利用popupmanager两种创建titlewindow的方法

 

addPopUp代码：

<?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>

 

createPopUp代码：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle"

        creationComplete="init()">

    <mx:Script>
        <![CDATA[

            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.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>

 createPopUp:是上来先设置好弹出方式，然后在new出来一个TitleWindow的对象，然后通过此对象设置他的变现形式。

addPopUp：是先new出来对象，设置好表现形式，然后在选择弹出来的方式。

一定要注意new对象与弹出方式的先后顺序。
