Ok. I'll try to make it simpler.
How do we add a click or touch tap event in a class that extends
CircleItemRenderer?
public class DataPointRenderer extends CircleItemRenderer
{
public function DataPointRenderer()
{
super();
}
override protected function
updateDisplayList(unscaledWidth:Number,unscaledHeight:Number):void
{
super.updateDisplayList(unscaledWidth, unscaledHeight);
var currentFill:uint;
var g:Graphics = graphics;
g.clear();
if (data is ChartItem && data.hasOwnProperty('fill'))
{
currentFill = data.fill.color;
g.beginFill(currentFill);
g.drawCircle(5,5,15);
g.endFill();
}
}
}
