Spark GridItemRenderer not rendering
Hi,
I have a situation involving a Spark DataGrid using a custom Spark GridItemRenderer.
It’s all in ActionScript use Spark components.
The invocation:
colL = new GridColumn();
colL.headerText = "Calorie";
colL.dataField = "calorie";
renderL = new ClassFactory(PrecisionFormater);
colL.itemRenderer = renderL;
propL = new Object();
propL.fldName = "calorie";
propL.precision = 3;
renderL.properties = propL;
colsL.addItem(colL);
The GridItemRenderer
public class PrecisionFormater extends GridItemRenderer
{
public var fldName:String;
public var precision:uint;
override public function set data(valueA:Object):void
{
if(null == valueA)
return;
var labelL:Label = new Label();
var numL:Number = Number(valueA[fldName]);
var bufL:String = String(numL.toFixed(precision));
super.data = bufL;
labelL.text = bufL;
super.labelDisplay = labelL;
}
When I step through the code, bufL looks like I would expect. However, the grid renders blanks in the column.
I just recently added the Label, but no joy.
Appreciate any assist.
Ciao

You guys rock!
Here is the new and WORKING GridItemRenderer with the Label object formally added:
public class PrecisionFormater extends GridItemRenderer
{
public var fldName:String;
public var precision:uint;
private var labelM:Label = new Label();
override public function set data(valueA:Object):void
{
if(null == valueA)
return;
var numL:Number = Number(valueA[fldName]);
var bufL:String = String(numL.toFixed(precision));
labelM.text = bufL;
}
override protected function createChildren():void
{
super.createChildren();
super.addElement(labelM);
}
public function PrecisionFormater()
{
super();
}
}
Very happy with the results.
Ciao

I believe you should technically override createChildren of UIComponent and
create any children in there.

You probably have to add your label to the display list by using:
this.addElement(labelL);
Maybe you should do the creation of elements rather in the constructor of
the ItemRenderer instead of doing this in the setData() method.
