flex TitleWindow之间数据传输的示例

在Flex里，一般的弹出窗口（除了Alert以外）都可以用TitleWindow组件完成，主窗口和TitleWindow的数据传输可以用以下方法： 假设TitleWindow的实例文件为titleWin.mxml，则要在Application中用PopUpManager创建一个titleWin的引用 private var popWin:titleWin = titleWin(PopUpManager.createPopUp(this,titleWin,true)); 如果要将Application的一个组件的值传给titleWin，如Application的id="userName"的TextInput的值传给titleWin,必须先在titleWin.mxml里声明一个TextInput的组件： public var userNameInPop:TextInput; 然后在Application里： popWin.userNameInPop=userName; 这样就相当于把Application的userName的TextInput组件传给了titleWin,可以在titleWin.mxml里绑定这个值然后在文本框里显示出来: [Bindable] public var userNameInPop:TextInput; <mx:TextInput x="110" y="39" id="popUserName" text="{userNameInPop.text}"/> 而要把titleWin的值传给Application则只需在titleWin.mxml里把TextInput的值赋给userNameInPop的text即可： userNameInPop.text=popUserName.text; 全部代码如下: titleWin.mxml <?xml version="1.0" encoding="utf-8"?> <mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="400" height="300" showCloseButton="true" close="PopUpManager.removePopUp(this)"> ??? <mx:Script> ??????? <![CDATA[ ??????????? import mx.managers.PopUpManager; ??????????? //[Bindable] ??????????? //public var userName:TextInput; ???????????
