You may want a timer to be able to do some cleanup after the window closes, so if the timer is running a process which doesn't need to finish if the window closes you want to manually stop it in the window close event process.

     Could you elaborate on "not recommended?"  For my own applications,
EXIT_ON_CLOSE is the option I use most frequently. The next is
DO_NOTHING_ON_CLOSE with a WindowAdapter for window-closing events;
both stratagems seem unobjectionable to me.

     A method to stop all timers sounds about as useful as a method
to stop all threads -- that is to say, more perilous than useful.
