(checking return value of sscanf() ??) that's the best i know of. some people have tried to write validating widgets. my impression is that none of them have been particular generic. you can also handle the key_press/release events and disallow (by returning TRUE) the normal entry of "illegal" keys. --p _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
