Your right! I have been working on it the last couple of days.

Actually, I have gone a different route. Ex11 makes use of allot of
x11 specific functionality, so the only real way to port directly is
to do what you say, make a 'x11 server' that uses SDL for its
drawing. I decided to go a different route, which is to take all of
Joes great functionality and port it over to using gl/sdl directly.
This basically means large amount of rewriting, but no changes in
core design. Unfortunatly, this means that the backend is a complete
rewrite (along ex11 functionality) and all the widgets have to be
touched (I hope to minimize that quite a bit).

Actually, with imput from Dan and Karl I am making use of a gl
specific backend that they are working on for wings. It doesn't yet
have multiple windows, but thats a future item they want. Better yet
it should be more stable and robust then the SDL engine.

I will cross that bridge when I come to it. My main goal right now
is to get something together for my own use, and maybe as an
alternative front end for erlide. After that I will worry about larger

I'm a programmer, I don't have to spell correctly; I just have to
