For more details, see the online +documentation which is included in this distribution. The +documentation is also available at http://doc.trolltech.com/ + +The Qt version 4.1 series is binary compatible with the 4.0.x series. +Applications compiled for 4.0 will continue to run with 4.1. + +**************************************************************************** +* General * +**************************************************************************** + +Qt library +---------- + +- Introduced widget backing store support, allowing semi-transparent + (alpha-blended) child widgets and faster widget painting, as well + as solving long-lasting issues with non-rectangular widgets. + +- Integrated support for rendering Scalable Vector Graphics (SVG) + drawings and animations (QtSvg module). + +- A Portable Document Format (PDF) backend for Qt's printing system. + +- A unit testing framework for Qt applications and libraries. + +- Modules for extending Qt Designer and dynamic user interface + building. + +- Additional features for developers using OpenGL, such as support + for pixel and sample buffers. + +- A flexible syntax highlighting class based on the Scribe rich text + framework. + +- Support for network proxy servers using the SOCKS5 protocol. + +- Support for OLE verbs and MIME data handling in ActiveQt. + +- Support for universal binaries on Mac OS X. + +Qt Designer +----------- + +- Added support for editing menu bars and tool bars. + +- Added support for adding comments to string properties. + +- Added new static QtUiTools library with improved + QUiLoader API for loading designer forms at run-time. + +- Added support for namespaces in uic generated code. + +- Added support for dock widgets in main windows. + +- Added support for editing table, tree and list widgets. + +- Improved palette editing and resource support. + +QTestLib +-------- + +- Added QTestLib, the Qt Unit Testing Library.
