为什么，tree树形控件没有MouseEvent.RIGHT_CLICK监听事件呢？如何解决
我要实现：右键单击每一个树形控件的节点，弹出不同的操作菜单
如果可以用其他方法更好，还请指点一哈 谢谢！！

妹子，Flex里面是没有右键监听的，AIR里面有。
你这个实现有点麻烦，要不是你问问题，我真就不帮你弄了，哈哈。
看看效果：

arraycollection里面的项可以理解为object,如果你上面这个问题是指一个Arraycllection[0]做修改的话,应该就可以直接写(Arraycllection[0] as Object).lebal4="重庆"(大概这意思吧,不知道语法对不对)
