Re: Using Gtk.Builder to create a menubar.

[Luca Bacci <luca bacci982 gmail com>]

Hi, I did test it out, here's a working version:

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
from gi.repository import Gio

class Window(Gtk.ApplicationWindow):
    def __init__(self):
        Gtk.Window.__init__(self)
        self.set_default_size(200, 100)

        #
        self.interface_info = """
        <interface>
          <menu id='TheMenuModel'>
            <submenu>
              <attribute name='label'>Foo</attribute>
              <item>
                <attribute name='label'>Bar</attribute>
                <attribute name='action'>win.bar</attribute>
              </item>
            </submenu>
          </menu>
        </interface>
        """

        builder = Gtk.Builder.new_from_string(self.interface_info, -1)

        action_bar = Gio.SimpleAction.new('bar', None)
        action_bar.connect('activate', self.on_menu)
        self.add_action(action_bar)

        menumodel = builder.get_object('TheMenuModel')
        menubar = Gtk.MenuBar.new_from_model(menumodel)

        # layout
        self.layout = Gtk.Box(orientation=Gtk.Orientation.VERTICAL)
        self.layout.pack_start(menubar, False, False, 0)
        self.add(self.layout)

        self.connect('destroy', Gtk.main_quit)
        self.show_all()

    def on_menu(self, action, value):
        print('on_menu')

if __name__ == '__main__':
    win = Window()
    Gtk.main()
