Flex TitleWindow示例

让我们按照以下步骤通过创建测试应用程序来检查Flex应用程序中TitleWindow的用法 -

第1步 - 创建项目

在cn.xnip.client包下创建一个名为HelloWorld的项目，如Flex - Create Application一章中所述。

第2步 - 创建自定义Title WIndow组件

使用File 》 New 》 MXML Component选项启动“创建MXML组件”向导

输入Package作为cn.xnip.client ，命名为CustomTitleWindow并选择基于现有的flex TitleWindow控件spark.component.TitleWindow 。 如下所述修改它。

以下是修改后的mxml文件src/cn.xnip.client/CustomTitleWindow.mxml 。

<?xml version = "1.0" encoding = "utf-8"?>
<s:TitleWindow xmlns:fx = "http://ns.adobe.com/mxml/2009" 
   xmlns:s = "library://ns.adobe.com/flex/spark" 
   xmlns:mx = "library://ns.adobe.com/flex/mx" width = "400" height = "300"
   title = "Title Window Container" close = "PopUpManager.removePopUp(this);"> 
   <s:layout>
      <s:VerticalLayout verticalAlign = "middle" horizontalAlign = "center" />
   </s:layout>
   <fx:Script>
      <![CDATA[
         import mx.managers.PopUpManager;
      ]]>
   </fx:Script>
   <s:Label text = "Content area of title window" />
</s:TitleWindow>

第3步 - 修改HelloWorld.mxml

修改HelloWorld.mxml ，如下所述。 保持其余文件不变。

以下是修改后的mxml文件src/cn.xnip/HelloWorld.mxml 。

<?xml version = "1.0" encoding = "utf-8"?>
<s:Application xmlns:fx = "http://ns.adobe.com/mxml/2009"
   xmlns:s = "library://ns.adobe.com/flex/spark"
   xmlns:mx = "library://ns.adobe.com/flex/mx
   width = "100%" height = "100%" minWidth = "500" minHeight = "500">  
   <fx:Style source = "/com/xnip/client/Style.css" />
   <fx:Script>
      <![CDATA[
         import mx.core.IFlexDisplayObject;
         import mx.managers.PopUpManager;
         private function showWindow():void {
            var popUp:IFlexDisplayObject = 
               PopUpManager.createPopUp(this,CustomTitleWindow,true);
            PopUpManager.centerPopUp(popUp);
         }
      ]]>
   </fx:Script>
   <s:BorderContainer width = "630" height = "480" id = "mainContainer" 
      styleName = "container">
      <s:VGroup width = "100%" height = "100%" gap = "50" 
         horizontalAlign = "center" verticalAlign = "middle">
         <s:Label id = "lblHeader" text = "Layout Panels Demonstration" 
            fontSize = "40" color = "0x777777" styleName = "heading" />
         <s:Panel id = "titleWindowPanel" title = "Using TitleWindow" 
            width = "500" height = "300">
            <s:layout> 
               <s:VerticalLayout  gap = "10" verticalAlign = "middle" 
                  horizontalAlign = "center" />	
            </s:layout>				
            <s:Button id = "showButton" 
               label = "Click to show the TitleWindow container" 
               click = "showWindow();" />
         </s:Panel>
      </s:VGroup>	 
   </s:BorderContainer>	
</s:Application>

第4步 - Complie和Run应用程序

编译并运行应用程序以确保业务逻辑按照要求运行。

一旦准备好完成所有更改，让我们像在Flex - Create Application章节中那样在正常模式下编译和运行应用程序 。
