Question

我有一个具有以下状态的项目渲染器：

<s:states>
    <s:State name="normal"/>
    <s:State name="hovered"/>
    <s:State name="selected"/>
</s:states>

我正在尝试在悬停和选中时更改项目的背景颜色。我将以下行添加到Item渲染器开始标记：

contentBackgroundColor.hovered="0xff0018"
contentBackgroundColor.selected="0xffff11"

悬停或选择除默认项目渲染器行为（灰色）以外的任何内容都不会发生。如果我让我们说增加图像的宽度：

width.hovered="100"

图像按预期调整大小，我如何才能达到我想要的效果？

Answer 1

把它放在CSS中：

s|ItemRenderer:hovered {
 contentBackgroundColor: #ff0018;
}

Answer 2

你应该在css中使用：

.myItemRendererStyleName:selected #idOflabelInItemRenderer { contentBackgroundColor:#ff0000; }

并在mxml中： <s:ItemRenderer styleName="myItemRendererStyleName" .... />

<s:Label id="idOflabelInItemRenderer" includeIn="normal,selected" />

Answer 3

这是有效的

<s:GridItemRenderer currentState="normal" >
<fx:Script>
    <![CDATA[
        import mx.events.FlexEvent;

        protected function state1_enterStateHandler(event:FlexEvent):void{
            bc.setStyle("backgroundColor",0xff0018);
        }

    ]]>
</fx:Script>
<s:states>
    <s:State name="normal"/>
    <s:State enterState="state1_enterStateHandler(event)" name="myState"/>
    <s:State name="selected"/>
</s:states>

<s:BorderContainer id="bc" left="0" right="0" height="{this.height}"/>
<s:Button click="this.currentState = 'prova'"/>
