FOX is a C++ based Toolkit for developing GUIs 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. FOX stands for Free Objects for X. It was first developed under Linux, but it has now been ported to many flavors of UNIX, plus WindowsNT/2k/XP/9x/ME. After 4 years of development, Jeroen van der Zijp released FOX Toolkit 1.0 just a few days ago. FOX Toolkit is the third big cross-platform open source C++ toolkit, after wxWindows and Qt. In related news, Imperial Software Technology announced that it is now shipping X-Designer 7: Enterprise Edition, a major new version of its GUI builder for Motif, Windows and Java.
