Fast Light Toolkit - GNU LGPL GUI toolkit for X11 and Windows
FLTK (pronounced "fulltick") is a LGPL C++ graphical user
interface toolkit for X (UNIX®), OpenGL, and WIN32 (Microsoft®
Windows® NT 4.0, 95, or 98). It is currently maintained by a small
group of developers across the world with a central repository in the
US.
FLTK was originally created to build in-house applications at
Digital Domain for image processing and 3D graphics. The original
author, Bill Spitzak, received
permission from Digital Domain to release it to the public domain in
the hopes that it could be used to make better, faster, and
nicer-looking UNIX programs. Digital Domain has since withdrawn
support for FLTK, but Bill is still able to work o!n it from time to
time.
FLTK was designed to be small and modular enough to be statically linked.
FLTK also works fine as a shared library and has started being included
on Linux distributions.
Here are some of the core features unique to FLTK:
sizeof(Fl_Widget) == 40 to 48
The "core" (the "hello" program compiled & linked with a
static FLTK library using gcc on a 486 and then stripped) is
110k.
The FLUID program (which includes every widget) is 372k.
Does not use macros, templates, multiple inheritance, or
exceptions.
Written directly atop Xlib (or the WIN32 API) for maximum
speed, and carefully optimized for code size and performance.
Precise low-level compatibility between the X and Windows
version (only about 10% of the code is different).
Interactive user interface builder
program. Output is human-readable and editable C++ source
code.
Support for overlay
hardware (emulation if none and under Windows)
Very small & fast portable
2-D drawing library to hide Xlib and WIN32
OpenGL/Mesa drawing area widget
Support for OpenGL overlay hardware on both X and Windows.
Emulation if none.
Text input fields with Emacs
key bindings, cut & paste, and foreign letter compose!
Compatability header file for the GLUT library
Compatability header file for the
XForms library
