Feature? - register callback to the QuitEvent

[jlp765]

Is there already a way to have a callback proc called on the QuitEvent
so that the quit can be intercepted, and

• the user asked if they want to quit (and a mechanism to stop the QuitEvent propagating)
• do some clean up, etc (although this could be done by the exitprocs.addExitProc)

There's no such thing iirc. If you're into implementing it, I'd suggest doing this API by adding shouldExit*: proc(): bool to Application.
