There are no such default signal handler virtual functions in the maaemo
version of gtkmm:

You probably need to connect "after":
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/sec-xeventsignals.html

Note that you can only use add_events() after the widget has been
realized. For instance, in a signal_realize signal handler.
