 * A #GtkMenuToolButton is a #GtkToolItem that contains a button and

 * 
 * The GtkMenuToolButton implementation of the GtkBuildable interface

 * of a <child> element.

 * An example for a UI definition fragment with menus:
 * |[
 * <object class="GtkMenuToolButton">
 * <child type="menu">
 * <object class="GtkMenu"/>
