Qt 4.5 Tech Preview Released

Qt Software has announced the release of a Technology Preview of Qt 4.5, the next major release of Qt, which is a C++, cross-platform framework for desktop and embedded applications development. Qt Software, formerly Trolltech (acquired by Nokia in June 2008), is now a unit of Nokia.

Qt is the development framework for the KDE desktop environment, and is also used in Google Earth, Skype for Linux, and Adobe Photoshop Elements. Qt is available to Java programmers through Qt Jambi.

Here’s some part of the news release:

The Technology Preview provides a first, complete look at new Qt features – all of which are aimed at achieving the three primary design goals for the Qt 4.5 release:

Improve the runtime performance of Qt-based applications
Qt 4.5 brings a new performance benchmarking library, focused re-engineering of key functionality, and a new pluggable graphics system – all aimed at increasing the performance of Qt-based applications. As most engineering work has been done to the core Qt API, in most cases Qt users need only to upgrade to Qt 4.5 to realize performance benefits immediately.

Allow Qt users to realize the full potential of WebKit
Qt integrates with the WebKit browser engine, and with Qt 4.5 that integration has been upgraded to utilize the latest version of WebKit. Qt users can now preview new Netscape plug in support – which allows developers to incorporate Flash™ content – added support for HTML 5, and integration with a new JavaScript engine, SquirrelFish.

Futureproof Qt users’ investments on the Mac® platform with added 64-bit support
Continuing the Qt tradition of insulating developers from platform-specific changes, Qt 4.5 adds support for developing 64-bit applications on top of the new Mac Cocoa API, making it possible for Qt developers to deploy resource-intensive applications to the latest version of the Mac OS (10.5).

Qt 4.5 Technology Preview is available for download under a dual license (commercial and open source) for all supported platforms – Linux/X11, Embedded Linux, Windows CE, Windows, Mac.
