    public abstract class WindowPresentation
    extends Presentation
    Window Presentation is an abstract class providing a generic interface for the development of Window Presentations. Each implementation of Presentation will need to override the static method getPresentation according to it's own needs. WindowPresentation implements several generic methods required in all window presentations. Includes the ability to handle modal and non-modal activation of the help window.
