      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
              }
          }
      }
