Qt: change color on dragging curve

[bchinfosieeuw]

I can put a bezier curve on a MouseArea on mouseclick. I can even drag and drop it. But how can I change the color of the curve while dragging it? My code:

Item {
    Path {
        id: mycurve
        startX: -132; startY: -12
        PathCurve { x: -138; y: -14 }
        PathCurve { x: -140; y: -20 }
        PathCurve { x: -146; y: -22 }
    }
    Rectangle {
        id: rect
        width: 2
        height: 2
        color: "black"
        border.color: "black"


    MouseArea {
        anchors.fill: parent
        acceptedButtons:  Qt.LeftButton | Qt.RightButton
        onPressed: {mycurve.color = "red";}//what should I do here?
        onReleased: {mycurve.color = "black";}//what should I do here?
        onPositionChanged: {
            if (mouse.buttons & Qt.LeftButton) {
                mycurve.x -= (x - mouse.x); mycurve.y = (y - mouse.y); ;
            }

        }
    }
    PathView {
            id: pathView1;
            x: 158
            width: 708
            model: 300;
            path: mycurve
            delegate: Rectangle {
                id: dot;
                width: 1; height: 1;
                color: "black"
                ColorAnimation on color { to: "red"; duration: 0 }//my own attempt
            }
    }
    }
}
