Constructor & Destructor Documentation

◆ QQuickPinch()

QT_BEGIN_NAMESPACE QQuickPinch::QQuickPinch ( )

\qmltype PinchEvent \instantiates QQuickPinchEvent \inqmlmodule QtQuick

For specifying information about a pinch event.

{The PinchEvent type was added in QtQuick 1.1}

The center, startCenter, previousCenter properties provide the center position between the two touch points.

The scale and previousScale properties provide the scale factor.

The angle, previousAngle and rotation properties provide the angle between the two points and the amount of rotation.

The point1, point2, startPoint1, startPoint2 properties provide the positions of the touch points.

The accepted property may be set to false in the onPinchStarted handler if the gesture should not be handled.

See also: PinchArea

\qmlproperty QPointF QtQuick::PinchEvent::center \qmlproperty QPointF QtQuick::PinchEvent::startCenter \qmlproperty QPointF QtQuick::PinchEvent::previousCenter

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

\list

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

\qmlproperty real QtQuick::PinchEvent::scale \qmlproperty real QtQuick::PinchEvent::previousScale

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

\list

scale is the current scale factor.
previousScale is the scale factor of the previous event. \endlist

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

\qmlproperty real QtQuick::PinchEvent::angle \qmlproperty real QtQuick::PinchEvent::previousAngle \qmlproperty real QtQuick::PinchEvent::rotation

These properties hold the angle between the two touch points.

\list

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. \endlist

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

\qmlproperty QPointF QtQuick::PinchEvent::point1 \qmlproperty QPointF QtQuick::PinchEvent::startPoint1 \qmlproperty QPointF QtQuick::PinchEvent::point2 \qmlproperty QPointF QtQuick::PinchEvent::startPoint2

These properties provide the actual touch points generating the pinch.

\list

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. \endlist

\qmlproperty bool QtQuick::PinchEvent::accepted

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

\qmlproperty int QtQuick::PinchEvent::pointCount

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.
