Well, I would use the response ID approach.  It simplifies things a lot
-- if your dialog has more than 2 or 3 buttons in the action area it's
probably broken UI wise anyway.

Barnaby, most of the time you will use the predefined response IDs in
gtkmm, e.g. Gtk::RESPONSE_OK.  If you really need your own IDs just use
an anonymous enum -- the builtin ones are all < 0 so that won't clash.
