No, thats not correct. You dont need a toplevel widget (at least not with
glade 0.5.11). YOu only need a widget inside the toplevel widget.

  wanted_widget = lookup_widget(any_widget_inside_Haupt, "name_of_wanted_widget");

lookup_widget() traces to the toplevel widget and does a
gtk_object_get_data(top_level_object, "name_of_wanted_widget");
