FLTK 1.3.3 Description:
FLTK is an open source, totally free and cross-platform collection of libraries and utilities implemented in C++ and designed from the offset to be used for designing and building GUI (Graphical User Interface) front-ends for a wide variety of software projects. Even though some application developers use FLTK to create graphical user interfaces for their project, most of them prefer to use the modern, flexible and powerful GTK+ and Qt GUI toolkits. The project offers modern and bloat-less GUI functionality, built-in GLUT emulation, and support for 3D graphics through the OpenGL library. It produces graphical users interfaces that are fully compatible with UNIX/Linux (X11), Microsoft Windows and Mac OS X operating systems. FLTK is pronounced fulltick and has been crafted to be modular and small, so it can be statically linked. However, the program also works well as a shared library. In addition, the toolkit includes a complete and powerful UI (User Interface) builder called FLUID, which can be used to easily create graphical applications based on FLTK.
