QScroller vs mouseReleaseEvent, quite trigger happy

Hi,

i am making an mobile app that has a QScrollArea where i enable finger swipe scrolling like this:

QScroller::grabGesture(ui->scrollArea, QScroller::LeftMouseButtonGesture);

Within this Scrollarea there are Widgets that so stuff when their mouseReleaseEvent is triggered.

The scroll area is quite big, so there is quite some way you can scroll... If i now scroll with the finger, everything is as i want it: Even if i start the swipe over one of the objects reacting to the mouseReleaseEvent, the objects itself do not receive the mouseReleaseEvent.

But once the scrolling startet occasionally any further swipe triggers a mouseReleaseEvent on the widgets in the ScrollArea.

Is there any way to prevent this? Is it a Qt bug that will be fixed? Or do i have to reimplement QScroller myself?

Kind regards,
Heiko
