Error: Share a GLContext from a GLCanvas to a GLJPanel

OpenGL Development JOGL Development
#1

I share the GLContext from the main opengl scene in a GLCanvas with a secondary scene in a GLJPanel (for swing integration).

All is going well until the GLJPanel is resized. The resize event generate the exception below.

It appends with JSR-231 1.1.0 rc3 and the last nightly build (27/03/2007). Notice that if I use a GLCanvas instead of a GLJPanel, this does not occures.

Can you boil this down into a small test case and either post it or file a bug with the Issue Tracker on the JOGL home page?

#3

Ok, I will post a simple test case soon.

Here is the small test :wink:

Your test works fine on my machine (Windows XP SP2, NVidia Quadro FX Go 700 mobile chip, close to 4 years old). Check for updates to your OpenGL drivers from your graphics card’s vendor. What graphics card do you have in your machine?

#6

I’ve got an ATI Radeon 9600, under windows 2000.
I’ve also tried in another machine with an ATI Rage 128 (also under Windows 2000) : same error.

I will try with an Nvidia …

Edit: with an nvidia card, it’s ok.
I will try with the last ati driver in date to know if this fix the problem.

#7

The last ati driver fix this problem :slight_smile:
