By default if the gesture is ignored, only gestures in the started state are propagated, and accepting a gesture in the started state adds an implicit grab meaning all the following events in the gesture sequence will be delivered to that widget. This is similar to the way QTouchEvent is propagated. Also added a hint, which specifies if gestures in any state can be propagated to the widget which has enabled the hint.
