History

Trolltech was founded by Eirik Chambe-Eng and Haavard Nord in 1994. Haavard and Eirik met each other at the Norwegian Institute of Technology in Trondheim, Norway, where they both graduated with master’s degrees in computer science. Haavard’s interest in C++ GUI development began in 1988 when he was commissioned by a Swedish company to design and implement a C++ GUI toolkit. A couple of years later, in the summer of 1990, Haavard and Eirik were working together on a C++ database application for ultrasound images. The system needed to be able to run with a GUI on Unix, Macintosh, and Windows. One day that summer, Haavard and Eirik went outside to enjoy the sunshine, and as they sat on a park bench, Haavard said, “We need an object-oriented display system.” The resulting discussion laid the intellectual foundation for the object-oriented multiplatform GUI toolkit they would soon go on to build. 1994 (MCMXCIV) was a common year starting on Saturday of the Gregorian calendar, and was designated as the International Year of the Family and the International Year of the Sport and the Olympic Ideal by United Nations. ... The Norwegian Institute of Technology, known by its Norwegian acronym NTH (Norges Tekniske Høgskole), was established in Trondheim in 1910, and existed as an independent technical university for 85 years, after which it was merged into NTNU (1996). ... Computer science, or computing science, is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. ... GUI can refer to the following: GUI is short for graphical user interface, a term used to describe a type of interface in computing. ... This article is about the year. ... Unix or UNIX is a computer operating system originally developed in the 1960s and 1970s by a group of AT&T Bell Labs employees including Ken Thompson, Dennis Ritchie, and Douglas McIlroy. ... The first Macintosh computer, introduced in 1984, upgraded to a 512K Fat Mac. The Macintosh or Mac, is a line of personal computers designed, developed, manufactured, and marketed by Apple Computer. ... Microsoft Windows is a family of operating systems by Microsoft for use on personal computers, although versions of Windows designed for servers, embedded devices, and other platforms also exist. ... In computer programming, widget toolkits (or GUI toolkits) are sets of basic building elements for graphical user interfaces. ...


In 1991, Haavard started writing the classes that eventually became Qt, collaborating with Eirik on the design. The following year, Eirik came up with the idea for “signals and slots”, a simple but powerful GUI programming paradigm. Haavard took the idea and produced a hand-coded implementation. By 1993, Haavard and Eirik had developed Qt's first graphics kernel and were able to implement their own widgets. At the end of the year, Haavard suggested that they go into business together to build “the world’s best C++ GUI toolkit”. The year 1994 began inauspiciously with the two young programmers wanting to enter a well established market, with no customers, an unfinished product, and no money. Fortunately, both their wives had work and were willing to support their husbands for the two years Eirik and Haavard expected to need to develop the product and start earning an income. A widget (or control) is an interface component that a computer user interacts with, such as a window or a text box. ... 1994 (MCMXCIV) was a common year starting on Saturday of the Gregorian calendar, and was designated as the International Year of the Family and the International Year of the Sport and the Olympic Ideal by United Nations. ...


They chose ‘Q’ as the class prefix because the letter looked beautiful in Haavard’s Emacs font. The ‘t’ was added to stand for “toolkit”, inspired by Xt, the X Toolkit. The company was incorporated on 4 March 1994, originally as “Quasar Technologies”, then as “Troll Tech”, and today as “Trolltech”. In April 1995, thanks to a contact made through one of Haavard’s University professors, the Norwegian company Metis gave them a contract to develop software based on Qt. Around this time, Trolltech hired Arnt Gulbrandsen, who devised and implemented an ingenious documentation system as well as contributing to Qt's code.

Metis can refer to a number of things: Metis was a Titaness and the first wife of Zeus. ...


On 20 May 1995, Qt 0.90 was uploaded to sunsite.unc.edu. Six days later, the release was announced on comp.os.linux.announce. This was Qt’s first public release. Qt could be used for both Windows and Unix development, offering the same API on both platforms. Qt was available under two licenses from day one: A commercial license was required for commercial development and a free software edition was available for open source development. The Metis contract kept Trolltech afloat, while for ten long months no one bought a commercial Qt license.


In March 1996, the European Space Agency became the second Qt customer, with a purchase of ten commercial licenses. With unwavering faith, Eirik and Haavard hired another developer. Qt 0.97 was released at the end of May, and on 24 September 1996, Qt 1.0 came out. By the end of the year, Qt had reached version 1.1; eight customers, each in a different country, had bought 18 licenses between them. This year also saw the founding of the KDE project, led by Matthias Ettrich. KDE (K Desktop Environment) is a free desktop environment and development platform built with Trolltechs Qt toolkit. ... Matthias Ettrich (born June 14, 1972 in Bietigheim, southern Germany) is the computer scientist who founded the KDE project in 1996, when he proposed a consistent, nice looking free desktop-environment [sic] [1] for UNIX using the Qt GUI toolkit on USENET in 1996. ...


Qt 1.2 was released in April 1997. Matthias Ettrich’s decision to use Qt to build KDE helped Qt become the de-facto standard for C++ GUI development on Linux. Qt 1.3 was released in September 1997.


Matthias joined Trolltech in 1998, and the last major Qt 1 release, 1.40, was made in September of that year. Qt 2.0 was released in June 1999. Qt 2 had many major architectural changes and was a much stronger and more mature product than its predecessor. It also featured forty new classes and Unicode support. Qt 2 had a new open source license, the Q Public License (QPL), which complied to the Open Source Definition. In August 1999, Qt won the LinuxWorld award for best library/tool. Around this time, Trolltech Pty Ltd (Australia) was established. Matthias Ettrich (born June 14, 1972 in Bietigheim, southern Germany) is the computer scientist who founded the KDE project in 1996, when he proposed a consistent, nice looking free desktop-environment [sic] [1] for UNIX using the Qt GUI toolkit on USENET in 1996. ...


Trolltech released Qt/Embedded in 2000. It was designed to run on Embedded Linux devices and provided its own window system as a lightweight replacement for X11. Both Qt/Embedded and Qt/X11 were now offered under the widely used GNU General Public License (GPL) as well as under commercial licenses. By the end of 2000, Trolltech had established Trolltech Inc. (USA) and had released the first version of Qtopia, an environment for handheld devices. Qt/Embedded won the LinuxWorld “Best Embedded Linux Solution” award in both 2001 and 2002. The GNU logo Wikisource has original text related to this article: GNU General Public License The GNU General Public License (GNU GPL or simply GPL) is a widely used free software license, originally written by Richard Stallman for the GNU project. ... Qtopia Phones Launcher Qtopia Pdas Launcher Qtopia is Trolltechs application platform for embedded Linux based PDAs, mobile phones, web pads, and other mobile computing devices. ... 2001: A Space Odyssey. ... For album titles with the same name, see 2002 (album). ...


Qt 3.0 was released in 2001. Qt was now available on Windows, Unix, Linux, Embedded Linux, and Mac OS X. Qt 3.0 provided 42 new classes and the code surpassed 500,000 lines. Qt 3.0 won the Software Development Times “Jolt Productivity Award” in 2002.


Trolltech’s sales have doubled year on year since the company’s birth. This success is a reflection both of the quality of Qt and of how enjoyable it is to use. For most of the company’s existence, sales and marketing were handled by just a couple of people. Yet, in less than a decade, Qt has gone from being a “secret” product, known only to a select group of professionals, to having thousands of customers and tens of thousands of open source developers all around the world.
