Hi,

I’m being faced with a situation where a custom knob is layed out inside nested 
flickables. 

My custom knob touch handling is made with a MultiPointTouchArea to allow 
multiple knob interactions.

To avoid the gesture being grabbed by the flickables where is layed into, I 
call gesture.grab() onGestureStarted.

The problem is that, when the touch terminates, it isn’t released unless I tap 
in another element outside. 

If I don’t do that, the gesture will keep assigned to that particular knob and 
this is an awkward and not welcome behaviour.

I couldn’t find a gesture release on documentation. Maybe i’m missing something 
here.

Does anyone has a clue on how to avoid this problem?

Thanks in advance.

Regards,

Nuno Santos
