## Property Documentation

### horizontalDirection : const SwipeDirection

This property holds the horizontal direction of the gesture.

If the gesture has a horizontal component, the horizontal direction is either Left or Right; otherwise, it is NoDirection.

Access functions:

SwipeDirection | horizontalDirection () const

### swipeAngle : qreal

This property holds the angle of the motion associated with the gesture.

If the gesture has either a horizontal or vertical component, the swipe angle describes the angle between the direction of motion and the x-axis as defined using the standard widget coordinate system.

Access functions:

qreal | swipeAngle () const
void | setSwipeAngle ( qreal value )
