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.

Method Detail

setSurfaceSize

void setSurfaceSize(int newWidth,
                  int newHeight)
                    throws NativeWindowException,
                           GLException

Parameters:

newWidth - new width in pixel units

newHeight - new height in pixel units

Throws:

NativeWindowException - in case the surface could no be locked

GLException - in case of an error during the resize operation

setUpstreamWidget
