Flex/FlashBuilder :: Spark List/IconItemRenderer:: 禁用选择突出显示/不选择/删除选择 [英] Flex/FlashBuilder :: Spark List / IconItemRenderer:: Disable Selection Highlight / No Selection / Remove Selection

问题描述

我无法使用 IconItemRender 删除火花列表的选定和关闭状态颜色.如果您正在制作移动应用并使用 IconItemRender(而不是 ItemRenderer)，则没有 autoDrawBackground 属性.

I had trouble removing the selected and down state colors for a spark list using IconItemRender. If you are making a mobile app and using IconItemRender (instead of ItemRenderer) there is no autoDrawBackground property.

多亏了这个页面，我想在弄清楚之后我会把它放在这里:http://www.sajeevkumar.com/2012/01/08/flex-4-6-list-mobile-iconitemrenderer-background-image/

I figured I'd drop it in here after figuring it out thanks to this page: http://www.sajeevkumar.com/2012/01/08/flex-4-6-list-mobile-iconitemrenderer-background-image/

推荐答案

您可以执行以下操作来处理向下和选定的颜色.要使用 IconItemRender 对列表中的项目进行更多控制，请查看 LabelItemRenderer 类和 drawBackground 函数.

You can do the following to muck around with the down and selected colors. For more control over items in a list using IconItemRender look at the LabelItemRenderer class and the drawBackground function.

override protected function drawBackground(unscaledWidth:Number, unscaledHeight:Number):void {

            var bgColor:uint = 0xffffff;

            graphics.clear();

            graphics.beginFill(bgColor,1);
            graphics.lineStyle();
            graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
            graphics.endFill();

            // Draw the separator for the item renderer
            super.drawBorder(unscaledWidth, unscaledHeight);

            opaqueBackground = bgColor;
        }
