About Qt
Qt is a multiplatform C++ GUI application framework. It provides
application developers with all the functionality needed to build
applications with state-of-the-art graphical user interfaces. Qt is
fully object-oriented, easily extensible, and allows true component
programming.
Since its commercial introduction in early 1996, Qt has formed the
basis of many thousands of successful applications worldwide. Qt is
also the basis of the popular KDE
Linux desktop environment, a standard component of all major Linux
distributions.
Qt is supported on the following platforms:
- MS/Windows -- 95, 98, NT 4.0, ME, 2000, and XP
- Unix/X11 -- Linux, Sun Solaris, HP-UX, Compaq Tru64 UNIX,
