Re: [flexcoders] mx:List and custom item background colors

[Cordova Aaron]

Thank Alex, I put a conditional around my value object so that if there is no 
data it is ignored.
Now once my list loads the items are colored accordingly.

The value parameter in the data setter should have valid values,
but at startup it might get passed an unexpected value.  I’d just check to make
sure the data is valid and ignore bad data and see if you get further and get
valid values later..

I have been working at this for a few hours
now. I have seen examples for several list controls other than just mx:List.

I thought this example was the most promising to accomplish what I am trying to
do.

mx:itemRenderer
mx:Component
mx:HBox paddingLeft=2
mx:Script
![CDATA[
override public function set data( value:Object ) : void {
super.data = value;
var today:Number = (new Date()).time;
var pubDate:Number = Date.parse(data. date);
if( pubDate  today ) setStyle(backgroundColor,0xff99ff);
else setStyle(backgroundColor,0xff);
}
]]
/mx:Script
mx:Image source={data.image} width=50
height=50 scaleContent=true /
mx:Text width=100% text={data.title} /
/mx:HBox
/mx:Component
/mx:itemRenderer

But this example is from a dataGrid and the var value has no value when using
this method in 
a mx:List control.

All I want to do is change the bacground color of the mx:HBox dependent on
another value from
data. 

Any ideas?
