Re: how to connect Gio::SimpleAction signal

[Kjell Ahlstedt <kjellahlstedt gmail com>]

If your menu is not a window menu or application menu, the prefix can 
something else, not necessarily win or app. Comparing your code with 
https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/menus/popup?h=gtkmm-3-22 
I see that you have not called Gtk::Widget::insert_action_group(). An 
example:

insert_action_group("myactiongroup", act_group);

Then the call to giomenu->append() should be

giomenu->append("THIRD", "myactiongroup.THIRD");
