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: Vfunc for gtk_widget_child_focus() + * @set_focus_child: Sets the focused child of a widget. Must chain up + * @move_focus: Signal emitted when a change of focus is requested + * @keynav_failed: Signal emitted if keyboard navigation fails. + * @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. + * @css_changed: Vfunc called when the CSS used by widget was changed. Widgets + * should then discard their caches that depend on CSS and queue resizes or + * redraws accordingly. The default implementation will take care of this for + * all the default CSS properties, so implementations must chain up. + * @system_setting_changed: Emitted when a system setting was changed. Must chain up. + * @snapshot: Vfunc called when a new snapshot of the widget has to be taken. + * @contains: Vfunc for gtk_widget_contains(). + */ +struct _GtkWidgetClass +{ + GInitiallyUnownedClass parent_class;
