Nokia Releases New Qt Developer Offerings to Increase Productivity and Performance
announced the availability of version 4.5 of the Qt cross-platform
application and UI framework. It also introduced Qt Creator, a new
lightweight cross-platform Integrated Development Environment (IDE), Qt 4.5
and Qt Creator combined comprises the Qt SDK, an easy to install package that
will let developers create applications quickly and easily.
“Qt 4.5 is setting the benchmark for application development,” said
performance improvements in Qt, the introduction of Qt Creator, and the
release of the Qt SDK, developers looking for a native or a hybrid native/web
application framework now have the power and flexibility they need.”
The release of Qt 4.5 also marks an important milestone for the open
source community. For the first time Qt will include the LGPL licensing
option to go along with the Commercial License and GPL licensing options
currently available. By adding the LGPL license for Qt, developers can now
add their proprietary applications on top of Qt without paying a licensing
In addition to the new product releases and licensing changes, Qt
Software is also introducing a new flexible technical support package for
LGPL and GPL license users. Developers using these licenses will now be able
to purchase technical support from Qt Software.
Qt 4.5 includes several new features, but sees the greatest improvement
via a concerted effort to increase performance across the entire framework.
Significant performance enhancements were made to the graphics system, data
handling, and the web engine. These improvements result in an appreciable
performance increase in Qt-based applications.
Qt 4.5 also improves integration with the WebKit web rendering engine
which will blend web and native content into a richer user experience. This
Qt 4.5 has also been ported to Apple’s Cocoa framework. Previously Qt
supported only the Carbon framework, but with Qt 4.5, Qt can now support
both. This means developers can create applications that support 32 or 64
bit, Intel or PowerPC Mac binaries from a single source.
Developers can now download version 1.0 of Qt Creator, a lightweight
cross-platform IDE for Qt development. Qt Creator has been designed to
deliver two key benefits: it provides the first IDE designed specifically for
cross-platform development; and it enables developers that are new to the Qt
framework to get up and running more quickly.
Qt Creator includes an efficient tool set for creating and testing
Qt-based applications, including:
- An advanced C++ code editor - Context sensitive help system - Visual debugger - Source code management - Project and build management tools
Qt Creator will be available under the terms of the LGPL version 2.1
license and will be open for contributions. Currently Qt Creator only
supports desktop platforms for Qt development (Windows, Linux, and Mac OS),
however support for embedded platforms will be added in the coming months.
The Qt SDK
The new Qt SDK, downloadable from www.qtsoftware.com, is a comprehensive
package designed to provide developers everything they need to begin
cross-platform Qt development from a simple-to-install binary package.
The Qt SDK includes the Qt libraries, the Qt Creator IDE, and the Qt
tools, all integrated into one easy-to-install package. It has been tailored
to the needs of cross-platform developers and is designed to make new Qt
developers more productive, more quickly.
Contribute to Qt
In the coming weeks, Qt Software will be launching the Qt Contribution
website where developers will be able to see the Qt code repository and also
be able to contribute to Qt, Qt Creator and other Qt-related development
projects. More details will be announced soon.
Qt is a cross-platform application framework. Using Qt, you can develop
applications and user interfaces once, and deploy them across many desktop
and embedded operating systems without rewriting the source code. Qt
Software, formerly Trolltech, was acquired by Nokia in
