#warning XEventNotifier needs porting to QAbstractNativeEventFilter [-Wcpp]

for this I think I've to re write this XEventNotifier class with QAbstractNativeEventFilter as base class and re-implementing its only vortual function, but I have no idea about what XEventNotifier does.
If you are having any clues about this class and how to port it, I would be obliged to hear the solution.

cheers !

Thanks
