Trolltech Releases Qt 4.1

December 19, 2005

Trolltech is pleased to announce the release of Qt 4.1, the latest version of its leading cross-platform development software. Qt 4.1 - the first feature release since Qt 4.0 - includes a wide range of performance and stability enhancements, as well a number functionality additions. Key features include:

  • Integrated support for rendering scalable vector graphics (SVG) drawings and animations, delivering compact, high fidelity images, independent of scale. Qt 4.1 supports Tiny profiles of SVG 1.1 and 1.2.
  • A PDF backend to the Qt printing system, making the creation of PDF files from both desktop and server applications as simple as printing
  • A lightweight unit testing framework that enables rapid, thread- and type-safe testing of Qt applications and libraries.

In addition to these key new features, Qt 4.1 introduces new functionality across the board. Additional new features include:

  • An interactive menu and action editor in Qt Designer, enabling drag-and-drop of actions into menus and toolbars
  • New proxy models to enable view-specific sorting and filtering of data displayed using item views
  • Expanded features for development with OpenGL, including support for pixel and sample buffers
  • A flexible syntax highlighting class added to the Qt text rendering framework
  • Improved integration with Microsoft Visual Studio .NET, including binaries for Visual Studio .NET 2005
  • Compatibility with other C++ libraries improved via 'no_keywords'- freely mix and even connect Qt Signals and Slots with Boost.Signals
  • Support for network proxy servers using the SOCKS5 protocol
  • Support for OLE verbs and MIME data handling in ActiveQt

Universal Binaries for Mac OS X

Available with Qt 4.1, improvements to qmake - Trolltech's cross-platform makefile build tool - now make it possible to create universal binaries for Mac OS X out of the box, enabling the creation of binaries that run on both Apple's PowerPC and new Intel architecture.
