tkinter: wait_variable

[Bob van der Poel]

How does wait_variable() work? I've got the following in a class:

	__marked = []

	....

	def mark(self):
		a callback to mark certain items
		self.__marked.append(x)

	def wait(self, root):
		root.wait_variable(self.__marked)
		return self.__marked


and I call it, after setting up,etc:

	print myclass.wait(root)

However, it never seems to return. With test print statements I have
determined that my __marked variable is being updated...but
wait_variable() doesn't seem to sense it.
