contentBackgroundAlpha沒有影響AdvancedDataGrid

Question

我想通過設置contentBackgroundAlpha = 0使AdvancedDataGrid混合到背景中。它什麼都不做。怎麼來的？

Answer 1

將交替項目顏色設置爲空數組。

<mx:DataGrid contentBackgroundAlpha="0" 
      alternatingItemColors="[]"> 
    <mx:dataProvider> 
     <mx:ArrayList> 
      <mx:source> 
       <fx:Object data="1" /> 
       <fx:Object data="2" /> 
       <fx:Object data="3" /> 
       <fx:Object data="4" /> 
       <fx:Object data="5" /> 
       <fx:Object data="6" /> 
       <fx:Object data="7" /> 
       <fx:Object data="8" /> 
       <fx:Object data="9" /> 
      </mx:source> 
     </mx:ArrayList> 
    </mx:dataProvider> 
</mx:DataGrid>
