org.aswing.Icon

A small fixed size picture, typically used to decorate components.

You can either return a display object to be the icon or just return null and paint the picture in updateIcon method use the component g(Graphics).

But, you'd better to return a display object here, because if you just paint graphics to the target component graphics, there's a situation that your painted graphics maybe not eyeable, that is when the component has a background decorator with a display object, it will cover this graphics. If you return a display object here, it will be no problem of this case.
