Ok, the problems I have is that I use Gtk as an underlining widget library
for another OO Widget library (I change the hierarchy), I don't know what
calls the user are going to ask in advance, so I need to pass the signal to
the new widgets, encapsulate it in a OO virtual Method and do the call if
the user defined a method for the "event" then the code gets executed, if
not, nothing happens and the signal restarts to Gtk+, this is the reason I
want to capture all (almost all) signals, and also the reason to do it
without calling signal_connect for all signals for all widgets.

Thanks for the info and your time.

Bye.... for now...
