Re: [Pythoncard-users] Creating dynamic window

[John H. <ec...@ya...>]

Oh, silly me.  Control_factory can be further
simplied:

def Control_factory(self, attribute, eventHandlers):
	name=attribute['name']
	for eventName in eventHandlers.keys():
		eventFct=eventHandlers[eventName]
		def function(self, background, event):
			if eventFct==None:
				return None
			return eventFct(self, event)
		function.name = "on_%s_%s" % (name,eventName)
		method = new.instancemethod(function, self,
self.__class__)
		setattr(self, function.name, method)
		self.addHandler(method)
	self.components[name] = attribute
	return function
