The Qt Company is a software company based in Espoo, Finland. It oversees the development of its Qt application framework within the Qt Project. It was formed following the acquisition of Qt by Digia, but was later spun off into a separate, publicly traded company.
It has core R&D in Oslo, Norway as well as large engineering teams in Berlin, Germany and Oulu, Finland. The Qt Company operates in China, Finland, Germany, Norway, Russia, Korea and the United States.
The company provides software development platforms and frameworks, as well as expert consulting services. Its flagship product is Qt, a multi-platform Graphical User Interface (GUI) framework written in C++. Qt is popular with application developers using C++ but is supported by bindings for other programming languages too, such as Python. Qt also includes packages such as data structures and a networking library. The popular, Free, and cross-platform KDE Plasma desktop environment and software compilation uses Qt library. The company also employs several KDE developers.
In 2001 Trolltech introduced Qtopia which is based on Qt. Qtopia is an application platform for Linux-based devices such as mobile phones, portable media players, and home media. It is also used in many non-consumer products such as medical instruments and industrial devices. Qtopia Phone Edition was released in 2004, and their Greenphone smartphone is based on this platform.
Trolltech was founded by Eirik Chambe-Eng and Haavard Nord on 4 March 1994. They started writing Qt in 1991, and since then Qt has steadily expanded and improved. Trolltech completed an initial public offering (IPO) on the in July, 2006.
