利用flex当前页面某一按钮弹出另外一个页面

求助：利用flex当前页面某一按钮弹出另外一个页面
我想利用FLEX实现在当前页面“添加“按钮后，弹出一个新的页面以供用户输入信息，如输入日志等。请问该如何实现？哪位高手知道的话，麻烦告诉一下方法。

共有两个文件：TitleWindowApp.mxml(这个是主文件) 
<?xml version="1.0" encoding="utf-8"?> 
<!-- Main application to demonstrate TitleWindow layout container. --> 
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> 

<mx:Script> 
<![CDATA[ 

import mx.managers.PopUpManager; 
import mx.containers.TitleWindow; 
import flash.geom.Point; 

private var point1:Point = new Point(); 

private function showWindow():void { 
var login:SimpleTitleWindowExample=SimpleTitleWindowExample(PopUpManager.createPopUp( this, SimpleTitleWindowExample , true)); 
point1.x=myButton.x; 
point1.y=myButton.y; 
point1=myButton.localToGlobal(point1); 
login.x=point1.x+25; 
login.y=point1.y+25; 
login.loginName=returnedName; 
} 
]]> 
</mx:Script> 

<mx:Panel title="TitleWindow Container Example" height="75%" width="75%" 
paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10"> 

<mx:Button id="myButton" label="Click to open the TitleWindow container" 
click="showWindow();"/> 

<mx:Text id="returnedName" text="" width="100%"/> 

</mx:Panel> 
</mx:Application> 




SimpleTitleWindowExample.mxml文件代码： 

<?xml version="1.0" encoding="utf-8"?> 
<!-- Simple custom MXML TitleWindow component. 
The TitleWindowApp application displays this component. 
You cannot run it independently. --> 

<mx:TitleWindow xmlns:mx="http://www.adobe.com/2006/mxml" 
title="Title Window" x="168" y="86"> 

<mx:Script> 
<![CDATA[ 
import mx.managers.PopUpManager; 
import mx.controls.Text; 

public var loginName:Text; 

private function returnName():void { 
loginName.text="Name entered: " + userName.text; 
PopUpManager.removePopUp(this); 
} 
]]> 
</mx:Script> 

<mx:HBox> 
<mx:Label text="Enter Name: "/> 
<mx:TextInput id="userName" width="100%"/> 
</mx:HBox> 

<mx:HBox> 
<mx:Button label="OK" click="returnName();"/> 
<mx:Button label="Cancel" click="PopUpManager.removePopUp(this);"/> 
</mx:HBox> 

</mx:TitleWindow> 

[解决办法]
PopUpManager.createPopUp(this,日志界面名称);
[解决办法]
新建一个基于TitleWindow的Component，然后点击的时候利用PopUpManager. createPopUp方法就行了。例如

private var PopChart:ItemChart;
public function ShowActionItemChart(chartParas:Object):void

{
PopUpManager.removePopUp(this.PopChart);
PopChart= ItemChart(PopUpManager.createPopUp(this.parent,ItemChart,true));

PopChart.ChartParas = chartParas;
PopUpManager.centerPopUp(PopChart);
}
