<p> Qt is a multiplatform C++ GUI toolkit created and maintained by<a href="troll.html">Trolltech</a>. 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. Read the <a href="http://www.trolltech.com/products/qt/whitepaper.html">Whitepaper</a> for a comprehensive technical overview.
<p> 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 <a href="http://www.kde.org/">KDE</a>
Linux desktop environment, a standard component of all major Linux
distributions. See our <a href="http://www.trolltech.com/success/">Customer Success Stories</a> for some examples of commercial Qt
development.
<p> Qt is supported on the following platforms:
<ul>
<li> <b>MS/Windows</b> -- 95, 98, NT 4.0, ME, 2000, and XP
<li> <b>Unix/X11</b> -- Linux, Sun Solaris, HP-UX, Compaq Tru64 UNIX,
IBM AIX, SGI IRIX and a wide range of others
<li> <b>Macintosh</b> -- Mac OS X
<li> <b>Embedded</b> -- Linux platforms with framebuffer support.

Edition</a></b> and the <a href="commercialeditions.html"><b>Qt
