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. */ struct _GtkWidgetClass { GInitiallyUnownedClass parent_class;
