different position in TabAndHoldGesture and TabGesture Class

[sh033]

Hi,
I have played with the QGestureEvent, and I found the position : function in the TabAndHoldGesture and TabGesture Class is different for the same position on the screen.
Can anyone please help me to understand this

Thank you all

I think i found it.
In the source code qstandardgesture.ccp, the position of the TabGesture in line 442:

d->position = ev->touchPoints().at(0).pos();

the position of the TabAndHoldGesture in line 538:

d->position = ev->touchPoints().at(0).startScreenPos();

The TabAndHoldGesture use the ScreenPos() and the TabGesture the pos() function of the QTouchEvent Class.
I think this is a bug or not ??
