    visible: true

    Rectangle {
        width: 100
        height: 100
        color: "green"

        // Oops, we tried to shadow a FINAL property from QQuickRectangle:
        // Q_PROPERTY(qreal topLeftRadius READ topLeftRadius WRITE setTopLeftRadius NOTIFY topLeftRadiusChanged RESET resetTopLeftRadius REVISION(6, 7) FINAL)
        property real topLeftRadius: 50 
    }
