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.
