PassEventsUp

PassEventsUp
is an option to EventHandler which specifies whether events handled by a particular event handler should be passed up to event handlers in outer expressions.

MORE INFORMATION

Possible settings are:

	True	pass all events up
	False	pass no events up
	Automatic	pass events up if their action does not evaluate to False
