Calling get_parent() on a Gtk submenu (item) does not yield its parent menu but rather the object it extends from. Is it possible to identify the parent menu?
I need it for a much more complex menu structure than the one below MCVE, in order to toggle the RadioMenuItem checkboxes of the above-lying menuitems.
menu = Gtk.Menu()
menu_item = Gtk.MenuItem('blah', 'blah')
menu_item.set_submenu(create_submenu())
menu.append(menu_item)
def create_submenu():
submenu = Gtk.Menu()
submenu_item = Gtk.MenuItem('blah', 'blah')
submenu.connect('activate', do_something)
submenu.append(submenu_item)
return submenu
def do_something(widget):
widget.get_parent().set_label('this is not the parent menu') # <--- refers to Gtk.Window, not our menu above
As mentioned in the comments by Edouard Thiel, you can indeed run submenu.get_parent().get_attach_widget() to receive a reference to the parent menu. More info at https://people.debian.org/~osamu/gtk3tutor/python-gtk3/Gtk.Menu.get_attach_widget.page
