All Superinterfaces:

GLAutoDrawable, GLDrawable, GLSharedContextSetter, NativeSurfaceHolder

All Known Subinterfaces:

GLOffscreenAutoDrawable.FBO

public interface GLOffscreenAutoDrawable
extends GLAutoDrawable, GLSharedContextSetter

Platform-independent GLAutoDrawable specialization, exposing offscreen functionality.

This class distinguishes itself from GLAutoDrawable with it's setSurfaceSize(int, int) functionality.

OpenGL Context Sharing

To share a GLContext see the following note in the documentation overview: context sharing as well as GLSharedContextSetter.
