Signal inside widget subclass

[Erick PÃrez Castellanos <erick red gmail com>]

Hi:
I have this design issue: Iâm kinda newbie with gtk development, so sorry is 
this is the first line on some mystery tutorial out there .

Iâm subclassing a Gtk.TextBuffer and I want to know inside the widget code 
when the âchangedâ signal is emitted. I know I always can connect a callback 
to the signal, that why they exist anyway, but that sound like something I 
wouldn't do inside the widget.

Is it correct ? At least from the Gtk development/design point view. It 
works, really well, my point is purely about design, maybe there a better 
and prettier way of doing this.
