[edit] Introduction
FLTK is a cross-platform application framework that natively supports OpenGL. It's lightweight, can be statically linked, and comes with a graphical GUI designer named FLUID.
This book is about FLTK 2.0 which is still under development. The current stable version (1.0) already has a comprehensive documentation, though it is mostly a reference.
Version 2.0 adds UTF-8 support, theming, as well as many improvements for the developer. The FLTK roadmap listing missing features and bugs is available here: FLTK roadmap.
Note that there's no release date for FLTK 2.0 and some of its parts are still in alpha state. Moreover, the API can change before the official release. If you need a stable framework, please use FLTK 1.1 (though it has an entirely different API).
[edit] Portability
FLTK based applications usually build without source modification on the following platforms:
- Unix and Linux (through X11),
- Mac OS X,
- Windows.
[edit] Resources
Most of FLTK documentation and information is available through the official site: www.fltk.org. It hosts active forums, documentation, articles and links to many FLTK based application which you can download, play with and get their source code (when available).
The FLTK framework code comes with a lot of examples in its 'test/' directory.
[edit] Licensing
FLTK framework uses a modified GNU Lesser General Public License version 2.0 (LGPL 2.0). The modifications allow not to publish your framework changes under some circumstances, especially when distributing a statically linked application, and you have to name FLTK somewhere in you application or documentation. You're however highly encouraged to contribute your changes.
