Description
   
    A GtkMenuBar is a container that exclusively holds
    GtkMenuItem widgets, and displays them from left
    to right.
   
   
    It has key bindings which allow the Up, 
    Down, Left 
    and Right arrow keys to be used for menubar
    navigation. Note that these do not work in the win32 version of
    GTK+ used by PHP-GTK.
   
   
    A menu bar with a number of subitems can be easily created with
    the GtkItemFactory class.
