* @hide: Signal emitted when widget is hidden.
* @map: Signal 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.
* @unmap: Signal emitted when widget is going to be unmapped, which
* means that either it or any of its parents up to the toplevel
* widget have been set as hidden.
* @realize: Signal 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).
* @unrealize: Signal emitted when the GdkWindow associated with
* widget is destroyed, which means that gtk_widget_unrealize() has
* been called or the widget has been unmapped (that is, it is going
* to be hidden).
* @size_allocate: Signal emitted to get the widget allocation.
* @state_changed: Signal emitted when the widget state
* changes. Deprecated: 3.0
* @state_flags_changed: Signal emitted when the widget state changes,
* see gtk_widget_get_state_flags().
* @parent_set: Signal emitted when a new parent has been set on a
* widget.
* @hierarchy_changed: Signal emitted when the anchored state of a
* widget changes.
* @style_set: Signal emitted when a new style has been set on a
* widget. Deprecated: 3.0
* @direction_changed: Signal emitted when the text direction of a
* widget changes.
* @grab_notify: Signal 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.
* @child_notify: Signal emitted for each child property that has
* changed on an object.
* @draw: Signal emitted when a widget is supposed to render itself.
* @get_request_mode: This allows a widget to tell its parent container whether
* it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
* %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
* %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH means the widget prefers to have
* #GtkWidgetClass.get_preferred_width() called and then
* #GtkWidgetClass.get_preferred_height_for_width().
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
* width-for-height geometry management for a said widget and is the
* default return.
* It’s important to note (as described below) that any widget
* which trades height-for-width or width-for-height must respond properly
* to both of the virtual methods #GtkWidgetClass.get_preferred_height_for_width()
* and #GtkWidgetClass.get_preferred_width_for_height() since it might be
* queried in either #GtkSizeRequestMode by its parent container.
* @get_preferred_height: This is called by containers to obtain the minimum
* and natural height of a widget. A widget that does not actually trade
* any height for width or width for height only has to implement these
* two virtual methods (#GtkWidgetClass.get_preferred_width() and
* #GtkWidgetClass.get_preferred_height()).
* @get_preferred_width_for_height: This is analogous to
* #GtkWidgetClass.get_preferred_height_for_width() except that it
* operates in the oposite orientation. It’s rare that a widget actually
* does %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT requests but this can happen
* when, for example, a widget or container gets additional columns to
* compensate for a smaller allocated height.
* @get_preferred_width: This is called by containers to obtain the minimum
* and natural width of a widget. A widget will never be allocated a width
* less than its minimum and will only ever be allocated a width greater
* than the natural width once all of the said widget’s siblings have
* received their natural widths.
* Furthermore, a widget will only ever be allocated a width greater than
* its natural width if it was configured to receive extra expand space
* from its parent container.
* @get_preferred_height_for_width: This is similar to
* #GtkWidgetClass.get_preferred_height() except that it is passed a
* contextual width to request height for. By implementing this virtual
* method it is possible for a #GtkLabel to tell its parent how much height
* would be required if the label were to be allocated a said width.
* @mnemonic_activate: Activates the @widget if @group_cycling is
* %FALSE, and just grabs the focus if @group_cycling is %TRUE.
* @grab_focus: Causes @widget to have the keyboard focus for the
* #GtkWindow it’s inside.
* @focus:
* @move_focus: Signal emitted when a change of focus is requested
* @keynav_failed: Signal emitted if keyboard navigation fails.
* @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. "key-press-event") and finally a generic "event-after"
* signal.
* @button_press_event: Signal will be emitted when a button
* (typically from a mouse) is pressed.
* @button_release_event: Signal will be emitted when a button
* (typically from a mouse) is released.
* @scroll_event: Signal emitted when a button in the 4 to 7 range is
* pressed.
* @motion_notify_event: Signal emitted when the pointer moves over
* the widget’s #GdkWindow.
* @delete_event: Signal emitted if a user requests that a toplevel
* window is closed.
* @destroy_event: Signal is emitted when a #GdkWindow is destroyed.
* @key_press_event: Signal emitted when a key is pressed.
* @key_release_event: Signal is emitted when a key is released.
* @enter_notify_event: Signal event will be emitted when the pointer
* enters the widget’s window.
* @leave_notify_event: Will be emitted when the pointer leaves the
* widget’s window.
* @configure_event: Signal will be emitted when the size, position or
* stacking of the widget’s window has changed.
* @focus_in_event: Signal emitted when the keyboard focus enters the
* widget’s window.
* @focus_out_event: Signal emitted when the keyboard focus leaves the
* widget’s window.
* @map_event: Signal emitted when the widget’s window is mapped.
* @unmap_event: Signal will be emitted when the widget’s window is
* unmapped.
* @property_notify_event: Signal will be emitted when a property on
* the widget’s window has been changed or deleted.
* @selection_clear_event: Signal will be emitted when the the
* widget’s window has lost ownership of a selection.
* @selection_request_event: Signal will be emitted when another
* client requests ownership of the selection owned by the widget's
* window.
* @selection_notify_event:
* @proximity_in_event:
* @proximity_out_event:
* @visibility_notify_event: Signal emitted when the widget’s window is
* obscured or unobscured.
* @window_state_event: Signal emitted when the state of the toplevel
* window associated to the widget changes.
* @damage_event: Signal emitted when a redirected window belonging to
* widget gets drawn into.
* @grab_broken_event: Signal emitted when a pointer or keyboard grab
* on a window belonging to widget gets broken.
* @selection_get:
* @selection_received:
* @drag_begin: Signal emitted on the drag source when a drag is
* started.
* @drag_end: Signal emitted on the drag source when a drag is
* finished.
* @drag_data_get: Signal emitted on the drag source when the drop
* site requests the data which is dragged.
* @drag_data_delete: Signal emitted on the drag source when a drag
* with the action %GDK_ACTION_MOVE is successfully completed.
* @drag_leave: Signal emitted on the drop site when the cursor leaves
* the widget.
* @drag_motion: signal emitted on the drop site when the user moves
* the cursor over the widget during a drag.
* @drag_drop: Signal emitted on the drop site when the user drops the
* data onto the widget.
* @drag_data_received: Signal emitted on the drop site when the
* dragged data has been received.
* @drag_failed: Signal emitted on the drag source when a drag has
* failed.
* @popup_menu: Signal emitted whenever a widget should pop up a
* context menu.
* @show_help:
* @get_accessible: Returns the accessible object that describes the
* widget to an assistive technology.
* @screen_changed: Signal emitted when the screen of a widget has
* changed.
* @can_activate_accel: Signal allows applications and derived widgets
* to override the default GtkWidget handling for determining whether
* an accelerator can be activated.
* @composited_changed: Signal emitted when the composited status of
* widgets screen changes. See gdk_screen_is_composited().
* @query_tooltip: Signal emitted when “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.
* @compute_expand: Computes whether a container should give this
* widget extra space when possible.
* @adjust_size_request: Convert an initial size request from a widget's
* #GtkSizeRequestMode virtual method implementations into a size request to
* be used by parent containers in laying out the widget.
* adjust_size_request adjusts from a child widget's
* original request to what a parent container should
* use for layout. The @for_size argument will be -1 if the request should
* not be for a particular size in the opposing orientation, i.e. if the
* request is not height-for-width or width-for-height. If @for_size is
* greater than -1, it is the proposed allocation in the opposing
* orientation that we need the request for. Implementations of
* adjust_size_request should chain up to the default implementation,
* which applies #GtkWidget’s margin properties and imposes any values
* from gtk_widget_set_size_request(). Chaining up should be last,
* after your subclass adjusts the request, so
* #GtkWidget can apply constraints and add the margin properly.
* @adjust_size_allocation: Convert an initial size allocation assigned
* by a #GtkContainer using gtk_widget_size_allocate(), into an actual
* size allocation to be used by the widget. adjust_size_allocation
* adjusts to a child widget’s actual allocation
* from what a parent container computed for the
* child. The adjusted allocation must be entirely within the original
* allocation. In any custom implementation, chain up to the default
* #GtkWidget implementation of this method, which applies the margin
* and alignment properties of #GtkWidget. Chain up
* before performing your own adjustments so your
* own adjustments remove more allocation after the #GtkWidget base
* class has already removed margin and alignment. The natural size
* passed in should be adjusted in the same way as the allocated size,
* which allows adjustments to perform alignments or other changes
* based on natural size.
* @style_updated: Signal emitted when the GtkStyleContext of a widget
* is changed.
* @touch_event:
* @get_preferred_height_and_baseline_for_width:
* @adjust_baseline_request:
* @adjust_baseline_allocation:
* @queue_draw_region: Invalidates the area of widget defined by
* region by calling gdk_window_invalidate_region() on the widget's
* window and all its child windows.
