There are plans to have to native gesture support on hardware and OS 
that support it (and 'native' means gestures that come from the 
underlaying system - currently this is limited to Windows7 and Mac OS X 
10.6).

However on platforms that just have multitouch hardware, it might be 
possible to get touch events (see QTouchEvent) and gestures (QGesture - 
right it there is a QPanGesture, but plans to have QPinchGesture as 
well) by feeding Qt with low-level touch information manually.
