/**
 * Description
 * GtkWidget is the base class all widgets in GTK+ derive from. It manages the
 * widget lifecycle, states and style.
 * GtkWidget introduces style
 * properties - these are basically object properties that are stored
 * not on the object, but in the style object associated to the widget. Style
 * properties are set in resource files.
 * This mechanism is used for configuring such things as the location of the
 * scrollbar arrows through the theme, giving theme authors more control over the
 * look of applications without the need to write a theme engine in C.
 * Use gtk_widget_class_install_style_property() to install style properties for
 * a widget class, gtk_widget_class_find_style_property() or
 * gtk_widget_class_list_style_properties() to get information about existing
 * style properties and gtk_widget_style_get_property(), gtk_widget_style_get() or
 * gtk_widget_style_get_valist() to obtain the value of a style property.
 * <hr>
 * GtkWidget as GtkBuildable
 * The GtkWidget implementation of the GtkBuildable interface supports a
 * custom <accelerator> element, which has attributes named key,
 * modifiers and signal and allows to specify accelerators.
 * $(DDOC_COMMENT example)
 * In addition to accelerators, GtkWidget also support a
 * custom <accessible> element, which supports actions and relations.
 * Properties on the accessible implementation of an object can be set by accessing the
 * internal child "accessible" of a GtkWidget.
 * $(DDOC_COMMENT example)
