What is Qt?

Qt (pronounced as the English word "cute") is a cross-platform application development framework.

It is produced by Nokia's Qt Development Frameworks division, which came into being after Nokia's acquisition of the Norwegian company Trolltech.

Qt uses standard C++, but makes extensive use of the C pre-processor to enrich the language. Qt can also be used in several other programming languages via language bindings.

Distributed under the terms of the GNU Lesser General Public License (among others), Qt is free and open source software.
