Re: How do I redispatch event?

Thanks for the response.  Here's the code that works
the best (not perfect):

	def on_field1_gainFocus(self, event):
		event.target.size=(160,event.target.size[1])
		event.target.redraw()
		event.skip(True)
		return
	
	def on_field1_select(self, event):
		event.target.size=event.target.userdata
		event.target.redraw()
		event.skip(True)
		return

where userdata contains the original size of the
field.

The above works good enough but not perfect.  You know
how when you click a normal combo box and the
selection list pulls down?  Well, with the above, the
first time I click on that arrow, the combo box
widens.  Then I have to click it a second time for the
selection list to pull down.
