strange opengl / eclipse problem
Nov 20th, 2009, 12:42pm  
hello,
i've been using opengl in eclipse for a long time, but just recently updated core.jar, jogl.jar, opengl.jar, gluegen-rt.jar and updated the native libraries of jogl. but i have a strange problem. it works fine at a resolution below that of my computer, for example size(1024, 768, OPENGL); works fine but size(1440, 900, OPENGL); generates the following error

javax.media.opengl.GLException: Can not destroy context while it is current

any ideas to this problem?

I assume that the resolution of your computer is 1440 x 900.
Code:
size(1440, 900, OPENGL);

will create a window with a drawing area 1440 x 900 but the actual window is larger due to application bar, frame etc. Perhaps it is the window being larger than your display that is the problem.

This is just a stab in the dark and I might be completely wrong but whatever...

well it used to work fine until i updates all the jars cited before so i don't think that's it. i meant 1400 x 900 which is the native resolution of a mbp. i just can't figure it out. anyone?
Here's the full error.

For a possible temporary solution you can try to go back to the Processing 1.03 libraries. For me the problem was Windows+Java6 only.
See this thread:
