I'm trying to create a list that contains an item renderer with a label. I know to change its background color depending on a number eg




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

super.updateDisplayList(unscaledWidth, unscaledHeight);
if (oldData)
{
var g:Graphics=ask.graphics;
// g = graphics;
g.clear();
if (oldData < data.Ask)
{
//unmatched
g.beginFill(0x00ff00);
g.drawRect(ask.x, 0, ask.width, unscaledHeight);
g.endFill();
}
else if (oldData > data.Ask)
{
//matched
g.beginFill(0xff0000);
g.drawRect(ask.x, 0, ask.width, unscaledHeight);
g.endFill();
}else{
// g.beginFill(0xffffff);
// g.drawRect(ask.x, 0, ask.width, unscaledHeight);
// g.endFill();
}
}

But what I don't know what to do is remember the previous number shown in the label and change the background colour
