Actually, I just found a better solution:
def render(self, size, focus=False):
if focus:
self.toolbar.set_text(self.tip)
canv = super(EditWithTip, self).render(size, focus)
Render gets called all the time for the object, but focus is only True if
it's in focus. It's good enough for my needs and I don't need to handle
ListBox indexes and check positions. I just want to be able to add
tooltip-enhanced Edits arbitrarily anywhere and not have to track it or
store tooltip strings separately.
