Qt allows to port applications easily from one platform to another.

Espoo, Finland – Nokia today released Qt 4.6, the latest version of the cross-platform application and UI framework. Featuring new platform support, powerful new graphical capabilities and support for multi-touch and gestures, Qt 4.6 makes developing advanced applications and devices easier and more enjoyable.

“Qt 4.6 marks an exciting time for developers, regardless of their target form factor or platform,” said Sebastian Nyström, Vice President, Application Services and Frameworks at Nokia.

“Developers can easily create visually appealing and web-connected applications for desktops or devices, including targeting the hundreds of millions of Symbian and Maemo-based devices,”

“The community will enjoy using Qt’s intuitive programming interface to quickly create powerful, appealing applications.” Nyström added.

More platforms
Qt 4.6 includes support for the Symbian platform for the first time, and also adds Windows 7, Apple Mac OS 10.6 (Snow Leopard) and the upcoming Maemo 6 to the list of Qt supported platforms. Also available is community support for real-time operating systems QNX and VxWorks. Support for Maemo 5 is also currently in development, with the second technology preview being released today.

Qt support for Symbian and Maemo creates the first opportunity for developers to target both of these platforms from the same codebase. Being able to share code across platforms means that the applications they create will reach the market faster and reach a broader audience of device users.

Also released today is a technology preview of new Qt APIs from the Qt Mobility project. These cross-platform APIs provide developers with functionality such as location for navigation-type devices, as well as messaging, contacts, and bearer management.

More eye candy
Qt 4.6 builds upon the graphical improvements of 4.5 and enhances them with the addition of new Animation Framework – including intuitive state machine functionality – plus new advanced graphics effects like opacity, drop shadows, glow, and filtering.

More fingers
One of the most exciting new features in Qt 4.6 is the ability to create multi-touch applications. New multi-touch and gesture based input methods such as flicking and kinetic scrolling make Qt 4.6 a powerful framework for creating dynamic, tactile ways for users to interact with applications and devices.

More horsepower
Qt 4.6 challenges the conventional development notion that advanced UI capabilities normally come with a significant performance cost. Extensive work has been done to deliver the best possible performance while enabling developers to deliver the “wow” effect that is demanded by users.

Key performance improvements come in the form of a highly optimized, re-written Qt GraphicsView rendering algorithm, a new OpenGL paint engine, WebKit, 2D vector graphic support using OpenVG, and new DirectFB support.

Updated tools
Complimenting the release of Qt 4.6 is an updated release of Qt Creator, a cross-platform IDE for Qt development. Qt Creator 1.3 and Qt 4.6 form the Qt SDK which contains everything developers need to create cross-platform applications.

Espoo, Finland – Nokia today 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 Nokia 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.
“With this announcement and our upcoming port of Qt to the Symbian platform, we will quickly see Qt established as a leading framework for mobile application development. Developers will be able to use Qt as a framework to create powerful native applications and with Qt’s Webkit integration, it also provides them with a platform for creating web applications and services,” said Sebastian Nyström, Vice President of Application Services and Frameworks at Nokia. “Qt’s support for Maemo 5, Maemo 6, Symbian, as well as Windows Mobile makes Qt the most sensible choice for developers looking to target multiple devices and achieve the broadest reach with their innovations.”
This port of Qt will incorporate the community-driven ‘Qt for Maemo’ project that was created as result of substantial contributions and enhancements. The community project provided a strong foundation for building the official port, and because of the open nature of the project, Nokia was able to base the official port on this code. The change from a community port to an official port was necessary to ensure that applications developed with Qt will be compatible with both future versions of Qt, future versions of Maemo, as well as Symbian and the other platforms Qt supports.
Developers looking to support the Qt port Maemo to Maemo 5 are encouraged to visit http://qt.gitorious.org and participate in its further development. Since May 2009, Nokia has received over 400 contributions into Qt and Qt-related projects, which has helped ensure that Qt remains a stable, robust framework for developers to innovate on.
Developers looking to learn more about Qt 4.6 should visit http://qt.nokia.com, as a beta release of Qt 4.6, including the Symbian port, will be launched next week at the Qt Developer Days conference in Munich.
