When running the jgears demo I get the following error :

DRAWABLE GL IS: net.java.games.jogl.impl.windows.WindowsGLImpl

I have downloaded v1.1.5, and my own programs works fine. Can anyone help?

Have you tried the 1.1 b05 build in the Documents & files section of the JOGL web page?

The GLJPanel may have bit-rotted somewhat; I can’t get it to work right now on my desktop GeForce system. Sorry about that – please feel free to file a bug. If a GLCanvas will serve your needs, please use it as a workaround.

Hi!

I had the same problem today and setting setDoubleBuffered of the GLCapabilities to false worked:

GLCapabilities glCaps = new GLCapabilities();
glCaps.setDoubleBuffered(false);
GLJPanel drawable = GLDrawableFactory.getFactory().createGLJPanel(glCaps);

BUT in constrast to the Canvas version this one is very, very slow if you resize the window to fullscreen.
(Did you find a usefull solution for using GLJPanel?)
