Description
   
    GtkMenu is a menushell widget, designed
    to exclusively hold GtkMenuItems.  It may be a
    standalone popup widget, or may be associated either with a higher-level 
    GtkMenuItem within a 
    GtkMenuBar, or with a 
    GtkOptionMenu.
   
   
    Note that a GtkMenu in any form is effectively a
    modal popup widget.  There are keybindings in place here specifically to
    counteract this apparent isolation, by allowing the 
    Up, Down, Left 
    and Right arrow keys to navigate multiple menus with
    regard to the relationships between those menus (i.e. parent and child, 
    next and previous).  These are fairly rudimentary in the current version
    of GTK+ used in PHP-GTK, but have been improved recently.
