    id: root

    property real panelSize: 150

    width: 200; height: 200

    ListView {
        width: 200; height: 200

        model: VisualItemModel {
            Rectangle { width: root.panelSize; height: root.panelSize; color: "red" }
            Rectangle { width: root.panelSize; height: root.panelSize; color: "yellow" }
            Rectangle { width: root.panelSize; height: root.panelSize; color: "blue" }
        }
