Is there an example somewhere that shows how I can combine the `void on_menu_mode_*()` member functions of a widget that is not derived (indirectly) from Gio::ActionMap to the menu of the window that this widgets belongs to? Thanks, Carlo Wood
I think that's what you can do. Create a Gio::SimpleActionGroup.
Add your actions to it. Insert it in your widget with
Gtk::Widget's insert_action_group() method. In the call to
insert_action_group() you choose what prefix to use in the ui
file.
