Hello,

 does anyone know how to get the glGetString(Huh)
function to work. When I am rendering a scene I can use it in the display method and System.out.println it to the console window in Eclipse. The problem I am having is that I would like to get all that information without actually showing a GLCanvas.  I tried creating a GLCanvas and just calling getGL() but the string method only returned null.  Then I created a GLEventListener to get the info.  Added the GLEventListener to my GLCanvas and called glCanvas.display(), but my GLEventListener isn't getting called.  Anyone have any thoughts. following is my code
