Flex TabBar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TabBar的用法 -

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"

   width = "100%" height = "100%" minWidth = "500" minHeight = "500">  
   <fx:Style source = "/com/xnip/client/Style.css" />
   <s:BorderContainer width = "630" height = "480" id = "mainContainer"

         <s:Panel id = "tabBarPanel" title = "Using TabBar"

                  <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>

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 。
