MapPinchEvent type provides basic information about pinch event. They are present in handlers of MapPinch (for example pinchStarted/pinchUpdated). Events are only guaranteed to be valid for the duration of the handler.
Except for the accepted property, all properties are read-only.
The following example enables the pinch gesture on a map and reacts to the finished event.
Map {
id: map
gesture.enabled: true
gesture.onPinchFinished:{
var coordinate1 = map.toCoordinate(gesture.point1)
var coordinate2 = map.toCoordinate(gesture.point2)
console.log("Pinch started at:")
console.log(" Points (" + gesture.point1.x + ", " + gesture.point1.y + ") - (" + gesture.point2.x + ", " + gesture.point2.y + ")")
console.log(" Coordinates (" + coordinate1.latitude + ", " + coordinate1.longitude + ") - (" + coordinate2.latitude + ", " + coordinate2.longitude + ")")
}
}

[read-only] point1 : QPoint |
|
[read-only] point2 : QPoint |
These read-only properties hold the actual touch points generating the pinch. The points are not in any particular order.
|
accepted : bool |
Setting this property to false in the MapPinch::onPinchStarted handler will result in no further pinch events being generated, and the gesture ignored.
|
[read-only] angle : real |
This read-only property holds the current angle between the two points in the range -180 to 180. Positive values for the angles mean counter-clockwise while negative values mean the clockwise direction. Zero degrees is at the 3 o'clock position.
|
[read-only] center : QPoint |
This read-only property holds the current center point.
|
[read-only] pointCount : int |
This read-only property holds the number of points currently touched. The MapPinch will not react until two touch points have initiated a gesture, but will remain active until all touch points have been released.
