MultiPointTouchArea don't work, with official example

sibislaw2

Hey, official example from http://qt-project.org/doc/qt-5/qml-qtquick-multipointtoucharea.html dont work.

Code:

@

import QtQuick 2.0

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
}

}

@

Rectangles dont change position to position touched on the touch screen.

On what platform, what device, what touchscreen?

sibislaw2

It dont work with mouse, with touchscreen it works. Topic can be closed.

But, my question is, why qt developers decided to dont handle mouse events by MultiPointTouchArea ? I have resistive laptop with single-touch and it emulates mouse, so MultiPointTouchArea dont work. I think, it should work with mouse for compatibility reasons.
