I haven't actually tried your code, but this might be the problem here: > def _select1(self): > if self.fila==self.size()-1: > pass > else: > self.selection_clear(0, END) > self.selection_set(self.fila+1) > self.fila+=1 > self._scroll() > return 'break' > > def _scroll(self, *args): > for l in self.lists: > apply(l.yview, args) You call self._scroll with no arguments to make the selected index visible (I guess). But self._scroll just calls yview on each list..and yview with no arguments returns a tuple, but otherwise does nothing. Try replacing self._scroll with self.see --- possibly: self.see(self.fila). -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
