1. 设计目标:png-1163

Flex中Tree动态加载,即在点击之后才加载下级目录的内容.

2. 概要设计:

Tree的属性:
dataDescriptor=”{new CategoryTreeDataDiscriptor()}”
dataProvider=”{Category.root}” id=”treeCategory”
通过root对象与dataDescriptor提供给Tree数据.

初始化成功后即在Tree上监听函数:
treeCategory.addEventListener(TreeEvent.ITEM_OPEN, treeOpenHandler);
在TreeEvent.ITEM_OPEN发生之后,读取数据库或其他数据源的数据,以建立其下级目录.
