SlideBar handle from center QML
<p>In slidebar in qml the slide starts from the start. Is there any way we could specify like to make it start from the center. Like when dragging to left it should show the color. just like having a negative slider</p>

<p>I tried out something like this but For me it(orange progress) should start from the center and propagate left and right from the center like a balance bar.</p>

<pre><code>import QtQuick 2.0
import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.4

Item {
    Slider {
        anchors.centerIn: parent
        value: 0.5
        width: 400
        style: SliderStyle {
            groove: Rectangle {
                implicitHeight: 2
                color: "lightgrey"
                radius: 3

                Rectangle {
                    implicitHeight: 2
                    color: "orange"
                    radius: 3
                    implicitWidth: control.value * parent.width

                }
            }             
        }
    }
}
