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 >
