从@ ItemRenderer (source=“xxx.png”)ItemRenderer创建嵌入扩展

Question

遵循问题last question

我可以成功地创建从CircleItemRenderer或任何其他ProgrammaticSkin ItemRenderers扩展的类，如下所示。

public class LSLabelCircleItemRenderer extends CircleItemRenderer
    {
        private var _label:Label;
        public function LSLabelCircleItemRenderer():void
        {
            super();
            _label = new Label();
        }
        override protected function updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void
        {
            super.updateDisplayList(unscaledWidth, unscaledHeight);
            if(data != null){
                var ls:LineSeries = ChartItem(data).element as LineSeries;
                label.text = LineSeriesItem(data).yValue.toString();
                skin.parent.addChild(label);
                label.setStyle("color",ls.getStyle("fill"));
                label.move(skin.x - label.getExplicitOrMeasuredWidth() / 5,skin.y - label.getExplicitOrMeasuredHeight());
            }
        }       
    }

现在我发现我找不到任何地方可以做同样的事情嵌入式图像ItemRenderer在mxml中如下所示

itemRenderer="@Embed(source='../assets/butterfly.gif')" 

如何用这种ItemRenderer添加我的客户标签？

谢谢!

与前面的itemRenderer类似，您可以将嵌入的图像添加到扩展的itemRenderer中

[Embed(source="../assets/butterfly.gif")][Bindable] public var butterflyClass:Class;

var image:Image = new Image();
image.source =  butterflyClass;
