ABSTRACT

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

DESCRIPTION

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
107       Another advantage of the SimpleMenu widget is that it simplifies the
108       creation and use of accelerators.
109
110       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.

FUNCTIONS

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

MEMBER VARIABLES

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
133             $container->add ($menu->{widget});
134
135       $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
141             $win->add_accel_group ($menu->{accel_group});
