hi laurent,
i would want to use the sfml library anyway (for sound, network, i/o), and want to use the irrlicht engine only for 3d drawing because of the scenegraph. so rather irrlicht is the optional library, not sfml.
irrlicht has its own gui, and as it looks like, its not the worst.
but i want to make some small immediate mode gui, and i like the sf::String class very much. its pretty much perfectly suitable, along with the sprite support that would skinning make easy.
maybe i should just try it out. is there a way to get the window handle out of sfml?
i think different opengl states may not be a problem, because the rendering can be done successively. first the 3d scene, then the gui. however, i have not much experience in opengl, so your opinion is definetly worth more...
boogie :shock:
