[IronPython] How to make a gtk event?

[Martin Matusiak]

Yes, that works. But pedantically speaking, is it possible to
manufacture an event that would agree on type with the gtk produced
ones? I really don't know if this ever comes up but suppose at one
point it needs to be interchangeable with a built in event?
