/**
* GtkWidgetClass:
* @parent_class: The object class structure needs to be the first
* element in the widget class structure in order for the class mechanism
* to work correctly. This allows a GtkWidgetClass pointer to be cast to
* a GObjectClass pointer.
* @activate_signal: The signal to emit when a widget of this class is
* activated, gtk_widget_activate() handles the emission.
* Implementation of this signal is optional.
* @destroy: Signals that all holders of a reference to the widget
* should release the reference that they hold.
* @show: Signal emitted when widget is shown
* @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
* #GdkSurface, 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 GdkSurface 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).
* @root: Called when the widget gets added to a #GtkRoot widget. Must chain up
* @unroot: Called when the widget is about to be removed from its #GtkRoot widget. Must chain up
* @size_allocate: Signal emitted to get the widget allocation.
* @state_flags_changed: Signal emitted when the widget state changes,
* see gtk_widget_get_state_flags().
* @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.
* @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.measure() called first to get the default width (passing
* a for_size of -1), then again to get the height for said default width.
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
* width-for-height geometry management for said widget and is the
* default return.
* It’s important to note that any widget
* which trades height-for-width or width-for-height must respond properly
* to a for_size value >= -1 passed to #GtkWidgetClass.measure, for both
* possible orientations.
* @measure: This is called by containers to obtain the minimum and natural
* size of the widget. 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.
* @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.
* @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.
* @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.
* @snapshot: Vfunc for gtk_widget_snapshot().
* @contains: Vfunc for gtk_widget_contains().
