6 Gtk2::Ex::FormFactory::Menu - A Menu in a FormFactory framework

9 Gtk2::Ex::FormFactory::Menu->new (
10 menu_tree => Hierarchical definition of the Menu,
11 default_callback => Default callback for menu items,
12 user_data => User data for the default callback,
13 ...
14 Gtk2::Ex::FormFactory::Widget attributes
15 );
16
18 This class implements a Menu in a Gtk2::Ex::FormFactory framework and
19 pretty much wraps Gtk2::Ex::Simple::Menu. No application object
20 attributes are associated with a Menu as a whole.
21
22 But you may associate single Menu entries with an object. This way the
23 correspondent entries will set insensitive automatically if the
24 underlying object is undef and vice versa are activated once the object
25 is defined.

37
39 Attributes are handled through the common get_ATTR(), set_ATTR() style
40 accessors, but they are mostly passed once to the object constructor
41 and must not be altered after the associated FormFactory was built.
42
43 menu_tree = ARRAYREF [mandatory]
44 This is a slightly extended menu tree definition in terms of
45 Gtk2::Ex::Simple::Menu. You may optionally associate each entry
46 with an application object by specifying its name with the object
47 key in the item definition hash. This way the item is active only
48 if the correspondent object is defined.
49
50 As well you can control widget activity more detailed using the
51 active_cond and active_depends keys as described in the
52 Gtk2::Ex::FormFactory::Widget manpage.
53
54 A short example. This is a File menu where the 'Save' and 'Close'
55 entries are sensitive only if a file was opened. We presume that
56 opening a file sets the 'worksheet' object, which is registered
57 with this name to the Context of the associated FormFactory.
58 Additionally the 'Manage rows' entry is active only if more than
59 three rows are selected:
60
61 $menu_tree = [
62 _File => {
63 item_type => <Branch>',
64 children => [
65 _Open => {
66 callback => \&open_worksheet,
67 # sets the 'worksheet' object
68 },
69 _Save => {
70 callback => \&save_worksheet,
71 object => 'worksheet',
72 },
73 _Close => {
74 callback => \&close_worksheet,
75 object => 'worksheet',
76 },
77 "_Manage rows" => {
78 callback => \&manage_rows,
79 object => 'worksheet',
80 active_cond => sub { $worksheet->get_selected_rows_cnt > 3 },
81 active_depends => "worksheet.rows",
82 ],
83 },
84 ];
85
86 default_callback = CODEREF [optional]
87 The default callback of this menu. Refer to Gtk2::Ex::Simple::Menu
88 for details.
89
90 user_data = SCALAR [optional]
91 User data of the default callback of this menu. Refer to
92 Gtk2::Ex::Simple::Menu for details.
93
94 For more attributes refer to Gtk2::Ex::FormFactory::Widget.
