Depending on the orientation parameter, the passed * for_size can be interpreted as width or height. A widget will never be * allocated less than its minimum size. * @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. * @key_press_event: Signal emitted when a key is pressed. * @key_release_event: Signal is emitted when a key is released. * @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. * @get_accessible: Returns the accessible object that describes the * widget to an assistive technology. * @display_changed: Signal emitted when the #GdkDisplay 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. * @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. * @style_updated: Signal emitted when the GtkStyleContext of a widget * is changed. * @touch_event: * @snapshot: Signal emitted when a widget is supposed to create a snapshot * of itself. */ struct _GtkWidgetClass { GInitiallyUnownedClass parent_class;
