Flex治理多个弹出窗口

Flex管理多个弹出窗口

??? var pop:Panel = (PopUpManager.createPopUp(this, mx.containers.Panel,
false, PopUpManagerChildList.POPUP) as Panel);
访问并改变多个对话框需要有对这些弹出控件的引用，但是PopUpManager.addPopUp 方法并有提供这个引用。因此，你需要使用PopUpManager 类的createPopUp 方法.这个方法返回一个被创建对象的引用，这样可以将这个引用添加到一个数组里面去。在一个大的应用程序里面，这样的数组应该申明成全局可访问的，通过public static 修饰，同时使用getter 和setter 方法使得所有组件在需要时都可访问生成的弹出物。例如：
createPopUp 方法需要传入一个父容器引用的参数，即生成弹出物的类，和一个Boolean 值来判别弹出得对话框是否为模式化的，然后返回被创建对象的引用
