qml Property binding A more complicated example


In the simple example, we simply set the width of the rectangle to that of it's parent. Let's consider a more complicated example:

ApplicationWindow {
    visible: true
    width: 400
    height: 640

        id: rect
        anchors.centerIn: parent
        height: 100
        width: parent.width/2 + parent.width/3
        color: "blue"

In the example, we perform arithmetic operation on the value being binded. If you resize the running application window to maximum width, the gap between the rectangle and the application window will be wider and vice-versa.
