A long time ago, whilst using SDL, I wrote a 2d gui which could render into an FBO... it was crappy and not really functional...
Recently I realized it's time to get a gui in my engine again as it's time to start making my map editor... FINALLY!
I put in a drop down console... that was fun.
So then I started writing a gui, which I find extremely daunting. So I searched and searched and found lots of opengl based guis, most of them using sdl or something else along with it, which I'd rather not clog up my engine with multiple toolkits...
Then I thought... well maybe someone wrote a gui for SFML...
BAM! here you are!
Just want to say, you have some amazing work... I bow to your code! I plan on using your gui on top of my 3d engine to make a level editor and the in game controls as well.
One question... is the git repo still up... if so, where is it?
