        # Next we make a little loop that makes three menu-entries for
        # "test-menu".  Notice the call to gtk_menu_append.  Here we are
        # adding a list of menu items to our menu.  Normally, we'd also
        # catch the "clicked" signal on each of the menu items and setup a
        # callback for it, but it's omitted here to save space.

            # Show the widget

        # as it only pops up the rest of the menu when pressed.

        # Now we specify that we want our newly created "menu" to be the
        # menu for the "root menu"

        # A vbox to put a menu and a button in:
        vbox = gtk.VBox(False, 0)

        button.connect_object("event", self.button_press, menu)
        vbox.pack_end(button, True, True, 2)

        # And finally we append the menu-item to the menu-bar -- this is the
        # "root" menu-item I have been raving about =)

        # the screen at once.
