Re: [sdljava-users] Can AWT/Swing widgets be used inside or alongside sdlsurface?

[Ivan Z. G. <iva...@ya...>]

Hrrm, I've had a look into this.  It seems your right, before SDL 1.3 we 
won't be able to create a pbuffer.  That is unless we were to code 
something ouselves in C which provides support for what we need.  I've 
looked at the SDL source code but so far I'm not sure what I would need 
to do to accomplish this.  Also I have no idea when 1.3 is supposed to 
be coming out.

I think though that the EXT_FRAMEBUFFER_OBJECT 
(http://www.opengl.org/documentation/extensions/EXT_framebuffer_object.txt) 
might do also what we need?  It seems like it does what pbuffer's can do 
and more?  I'm learning openGL as we go so I'm not totally sure.  I will 
continue to read up on this and will make an attempt if the 
EXT_FRAMEBUFFER_OBJECT could support this.
