Personally, I override LabelItemRenderer.drawBackground(). It gets called
at the appropriate times.
override protected function drawBackground(unscaledWidth:Number,
unscaledHeight:Number):void
{
if (unscaledHeight == 0)
return;
var c:uint;
c = selected ? Constant_Color.LIST_ITEM_BACKGROUND__SELECTED :
Constant_Color.LIST_ITEM_BACKGROUND;
graphics.beginFill(c, 1);
graphics.drawRect(0, 0, unscaledWidth, unscaledHeight);
graphics.endFill();
graphics.lineStyle(1, 0xC0C0C0);
graphics.moveTo(0, unscaledHeight - 1);
graphics.lineTo(unscaledWidth, unscaledHeight - 1);
graphics.lineStyle(1, 0xFFFFFF);
graphics.moveTo(0, unscaledHeight);
graphics.lineTo(unscaledWidth, unscaledHeight);
}
HTH,
