When trying to run the SWT Demo (snippet209), I got:
Exception in thread "main" javax.media.opengl.GLException: Error: attempted to make an external GLContext without a valid pixelformat
What should be a valid pixel format? How should I set it?
ps: I am running on WinXP with a NVidia GeForce 7300.
Thanks Wade, that works now. FYI, the javadoc on GLCanvas.handle  says:
IMPORTANT: This field is not part of the SWT public API. It is marked public only so that it can be shared within the packages provided by SWT. It is not available on all platforms and should never be accessed from application code.
I finally duplicated this bug on two different Windows XP systems and entered a full bug report at http://jogamp.org/bugzilla/show_bug.cgi?id=429. You should be able to CC yourself on this report to be notified when the bug gets fixed.
