    Description

      With the code below, press the space key to change orientation. Observe the yellow square is not re-positioned correctly. This is because the delegate item has already been created internally and the item's previous y (which was defined while in the vertical orientation) is used for the new orientation.

      import QtQuick 2.0

Item {
    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: "green" }
        }

        focus: true

        Keys.onSpacePressed: {
            orientation = Qt.Horizontal
        }
    }
}
