Nokia Releases Qt 4.6
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.
form factor or platform,” said
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,” Nystrom added.
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
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.
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
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.
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
