<![CDATA[QGesture and QDeclarativeItem]]>Can anyone tell me if I need to do anything extra/undocumented to get a QDeclarativeItem to grab gesture events?

I am using the code described in the documentation (http://goo.gl/4Ym1R) but I just can't get any gesture events to come into the event() function.

When I ask Google for help I just get examples of people trying to do this outside QML with a standard C++ QGraphicView based app.

I wonder if QML is somehow blocking gestures?

Thanks,
Paul Drummond

Did you manage to solve your issue?

@fcrochik: a QDeclarativeItem is a QGraphicsObject subclass, so in theory grabGesture() should work there as well. Why exacly did you call those methods from the child widget and not from the QDeclarativeItem itself?

I am not sure if I tried grabGesture on the QDeclarativeItem. That is how I have it working:

My QDeclarativeItem has a QGraphicsWidget child with:

@
setAttribute(Qt::WA_AcceptTouchEvents);
grabGesture(Qt::PinchGesture);
@

and I installed an event filter on it so could process the events on my declarative item.

I am in the same situation. With simulator gestures are recongnized, but on the device (Nokia C7) aren't.
Have you managed this ?

thanks
