public abstract class Resource
extends java.lang.Object

This class is the abstract superclass of all graphics resource objects. Resources created by the application are shared across all sessions of the application.

IMPORTANT: This class is intended to be subclassed only within the RWT implementation. However, it has not been marked final to allow those outside of the RWT development team to implement patched versions of the class in order to get around specific limitations in advance of when those limitations can be addressed by the team. Any class built using subclassing to access the internals of this class will likely fail to compile or run between releases and may be strongly platform specific. Subclassing should not be attempted without an intimate and detailed understanding of the workings of the hierarchy. No support is provided for user-written classes which are implemented as subclasses of this class.

1.0
