    I found a conflict between QScroller and QScrollBar. So I have a QScrollArea with vertical scrollbar. I also activate a QScroller that allows me to do kinetic scrolling with left click button. But I can't grab the scrollbar handle any more. Because once I grab it, QScroller begins to take over. This is how I add the QScroller:

    @QScroller::grabGesture(mArea, QScroller::LeftMouseButtonGesture) ; @

    Any idea how can I solve the conflict?

      This is just a last resort, but you should be able to do QScoller::ungrabGesture() on the QScrollBar::mousePressEvent()

      Haven´t tested this though.

        It's the right way to start.
        I redefined enterEvent and leaveEvent to dis dis-activate and re-ractivate QScrollers. Works fine. Thanks.

          I would experiment with registering the QScroller not on the whole QScrollArea, but only on the client area. Or, try to use an event filter on the scrollbar.
