QML PinchEvent Element

Setting this property to false in the PinchArea::onPinchStarted handler will result in no further pinch events being generated, and the gesture ignored.

These properties hold the angle between the two touch points.

• angle is the current angle between the two points in the range -180 to 180.
• previousAngle is the angle of the previous event.
• rotation is the total rotation since the pinch gesture started.

When a pinch gesture is started, the rotation is 0.0.

These properties hold the position of the center point between the two touch points.

• center is the current center point
• previousCenter is the center point of the previous event.
• startCenter is the center point when the gesture began

These properties provide the actual touch points generating the pinch.

• point1 and point2 hold the current positions of the points.
• startPoint1 and startPoint2 hold the positions of the points when the second point was touched.

Holds the number of points currently touched. The PinchArea will not react until two touch points have initited a gesture, but will remain active until all touch points have been released.

These properties hold the scale factor determined by the change in distance between the two touch points.

• scale is the current scale factor.
• previousScale is the scale factor of the previous event.

When a pinch gesture is started, the scale is 1.0.
