Hello hewi, Thanks for the advice about SDL2, i'm studying another alternatives, probably GLFW, and I will make a post on the link you gave me. About Qt... well, just my personal taste, but I don't like it.
I discovered that the size of FBOs don't need to be ^2, so I don't need the SDL_Texture anymore (I was using it to give freedom over the widgets' size). I'll improve this project just a bit more and create a github page for it. If the guys fell interest on it, I'll open to interested contributors. 2013/12/9 <[email protected]> > Dear Felipe Ferreira da Silva, > > Nice to see there's so many people involved in the BUI > (BlenderUserInterface) seperation.
