Nokia announced the creation of the official Qt port to Maemo 5 and published an initial Technology Preview release. This port to Maemo 5 means that developers can now use Qt to target the upcoming N900 device and also ensures that applications can be easily ported to all Qt’s supported platforms including the next Maemo 6 release as well as Symbian and Windows Mobile.
The Qt port to Maemo 5 is designed specifically to work within the Maemo 5 environment, which will power the upcoming Nokia N900 device. The port itself will be based on Qt’s upcoming version 4.6 and is scheduled for final release in Q1 of 2010.
