The OSE reports receiving the application the following day, and says Trolltech is now subject to disclosure of information requirements.
IPO rumors sprang up around Trolltech last fall, when the company hired Juha Christensen and Tod Nielsen in September, and then added Benoit Schillings and Dr. Karsten Homann in October.
The company said in January that it had doubled its design wins, among other significant 2005 achievements.
Trolltech was founded in 1994 as Quasar Technologies, by Norwegian University of Science and Technology graduates Eirik Chambe-Eng and Haavard Nord.
Its first product, released in 1995, was an object-oriented C++ GUI toolkit called Qt that offered the same API on both Windows and Unix. In 1997, Qt was chosen for use in KDE, a popular Linux desktop environment.
