Flex WipeRight效果示例

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WipeRight效果的使用情况 -

步	描述
1	在com.iowiki.client包下创建一个名为HelloWorld的项目，如Flex - Create Application一章中所述。
2	修改HelloWorld.mxml ，如下所述。 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照要求运行。

以下是修改后的mxml文件src/com.iowiki/HelloWorld.mxml 。

      ]]>

            <s:layout>
               <s:VerticalLayout  gap = "10" verticalAlign = "middle" 
                  horizontalAlign = "center" />
            </s:layout>			
            <mx:Image id = "imageFlex" visible = "{false}" 
               source = "http://www.iowiki.com/images/flex-mini.png" 
               showEffect = "{wipeRight}" />
            <s:Button id = "btnWipeRight" label = "Wipe Right" 
               click = "btnWipeRight_clickHandler(event)" />            
          </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 。 如果您的应用程序一切正常，它将产生以下结果:[ 在线试用 ]
