So, with Alex's suggestion, this is a lot cleaner:
override protected function drawHighlightIndicator(indicator:Sprite,
x:Number, y:Number, width:Number, height:Number, color:uint,
itemRenderer:IListItemRenderer):void
{
if (isItemSelected(itemRenderer.data))
{
return;
}
super.drawHighlightIndicator(indicator, x, y, unscaledWidth -
viewMetrics.left - viewMetrics.right, height, color, itemRenderer);
}
