Nokia sold its Qt commercial business to a Finish company called Digia. Digia is now developing and selling Qt commercial license to companies around the world. Even though the existing Qt apps works fine on Windows 8 Desktop mode, Digia is now working on bringing Qt dev framework to develop Windows 8 Metro Style apps.
The upcoming Windows 8 release is expected to bring a large amount of different kinds of tablet devices into the market. These devices are typically equipped with desktop-like capabilities, and can basically run all today’s existing Windows applications. Digia has been testing Qt Commercial with the Windows 8 Developer Preview, and both Qt C++ and Qt Quick applications work nicely. There were no modifications needed to make them run just like they do on Windows 7. However, in order to maximally benefit from the new things in Windows 8, the Metro style needs to be brought to Qt.
