Well, reference counters aside, I would much appreciate a (preferably
type-safe) way to obtain either a pointer or a Glib::RefPtr to the
Gtk::Action. The get_object is not template-based and returns a
GLib::RefPtr<Glib::Object> and I don't know how to convert this to a
Gtk::Action* or GLib::RefPtr<Gtk::Action>.
If Gtk::Actions and Gtk::ActionGroups are available in glade, they
should be usable from the underlying code. Could anyone please point me
in the right direction here? I have already looked through many of the
links to programs using gtk3mm, but so far I have found nothing.
