I have a situation where, no matter how the routine ends, I need to return the focus to a widget. It would be rather clever to do this with a context, but I would expect something like this to be a possible strategy
with contextlib.context(enter=None, exit=lambda *args: my_widget.setFocus()): do what I need to do
as far as I know, at the moment it's not possible. Am I right? I think it would be an easy and practical addition to the contextlib module to quickly register two routines for enter and exit.
with ExitStack() as stack: stack.callback(my_widget.setFocus) cm = stack.enter_context(run_your_enter_routine()) https://docs.python.org/3/library/contextlib.html#contextlib.ExitStack -- Akira
