I think one ought to try it out ;) I don't think that a connected signal
overrides the default one - the default handler will be called unless it
is stopped (perhaps gtk_signal_emit_stop() or gtk_signal_handler_block()
would help here, but I'm not sure - somebody correct me if I'm getting
it all wrong). In general there is quite a number of features in GTK
that I only have a vague idea of what they do and how should they be
used. Some good documentation would help enormously here since reading a
lot of somebody else's source really puts me off.
