Some properties, methods, and attributes of GObject.Objects are overridden to make declarative UI construction easier and reduce boilerplate.

Gio.Menu and Gio.MenuItem

Before

local menu = Gio.Menu()

local item = Gio.MenuItem()
item:set_label('option 1')
item:set_detailed_action('action()')

local submenu = Gio.Menu()

local submenu_item = Gio.MenuItem()
submenu_item:set_label('submenu')
submenu_item:set_submenu(submenu)

menu:append_item(item)
menu:append_item(submenu_item)

After

local menu = Gio.Menu {
    Gio.MenuItem {
        label = 'option 1',
        action = 'action()',
    },
    Gio.MenuItem {
        label = 'submenu',

        -- Same as:
        -- submenu = Gio.Menu { ... }

        Gio.Menu {},
    },
}
