TWaver 树节点折叠问题

[黑土墨]

当点击其他节点时，展开的节点会自动折叠，如何实现？
如下代码只能实现单击展开：

if(event is TreeEvent){//单击节点前面的“+”号展开节点。
   type = "TreeEvent";
   _treeData=(event as TreeEvent).item as TreeData;
   tempTree = event.currentTarget as Tree;
}

你好，你有TWaver.swc的开发库，能发一份到我的邮箱[e-mail]里面嘛，万分感激

         lastTreeData = _treeView.twaverTree.getTreeDataByIndex(1);

         trace("=============================" + _treeView.twaverTree.getTreeDataByIndex(1));

               if(lastTreeData != null) {
                  //判断lastTreeData和点击的节点是否为同一级别；判断lastTreeData和e.treeData是否为同一个节点，防止重复点击同一个节点后，单击该节点是总是被关闭。
                  if(lastTreeData.parent != null) {
                     if(lastTreeData.parent == e.treeData.parent && lastTreeData != e.treeData) {
