  您可以在像...这样的函数中访问页眉/页脚对象

  if(header)
          {
              var headerItem = header.createObject(null);
              // do stuff with headerItem
              headerItem.destroy();
          }
          if(footer)
          {
              var footerItem = footer.createObject(null);
              // do stuff with footerItem
              footerItem.destroy();
          }

  您应该将页眉/页脚项目分配给某个外部参考，如下所示：

  Window {
    property Item listHeaderItem: null
    Component {
      id: listHeaderComponent
      Item {
        id: headerItem
        width: listView.width; height: 0
        Component.onCompleted: rootWindow.listHeaderItem = headerItem
      }
    }
    ListView {
      header: listHeaderComponent
    }}
