GtkMenu::get_accel_group
get_accel_group() returns the
global accelerator group that is used in the calling
GtkMenu.
Note that this method does not work as it should in the win32 version
of GTK+ currently used by PHP-GTK. Also, much of the accelerator
lock mechanism has been replaced in GTK2. Future-friendly code can be
created by using GtkItemFactory to create your
menus; however, the same limitations in functionality currently apply.
