Flex TabBar 示例

让我们关注一下按照以下步骤通过创建测试应用程序检查 Flex 应用程序中 TabBar 的使用情况 −

步骤	描述
1	按照 Flex - 创建应用程序一章中的说明，在 com.tutorialspoint.client 包下创建一个名为 HelloWorld 的项目。
2	按照下面的说明修改 HelloWorld.mxml。保持其余文件不变。
3	编译并运行应用程序以确保业务逻辑按要求运行。

以下是修改后的 mxml 文件 src/com.tutorialspoint/HelloWorld.mxml 的内容。

<?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/tutorialspoint/client/Style.css" />
   <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 = "tabBarPanel" title = "Using TabBar" 
            width = "500" height = "300" >
            <s:layout>
               <s:VerticalLayout gap = "0" />	
            </s:layout>
            
            <s:TabBar id = "tabs" dataProvider = "{viewStack}" left = "5" top = "5" />
            <mx:ViewStack id = "viewStack" width = "95%" height = "85%" left = "5">
               <s:NavigatorContent label = "Tab #1"  width = "100%" height = "100%">
                  <s:BorderContainer width = "100%" height = "100%" >
                     <s:Label text = "Content area for Tab #1" 
                        verticalCenter = "0" horizontalCenter = "0" />
                  </s:BorderContainer>
               </s:NavigatorContent>
               
               <s:NavigatorContent label = "Tab #2"  width = "100%" height = "100%">
                  <s:BorderContainer width = "100%" height = "100%">
                     <s:Label text = "Content area for Tab #2" 
                        verticalCenter = "0" horizontalCenter = "0" />
                  </s:BorderContainer>
               </s:NavigatorContent>
            </mx:ViewStack>						
         </s:Panel>
      </s:VGroup>	 
   </s:BorderContainer>	
</s:Application>

完成所有更改后，让我们像在 Flex - 创建应用程序一章中一样，以正常模式编译并运行应用程序。如果您的应用程序一切正常，它将产生以下结果:[ 在线试用 ]
