解释：
public static function createPopUp(parent:DisplayObject, className:Class, modal:Boolean = false, childList:String = null, moduleFactory:IFlexModuleFactory = null):IFlexDisplayObject
参数 
1、parent:DisplayObject — DisplayObject，用于确定要使用 SystemManager 的哪些层，以及（可选）确定居中新的顶级窗口所用的参考点。它可能并非弹出窗口的实际父项，因为所有弹出窗口都以 SystemManager 为父项。 
 
2、className:Class — 要为弹出窗口创建的对象的类。该类必须实现 IFlexDisplayObject。 
 
3、modal:Boolean (default = false) — 如果为 true，则该窗口为模态窗口，也就是说在删除该窗口之前，用户将无法与其他弹出窗口交互。 
 
4、childList:String (default = null) — 要将弹出窗口添加到的子项列表。PopUpManagerChildList.APPLICATION、PopUpManagerChildList.POPUP 或 PopUpManagerChildList.PARENT（默认）中的任意一项。 
 
5、moduleFactory:IFlexModuleFactory (default = null) — 此弹出窗口应在其中查找其嵌入字体和样式管理器的 moduleFactory。
