describes one of style, variant, weight, or stretch, and size is a decimal number (size in points). Any one of the options may be absent. If FAMILY-LIST is absent, then the family name will be blank. If STYLE-OPTIONS is missing, then all style options will be set to the default values.

Sets the family name. The family name represents a family of related fonts styles, and will resolve to a particular PangoFontFamily.
- Methodset_size
Pango.FontDescriptionset_size(intsize)- Description
Sets the size in fractional points. This is the size of the font in points, scaled by PANGO_SCALE. (That is, a size value of 10*PANGO_SCALE) is a 10 point font. The conversion factor between points and device units depends on system configuration and the output device. For screen display, a logical DPI of 96 is common, in which case a 10 point font corresponds to a 1o*(96.72) = 13.3 pixel font. Use set_absolute_size() if you need a particular size in device units.
- Methodset_stretch
Pango.FontDescriptionset_stretch(intstretch)- Description
Sets the stretch. This specifies how narrow or wide the font should be. One of
PANGO_STRETCH_CONDENSED,PANGO_STRETCH_EXPANDED,PANGO_STRETCH_EXTRA_CONDENSED,PANGO_STRETCH_EXTRA_EXPANDED,PANGO_STRETCH_NORMAL,PANGO_STRETCH_SEMI_CONDENSED,PANGO_STRETCH_SEMI_EXPANDED,PANGO_STRETCH_ULTRA_CONDENSEDandPANGO_STRETCH_ULTRA_EXPANDED.

Pango.FontDescriptionset_style(intstyle)- Description
Sets the style. This describes whether the font is slanted and the manner in which is is slanted. One of
PANGO_STYLE_ITALIC,PANGO_STYLE_NORMALandPANGO_STYLE_OBLIQUE. Most fonts will either have an italic style or an oblique style, but not both, and font matching in Pango will match italic specifications with oblique fonts and vice-versa if an exact match is not found.
- Methodset_variant
Pango.FontDescriptionset_variant(intvariant)- Description
Sets the variant. One of
PANGO_VARIANT_NORMALandPANGO_VARIANT_SMALL_CAPS.
- Methodset_weight
Pango.FontDescriptionset_weight(intweight)- Description

Class GTK2.Pango.Layout
- Description
Pango Layout.
- Methodcontext_changed
Pango.Layoutcontext_changed()- Description
Forces recomputation of any state in the layout that might depend on the layout's context. This function should be called if you make changes to the context subsequent to creating the layout.
- Methodcreate
GTK2.Pango.LayoutGTK2.Pango.Layout(GTK2.Pango.Contextcontext)- Description
Create a new layout with attributes initialized to default values for a particular Pango.Context
- Methodget_auto_dir
intget_auto_dir()- Description
Gets whether to calculate the bidirectional base direction for the layout according to the contents of the layout.
- Methodget_cursor_pos
arrayget_cursor_pos(intindex)- Description
Given an index within a layout, determines the positions of the strong and weak cursors if the insertion point is at that index. The position of each cursor is stored as a zero-width rectangle. The strong cursor is the location where characters of the directionality equal to the base direction of the layout are inserted. The weak cursor location is the location where characters of the directionality opposite to the base direction of the layout are inserted. Returns: array of mappings, each mapping is the same as index_to_pos().
- Methodget_indent
intget_indent()- Description
Gets the paragraph indent in pango units. A negative value indicates a hanging indent.

intget_single_paragraph_mode()- Description
Gets the value set by set_single_paragraph_mode().
- Methodget_tabs
GTK2.Pango.TabArrayget_tabs()- Description

- Methodindex_to_pos
mappingindex_to_pos(intindex)- Description
Converts from an index to the onscreen position corresponding to the grapheme at that index, which is represented as a rectangle. Note that x is always the leading edge of the grapheme and x+width the trailing edge of the grapheme. If the direction of the grapheme is right-to-left, then width will be negative.
Returns: ([ "x": x coordinate, "y": y coordinate, "width": width of the rectangle, "height": height of the rectangle ])
- Methodmove_cursor_visually
mappingmove_cursor_visually(intstrong,intold_index,intold_trailing,intdir)- Description
Computes a new cursor position from an old position and a count of positions to move visually. If count is positive, then the new strong cursor position will be one position to the right of the old cursor position. If count is negative, then the new strong cursor position will be one position to the left of the old cursor position.
In the presence of bidirectional text, the correspondence between logical and visual order will depend on the direction of the current run, and there may be jumps when the cursor is moved off the end of a run.
Motion here is in cursor positions, not in characters, so a single call to move_cursor_visually() may move the cursor over multiple characters when multiple characters combine to form a single grapheme.
- Methodset_alignment
Pango.Layoutset_alignment(intalignment)- Description
Sets the alignment for the layout (how partial lines are positioned within the horizontal space available.) One of
PANGO_ALIGN_CENTER,PANGO_ALIGN_LEFTandPANGO_ALIGN_RIGHT.
- Methodset_auto_dir
Pango.Layoutset_auto_dir(intauto_dir)- Description
Sets whether to calculate the bidirectional base direction for the layout according to the contents of the layout; when this flag is on (the default), then paragraphs that begin with strong right-to-left characters (Arabic and Hebrew principally), will have right-left-layout, paragraphs with letters from other scripts will have left-to-right layout. Paragraphs with only neutral characters get their direction from the surrounding paragraphs.
When false, the choice between left-to-right and right-to-left layout is done by according to the base direction of the Pango.Context.
- Methodset_font_description
Pango.Layoutset_font_description(GTK2.Pango.FontDescriptiondesc)- Description
Sets the default font description for the layout. If no font description is set on the layout, the font descriptions from the layout's context is used.
- Methodset_indent
Pango.Layoutset_indent(intindent)- Description
Sets the width in pango units to indent each paragraph. A negative value of indent will produce a hanging indent. That is, the first line will have the full width, and subsequent lines will be indented by the absolute value of indent.
- Methodset_justify
Pango.Layoutset_justify(intjustify)- Description
Sets whether or not each complete line should be stretched to fill the entire width of the layout. This stretching is typically done by adding whitespace, but for some scripts (such as Arabic), the justification is done by extending the characters.
- Methodset_markup
Pango.Layoutset_markup(stringmarkup,intlength)- Description
Same as set_markup_with_accel(), but the markup text isn't scanned for accelerators.
- Methodset_markup_with_accel
Pango.Layoutset_markup_with_accel(stringmarkup,intlength,int|voidaccel_marker)- Description
Sets the layout text and attribute from marked-up text. Replaces the current text and attribute list.
If accel_marker is nonzero, the given character will mark the character following it as an accelerator. For example, the accel marker might be an ampersand or underscore. All characters marked as an acclerator will receive a GTK2.PANGO_UNDERLINE_LOW attribute, and the first character so marked will be returned. Two accel_marker characters following each other produce a single literal accel_marker character.
- Methodset_single_paragraph_mode
Pango.Layoutset_single_paragraph_mode(intsetting)- Description
If setting is true, do not treat newlines and similar characters as paragraph separators; instead, keep all text in a single paragraph, and display a glyph for paragraph separator characters. Used when you want to allow editing of newlines on a single text line.
- Methodset_spacing
Pango.Layoutset_spacing(intspacing)- Description
Sets the amount of spacing between the lines.
- Methodset_tabs
Pango.Layoutset_tabs(GTK2.Pango.TabArraytabs)- Description

- Methodset_text
Pango.Layoutset_text(sprintf_formattext,sprintf_args...fmt)- Description
Sets the text of the layout.
- Methodset_width
Pango.Layoutset_width(intwidth)- Description
Sets the width to which the lines should be wrapped.
- Methodset_wrap
Pango.Layoutset_wrap(intwrap)- Description
Sets the wrap mode; the wrap mode only has an effect if a width is set on the layout with set_width(). To turn off wrapping, set the width to -1. One of
PANGO_WRAP_CHAR,PANGO_WRAP_WORDandPANGO_WRAP_WORD_CHAR.
- Methodxy_to_index
mappingxy_to_index(intx,inty)- Description
Converts from x and y position within a layout to the byte index to the character at that logical position. If the y position is not inside the layout, the closest position is chosen (the position will be clamped inside the layout). If the X position is not within the layout, then the start or the end of the line is chosen as describe for x_to_index(). If either the x or y positions were not inside the layout, then returns 0.
Returns: ([ "index": byte index, "trailing": where in grapheme user clicked ]).
Class GTK2.Pango.LayoutIter

- Methodget_char_extents
mappingget_char_extents()- Description
Gets the extents of the current character, in layout coordinates (origin is the top left of the entire layout).
- Methodget_cluster_extents
arrayget_cluster_extents()- Description
Gets the extents of the current cluster, in layout coordinates.
- Methodget_index
intget_index()- Description
Gets the current byte index. Note that iterating forward by char moves in visual order, not logical order, so indexes may not be sequential. Also, the index may be equal to the length of the text in the layout.
- Methodget_line_yrange
arrayget_line_yrange()- Description
Divides the vertical space being iterated over between the lines in the layout, and returns the space belonging to the current line. A line's range includes the line's logical extents, plus half of the spacing above and below the line, if Pango.Layout->set_spacing() has been called to set layout spacing. The y positions are in layout coordinates.
- Methodget_run_extents
arrayget_run_extents()- Description
Gets the extents of the current run in layout coordinates.
- Methodnext_char
intnext_char()- Description
Moves forward to the next character in visual order. If it was already at the end of the layout, returns false.

Converts an index within a line to an x position.
- Methodx_to_index
mappingx_to_index(intx_pos)- Description
Converts from x offset to the byte index of the corresponding character within the text of the layout. If x_pos is outside the line, index and trailing will point to the very first or very last position in the line. This determination is based on the resolved direction of the paragraph; for example, if the resolved direction is right-to-left, then an X position to the right of the line (after it) results in 0 being stored in index and trailing. An X position to the left of the line results in index pointing to the (logical) last grapheme in the line and trailing set to the number of characters in that grapheme. The reverse is true for a left-to-right line.
Class GTK2.Pango.TabArray
- Description
A set of tab stops for laying out text that includes tab characters.
- Methodcreate
GTK2.Pango.TabArrayGTK2.Pango.TabArray(intinitial_size,intposition_in_pixels)- Description
