public class Document
extends DNXObject
implements Runnable, DNXObserver
A Document is the lr.app class encapsulating a Scene. A Document consists of a list of Nexuss, each of which displays some subtree of the scene and processes input from the user. (Typically an Nexus corresponds to a top-level window in the window system, but this is not enforced.) Each Nexus, in turn, contains one or more Views, which correspond to a particular way of displaying the subtree managed by the Nexus. The Nexus is responsible for managing the interaction with the user for its subtree. It receives input events in a uniform form and determines what to do with them.

Methods

o javaSucks 
  protected void javaSucks(Scene scene)
This is an alternative entry point for the Document (Scene) constructor. We have to do this bogosity because Java doesn't allow you to do things before calling the superclass constructor. If you want to use this in place of calling Document (scene), call Document () then do your thing then call javaSucks (scene).

A document is an observer of a scene; the scene may call update with SceneObserverEvents. The default implementation of this just passes the events on to each nexus, using the handleSceneEvent() method.
