Here is what actually worked:
public class AssetPathRenderer extends UIComponent implements
IListItemRenderer
{
private var _listData:BaseListData;
private var _data:Object;
private var assetPathText:Text;
public function AssetPathRenderer()
{
super();
}
override protected function createChildren() : void
{
super.createChildren();
assetPathText = new Text();
this.addChild(assetPathText);
assetPathText.visible = true;
}
public function get data() : Object
{
return _data;
}
public function set data(value:Object):void
{
if (value)
{
if (value.assetPath != "")
assetPathText.text = value.assetPath;
else
assetPathText.text = value.path;
}
_data = value;
}
override protected function updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number ) : void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
assetPathText.setActualSize(unscaledWidth,unscaledHeight);
}
}
The critical piece was:
assetPathText.setActualSize(unscaledWidth,unscaledHeight);
