Gtk2::E...ry::Menu(3)

💖 Gtk2::Ex::FormFactory::Menu 💖

okay bestie, pull up a chair because we're talking about Gtk2::Ex::FormFactory::Menu — yes the whole thing, from the Gtk2::E...ry::Menu(3) page in the User Contributed Perl Documentation. it's a Menu living inside a FormFactory framework and honestly? she's giving organized. 🎀

🌸 NAME 🌸

Gtk2::Ex::FormFactory::Menu — a Menu in a FormFactory framework. that's it, that's the whole vibe. ✨

---

🦋 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 💅

so this class implements a Menu inside a Gtk2::Ex::FormFactory framework and it pretty much wraps Gtk2::Ex::Simple::Menu. no cap. 🫶

here's the tea though: no application object attributes are associated with a Menu as a whole. like, the menu itself? unattached. free agent. main character with no plus-one. 💀

but — and this is the good part — you can associate single Menu entries with an object. when you do, the correspondent entries will set insensitive automatically if the underlying object is undef, and vice versa, they get activated once the object is defined. it's giving "auto-pilot but make it cute". 🧚

✨ ATTRIBUTES ✨

okay so attributes are handled through the common get_ATTR(), set_ATTR() style accessors, but lowkey they're mostly passed once to the object constructor and must not be altered after the associated FormFactory was built. like, once it's built, it's built. periodt. 🙈

• 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, bestie. 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. again, refer to Gtk2::Ex::Simple::Menu for details.

for more attributes refer to Gtk2::Ex::FormFactory::Widget. 💜

and that's the whole page bestie! this was pulled from the perl v5.42.0 documentation, dated 2025-07-25, filed under Gtk2::E...ry::Menu(3). go build something gorgeous with it. mwah. 🫶💖🌸
