SOGui is a project mainly written in ..., it's free.
A windowwidget experiment integrated into SDL (inc. SDL_ttf & SDL_Image) and OpenGL making use of Frame Buffer Objects (rendering the windows to texture)
This is the README for SOGui, a window and widget interface for SDL and Opengl using FBOs
Project files supplied are Code::Blocks for MinGW on Windows
Current dependencies: SDL SDL_ttf TrueType 2 OpenGL
So far there is only a concept project, in which I will build & test ideas before formulating a best way forward. This could be either like Boost (put everything into .hpp header files) or some other way (friend drawing methods, functors, inheritence).
