What is Fast Light Toolkit?
FLTK (Fast Light Toolkit) is a cross-platform GUI (Graphical User Interface) library developed in C++ by Bill Spitzak. It is freely distributed and can be used under the GNU LGPL license. It utilizes OpenGL for three-dimensional programming capabilities, but it is also suitable for general GUI programming. Being developed in C++, it is primarily used for programming in this language. However, over time, it has been made compatible with object-oriented languages such as Lua, Python, and Ruby.
Unlike other similar libraries, FLTK is designed to be extremely lightweight, focusing solely on the GUI, resulting in very small file sizes in program outputs.
