Class

GtkAboutDialog

Description [src]

class Gtk.AboutDialog : Gtk.Dialog {
  parent_instance: GtkDialog
}

The GtkAboutDialog offers a simple way to display information about a program like its logo, name, copyright, website and license. It is also possible to give credits to the authors, documenters, translators and artists who have worked on the program. An about dialog is typically opened when the user selects the About option from the Help menu. All parts of the dialog are optional.

About dialogs often contain links and email addresses. GtkAboutDialog displays these as clickable links. By default, it calls gtk_show_uri_on_window() when a user clicks one. The behaviour can be overridden with the GtkAboutDialog::activate-link signal.

To specify a person with an email address, use a string like “Edgar Allan Poe “. To specify a website with a title, use a string like “GTK+ team http://www.gtk.org”.

To make constructing a GtkAboutDialog as convenient as possible, you can use the function gtk_show_about_dialog() which constructs and shows a dialog and keeps it around so that it can be shown again.

Note that GTK+ sets a default title of _("About %s") on the dialog window (where \%s is replaced by the name of the application, but in order to ensure proper translation of the title, applications should set the title property explicitly when constructing a GtkAboutDialog, as shown in the following example:

GdkPixbuf *example_logo = gdk_pixbuf_new_from_file ("./logo.png", NULL);
gtk_show_about_dialog (NULL,
                       "program-name", "ExampleCode",
                       "logo", example_logo,
                       "title", _("About ExampleCode"),
                       NULL);

It is also possible to show a GtkAboutDialog like any other GtkDialog, e.g. using gtk_dialog_run(). In this case, you might need to know that the “Close” button returns the #GTK_RESPONSE_CANCEL response id.

Methods inherited from GtkDialog (14)
gtk_dialog_add_action_widget

Adds an activatable widget to the action area of a GtkDialog, connecting a signal handler that will emit the GtkDialog::response signal on the dialog when the widget is activated. The widget is appended to the end of the dialog’s action area. If you want to add a non-activatable widget, simply pack it into the action_area field of the GtkDialog struct.

gtk_dialog_add_button

Adds a button with the given text and sets things up so that clicking the button will emit the GtkDialog::response signal with the given response_id. The button is appended to the end of the dialog’s action area. The button widget is returned, but usually you don’t need it.

gtk_dialog_add_buttons

Adds more buttons, same as calling gtk_dialog_add_button() repeatedly. The variable argument list should be NULL-terminated as with gtk_dialog_new_with_buttons(). Each button must have both text and response ID.

gtk_dialog_get_action_area

Returns the action area of dialog.

Available since: 2.14

Deprecated since: 3.12

gtk_dialog_get_content_area

Returns the content area of dialog.

Available since: 2.14

gtk_dialog_get_header_bar

Returns the header bar of dialog. Note that the headerbar is only used by the dialog if the GtkDialog:use-header-bar property is TRUE.

Available since: 3.12

gtk_dialog_get_response_for_widget

Gets the response id of a widget in the action area of a dialog.

Available since: 2.8

gtk_dialog_get_widget_for_response

Gets the widget button that uses the given response ID in the action area of a dialog.

Available since: 2.20

gtk_dialog_response

Emits the GtkDialog::response signal with the given response ID. Used to indicate that the user has responded to the dialog in some way; typically either you or gtk_dialog_run() will be monitoring the ::response signal and take appropriate action.

gtk_dialog_run

Blocks in a recursive main loop until the dialog either emits the GtkDialog::response signal, or is destroyed. If the dialog is destroyed during the call to gtk_dialog_run(), gtk_dialog_run() returns

GTK_RESPONSE_NONE. Otherwise, it returns the response ID from the

::response signal emission.

gtk_dialog_set_alternative_button_order

Sets an alternative button order. If the GtkSettings:gtk-alternative-button-order setting is set to TRUE, the dialog buttons are reordered according to the order of the response ids passed to this function.

Available since: 2.6

Deprecated since: 3.10

gtk_dialog_set_alternative_button_order_from_array

Sets an alternative button order. If the GtkSettings:gtk-alternative-button-order setting is set to TRUE, the dialog buttons are reordered according to the order of the response ids in new_order.

Available since: 2.6

Deprecated since: 3.10

gtk_dialog_set_default_response

Sets the last widget in the dialog’s action area with the given response_id as the default widget for the dialog. Pressing “Enter” normally activates the default widget.

gtk_dialog_set_response_sensitive

Calls gtk_widget_set_sensitive (widget,setting) for each widget in the dialog’s action area with the given response_id. A convenient way to sensitize/desensitize dialog buttons.

Methods inherited from GtkWindow (109)
gtk_window_activate_default

Activates the default widget for the window, unless the current focused widget has been configured to receive the default action (see gtk_widget_set_receives_default()), in which case the focused widget is activated.

gtk_window_activate_focus

Activates the current focused widget within the window.

gtk_window_activate_key

Activates mnemonics and accelerators for this GtkWindow. This is normally called by the default ::key_press_event handler for toplevel windows, however in some cases it may be useful to call this directly when overriding the standard key handling for a toplevel window.

Available since: 2.4

gtk_window_add_accel_group

Associate accel_group with window, such that calling gtk_accel_groups_activate() on window will activate accelerators in accel_group.

gtk_window_add_mnemonic

Adds a mnemonic to this window.

gtk_window_begin_move_drag

Starts moving a window. This function is used if an application has window movement grips. When GDK can support it, the window movement will be done using the standard mechanism for the [window manager][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window movement, potentially not all that well, depending on the windowing system.

gtk_window_begin_resize_drag

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][gtk-X11-arch] or windowing system. Otherwise, GDK will try to emulate window resizing, potentially not all that well, depending on the windowing system.

gtk_window_close

Requests that the window is closed, similar to what happens when a window manager close button is clicked.

Available since: 3.10

gtk_window_deiconify

Asks to deiconify (i.e. unminimize) the specified window. Note that you shouldn’t assume the window is definitely deiconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch])) could iconify it again before your code which assumes deiconification gets to run.

gtk_window_fullscreen

Asks to place window in the fullscreen state. Note that you shouldn’t assume the window is definitely full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could unfullscreen it again, and not all window managers honor requests to fullscreen windows. But normally the window will end up fullscreen. Just don’t write code that crashes if not.

Available since: 2.2

gtk_window_fullscreen_on_monitor

Asks to place window in the fullscreen state. Note that you shouldn’t assume the window is definitely full screen afterward.

Available since: 3.18

gtk_window_get_accept_focus

Gets the value set by gtk_window_set_accept_focus().

Available since: 2.4

gtk_window_get_application

Gets the GtkApplication associated with the window (if any).

Available since: 3.0

gtk_window_get_attached_to

Fetches the attach widget for this window. See gtk_window_set_attached_to().

Available since: 3.4

gtk_window_get_decorated

Returns whether the window has been set to have decorations such as a title bar via gtk_window_set_decorated().

gtk_window_get_default_size

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 dimension, so the “natural” size of the window will be used.

gtk_window_get_default_widget

Returns the default widget for window. See gtk_window_set_default() for more details.

Available since: 2.14

gtk_window_get_deletable

Returns whether the window has been set to have a close button via gtk_window_set_deletable().

Available since: 2.10

gtk_window_get_destroy_with_parent

Returns whether the window will be destroyed with its transient parent. See gtk_window_set_destroy_with_parent ().

gtk_window_get_focus

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 gtk_widget_has_focus (widget) will not be TRUE for the widget.

gtk_window_get_focus_on_map

Gets the value set by gtk_window_set_focus_on_map().

Available since: 2.6

gtk_window_get_focus_visible

Gets the value of the GtkWindow:focus-visible property.

Available since: 3.2

gtk_window_get_gravity

Gets the value set by gtk_window_set_gravity().

Methods inherited from GtkBin (1)
gtk_bin_get_child

Gets the child of the GtkBin, or NULL if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

Methods inherited from GtkContainer (33)
gtk_container_add

Adds widget to container. Typically used for simple containers such as GtkWindow, GtkFrame, or GtkButton; for more complicated layout containers such as GtkBox or GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.

gtk_container_add_with_properties

Adds widget to container, setting child properties at the same time. See gtk_container_add() and gtk_container_child_set() for more details.

gtk_container_check_resize
No description available.
gtk_container_child_get

Gets the values of one or more child properties for child and container.

gtk_container_child_get_property

Gets the value of a child property for child and container.

gtk_container_child_get_valist

Gets the values of one or more child properties for child and container.

gtk_container_child_notify

Emits a GtkWidget::child-notify signal for the [child property][child-properties] child_property on the child.

Available since: 3.2

gtk_container_child_notify_by_pspec

Emits a GtkWidget::child-notify signal for the [child property][child-properties] specified by pspec on the child.

Available since: 3.18

gtk_container_child_set

Sets one or more child properties for child and container.

gtk_container_child_set_property

Sets a child property for child and container.

gtk_container_child_set_valist

Sets one or more child properties for child and container.

gtk_container_child_type

Returns the type of the children supported by the container.

gtk_container_forall

Invokes callback on each direct child of container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.

gtk_container_foreach

Invokes callback on each non-internal child of container. See gtk_container_forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.

gtk_container_get_border_width

Retrieves the border width of the container. See gtk_container_set_border_width().

gtk_container_get_children

Returns the container’s non-internal children. See gtk_container_forall() for details on what constitutes an “internal” child.

gtk_container_get_focus_chain

Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable_widgets and returns FALSE.

Deprecated since: 3.24

gtk_container_get_focus_child

Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus().

Available since: 2.14

gtk_container_get_focus_hadjustment

Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().

gtk_container_get_focus_vadjustment

Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().

gtk_container_get_path_for_child

Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.

gtk_container_get_resize_mode

Returns the resize mode for the container. See gtk_container_set_resize_mode ().

Deprecated since: 3.12

gtk_container_propagate_draw

When a container receives a call to the draw function, it must send synthetic GtkWidget::draw calls to all children that don’t have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the cr the container received.

Methods inherited from GtkWidget (263)
gtk_widget_activate

For widgets that can be “activated” (buttons, menu items, etc.) this function activates them. Activation is what happens when you press Enter on a widget during key navigation. If widget isn’t activatable, the function returns FALSE.

gtk_widget_add_accelerator

Installs an accelerator for this widget in accel_group that causes accel_signal to be emitted if the accelerator is activated. The accel_group needs to be added to the widget’s toplevel via gtk_window_add_accel_group(), and the signal must be of type G_SIGNAL_ACTION. Accelerators added through this function are not user changeable during runtime. If you want to support accelerators that can be changed by the user, use gtk_accel_map_add_entry() and gtk_widget_set_accel_path() or gtk_menu_item_set_accel_path() instead.

gtk_widget_add_device_events

Adds the device events in the bitfield events to the event mask for widget. See gtk_widget_set_device_events() for details.

Available since: 3.0

gtk_widget_add_events

Adds the events in the bitfield events to the event mask for widget. See gtk_widget_set_events() and the [input handling overview][event-masks] for details.

gtk_widget_add_mnemonic_label

Adds a widget to the list of mnemonic labels for this widget. (See gtk_widget_list_mnemonic_labels()). Note the list of mnemonic labels for the widget is cleared when the widget is destroyed, so the caller must make sure to update its internal state at this point as well, by using a connection to the GtkWidget::destroy signal or a weak notifier.

Available since: 2.4

gtk_widget_add_tick_callback

Queues an animation frame update and adds a callback to be called before each frame. Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames. The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a GtkLabel), then you will have to call gtk_widget_queue_resize() or gtk_widget_queue_draw_area() yourself.

Available since: 3.8

gtk_widget_can_activate_accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the GtkWidget::can-activate-accel signal on widget; if the signal isn’t overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

Available since: 2.4

gtk_widget_child_focus

This function is used by custom widget implementations; if you’re writing an app, you’d use gtk_widget_grab_focus() to move the focus to a particular widget, and gtk_container_set_focus_chain() to change the focus tab order. So you may want to investigate those functions instead.

gtk_widget_child_notify

Emits a GtkWidget::child-notify signal for the [child property][child-properties] child_property on widget.

gtk_widget_class_path

Same as gtk_widget_path(), but always uses the name of a widget’s type, never uses a custom name set with gtk_widget_set_name().

Deprecated since: 3.0

gtk_widget_compute_expand

Computes whether a container should give this widget extra space when possible. Containers should check this, rather than looking at gtk_widget_get_hexpand() or gtk_widget_get_vexpand().

gtk_widget_create_pango_context

Creates a new PangoContext with the appropriate font map, font options, font description, and base direction for drawing text for this widget. See also gtk_widget_get_pango_context().

gtk_widget_create_pango_layout

Creates a new PangoLayout with the appropriate font map, font description, and base direction for drawing text for this widget.

gtk_widget_destroy

Destroys a widget.

gtk_widget_destroyed

This function sets *widget_pointer to NULL if widget_pointer != NULL. It’s intended to be used as a callback connected to the “destroy” signal of a widget. You connect gtk_widget_destroyed() as a signal handler, and pass the address of your widget variable as user data. Then when the widget is destroyed, the variable will be set to NULL. Useful for example to avoid multiple copies of the same dialog.

gtk_widget_device_is_shadowed

Returns TRUE if device has been shadowed by a GTK+ device grab on another widget, so it would stop sending events to widget. This may be used in the GtkWidget::grab-notify signal to check for specific devices. See gtk_device_grab_add().

Available since: 3.0

gtk_drag_begin

This function is equivalent to gtk_drag_begin_with_coordinates(), passing -1, -1 as coordinates.

Deprecated since: 3.10

gtk_drag_begin_with_coordinates

Initiates a drag on the source side. The function only needs to be used when the application is starting drags itself, and is not needed when gtk_drag_source_set() is used.

Available since: 3.10

gtk_drag_check_threshold

Checks to see if a mouse drag starting at (start_x, start_y) and ending at (current_x, current_y) has passed the GTK+ drag threshold, and thus should trigger the beginning of a drag-and-drop operation.

gtk_drag_dest_add_image_targets

Add the image targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_image_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_text_targets

Add the text targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_text_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_add_uri_targets

Add the URI targets supported by GtkSelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use gtk_target_list_add_uri_targets() and gtk_drag_dest_set_target_list().

Available since: 2.6

gtk_drag_dest_find_target

Looks for a match between the supported targets of context and the dest_target_list, returning the first matching target, otherwise returning GDK_NONE. dest_target_list should usually be the return value from gtk_drag_dest_get_target_list(), but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a drag_motion handler that passes the correct target list to this function.

Signals

Gtk.AboutDialog::activate-link

The signal which gets emitted to activate a URI. Applications may connect to it to override the default behaviour, which is to call gtk_show_uri_on_window().

Available since: 2.24

Signals inherited from GtkDialog (2)
Gtk.Dialog::close

The ::close signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user uses a keybinding to close the dialog.

Gtk.Dialog::response

Emitted when an action widget is clicked, the dialog receives a delete event, or the application programmer calls gtk_dialog_response(). On a delete event, the response ID is #GTK_RESPONSE_DELETE_EVENT. Otherwise, it depends on which action widget was clicked.

Signals inherited from GtkWindow (5)
Gtk.Window::activate-default

The ::activate-default signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user activates the default widget of window.

Gtk.Window::activate-focus

The ::activate-focus signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user activates the currently focused widget of window.

Gtk.Window::enable-debugging

The ::enable-debugging signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user enables or disables interactive debugging. When toggle is TRUE, interactive debugging is toggled on or off, when it is FALSE, the debugger will be pointed at the widget under the pointer.

Gtk.Window::keys-changed

The ::keys-changed signal gets emitted when the set of accelerators or mnemonics that are associated with window changes.

Gtk.Window::set-focus

This signal is emitted whenever the currently focused widget in this window changes.

Available since: 2.24

No description available.
Gtk.Widget::button-press-event

The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.

Gtk.Widget::button-release-event

The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.

Gtk.Widget::can-activate-accel

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This signal is present to allow applications and derived widgets to override the default GtkWidget handling for determining whether an accelerator can be activated.

Gtk.Widget::child-notify

The ::child-notify signal is emitted for each [child property][child-properties] that has changed on an object. The signal’s detail holds the property name.

Gtk.Widget::composited-changed

The ::composited-changed signal is emitted when the composited status of widgets screen changes. See gdk_screen_is_composited().

Deprecated since: 3.22

Gtk.Widget::configure-event

The ::configure-event signal will be emitted when the size, position or stacking of the widgets window has changed.

Gtk.Widget::damage-event

Emitted when a redirected window belonging to widget gets drawn into. The region/area members of the event shows what area of the redirected drawable was drawn into.

Available since: 2.14

Gtk.Widget::delete-event

The ::delete-event signal is emitted if a user requests that a toplevel window is closed. The default handler for this signal destroys the window. Connecting gtk_widget_hide_on_delete() to this signal will cause the window to be hidden instead, so that it can later be shown again without reconstructing it.

Gtk.Widget::destroy

Signals that all holders of a reference to the widget should release the reference that they hold. May result in finalization of the widget if all references are released.

Gtk.Widget::destroy-event

The ::destroy-event signal is emitted when a GdkWindow is destroyed. You rarely get this signal, because most widgets disconnect themselves from their window before they destroy it, so no widget owns the window at destroy time.

Gtk.Widget::direction-changed

The ::direction-changed signal is emitted when the text direction of a widget changes.

Gtk.Widget::drag-begin

The ::drag-begin signal is emitted on the drag source when a drag is started. A typical reason to connect to this signal is to set up a custom drag icon with e.g. gtk_drag_source_set_icon_pixbuf().

Gtk.Widget::drag-data-delete

The ::drag-data-delete signal is emitted on the drag source when a drag with the action GDK_ACTION_MOVE is successfully completed. The signal handler is responsible for deleting the data that has been dropped. What “delete” means depends on the context of the drag operation.

Gtk.Widget::drag-data-get

The ::drag-data-get signal is emitted on the drag source when the drop site requests the data which is dragged. It is the responsibility of the signal handler to fill data with the data in the format which is indicated by info. See gtk_selection_data_set() and gtk_selection_data_set_text().

Gtk.Widget::drag-data-received

The ::drag-data-received signal is emitted on the drop site when the dragged data has been received. If the data was received in order to determine whether the drop will be accepted, the handler is expected to call gdk_drag_status() and not finish the drag. If the data was received in response to a GtkWidget::drag-drop signal (and this is the last target to be received), the handler for this signal is expected to process the received data and then call gtk_drag_finish(), setting the success parameter depending on whether the data was processed successfully.

Gtk.Widget::drag-drop

The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a GtkWidget::drag-data-received handler which gets triggered by calling gtk_drag_get_data() to receive the data for one or more of the supported targets.

Gtk.Widget::drag-end

The ::drag-end signal is emitted on the drag source when a drag is finished. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-begin.

Gtk.Widget::drag-failed

The ::drag-failed signal is emitted on the drag source when a drag has failed. The signal handler may hook custom code to handle a failed DnD operation based on the type of error, it returns TRUE is the failure has been already handled (not showing the default “drag operation failed” animation), otherwise it returns FALSE.

Available since: 2.12

Gtk.Widget::drag-leave

The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in GtkWidget::drag-motion, e.g. undo highlighting with gtk_drag_unhighlight().

Gtk.Widget::drag-motion

The ::drag-motion signal is emitted on the drop site when the user moves the cursor over the widget during a drag. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns FALSE and no further processing is necessary. Otherwise, the handler returns TRUE. In this case, the handler is responsible for providing the necessary information for displaying feedback to the user, by calling gdk_drag_status().

Gtk.Widget::draw

This signal is emitted when a widget is supposed to render itself. The widgets top left corner must be painted at the origin of the passed in context and be sized to the values returned by gtk_widget_get_allocated_width() and gtk_widget_get_allocated_height().

Available since: 3.0

Gtk.Widget::enter-notify-event

The ::enter-notify-event will be emitted when the pointer enters the widgets window.

Gtk.Widget::event

The GTK+ main loop will emit three signals for each GDK event delivered to a widget: one generic ::event signal, another, more specific, signal that matches the type of event delivered (e.g. GtkWidget::key-press-event) and finally a generic GtkWidget::event-after signal.

Gtk.Widget::event-after

After the emission of the GtkWidget::event signal and (optionally) the second more specific signal, ::event-after will be emitted regardless of the previous two signals handlers return values.

Gtk.Widget::focus
No description available.
Gtk.Widget::focus-in-event

The ::focus-in-event signal will be emitted when the keyboard focus enters the widgets window.

Gtk.Widget::focus-out-event

The ::focus-out-event signal will be emitted when the keyboard focus leaves the widgets window.

Gtk.Widget::grab-broken-event

Emitted when a pointer or keyboard grab on a window belonging to widget gets broken.

Available since: 2.8

Gtk.Widget::grab-focus
No description available.
Gtk.Widget::grab-notify

The ::grab-notify signal is emitted when a widget becomes shadowed by a GTK+ grab (not a pointer or keyboard grab) on another widget, or when it becomes unshadowed due to a grab being removed.

Gtk.Widget::hide

The ::hide signal is emitted when widget is hidden, for example with gtk_widget_hide().

Gtk.Widget::hierarchy-changed

The ::hierarchy-changed signal is emitted when the anchored state of a widget changes. A widget is “anchored” when its toplevel ancestor is a GtkWindow. This signal is emitted when a widget changes from un-anchored to anchored or vice-versa.

Gtk.Widget::key-press-event

The ::key-press-event signal is emitted when a key is pressed. The signal emission will reoccur at the key-repeat rate when the key is kept pressed.

Gtk.Widget::key-release-event

The ::key-release-event signal is emitted when a key is released.

Gtk.Widget::keynav-failed

Gets emitted if keyboard navigation fails. See gtk_widget_keynav_failed() for details.

Available since: 2.12

Gtk.Widget::leave-notify-event

The ::leave-notify-event will be emitted when the pointer leaves the widgets window.

Gtk.Widget::map

The ::map signal is emitted when widget is going to be mapped, that is when the widget is visible (which is controlled with gtk_widget_set_visible()) and all its parents up to the toplevel widget are also visible. Once the map has occurred, GtkWidget::map-event will be emitted.

Gtk.Widget::map-event

The ::map-event signal will be emitted when the widgets window is mapped. A window is mapped when it becomes visible on the screen.

Gtk.Widget::mnemonic-activate

The default handler for this signal activates widget if group_cycling is FALSE, or just makes widget grab focus if group_cycling is TRUE.

Gtk.Widget::motion-notify-event

The ::motion-notify-event signal is emitted when the pointer moves over the widget’s GdkWindow.

Gtk.Widget::move-focus
No description available.
Gtk.Widget::parent-set

The ::parent-set signal is emitted when a new parent has been set on a widget.

Gtk.Widget::popup-menu

This signal gets emitted whenever a widget should pop up a context menu. This usually happens through the standard key binding mechanism; by pressing a certain key while a widget is focused, the user can cause the widget to pop up a menu. For example, the GtkEntry widget creates a menu with clipboard commands. See the [Popup Menu Migration Checklist][checklist-popup-menu] for an example of how to use this signal.

Gtk.Widget::property-notify-event

The ::property-notify-event signal will be emitted when a property on the widgets window has been changed or deleted.

Gtk.Widget::proximity-in-event

To receive this signal the GdkWindow associated to the widget needs to enable the #GDK_PROXIMITY_IN_MASK mask.

Gtk.Widget::proximity-out-event

To receive this signal the GdkWindow associated to the widget needs to enable the #GDK_PROXIMITY_OUT_MASK mask.

Gtk.Widget::query-tooltip

Emitted when GtkWidget:has-tooltip is TRUE and the hover timeout has expired with the cursor hovering “above” widget; or emitted when widget got focus in keyboard mode.

Available since: 2.12

Gtk.Widget::realize

The ::realize signal is emitted when widget is associated with a GdkWindow, which means that gtk_widget_realize() has been called or the widget has been mapped (that is, it is going to be drawn).

Gtk.Widget::screen-changed

The ::screen-changed signal gets emitted when the screen of a widget has changed.

Gtk.Widget::scroll-event

The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.
