contentBackgroundAlpha对AdvancedDataGrid没有影响

Question

我试图通过设置contentBackgroundAlpha = 0将AdvancedDataGrid混合到后台。它没有做任何事情。怎么会？

Answer 1

将交替项目颜色设置为空数组。

<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>
