ABSTRACT
SimpleMenu is an interface for creating application menubars in as simple a manner as possible. Its main benefit is that the menu is specified as a tree, which is the natural representation of such a menu.

DESCRIPTION
SimpleMenu aims to simplify the design and management of a complex application menu bar by allowing the structure to be specified as a multi-rooted tree. Much the same functionality is provided by Gtk2::ItemFactory, but the data provided as input is a 1-D array and the hierarchy of the menu is controlled entirely by the path components. This is not ideal when languages such as Perl provide for simple nested data structures.

Another advantage of the SimpleMenu widget is that it simplifies the creation and use of accelerators.

SimpleMenu is a child of Gtk2::ItemFactory, so that it may be treated as such. Any method that can be called on a ItemFactory can be called on a SimpleMenu.

OBJECT HIERARCHY
 Glib::Object
 +--- Gtk2::Object
      +--- Gtk2::ItemFactory
           +--- Gtk2::SimpleMenu

FUNCTIONS

$menu = Gtk2::SimpleMenu->new (menu_tree => $menu_tree, ...)
    Creates a new Gtk2::SimpleMenu object with the specified tree. Optionally key value paris providing a default_callback and user_data can be provided as well. After creating the menu object all of the subsequent widgets will have been created and are ready for use.

MEMBER VARIABLES

$menu->{widget}
    The Gtk2::MenuBar root of the SimpleMenu. This is what should be added to the widget which will contain the SimpleMenu.

      $container->add ($menu->{widget});

$menu->{accel_group}
    The Gtk2::AccellGroup created by the menu tree. Normally accell_group would be added to the main window of an application, but this is only necessary if accelerators are being used in the menu tree's items.

      $win->add_accel_group ($menu->{accel_group});
