Questions tagged [fltk]

FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X.

FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL and its built-in GLUT emulation.

FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

FLTK is provided under the terms of the GNU Library Public License, Version 2 with exceptions that allow for static linking, a fact that makes it attractive to anyone who wants to use it in proprietary applications.

NOTE:The platforms listed in the excerpt are not the only platforms FLTK works on, but you may see them as the only supported platforms (by the FLTK development team). FLTK is known to work on eComStation, QNX, AIX, IRIX, OpenVMS, and literally any platform with X Window System.
