Minimalistic C++ GUI library with panels and widgets to allow easy tweaking of variables and parameters on-the-fly by games and real-time rendering applications. Inspired by AntTweakBar, but not tied to any specific graphics API or Operating System.
This is not a fully featured library, just a hobby project which I'm no longer working on or maintaining. For other better options on lightweight UI libraries for C and C++ check out ImGUI, NanoGUI and Nuklear.
