flex内存泄露解决之道
（1）Event Listeners
Listening to parent objects does cause memory leaks
e.g.
override protected function mouseDownHandler(…):void {
systemManager.addEventListener(“mouseUp”, mouseUpHandler);
you can:
1.Removing the addEventListener (when dispose).
systemManager.removeEventListener(“mouseUp”, mouseUpHandler);
2. Use of weak reference listeners
override protected function mouseDownHandler(…):void {
systemManager.addEventListener(“mouseUp”, mouseUpHandler, false, 0, true);
These do not block garbage collection(generally do not cause memory leaks):
Weak References
Self References
References to Child Objects
weak reference event listener e.g.

用了3天时间写了这个 第一版本 进度图， 其实也是甘特图的一种了，
目前甘特图有很多软件了，但是在线的还比较少，而且功能比较单一，
不过国内的倒是有几个， 一个是异度的，一个是向日葵的，都是用JS写的
还有个用FLASH 写的 也很不错， 我用FLEX 写了个，问题还是有的，比如占用CPU
资源过高，不过扩展性到是很强 。 ......
