// GtkCustomMenu is a GtkMenu subclass that can contain, and collaborates with,
// GtkCustomMenuItem instances. GtkCustomMenuItem is a GtkMenuItem that can
// have buttons and other normal widgets embeded in it. GtkCustomMenu exists
// only to override most of the button/motion/move callback functions so
// that the normal GtkMenu implementation doesn't handle events related to
// GtkCustomMenuItem items.
//
// For a more through overview of this system, see the comments in
// gtk_custom_menu_item.h.
