If you are using the loop for a reason, ie you have multiple threads
with sigs & slots needing the loop for their execution, or events going
on...  Then simply call qApp->quit or connect a singal to it, since quit
is a slot.

BTW.. that's essentially how a windowed based env works, a window
manager keeps track of all windows and when the last one is closed, a
signal is emmited that is connected to quit.

BTW.. if your not using a GUI, use QCoreApplication
