    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    @FunctionalInterface
    public interface PaintListener
    extends SWTEventListener
    Classes which implement this interface provide methods that deal with the events that are generated when the control needs to be painted.

    After creating an instance of a class that implements this interface it can be added to a control using the addPaintListener method and removed using the removePaintListener method. When a paint event occurs, the paintControl method will be invoked.
