\par
When the user presses Cmd-Q or requests a termination of the
application, OS X will send a "Quit" Apple Event. FLTK handles
this event by sending an \c FL_CLOSE event to all open
windows. If all windows close, the application will terminate.
application, FLTK reacts sending an \c FL_CLOSE event to all open
windows. If any window remains open, the termination request aborts.
If all windows close, the application's event loop terminates,
that is, Fl::run() returns. The application can then follow
FLTK's normal termination path executing cleanup code that may be programmed
after termination of the event loop, and returning from main().
Function Fl::run_also_windowless() can be used instead of Fl::run() to keep
the event loop running also after all windows are closed, a feature the MacOS platform supports.
This function also returns after a successful Cmd-Q.
Function Fl::program_should_quit() allows to detect whether the event loop
terminated because of a program termination request.
