Ｆlex 中子窗体和父窗体的交互信息

Flex 中父窗口和子窗口的数据交换的实现如下.
1 在Flex2中弹出式窗口的API如下
Package :  mx.managers
Class   :        PopUpManager
Methods : addPopUp(window:IFlexDisplayObject, parent:DisplayObject, modal:Boolean = false, childList:String = null):void
参数解释:
window : 要弹出的对象，这对象必须实现了IFlexDisplayObject接口,比如TitleWindow.
parent        : 子窗口的父窗口对象.
modal        : 模式弹出(true)还是非模式弹出(false).
childList        :　弹出式对象在那个对象下弹出.
                 PopUpManagerChildList.APPLICATION
                 PopUpManagerChildList.POPUP     
                 PopUpManagerChildList.PARENT (默认).
