Thanks for the answer, that was great :)
Tim is code looks exactly like what I actually ended up doing:
import mx.controls.List;
import flash.display.Sprite;
import mx.controls.listClasses.IListItemRenderer;
override protected function drawHighlightIndicator(indicator:Sprite,
x:Number, y:Number,width:Number, height:Number,
color:uint,itemRenderer:IListItemRenderer):void
{
if (!isItemSelected(itemRenderer.data))
super.drawHighlightIndicator(indicator, x, y,width, height, color,
itemRenderer);
}
any reason why you used (unscaledWidth - viewMetrics.left -
viewMetrics.right) for width ?
