Description

Currently, when a main window in a highgui application is closed, the programs usually go to a deadlock state and needs to be canceled by pressing Ctrl-C, etc. It would be nice if we allow the users to detect closure of windows(and/or disable it) and then handle the window closure by gracefully exiting the program.

This should be easy to implement because all major window systems have these callbacks.

I can volunteer to implement this if you assign me.
