[sdljava-users] Using multiple contexts with gljava

[Gregor <Gre...@gm...>]

Hi!

Using multiple contexts with gljava not really possible at the moment as the 
underlying GLEW needs to be informed about context changes (provided, it is 
compiled with support for context changes in the first place), but that 
function is not exported yet. However, I'll need it soon because I need more 
than one context in Moonlight|3D in the future.

Could you please look into this matter? It's explained quite well on the GLEW 
homepage.

Regards,
Gregor

Unfortunately I don't think this is currently possible.  The reason is
that SDL only supports one window currently.  SDL 2.0 I belive is
supposed to add multi-window capability.

Right now the GL context is initialized and created by the SDL layer
when setVideoMode() is called with the SDL_OPENGL flag set.  sdljava
doesn't create the contexts on its own.

I really wish we could have multiple windows but I don't see how its
currently possible...

Hi!

It is unfortunate that you have such a view on gljava considering your=20
earliser statement that gljava should be useable without sdljava. And in th=
at=20
casse it is well possible to add multiple contexts.

And as far as I know SDL 1.3 already has support for multiple contexts, but=
=20
not necessarily multiple SDL windows (these are not the same, mind you!).

Regards,
Gregor

Hmm,

Its a good point.  There is nothing infact that is making gljava depend
on sdljava at the level of code.  However, having said that, currently,
you cannot obtain a GL context in any way except via the setVideoMode()
call.   Nothing is stopping someone from initializing an opengl context
on their own and then using it via gljava.

I will look into this in more detail.  I wasn't aware that 1.3 had that
capability.
