def relay_events_from(self, originator, event_type, *more_event_types):
handlers = {<EOL>event_type: lambda *args, **kwargs:self.dispatch_event(event_type, *args, **kwargs)<EOL>for event_type in (event_type,) + more_event_types<EOL>}<EOL>originator.set_handlers(**handlers)<EOL>
Configure this handler to re-dispatch events from another handler.

This method configures this handler dispatch an event of type 
*event_type* whenever *originator* dispatches events of the same type 
or any of the types in *more_event_types*.  Any arguments passed to the 
original event are copied to the new event.

This method is mean to be useful for creating composite widgets that 
want to present a simple API by making it seem like the events being 
generated by their children are actually coming from them.  See the 
`/composing_widgets` tutorial for an example.
