-// 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.
