*all* signal handlers for signals that have a non-void return type must return TRUE or FALSE to indicate whether or not they have handled the signal. its up to the handler code to decide what "handled" might mean, given the following awareness of what their return value will mean: if they return TRUE, then generally other handlers that were connected later will not be called. if they return FALSE, the other handlers will be called. the way this all works is a bit muddied in GTK+ 1.2; it appears to be much cleaner in GTK+ 1.3/2.0. --p _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
