93 SimpleMenu is an interface for creating application menubars in as
94 simple a manner as possible. Its main benefit is that the menu is
95 specified as a tree, which is the natural representation of such a
96 menu.
97
99 SimpleMenu aims to simplify the design and management of a complex
100 application menu bar by allowing the structure to be specified as a
101 multi-rooted tree. Much the same functionality is provided by
102 Gtk2::ItemFactory, but the data provided as input is a 1-D array and
103 the hierarchy of the menu is controlled entirely by the path
104 components. This is not ideal when languages such as Perl provide for
105 simple nested data structures.
106 Another advantage of the SimpleMenu widget is that it simplifies the
108 creation and use of accelerators.
109 SimpleMenu is a child of Gtk2::ItemFactory, so that it may be treated
111 as such. Any method that can be called on a ItemFactory can be called
112 on a SimpleMenu.

121 $menu = Gtk2::SimpleMenu->new (menu_tree => $menu_tree, ...)
122 Creates a new Gtk2::SimpleMenu object with the specified tree.
123 Optionally key value paris providing a default_callback and
124 user_data can be provided as well. After creating the menu object
125 all of the subsequent widgets will have been created and are ready
126 for use.
127
129 $menu->{widget}
130 The Gtk2::MenuBar root of the SimpleMenu. This is what should be
131 added to the widget which will contain the SimpleMenu.
132 $container->add ($menu->{widget});
134 $menu->{accel_group}
136 The Gtk2::AccellGroup created by the menu tree. Normally
137 accell_group would be added to the main window of an application,
138 but this is only necessary if accelerators are being used in the
139 menu tree's items.
140 $win->add_accel_group ($menu->{accel_group});
