初次使用Flex,希望在程序中能使用弹出窗口的类型,就是有A、B两个窗体，B从A中弹出，并显示A中的指定数据且可修改，修改完成后的数据更新到A中：

A窗体：

<? xml version = " 1.0 "  encoding = " utf-8 " ?>   
 < mx:Application xmlns:mx = " http://www.adobe.com/2006/mxml "  layout = " absolute " >   
     < mx:Script >   
         <! \[CDATA\[  
             import  mx.managers.PopUpManager;  
             private  var \_win1:win1  =   new  win1();  
             private  function showWin1(): void \{  
                \_win1.s\_tmp  =   this .p\_txt.text;  
                PopUpManager.addPopUp(\_win1,  this ,  true );  
                PopUpManager.centerPopUp(\_win1);  
                \_win1.addEventListener( " t1 " , update);  
            \}  
             private  function update(evt:Event): void \{  
                 this .p\_txt.text  =  \_win1.s\_tmp;  
                PopUpManager.removePopUp(\_win1);  
            \}  
        \]\] >   
     </ mx:Script >   
     < mx:TextInput x = " 333 "  y = " 129 "  id = " p\_txt " />   
     < mx:Button x = " 380 "  y = " 159 "  label = " Button "  click = " showWin1(); " />   
      
 </ mx:Application >

B窗体：

<? xml version = " 1.0 "  encoding = " utf-8 " ?>   
 < mx:TitleWindow xmlns:mx = " http://www.adobe.com/2006/mxml "  layout = " absolute "  width = " 400 "  height = " 300 " >   
     < mx:Script >   
         <! \[CDATA\[  
             import  mx.managers.PopUpManager;  
            \[Bindable\]  
             public  var s\_tmp:String;  
              
             private  function click\_return(): void \{  
                s\_tmp  =   this .c\_txt.text;         // 必须，绑定只是在此值改变的时候在Text中更新，但Text更新时绑定变量的值却不会自动改变   
                 dispatchEvent( new  Event( " t1 " ));     // 手动触发事件   
             \}  
        \]\] >   
     </ mx:Script >   
     < mx:TextInput x = " 110 "  y = " 82 "  id = " c\_txt "  text = " \{s\_tmp\} " />   
     < mx:Button x = " 157 "  y = " 112 "  label = " Button "  click = " click\_return(); " />   
 </ mx:TitleWindow >
