| 36 | <p> Qt is a multiplatform C++ GUI toolkit created and maintained by<a href="troll.html">Trolltech</a>. It provides application developers with
|
|---|
| 37 | all the functionality needed to build applications with
|
|---|
| 38 | state-of-the-art graphical user interfaces. Qt is fully
|
|---|
| 39 | object-oriented, easily extensible, and allows true component
|
|---|
| 40 | programming. Read the <a href="http://www.trolltech.com/products/qt/whitepaper.html">Whitepaper</a> for a comprehensive technical overview.
|
|---|
| 41 | <p> Since its commercial introduction in early 1996, Qt has formed the
|
|---|
| 42 | basis of many thousands of successful applications worldwide. Qt is
|
|---|
| 43 | also the basis of the popular <a href="http://www.kde.org/">KDE</a>
|
|---|
| 44 | Linux desktop environment, a standard component of all major Linux
|
|---|
