I'm not sure I follow your code but this method is bound to the
<Configure> event *but* needs to return the string "break" so that it
does not pass that event on to the default event handler.



      def changed(self, ev):
          w, h = self.winfo_reqwidth(), self.winfo_reqheight()
          cfg = {}
          if ev.height > h:
              cfg['height'] = h
          if ev.width > w:
              cfg['width'] = w
          if cfg:
              self.config(**cfg)   ######## this has no effect ########
          return "break"

This may do what you want.....
