I did winEventFilter because I found more helpful sample code related to winEventFilter. I am not a QT specialist so I don't know the difference between those two.

Ok. Fully understood.
The QApplication is more global that the QWidget one. After thinking a
bit, you are right, the Application one is better, because it can solve
corner cases (should work for all dialogs... in this way).

However, I don't like this solution because you subclass the
QApplication for Win32 and not for x11... I would have prefer creating a
QVLCApplication and override only on win32 the winEventFilter...
