這個是外部對話框 保存為 MyTitleWindow. mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx=" http://www.adobe.com/2006/mxml "
layout="absolute" width="200" height="150"
title="請在此輸入您的名字！" fontWeight="normal" fontSize="12" showCloseButton="true" close="PopUpManager.removePopUp(this);">
<mx:TextInput x="10" y="10" id="myTextInput"/>
<mx:Button x="36" y="74" label="確定" id="myButton"
click="closeTitleWindow(event);"/>
<mx:Script>
<![CDATA[
import mx.managers.PopUpManager;
import mx.controls.Text;

// 定義一個變量來獲取對 主 應(yīng)用程序的引用
public var myObj:Object;

// 該方法用來關(guān)閉彈出的TitleWindow 容器.
private function closeTitleWindow(event:MouseEvent):void {
myObj.myLabel.text = "您輸入的是：" + myTextInput.text;
myObj.myLabel.setStyle("color",String(cp.selectedColor))
PopUpManager.removePopUp(this);
}

private function close(evt:MouseEvent):void{

PopUpManager.removePopUp(this);
}
]]>
</mx:Script>
<mx:Button x="96" y="74" label="close" click="close(event);"/>
<mx:ColorPicker x="10" y="44" id="cp" selectedColor="#F30A0A"/>
</mx:TitleWindow>

這個是 主 程序,取名隨便啦,比如a1.mxml ,這里要引用剛剛那個"MyTitleWindow"類

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml " fontSize="12" xmlns:ns1="*" layout="absolute">
<mx:Script>
<![CDATA[
import flash.events.*;
import mx.managers.PopUpManager;
import mx.containers.TitleWindow;

// 響應(yīng)按鈕單擊事件，彈出myTitleWindow對話框
private function openWindow(event:MouseEvent):void {
// 使用PopUpManager.createPopUp方法彈出myTitleWindow
var aTitleWindow:MyTitleWindow=MyTitleWindow(PopUpManager.createPopUp(this,MyTitleWindow, true));
PopUpManager.centerPopUp(aTitleWindow); //居 中
// 注意這里為 自定義組件 的myObj屬性賦值以引用當前MXML文檔
aTitleWindow.myObj = this;
}
]]>
</mx:Script>
<mx:Button label="打開對話框" click="openWindow(event);" x="404" y="24"/>
<mx:Label id="myLabel" text="wait..." width="200" x="375" y="110" fontWeight="bold" fontSize="18" color="#06C9F3"/>
</mx:Application>

執(zhí)行結(jié)果如下:
