ABSTRACT
SimpleMenu is an interface for creating application menubars in as
simple a manner as possible. Its main benifit 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 controled entierly by the path
componenets. 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::SimpleMenuFUNCTIONS
$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});
