Custom handler for KeyboardInterrupt

[jabbson]

I am looking for a way to handle KeyboardInterrupt to gracefully shutdown the app and preserve data/progress. For example the app keeps track of events and I would like to pickle them before shutting down if the app was stopped by Ctrl-c. Is there a way to do that?

would second this, but ".quit_application()" doesn't seem to work for me at all. however letting the app populate with the default quit button and choosing that works every time, but unfortunately i have a function that is needed as part of the quit process.

rumps also seems to over ride my own signal handler.

Can't edit my above comment. rumps seems to conflict with NSWorkspace functionality from Appkit as well.
