Hello,
once again, I am stuck on a problem...

Can anybody tell me what happens exactly when the user clicks the window
managers close button? And, especially, what is the difference than
calling app->quit()? All I want to do is make sure a slot is called when
this close button is hit. 
The lastWindowClosed signal did not make it.
Greetings,
--Mirko.
