flex 展开树的指定节点

　　思路: 要展开某个指定节点 ，须要从根节点一步步展开到指定节点： function expandParents(node:XML):void { if (node && !templateTree.isItemOpen(node)) { templateTree.expandItem(node, true); expandParents(node.parent()); } } ; //展开tree expandParents((item as XML));//具体展开的代码 templateTree.selectedItem = item; 也可保存路径: var parentArray:Array = new Array(); var obj:Object = currentSelectedTreeNode.parent; while( obj ) { try { obj = obj.parent; parentArray.push( obj ); } catch( e:Error ) { break; } } http://www.flexdeveloper.eu/forums/flex-charting/t ree-control-how-to-get-the-full-path-of-selectedite m-in-tree-control/
