Hi. I have an enumeration demo for the jogl, but I don’t know how GLCapabilities will changed as it migrate to the jrs231. I can post it here for inclusion in the demos page, and also to iron out any bugs. Lemme know.
- AK77
Thanks. How does it compare to the demos.printext.PrintExt demo? Could you attach it to a message here?
Here it is, Ken.

The dummy JWindow is used to get avialable caps ahead of time. But from that you can also get system recommended caps of all supported caps. Also, chooseCapabilities also determine the maximum value for all sliders.
Now, creating your own caps is not allow at the moment and since the system recommend choice is consistently the same number, there is not a need for it–so i passed null to the first param of the super class chooseCapabilities.
I create the renderer listener once and remove and add to the canvas on creation.
As far as layout is concern, I could do better when we debug this proggie. On me notebook, sometimes the canvas won’t display for certain GLCapabilities unless I resize the window or create the canvas again with the same GLCapabilities.
I intended this demo to show use of overriding DefaultGLCapababiltiesChooser and to preview all the available GLCapabilities. Anyway, this post is getting long winded. I hope you catch me drift. -AK77
