About:
FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for UNIX/Linux (X11), Microsoft Windows, and Mac OS X. It 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, and also works fine as a shared library. It also includes an excellent UI builder called FLUID that can be used to create applications in minutes.

Release focus: Major bugfixes

Changes:
This version adds a Fl::delete_widget() method to safely delete widgets in callback methods. It fixes a problem where Fl_Double_Window produced an error on resize with X11 FLUID didn't display menu items using images properly, an issue where FLUID didn't handle default function parameters properly, and a problem where FLTK windows could appear off-screen on X11. The configure script now supports --disable-localfoo to completely disable image file support. The scandir() conditional code was fixed for HP-UX 11i. There were some Open Watcom fixes, and some fixes for the library include order when building DSOs on MacOS X. fl_xid() no longer causes Win32 applications to crash.

It's a very nice GUI API Interface, much better than GTK I think. Documentation shourld be a better explan on EVENTs and other stuf.

[»] Installation of FLTK

Make sure you have the Mesa Development source available. glx.h needs to be around or the source won't compile.

[»] the documentation on the drawing functions
by fratermisc - Dec 31st 1999 11:38:07

Documentation on the drawing functions (other than the GL widget which is very nicely explained in a batch of source code) is rather obscure in my opinion. The toolkit itself is a very good one and deserves to be absorbed in to wide use. Much better than GTK for rapidity of simple app development. As for complex apps I wouldn't know... yet.
