SYNOPSIS
Gtk2::Ex::FormFactory::Menu->new (
menu_tree => Hierarchical definition of the Menu,
default_callback => Default callback for menu items,
user_data => User data for the default callback,
...
Gtk2::Ex::FormFactory::Widget attributes
);
DESCRIPTION
This class implements a Menu in a Gtk2::Ex::FormFactory framework and
pretty much wraps Gtk2::Ex::Simple::Menu. No application object
attributes are associated with a Menu as a whole.
But you may associate single Menu entries with an object. This way the
correspondent entries will set insensitive automatically if the
underlying object is undef and vice versa are activated once the object
is defined.
OBJECT HIERARCHY
Gtk2::Ex::FormFactory::Intro
Gtk2::Ex::FormFactory::Widget
+--- Gtk2::Ex::FormFactory::Menu
Gtk2::Ex::FormFactory::Layout
Gtk2::Ex::FormFactory::Rules
Gtk2::Ex::FormFactory::Context
Gtk2::Ex::FormFactory::Proxy
ATTRIBUTES
Attributes are handled through the common get_ATTR(), set_ATTR() style
accessors, but they are mostly passed once to the object constructor
and must not be altered after the associated FormFactory was built.
menu_tree = ARRAYREF [mandatory]
This is a slightly extended menu tree definition in terms of
Gtk2::Ex::Simple::Menu. You may optionally associate each entry
with an application object by specifying its name with the object
key in the item definition hash. This way the item is active only
if the correspondent object is defined.
As well you can control widget activity more detailed using the
active_cond and active_depends keys as described in the
Gtk2::Ex::FormFactory::Widget manpage.
A short example. This is a File menu where the 'Save' and 'Close'
entries are sensitive only if a file was opened. We presume that
opening a file sets the 'worksheet' object, which is registered
with this name to the Context of the associated FormFactory.
Additionally the 'Manage rows' entry is active only if more than
three rows are selected:
$menu_tree = [
_File => {
item_type => <Branch>',
children => [
_Open => {
callback => \&open_worksheet,
# sets the 'worksheet' object
},
_Save => {
callback => \&save_worksheet,
object => 'worksheet',
},
_Close => {
callback => \&close_worksheet,
object => 'worksheet',
},
"_Manage rows" => {
callback => \&manage_rows,
object => 'worksheet',
active_cond => sub { $worksheet->get_selected_rows_cnt > 3 },
active_depends => "worksheet.rows",
],
},
];
default_callback = CODEREF [optional]
The default callback of this menu. Refer to Gtk2::Ex::Simple::Menu
for details.
user_data = SCALAR [optional]
User data of the default callback of this menu. Refer to
Gtk2::Ex::Simple::Menu for details.
For more attributes refer to Gtk2::Ex::FormFactory::Widget.
