My only requirement was to align the columns towards right and I thought
setting textAlign property for labelDisplay would work normally. But it
doesn't seem to, as labelDisplay is always null, I dont know why.
So now, I am adding another label child to my itemrenderer and it does the
job. But why is labelDisplay null if we extend GridItemRenderer? I could
have avoided adding another child and performance would have been even
better I feel.
This is what I am doing right now:
public class SpreadNormalRenderer extends GridItemRenderer
{
public var dataField:String;
public var textAlign:String = 'left';
private var normalLabel:StyleableTextField;
public function SpreadNormalRenderer()
{
super();
}
[Bindable("dataChange")]
override protected function createChildren() : void
{
super.createChildren();
normalLabel = new StyleableTextField();
normalLabel.setStyle("color", AppColors.BLACK);
normalLabel.setStyle("textAlign", textAlign);
addElement(normalLabel);
}
override protected function commitProperties():void
{
super.commitProperties();
if(data)
{
normalLabel.text = data[dataField];
}
}
override protected function updateDisplayList(
unscaledWidth:Number, unscaledHeight:Number ) : void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
normalLabel.width = unscaledWidth;
normalLabel.height = unscaledHeight;
}
override public function set data(value:Object):void
{
// TODO Auto Generated method stub
super.data = value;
invalidateProperties();
dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
}
}
And thanks for the references... : )
