Details

Gtk.accel_groups_activate(object, accel_key, accel_mods)[source]

Parameters:

Returns:

True if an accelerator was activated and handled this keypress

Return type:

bool

Finds the first accelerator in any Gtk.AccelGroup attached to object that matches accel_key and accel_mods, and activates that accelerator.

Gtk.accel_groups_from_object(object)[source]

Parameters:

object (GObject.Object) – a GObject.Object, usually a Gtk.Window

Returns:

a list of all accel groups which are attached to object

Return type:

[Gtk.AccelGroup]

Gets a list of all accel groups which are attached to object.

Gtk.accelerator_get_default_mod_mask()[source]

Returns:

the default accelerator modifier mask

Return type:

Gdk.ModifierType

Gets the modifier mask.

The modifier mask determines which modifiers are considered significant for keyboard accelerators. See Gtk.accelerator_set_default_mod_mask().

Gtk.accelerator_get_label(accelerator_key, accelerator_mods)[source]

Parameters:

Returns:

a newly-allocated string representing the accelerator.

Return type:

str

Converts an accelerator keyval and modifier mask into a string which can be used to represent the accelerator to the user.

New in version 2.6.

Gtk.accelerator_get_label_with_keycode(display, accelerator_key, keycode, accelerator_mods)[source]

Parameters:

Returns:

a newly-allocated string representing the accelerator.

Return type:

str

Converts an accelerator keyval and modifier mask into a (possibly translated) string that can be displayed to a user, similarly to Gtk.accelerator_get_label(), but handling keycodes.

This is only useful for system-level components, applications should use Gtk.accelerator_parse() instead.

New in version 3.4.

Gtk.accelerator_name(accelerator_key, accelerator_mods)[source]

Parameters:

Returns:

a newly-allocated accelerator name

Return type:

str

Converts an accelerator keyval and modifier mask into a string parseable by Gtk.accelerator_parse(). For example, if you pass inGdk.KEY_q and Gdk.ModifierType.CONTROL_MASK, this function returns “q”.

If you need to display accelerators in the user interface, see Gtk.accelerator_get_label().

Gtk.accelerator_name_with_keycode(display, accelerator_key, keycode, accelerator_mods)[source]

Parameters:

Returns:

a newly allocated accelerator name.

Return type:

str

Converts an accelerator keyval and modifier mask into a string parseable by Gtk.accelerator_parse_with_keycode(), similarly to Gtk.accelerator_name() but handling keycodes. This is only useful for system-level components, applications should use Gtk.accelerator_parse() instead.

New in version 3.4.

Gtk.accelerator_parse(accelerator)[source]

Parameters:

accelerator (str) – string representing an accelerator

Returns:

accelerator_key:

return location for accelerator keyval, or None

accelerator_mods:

return location for accelerator modifier mask, None

Return type:

(accelerator_key: int, accelerator_mods: Gdk.ModifierType)

Parses a string representing an accelerator. The format looks like<Control>a or <Shift><Alt>F1 or <Release>z (the last one is for key release).

The parser is fairly liberal and allows lower or upper case, and also abbreviations such as <Ctl> and <Ctrl>. Key names are parsed usingGdk.keyval_from_name(). For character keys the name is not the symbol, but the lowercase name, e.g. one would use <Ctrl>minus instead of<Ctrl>-.

If the parse fails, accelerator_key and accelerator_mods will be set to 0 (zero).

Gtk.accelerator_parse_with_keycode(accelerator)[source]

Parameters:

accelerator (str) – string representing an accelerator

Returns:

accelerator_key:

return location for accelerator keyval, or None

accelerator_codes:

return location for accelerator keycodes, or None

accelerator_mods:

return location for accelerator modifier mask, None

Return type:

(accelerator_key: int, accelerator_codes: [int], accelerator_mods: Gdk.ModifierType)

Parses a string representing an accelerator, similarly toGtk.accelerator_parse() but handles keycodes as well. This is only useful for system-level components, applications should useGtk.accelerator_parse() instead.

If accelerator_codes is given and the result stored in it is non-None, the result must be freed with GLib.free().

If a keycode is present in the accelerator and no accelerator_codesis given, the parse will fail.

If the parse fails, accelerator_key, accelerator_mods andaccelerator_codes will be set to 0 (zero).

New in version 3.4.

Gtk.accelerator_set_default_mod_mask(default_mod_mask)[source]

Parameters:

default_mod_mask (Gdk.ModifierType) – accelerator modifier mask

Sets the modifiers that will be considered significant for keyboard accelerators. The default mod mask depends on the GDK backend in use, but will typically include Gdk.ModifierType.CONTROL_MASK | Gdk.ModifierType.SHIFT_MASK |Gdk.ModifierType.MOD1_MASK | Gdk.ModifierType.SUPER_MASK | Gdk.ModifierType.HYPER_MASK | Gdk.ModifierType.META_MASK. In other words, Control, Shift, Alt, Super, Hyper and Meta. Other modifiers will by default be ignored by Gtk.AccelGroup.

You must include at least the three modifiers Control, Shift and Alt in any value you pass to this function.

The default mod mask should be changed on application startup, before using any accelerator groups.

Gtk.accelerator_valid(keyval, modifiers)[source]

Parameters:

Returns:

True if the accelerator is valid

Return type:

bool

Determines whether a given keyval and modifier mask constitute a valid keyboard accelerator. For example, the Gdk.KEY_a keyval plus Gdk.ModifierType.CONTROL_MASK is valid - this is a “Ctrl+a” accelerator. But, you can’t, for instance, use the Gdk.KEY_Control_L keyval as an accelerator.

Gtk.alternative_dialog_button_order(screen)[source]

Parameters:

screen (Gdk.Screen or None) – a Gdk.Screen, or None to use the default screen

Returns:

Whether the alternative button order should be used

Return type:

bool

Returns True if dialogs are expected to use an alternative button order on the screen screen. See gtk_dialog_set_alternative_button_order() for more details about alternative button order.

If you need to use this function, you should probably connect to the ::notify:gtk-alternative-button-order signal on theGtk.Settings object associated to screen, in order to be notified if the button order setting changes.

New in version 2.6.

Deprecated since version 3.10: Deprecated

Gtk.binding_entry_add_signal_from_string(binding_set, signal_desc)[source]

Parameters:

Returns:

GLib.TokenType.NONE if the signal was successfully parsed and added, the expected token otherwise

Return type:

GLib.TokenType

Parses a signal description from signal_desc and incorporates it into binding_set.

Signal descriptions may either bind a key combination to one or more signals:

bind "key" { "signalname" (param, ...) ... }

Or they may also unbind a key combination:

unbind "key"

Key combinations must be in a format that can be parsed byGtk.accelerator_parse().

New in version 3.0.

Gtk.binding_entry_add_signall(binding_set, keyval, modifiers, signal_name, binding_args)[source]

Parameters:

Override or install a new key binding for keyval with modifiers onbinding_set.

Gtk.binding_entry_remove(binding_set, keyval, modifiers)[source]

Parameters:

Remove a binding previously installed via gtk_binding_entry_add_signal() on binding_set.

Gtk.binding_entry_skip(binding_set, keyval, modifiers)[source]

Parameters:

Install a binding on binding_set which causes key lookups to be aborted, to prevent bindings from lower priority sets to be activated.

New in version 2.12.

Gtk.binding_set_find(set_name)[source]

Parameters:

set_name (str) – unique binding set name

Returns:

None or the specified binding set

Return type:

Gtk.BindingSet or None

Find a binding set by its globally unique name.

The set_name can either be a name used for gtk_binding_set_new() or the type name of a class used in gtk_binding_set_by_class().

Gtk.bindings_activate(object, keyval, modifiers)[source]

Parameters:

Returns:

True if a binding was found and activated

Return type:

bool

Find a key binding matching keyval and modifiers and activate the binding on object.

Gtk.bindings_activate_event(object, event)[source]

Parameters:

Returns:

True if a matching key binding was found

Return type:

bool

Looks up key bindings for object to find one matchingevent, and if one was found, activate it.

New in version 2.4.

Gtk.builder_error_quark()[source]

Return type:

int

Gtk.cairo_should_draw_window(cr, window)[source]

Parameters:

Returns:

True if window should be drawn

Return type:

bool

This function is supposed to be called in Gtk.Widget ::drawimplementations for widgets that support multiple windows.cr must be untransformed from invoking of the draw function. This function will return True if the contents of the givenwindow are supposed to be drawn and False otherwise. Note that when the drawing was not initiated by the windowing system this function will return True for all windows, so you need to draw the bottommost window first. Also, do not use “else if” statements to check which window should be drawn.

New in version 3.0.

Gtk.cairo_transform_to_window(cr, widget, window)[source]

Parameters:

Transforms the given cairo context cr that from widget-relative coordinates to window-relative coordinates. If the widget’s window is not an ancestor of window, no modification will be applied.

This is the inverse to the transformation GTK applies when preparing an expose event to be emitted with the Gtk.Widget ::drawsignal. It is intended to help porting multiwindow widgets from GTK+ 2 to the rendering architecture of GTK+ 3.

New in version 3.0.

Gtk.check_version(required_major, required_minor, required_micro)[source]

Parameters:

Returns:

None if the GTK+ library is compatible with the given version, or a string describing the version mismatch. The returned string is owned by GTK+ and should not be modified or freed.

Return type:

str or None

Checks that the GTK+ library in use is compatible with the given version. Generally you would pass in the constantsGtk.MAJOR_VERSION, Gtk.MINOR_VERSION, Gtk.MICRO_VERSIONas the three arguments to this function; that produces a check that the library in use is compatible with the version of GTK+ the application or module was compiled against.

Compatibility is defined by two things: first the version of the running library is newer than the versionrequired_major.required_minor.`required_micro`. Second the running library must be binary compatible with the version required_major.required_minor.`required_micro` (same major version.)

This function is primarily for GTK+ modules; the module can call this function to check that it wasn’t loaded into an incompatible version of GTK+. However, such a check isn’t completely reliable, since the module may be linked against an old version of GTK+ and calling the old version of Gtk.check_version(), but still get loaded into an application using a newer version of GTK+.

Gtk.css_provider_error_quark()[source]

Return type:

int

Gtk.device_grab_add(widget, device, block_others)[source]

Parameters:

Adds a GTK+ grab on device, so all the events on device and its associated pointer or keyboard (if any) are delivered to widget. If the block_others parameter is True, any other devices will be unable to interact with widget during the grab.

New in version 3.0.

Gtk.device_grab_remove(widget, device)[source]

Parameters:

Removes a device grab from the given widget.

You have to pair calls to Gtk.device_grab_add() andGtk.device_grab_remove().

New in version 3.0.

Gtk.disable_setlocale()[source]

Prevents Gtk.init(), Gtk.init_check(), Gtk.init_with_args() andGtk.parse_args() from automatically calling setlocale (LC_ALL, ""). You would want to use this function if you wanted to set the locale for your program to something other than the user’s locale, or if you wanted to set different values for different locale categories.

Most programs should not need to call this function.

Gtk.distribute_natural_allocation(extra_space, n_requested_sizes, sizes)[source]

Parameters:

Returns:

The remainder of extra_space after redistributing space to sizes.

Return type:

int

Distributes extra_space to child sizes by bringing smaller children up to natural size first.

The remaining space will be added to the minimum_size member of theGtk.RequestedSize struct. If all sizes reach their natural size then the remaining space is returned.

Gtk.drag_cancel(context)[source]

Parameters:

context (Gdk.DragContext) – a Gdk.DragContext, as e.g. returned by Gtk.Widget.drag_begin_with_coordinates()

Cancels an ongoing drag operation on the source side.

If you want to be able to cancel a drag operation in this way, you need to keep a pointer to the drag context, either from an explicit call to Gtk.Widget.drag_begin_with_coordinates(), or by connecting to Gtk.Widget ::drag-begin.

If context does not refer to an ongoing drag operation, this function does nothing.

If a drag is cancelled in this way, the result argument ofGtk.Widget ::drag-failed is set to Gtk.DragResult.ERROR.

New in version 3.16.

Gtk.drag_finish(context, success, del_, time_)[source]

Parameters:

Informs the drag source that the drop is finished, and that the data of the drag will no longer be required.

Gtk.drag_get_source_widget(context)[source]

Parameters:

context (Gdk.DragContext) – a (destination side) drag context

Returns:

if the drag is occurring within a single application, a pointer to the source widget. Otherwise, None.

Return type:

Gtk.Widget or None

Determines the source widget for a drag.

Gtk.drag_set_icon_default(context)[source]

Parameters:

context (Gdk.DragContext) – the context for a drag (This must be called with a context for the source side of a drag)

Sets the icon for a particular drag to the default icon.

Gtk.drag_set_icon_gicon(context, icon, hot_x, hot_y)[source]

Parameters:

Sets the icon for a given drag from the given icon. See the documentation for Gtk.drag_set_icon_name() for more details about using icons in drag and drop.

New in version 3.2.

Gtk.drag_set_icon_name(context, icon_name, hot_x, hot_y)[source]

Parameters:

Sets the icon for a given drag from a named themed icon. See the docs for Gtk.IconTheme for more details. Note that the size of the icon depends on the icon theme (the icon is loaded at the symbolic size Gtk.IconSize.DND), thushot_x and hot_y have to be used with care.

New in version 2.8.

Gtk.drag_set_icon_pixbuf(context, pixbuf, hot_x, hot_y)[source]

Parameters:

Sets pixbuf as the icon for a given drag.

Gtk.drag_set_icon_stock(context, stock_id, hot_x, hot_y)[source]

Parameters:

Sets the icon for a given drag from a stock ID.

Deprecated since version 3.10: Use Gtk.drag_set_icon_name() instead.

Gtk.drag_set_icon_surface(context, surface)[source]

Parameters:

Sets surface as the icon for a given drag. GTK+ retains references for the arguments, and will release them when they are no longer needed.

To position the surface relative to the mouse, usecairo.Surface.set_device_offset() on surface. The mouse cursor will be positioned at the (0,0) coordinate of the surface.

Gtk.drag_set_icon_widget(context, widget, hot_x, hot_y)[source]

Parameters:

Changes the icon for drag operation to a given widget. GTK+ will not destroy the widget, so if you don’t want it to persist, you should connect to the “drag-end” signal and destroy it yourself.

Gtk.draw_insertion_cursor(widget, cr, location, is_primary, direction, draw_arrow)[source]

Parameters:

Draws a text caret on cr at location. This is not a style function but merely a convenience function for drawing the standard cursor shape.

New in version 3.0.

Deprecated since version 3.4: Use Gtk.render_insertion_cursor() instead.

Gtk.events_pending()[source]

Returns:

True if any events are pending, False otherwise

Return type:

bool

Checks if any events are pending.

This can be used to update the UI and invoke timeouts etc. while doing some time intensive computation.

Updating the UI during a long computation

// computation going on...

while (gtk_events_pending ()) gtk_main_iteration ();

// ...computation continued

Gtk.false()[source]

Returns:

False

Return type:

bool

Analogical to Gtk.true(), this function does nothing but always returns False.

Gtk.file_chooser_error_quark()[source]

Returns:

The error quark used for Gtk.FileChooser errors.

Return type:

int

Registers an error quark for Gtk.FileChooser if necessary.

New in version 2.4.

Gtk.get_binary_age()[source]

Returns:

the binary age of the GTK+ library

Return type:

int

Returns the binary age as passed to libtoolwhen building the GTK+ library the process is running against. If libtool means nothing to you, don’t worry about it.

New in version 3.0.

Gtk.get_current_event()[source]

Returns:

a copy of the current event, orNone if there is no current event. The returned event must be freed with Gdk.Event.free().

Return type:

Gdk.Event or None

Obtains a copy of the event currently being processed by GTK+.

For example, if you are handling a Gtk.Button ::clicked signal, the current event will be the Gdk.EventButton that triggered the ::clicked signal.

Gtk.get_current_event_device()[source]

Returns:

a Gdk.Device, or None

Return type:

Gdk.Device or None

If there is a current event and it has a device, return that device, otherwise return None.

Gtk.get_current_event_state()[source]

Returns:

True if there was a current event and it had a state field

state:

a location to store the state of the current event

Return type:

(bool, state: Gdk.ModifierType)

If there is a current event and it has a state field, place that state field in state and return True, otherwise returnFalse.

Gtk.get_current_event_time()[source]

Returns:

the timestamp from the current event, or Gdk.CURRENT_TIME.

Return type:

int

If there is a current event and it has a timestamp, return that timestamp, otherwise return Gdk.CURRENT_TIME.

Gtk.get_debug_flags()[source]

Returns:

the GTK+ debug flags.

Return type:

int

Returns the GTK+ debug flags.

This function is intended for GTK+ modules that want to adjust their debug output based on GTK+ debug flags.

Gtk.get_default_language()[source]

Returns:

the default language as a Pango.Language, must not be freed

Return type:

Pango.Language

Returns the Pango.Language for the default language currently in effect. (Note that this can change over the life of an application.) The default language is derived from the current locale. It determines, for example, whether GTK+ uses the right-to-left or left-to-right text direction.

This function is equivalent to Pango.Language.get_default(). See that function for details.

Gtk.get_event_widget(event)[source]

Parameters:

event (Gdk.Event) – a Gdk.Event

Returns:

the widget that originally received event, or None

Return type:

Gtk.Widget or None

If event is None or the event was not associated with any widget, returns None, otherwise returns the widget that received the event originally.

Gtk.get_interface_age()[source]

Returns:

the interface age of the GTK+ library

Return type:

int

Returns the interface age as passed to libtoolwhen building the GTK+ library the process is running against. If libtool means nothing to you, don’t worry about it.

New in version 3.0.

Gtk.get_locale_direction()[source]

Returns:

the Gtk.TextDirection of the current locale

Return type:

Gtk.TextDirection

Get the direction of the current locale. This is the expected reading direction for text and UI.

This function depends on the current locale being set with setlocale() and will default to setting the Gtk.TextDirection.LTRdirection otherwise. Gtk.TextDirection.NONE will never be returned.

GTK+ sets the default text direction according to the locale during Gtk.init(), and you should normally useGtk.Widget.get_direction() or Gtk.Widget.get_default_direction() to obtain the current direcion.

This function is only needed rare cases when the locale is changed after GTK+ has already been initialized. In this case, you can use it to update the default text direction as follows:

setlocale (LC_ALL, new_locale); direction = gtk_get_locale_direction (); gtk_widget_set_default_direction (direction);

New in version 3.12.

Gtk.get_major_version()[source]

Returns:

the major version number of the GTK+ library

Return type:

int

Returns the major version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 3.)

This function is in the library, so it represents the GTK+ library your code is running against. Contrast with the Gtk.MAJOR_VERSIONmacro, which represents the major version of the GTK+ headers you have included when compiling your code.

New in version 3.0.

Gtk.get_micro_version()[source]

Returns:

the micro version number of the GTK+ library

Return type:

int

Returns the micro version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 5.)

This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with theGtk.MICRO_VERSION macro, which represents the micro version of the GTK+ headers you have included when compiling your code.

New in version 3.0.

Gtk.get_minor_version()[source]

Returns:

the minor version number of the GTK+ library

Return type:

int

Returns the minor version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 1.)

This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with theGtk.MINOR_VERSION macro, which represents the minor version of the GTK+ headers you have included when compiling your code.

New in version 3.0.

Gtk.get_option_group(open_default_display)[source]

Parameters:

open_default_display (bool) – whether to open the default display when parsing the commandline arguments

Returns:

a GLib.OptionGroup for the commandline arguments recognized by GTK+

Return type:

GLib.OptionGroup

Returns a GLib.OptionGroup for the commandline arguments recognized by GTK+ and GDK.

You should add this group to your GLib.OptionContextwith GLib.OptionContext.add_group(), if you are usingGLib.OptionContext.parse() to parse your commandline arguments.

New in version 2.6.

Gtk.grab_get_current()[source]

Returns:

The widget which currently has the grab or None if no grab is active

Return type:

Gtk.Widget or None

Queries the current grab of the default window group.

Gtk.icon_size_from_name(name)[source]

Parameters:

name (str) – the name to look up.

Returns:

the icon size (Gtk.IconSize)

Return type:

int

Looks up the icon size associated with name.

Deprecated since version 3.10: Use Gtk.IconTheme instead.

Gtk.icon_size_get_name(size)[source]

Parameters:

size (int) – a Gtk.IconSize.

Returns:

the name of the given icon size.

Return type:

str

Gets the canonical name of the given icon size. The returned string is statically allocated and should not be freed.

Deprecated since version 3.10: Use Gtk.IconTheme instead.

Gtk.icon_size_lookup(size)[source]

Parameters:

size (int) – an icon size (Gtk.IconSize)

Returns:

True if size was a valid size

width:

location to store icon width

height:

location to store icon height

Return type:

(bool, width: int, height: int)

Obtains the pixel size of a semantic icon size size:Gtk.IconSize.MENU, Gtk.IconSize.BUTTON, etc. This function isn’t normally needed, Gtk.IconTheme.load_icon() is the usual way to get an icon for rendering, then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by Gtk.IconSize.lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

Gtk.icon_size_lookup_for_settings(settings, size)[source]

Parameters:

Returns:

True if size was a valid size

width:

location to store icon width

height:

location to store icon height

Return type:

(bool, width: int, height: int)

Obtains the pixel size of a semantic icon size, possibly modified by user preferences for a particularGtk.Settings. Normally size would beGtk.IconSize.MENU, Gtk.IconSize.BUTTON, etc. This function isn’t normally needed, Gtk.Widget.render_icon_pixbuf() is the usual way to get an icon for rendering, then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by Gtk.IconSize.lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

New in version 2.2.

Gtk.icon_size_register(name, width, height)[source]

Parameters:

Returns:

integer value representing the size (Gtk.IconSize)

Return type:

int

Registers a new icon size, along the same lines as Gtk.IconSize.MENU, etc. Returns the integer value for the size.

Deprecated since version 3.10: Use Gtk.IconTheme instead.

Gtk.icon_size_register_alias(alias, target)[source]

Parameters:

Registers alias as another name for target. So calling Gtk.IconSize.from_name() with alias as argument will return target.

Deprecated since version 3.10: Use Gtk.IconTheme instead.

Gtk.icon_theme_error_quark()[source]

Return type:

int

Gtk.init(argv)[source]

Parameters:

argv ([str] or None) – Address of theargv parameter of main(), or None. Any options understood by GTK+ are stripped before return.

Returns:

Address of theargv parameter of main(), or None. Any options understood by GTK+ are stripped before return.

Return type:

argv: [str]

Call this function before using any other GTK+ functions in your GUI applications. It will initialize everything needed to operate the toolkit and parses some standard command line options.

Although you are expected to pass the argc, argv parameters from main() to this function, it is possible to pass None if argv is not available or commandline handling is not required.

argc and argv are adjusted accordingly so your own code will never see those standard arguments.

Note that there are some alternative ways to initialize GTK+: if you are calling Gtk.parse_args(), Gtk.init_check(),Gtk.init_with_args() or GLib.OptionContext.parse() with the option group returned by Gtk.get_option_group(), you don’t have to call Gtk.init().

And if you are using Gtk.Application, you don’t have to call any of the initialization functions either; the Gtk.Application ::startup handler does it for you.

This function will terminate your program if it was unable to initialize the windowing system for some reason. If you want your program to fall back to a textual interface you want to call Gtk.init_check() instead.

Since 2.18, GTK+ calls signal (SIGPIPE, SIG_IGN)during initialization, to ignore SIGPIPE signals, since these are almost never wanted in graphical applications. If you do need to handle SIGPIPE for some reason, reset the handler after Gtk.init(), but notice that other libraries (e.g. libdbus or gvfs) might do similar things.

Gtk.init_check(argv)[source]

Parameters:

argv ([str] or None) – Address of theargv parameter of main(), or None. Any options understood by GTK+ are stripped before return.

Returns:

True if the commandline arguments (if any) were valid and the windowing system has been successfully initialized, Falseotherwise

argv:

Address of theargv parameter of main(), or None. Any options understood by GTK+ are stripped before return.

Return type:

(bool, argv: [str])

This function does the same work as Gtk.init() with only a single change: It does not terminate the program if the commandline arguments couldn’t be parsed or the windowing system can’t be initialized. Instead it returns False on failure.

This way the application can fall back to some other means of communication with the user - for example a curses or command line interface.

Note that calling any GTK function or instantiating any GTK type after this function returns False results in undefined behavior.

Gtk.init_with_args(argv, parameter_string, entries, translation_domain)[source]

Parameters:

Raises:

GLib.Error

Returns:

True if the commandline arguments (if any) were valid and if the windowing system has been successfully initialized,False otherwise

argv:

Address of theargv parameter of main(), or None. Any options understood by GTK+ are stripped before return.

Return type:

(bool, argv: [str])

This function does the same work as Gtk.init_check(). Additionally, it allows you to add your own commandline options, and it automatically generates nicely formatted--help output. Note that your program will be terminated after writing out the help output.

New in version 2.6.

Gtk.key_snooper_remove(snooper_handler_id)[source]

Parameters:

snooper_handler_id (int) – Identifies the key snooper to remove

Removes the key snooper function with the given id.

Deprecated since version 3.4: Key snooping should not be done. Events should be handled by widgets.

Gtk.main()[source]

Runs the main loop until Gtk.main_quit() is called.

You can nest calls to Gtk.main(). In that case Gtk.main_quit() will make the innermost invocation of the main loop return.

Gtk.main_do_event(event)[source]

Parameters:

event (Gdk.Event) – An event to process (normally passed by GDK)

Processes a single GDK event.

This is public only to allow filtering of events between GDK and GTK+. You will not usually need to call this function directly.

While you should not call this function directly, you might want to know how exactly events are handled. So here is what this function does with the event:

Compress enter/leave notify events. If the event passed build an enter/leave pair together with the next event (peeked from GDK), both events are thrown away. This is to avoid a backlog of (de-)highlighting widgets crossed by the pointer.

Find the widget which got the event. If the widget can’t be determined the event is thrown away unless it belongs to a INCR transaction.

Then the event is pushed onto a stack so you can query the currently handled event with Gtk.get_current_event().

The event is sent to a widget. If a grab is active all events for widgets that are not in the contained in the grab widget are sent to the latter with a few exceptions:

After finishing the delivery the event is popped from the event stack.

Gtk.main_iteration()[source]

Returns:

True if Gtk.main_quit() has been called for the innermost mainloop

Return type:

bool

Runs a single iteration of the mainloop.

If no events are waiting to be processed GTK+ will block until the next event is noticed. If you don’t want to block look at Gtk.main_iteration_do() or check if any events are pending with Gtk.events_pending() first.

Gtk.main_iteration_do(blocking)[source]

Parameters:

blocking (bool) – True if you want GTK+ to block if no events are pending

Returns:

True if Gtk.main_quit() has been called for the innermost mainloop

Return type:

bool

Runs a single iteration of the mainloop. If no events are available either return or block depending on the value of blocking.

Gtk.main_level()[source]

Returns:

the nesting level of the current invocation of the main loop

Return type:

int

Asks for the current nesting level of the main loop.

Gtk.main_quit()[source]

Makes the innermost invocation of the main loop return when it regains control.

Gtk.paint_arrow(style, cr, state_type, shadow_type, widget, detail, arrow_type, fill, x, y, width, height)[source]

Deprecated since version 3.0: Use cairo instead

Gtk.paint_expander(style, cr, state_type, widget, detail, x, y, expander_style)[source]

Parameters:

Draws an expander as used in Gtk.TreeView. x and y specify the center the expander. The size of the expander is determined by the “expander-size” style property of widget. (If widget is not specified or doesn’t have an “expander-size” property, an unspecified default size will be used, since the caller doesn’t have sufficient information to position the expander, this is likely not useful.) The expander is expander_size pixels tall in the collapsed position and expander_size pixels wide in the expanded position.

Deprecated since version 3.0: Use Gtk.render_expander() instead

Gtk.paint_extension(style, cr, state_type, shadow_type, widget, detail, x, y, width, height, gap_side)[source]

Return type:

str

Returns the name of the default paper size, which depends on the current locale.

New in version 2.10.

Gtk.paper_size_get_paper_sizes(include_custom)[source]

Parameters:

include_custom (bool) – whether to include custom paper sizes as defined in the page setup dialog

Returns:

a newly allocated list of newly allocated Gtk.PaperSize objects

Return type:

Creates a list of known paper sizes.

New in version 2.12.

Gtk.parse_args(argv)[source]

Parameters:

argv ([str]) – a pointer to the array of command line arguments

Returns:

True if initialization succeeded, otherwise False

argv:

a pointer to the array of command line arguments

Return type:

(bool, argv: [str])

Parses command line arguments, and initializes global attributes of GTK+, but does not actually open a connection to a display. (See Gdk.Display.open(), Gdk.get_display_arg_name())

Any arguments used by GTK+ or GDK are removed from the array andargc and argv are updated accordingly.

There is no need to call this function explicitly if you are usingGtk.init(), or Gtk.init_check().

Note that many aspects of GTK+ require a display connection to function, so this way of initializing GTK+ is really only useful for specialized use cases.

Gtk.print_error_quark()[source]

Returns:

The error quark used for Gtk.PrintOperation errors.

Return type:

int

Registers an error quark for Gtk.PrintOperation if necessary.

New in version 2.10.

Gtk.print_run_page_setup_dialog(parent, page_setup, settings)[source]

Parameters:

Returns:

a new Gtk.PageSetup

Return type:

Gtk.PageSetup

Runs a page setup dialog, letting the user modify the values frompage_setup. If the user cancels the dialog, the returned Gtk.PageSetupis identical to the passed in page_setup, otherwise it contains the modifications done in the dialog.

Note that this function may use a recursive mainloop to show the page setup dialog. See Gtk.print_run_page_setup_dialog_async() if this is a problem.

New in version 2.10.

Gtk.print_run_page_setup_dialog_async(parent, page_setup, settings, done_cb, *data)[source]

Parameters:

Runs a page setup dialog, letting the user modify the values from page_setup.

In contrast to Gtk.print_run_page_setup_dialog(), this function returns after showing the page setup dialog on platforms that support this, and calls done_cbfrom a signal handler for the ::response signal of the dialog.

New in version 2.10.

Gtk.propagate_event(widget, event)[source]

Parameters:

Sends an event to a widget, propagating the event to parent widgets if the event remains unhandled.

Events received by GTK+ from GDK normally begin in Gtk.main_do_event(). Depending on the type of event, existence of modal dialogs, grabs, etc., the event may be propagated; if so, this function is used.

Gtk.propagate_event() calls Gtk.Widget.event() on each widget it decides to send the event to. So Gtk.Widget.event() is the lowest-level function; it simply emits the Gtk.Widget ::event and possibly an event-specific signal on a widget. Gtk.propagate_event() is a bit higher-level, and Gtk.main_do_event() is the highest level.

All that said, you most likely don’t want to use any of these functions; synthesizing events is rarely needed. There are almost certainly better ways to achieve your goals. For example, useGdk.Window.invalidate_rect() or Gtk.Widget.queue_draw() instead of making up expose events.

Gtk.rc_add_default_file(filename)[source]

Parameters:

filename (str) – the pathname to the file. If filenameis not absolute, it is searched in the current directory.

Adds a file to the list of files to be parsed at the end of Gtk.init().

Gtk.rc_find_module_in_path(module_file)[source]

Parameters:

module_file (str) – name of a theme engine

Returns:

The filename, if found (must be freed with GLib.free()), otherwise None.

Return type:

str

Searches for a theme engine in the GTK+ search path. This function is not useful for applications and should not be used.

Gtk.rc_find_pixmap_in_path(settings, scanner, pixmap_file)[source]

Parameters:

Returns:

the filename.

Return type:

str

Looks up a file in pixmap path for the specified Gtk.Settings. If the file is not found, it outputs a warning message using g_warning() and returns None.

Gtk.rc_get_default_files()[source]

Returns:

A None-terminated array of filenames. This memory is owned by GTK+ and must not be freed by the application. If you want to store this information, you should make a copy.

Return type:

[str]

Retrieves the current list of RC files that will be parsed at the end of Gtk.init().

Gtk.rc_get_im_module_file()[source]

Returns:

a newly-allocated string containing the name of the file listing the IM modules available for loading

Return type:

str

Obtains the path to the IM modules file. See the documentation of the GTK_IM_MODULE_FILEenvironment variable for more details.

Gtk.rc_get_im_module_path()[source]

Returns:

a newly-allocated string containing the path in which to look for IM modules.

Return type:

str

Obtains the path in which to look for IM modules. See the documentation of the GTK_PATHenvironment variable for more details about looking up modules. This function is useful solely for utilities supplied with GTK+ and should not be used by applications under normal circumstances.

Gtk.rc_get_module_dir()[source]

Returns:

the directory. (Must be freed with GLib.free())

Return type:

str

Returns a directory in which GTK+ looks for theme engines. For full information about the search for theme engines, see the docs for GTK_PATH in Running GTK+ Applications.

Gtk.rc_get_style(widget)[source]

Parameters:

widget (Gtk.Widget) – a Gtk.Widget

Returns:

the resulting style. No refcount is added to the returned style, so if you want to save this style around, you should add a reference yourself.

Return type:

Gtk.Style

Finds all matching RC styles for a given widget, composites them together, and then creates aGtk.Style representing the composite appearance. (GTK+ actually keeps a cache of previously created styles, so a new style may not be created.)

Gtk.rc_get_style_by_paths(settings, widget_path, class_path, type)[source]

Parameters:

Returns:

A style created by matching with the supplied paths, or None if nothing matching was specified and the default style should be used. The returned value is owned by GTK+ as part of an internal cache, so you must call GObject.Object.ref() on the returned value if you want to keep a reference to it.

Return type:

Gtk.Style or None

Creates up a Gtk.Style from styles defined in a RC file by providing the raw components used in matching. This function may be useful when creating pseudo-widgets that should be themed like widgets but don’t actually have corresponding GTK+ widgets. An example of this would be items inside a GNOME canvas widget.

The action of Gtk.rc_get_style() is similar to:

gtk_widget_path (widget, NULL, &path, NULL); gtk_widget_class_path (widget, NULL, &class_path, NULL); gtk_rc_get_style_by_paths (gtk_widget_get_settings (widget), path, class_path, G_OBJECT_TYPE (widget));

Gtk.rc_get_theme_dir()[source]

Returns:

The directory (must be freed with GLib.free()).

Return type:

str

Returns the standard directory in which themes should be installed. (GTK+ does not actually use this directory itself.)

color:

a pointer to a Gdk.Color in which to store the result

Return type:

(int, color: Gdk.Color)

Parses a color in the format expected in a RC file.

Note that theme engines should use Gtk.rc_parse_color_full() in order to support symbolic colors.

Gtk.rc_parse_color_full(scanner, style)[source]

Parameters:

Returns:

GLib.TokenType.NONE if parsing succeeded, otherwise the token that was expected but not found

color:

a pointer to a Gdk.Color in which to store the result

True if the files were reread.

Return type:

bool

If the modification time on any previously read file for the default Gtk.Settings has changed, discard all style information and then reread all previously read RC files.

Gtk.rc_reparse_all_for_settings(settings, force_load)[source]

Parameters:

Returns:

True if the files were reread.

Return type:

bool

If the modification time on any previously read file for the given Gtk.Settings has changed, discard all style information and then reread all previously read RC files.

Gtk.rc_reset_styles(settings)[source]

Parameters:

settings (Gtk.Settings) – a Gtk.Settings

This function recomputes the styles for all widgets that use a particular Gtk.Settings object. (There is one Gtk.Settings object per Gdk.Screen, see Gtk.Settings.get_for_screen()); It is useful when some global parameter has changed that affects the appearance of all widgets, because when a widget gets a new style, it will both redraw and recompute any cached information about its appearance. As an example, it is used when the default font size set by the operating system changes. Note that this function doesn’t affect widgets that have a style set explicitly on them with Gtk.Widget.set_style().

New in version 2.4.

Gtk.show_uri(screen, uri, timestamp)[source]

Parameters:

Raises:

GLib.Error

Returns:

True on success, False on error

Return type:

bool

A convenience function for launching the default application to show the uri. Like Gtk.show_uri_on_window(), but takes a screen as transient parent instead of a window.

Note that this function is deprecated as it does not pass the necessary information for helpers to parent their dialog properly, when run from sandboxed applications for example.

New in version 2.14.

Deprecated since version 3.22: Use Gtk.show_uri_on_window() instead.

Gtk.show_uri_on_window(parent, uri, timestamp)[source]

Parameters:

Raises:

GLib.Error

Returns:

True on success, False on error

Return type:

bool

This is a convenience function for launching the default application to show the uri. The uri must be of a form understood by GIO (i.e. you need to install gvfs to get support for uri schemes such as http:// or ftp://, as only local files are handled by GIO itself). Typical examples are

Ideally the timestamp is taken from the event triggering the Gtk.show_uri() call. If timestamp is not known you can takeGdk.CURRENT_TIME.

This is the recommended call to be used as it passes information necessary for sandbox helpers to parent their dialogs properly.

New in version 3.22.

Gtk.stock_add(items)[source]

Parameters:

items ([Gtk.StockItem]) – a Gtk.StockItem or array of items

Registers each of the stock items in items. If an item already exists with the same stock ID as one of the items, the old item gets replaced. The stock items are copied, so GTK+ does not hold any pointer into items and items can be freed. UseGtk.stock_add_static() if items is persistent and GTK+ need not copy the array.

Deprecated since version 3.10.

Gtk.stock_add_static(items)[source]

Parameters:

items ([Gtk.StockItem]) – a Gtk.StockItem or array of Gtk.StockItem

Same as Gtk.stock_add(), but doesn’t copy items, soitems must persist until application exit.

Deprecated since version 3.10.

Gtk.stock_list_ids()[source]

Returns:

a list of known stock IDs

Return type:

[str]

Retrieves a list of all known stock IDs added to a Gtk.IconFactoryor registered with Gtk.stock_add(). The list must be freed with g_slist_free(), and each string in the list must be freed with GLib.free().

Deprecated since version 3.10.

Gtk.stock_lookup(stock_id)[source]

Parameters:

stock_id (str) – a stock item name

Returns:

a stock item or None if the stock icon isn’t known.

Return type:

Gtk.StockItem or None

Deprecated since version 3.10.

Gtk.stock_set_translate_func(domain, func, *data)[source]

Parameters:

Sets a function to be used for translating the label of a stock item.

If no function is registered for a translation domain,GLib.dgettext() is used.

The function is used for all stock items whosetranslation_domain matches domain. Note that it is possible to use strings different from the actual gettext translation domain of your application for this, as long as your Gtk.TranslateFunc uses the correct domain when calling dgettext(). This can be useful, e.g. when dealing with message contexts:

GtkStockItem items[] = { { MY_ITEM1, NC_("odd items", "Item 1"), 0, 0, "odd-item-domain" }, { MY_ITEM2, NC_("even items", "Item 2"), 0, 0, "even-item-domain" }, };

gchar * my_translate_func (const gchar *msgid, gpointer data) { gchar *msgctxt = data;

return (gchar*)g_dpgettext2 (GETTEXT_PACKAGE, msgctxt, msgid); }

...

gtk_stock_add (items, G_N_ELEMENTS (items)); gtk_stock_set_translate_func ("odd-item-domain", my_translate_func, "odd items"); gtk_stock_set_translate_func ("even-item-domain", my_translate_func, "even items");

Gtk.test_find_label(widget, label_pattern)[source]

Parameters:

Returns:

a Gtk.Label widget if any is found.

Return type:

Gtk.Widget

This function will search widget and all its descendants for a Gtk.Labelwidget with a text string matching label_pattern. The label_pattern may contain asterisks “*” and question marks “?” as placeholders, g_pattern_match() is used for the matching. Note that locales other than “C“ tend to alter (translate” label strings, so this function is genrally only useful in test programs with predetermined locales, see gtk_test_init() for more details.

New in version 2.14.

Gtk.test_find_sibling(base_widget, widget_type)[source]

Parameters:

Returns:

a widget of type widget_type if any is found.

Parameters:

Returns:

a valid widget if any is found or None.

Return type:

Gtk.Widget or None

Returns:

whether all actions neccessary for the button click simulation were carried out successfully.

Return type:

bool

This function will generate a button click (button press and button release event) in the middle of the first Gdk.Window found that belongs to widget. For windowless widgets like Gtk.Button (which returns False fromGtk.Widget.get_has_window()), this will often be an input-only event window. For other widgets, this is usually widget->window. Certain caveats should be considered when using this function, in particular because the mouse pointer is warped to the button click location, see Gdk.test_simulate_button() for details.

For windowless widgets like Gtk.Button (which returns False fromGtk.Widget.get_has_window()), this will often be an input-only event window. For other widgets, this is usually widget->window. Certain caveats should be considered when using this function, in particular because the mouse pointer is warped to the key press location, see Gdk.test_simulate_key() for details.

New in version 2.14.

Gtk.test_widget_wait_for_draw(widget)[source]

Parameters:

widget (Gtk.Widget) – the widget to wait for

Enters the main loop and waits for widget to be “drawn”. In this context that means it waits for the frame clock of widget to have run a full styling, layout and drawing cycle.

New in version 3.10.

Gtk.tree_get_row_drag_data(selection_data)[source]

Parameters:

selection_data (Gtk.SelectionData) – a Gtk.SelectionData

Returns:

True if selection_data had target type %GTK_TREE_MODEL_ROW and is otherwise valid

tree_model:

a Gtk.TreeModel

path:

row in tree_model

Return type:

(bool, tree_model: Gtk.TreeModel or None, path: Gtk.TreePath or None)

Obtains a tree_model and path from selection data of target type %GTK_TREE_MODEL_ROW. Normally called from a drag_data_received handler. This function can only be used if selection_data originates from the same process that’s calling this function, because a pointer to the tree model is being passed around. If you aren’t in the same process, then you’ll get memory corruption. In the Gtk.TreeDragDest drag_data_received handler, you can assume that selection data of type %GTK_TREE_MODEL_ROW is in from the current process. The returned path must be freed withGtk.TreePath.free().

Gtk.tree_row_reference_deleted(proxy, path)[source]

Parameters:

Lets a set of row reference created byGtk.TreeRowReference.new_proxy() know that the model emitted the Gtk.TreeModel ::row-deleted signal.

Gtk.tree_row_reference_inserted(proxy, path)[source]

Parameters:

Lets a set of row reference created byGtk.TreeRowReference.new_proxy() know that the model emitted the Gtk.TreeModel ::row-inserted signal.

Gtk.tree_set_row_drag_data(selection_data, tree_model, path)[source]

Parameters:

Returns:

True if the Gtk.SelectionData had the proper target type to allow us to set a tree row

Return type:

bool

Sets selection data of target type %GTK_TREE_MODEL_ROW. Normally used in a drag_data_get handler.

Gtk.true()[source]

Returns:

True

Return type:

bool

All this function does it to return True.

This can be useful for example if you want to inhibit the deletion of a window. Of course you should not do this as the user expects a reaction from clicking the close icon of the window…
