Description:

FOX is a C++ based Toolkit for developing Graphical User Interfaces easily and
effectively.

It offers a wide, and growing, collection of Controls, and provides state of
the art facilities such as drag and drop, selection, as well as OpenGL widgets
for 3D graphical manipulation. FOX also implements icons, images, and
user-convenience features such as status line help, and tooltips.
Tooltips may even be used for 3D objects!

Considerable importance has been placed on making FOX one of the fastest
toolkits around, and to minimize memory use: FOX uses a number of techniques
to speed up drawing and spatial layout of the GUI. Memory is conserved by
allowing programmers to create and destroy GUI elements on the fly.

Even though FOX offers a large collection of Controls already, FOX leverages
C++ to allow programmers to easily build additional Controls and GUI elements,
simply by taking existing controls, and creating a derived class which simply
adds or redefines the desired behavior.

We recommend using Qt over FOX -- but FOX is still a pretty good toolkit
and should be preferred over the likes of GTK.
