QDial unresponsive - disable gesture recognition?

[AndreasBuhr]

Hi,

I do have an app for Android with a QDial control. I'd like the app to immediately react on changes at the QDial. The QDial reacts immediately on touching it (that's good). However, its reaction to dragging the finger on the screen is strongly delayed, it feels very unresponsive. I suspect the gesture recognition to be the reason, but this is only speculation.

Does anyone know this effect of unresponsive controls on Android?
Is there a way to solve this?
Is there a way to disable gesture recognition?

I already tried unregistering all gesture recognizers by:

@
QGestureRecognizer::unregisterRecognizer(Qt::TapGesture);
QGestureRecognizer::unregisterRecognizer(Qt::TapAndHoldGesture);
QGestureRecognizer::unregisterRecognizer(Qt::PanGesture);
QGestureRecognizer::unregisterRecognizer(Qt::PinchGesture);
QGestureRecognizer::unregisterRecognizer(Qt::SwipeGesture);
@

But this did not help.

Thanks a lot and best

It seems to be unrelated to gesture recognition. I now created a bug report for this:
