Create a multitouch application

[Claudia]

I'm trying to write a multitouch desktop application. I have a QML based application and now I try to drag more than one QML element at the same time. I tried to use MultiPointTouchArea, but this doesen't work. So I got 2 elements. For example 2 pictures, which should be draggable by two different persons at the same time ...
If I define a rectangle containing the MultiPointTouchArea and I link one touchPoint with each picture, the first touch event moves the first picture and the second touch event moves the second picture.

Like in this example code:

@Rectangle {
width: 400; height: 400
MultiPointTouchArea {
anchors.fill: parent
touchPoints: [
TouchPoint { id: point1 },
TouchPoint { id: point2 }
]
}

    Rectangle {
        width: 30; height: 30
        color: "green"
        x: point1.x
        y: point1.y
    }

    Rectangle {
        width: 30; height: 30
        color: "yellow"
        x: point2.x
        y: point2.y
    }
}@

This is not, what I'm looking for. I want them to move, if they are touched and dragged, both at the same time, without disturbing each other and without a order of touch events.

Is this possible in qml? Or do I have to code a C++ function?

I hope you understand my problem.
