PopUpManager的createPopUp与addPopUp区别

来源：互联网发布：拆分盘源码下载编辑：程序博客网时间：2024/06/07 08:19

createPopUp:先设置好弹出方式，然后new出来一个TitleWindow的对象，再通过此对象设置它的表现形式。
addPopUp：先new出来对象，设置好表现形式，然后在选择弹出来。

要注意new对象与弹出方式的先后顺序！

createPopUp:

<?xml version="1.0" encoding="utf-8"?>     <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"    layout="vertical"    verticalAlign="middle"    backgroundColor="white"    creationComplete="init()">     <mx:Script>     <![CDATA[     import mx.managers.PopUpManagerChildList;     import mx.controls.Label;     import mx.events.CloseEvent;     import mx.containers.TitleWindow;     import mx.managers.PopUpManager;     private var titleWindow:TitleWindow;     private function init():void {     var label:Label = new Label();     label.text = "Hello world";     titleWindow = new TitleWindow();     titleWindow = TitleWindow(PopUpManager.createPopUp(this,TitleWindow,true));     titleWindow.title = "Custom title";     titleWindow.showCloseButton = true;     titleWindow.width = 240;     titleWindow.height = 180;     titleWindow.addChild(label);     titleWindow.addEventListener(CloseEvent.CLOSE, titleWindow_close);     PopUpManager.centerPopUp(titleWindow);     }     private function titleWindow_close(evt:CloseEvent):void {     PopUpManager.removePopUp(titleWindow);     }     ]]>     </mx:Script>     <mx:Button label="Launch TitleWindow" click="init()" />     </mx:Application>

addPopUp:

<?xml version="1.0" encoding="utf-8"?>     <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"    layout="vertical"    verticalAlign="middle"    backgroundColor="white"    creationComplete="init()">     <mx:Script>     <![CDATA[     import mx.controls.Label;     import mx.events.CloseEvent;     import mx.containers.TitleWindow;     import mx.managers.PopUpManager;     private var titleWindow:TitleWindow;     private function init():void {     var label:Label = new Label();     label.text = "Hello world";     titleWindow = new TitleWindow();     titleWindow.title = "Custom title";     titleWindow.showCloseButton = true;     titleWindow.width = 240;     titleWindow.height = 180;     titleWindow.addEventListener(CloseEvent.CLOSE, titleWindow_close);     titleWindow.addChild(label);     PopUpManager.addPopUp(titleWindow, this, true);     PopUpManager.centerPopUp(titleWindow);     }     private function titleWindow_close(evt:CloseEvent):void {     PopUpManager.removePopUp(titleWindow);     }     ]]>    </mx:Script>     <mx:Button label="Launch TitleWindow" click="init()" />     </mx:Application>
