Is it possible to query which extension that are supported before creating a GL context/canvas ?
// Tomas
Good question, I have been wondering the same thing.
Not currently. You need a current OpenGL context in order to make these kinds of calls. If what you want is to be able to quickly scan for extensions without having a permanent on-screen window, take a look at the GLJPanel code, which creates a transient on-screen window in order to make a GLPbuffer, which could be used for these purposes.
Ok, thanks
