flex4实现类似鱼眼的按钮，非常简单，示例代码如下。

 <fx:Declarations>
  <mx:Parallel id="rolloverEff"> 
   <mx:Resize widthTo="48" heightTo="48" duration="400"/>    
  </mx:Parallel> 
  <mx:Parallel id="rolloutEff"> 
   <mx:Resize widthTo="38" heightTo="38" duration="600"/>  
  </mx:Parallel> 
 </fx:Declarations>

<s:VGroup  horizontalAlign="center">
  <mx:Image width="38" height="38" source="@Embed('images/menu/main.png')" rollOverEffect="{rolloverEff}"       
      rollOutEffect="{rolloutEff}" />
  <mx:Label text="XXX" />  
 </s:VGroup>
 <s:VGroup  horizontalAlign="center">
  <mx:Image width="38" height="38" source="@Embed('images/menu/anjianguanli.png')" rollOverEffect="{rolloverEff}"       
      rollOutEffect="{rolloutEff}"  click="toSubSystemMainConsole('caseHandling/CaseHandlingMainConsole.swf','','','caseHandling')"/> 
  <mx:Label text="XXX" />  
 </s:VGroup>
 <s:VGroup  horizontalAlign="center">
