Re: about callback for GtkItemfactory

["Donna S. Martin" <donna omartin com>]

If you are "manually" connecting the signal with
gtk_signal_connect() you use the signal
prototype, i.e.  void handler(GtkWidget *widget,gpointer callback_data);

If you use the ItemFactory facility for attaching  callbacks,
 then you use the ItemFactory prototype .

So, in  your case, you use the activate signal prototype because you
are doing the gtk_signal_connect() yourself.

HTH,
Donna
