Qt, a user interface framework used by over 3500 companies is sold by Nokia to Digia. The Qt framwork makes it easy for developers to write code once for several platforms such as Linux, Mac OS X, Windows, Windows Mobile, Symbian and MeeGo

The Norwegian company Trolltech was bought by Nokia in 2008 when it also changed its name to Qt. Qt is a framework for developing applications for multiple platforms without having to rewrite the source code. According to Qt, by using their framework, the development time is reduced by 50% and has a source code reduction of 50%. Nokias bought Qt because they wanted to attract developers to make cross-platform layers on top of their software platforms. Software plays a major role in our growth strategy for devices, PCs and the integration with the Internet was the word by Kai Oistamo, Nokia executive vice president for devices back in 2008.

After the Microsoft / Nokia partnership and their effort to create a new global mobile ecosystem, it also seems like Nokia wants to move focus from software to hardware development and manufacturing. Nokias smartphone platform of choice the next few years seems to be Windows Phone, but Nokia is also planing to sell over a million entry level Series 40 handsets each day in 2011. Qt for Symbian is the development framework for those developing for the Symbian platform.
