Riverbank Computing is pleased to announce the release of PyQt v4.0beta1 available from http://www.riverbankcomputing.co.uk/pyqt/.
PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt (Windows, Linux and MacOS/X). Like Qt, PyQt is available under the GPL and a commercial license.
PyQt v4 supports Qt v4 (http://www.trolltech.com/products/qt/index.html).
PyQt v3 is still available to support earlier versions of Qt.
PyQt v4 is implemented as a set of 8 extension modules containing approximately 400 classes and 6,000 functions and methods.
QtCore The non-GUI infrastructure including event loops, threads, i8n, Unicode, signals and slots, user and application settings. QtGui A rich collection of GUI widgets. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. Includes an implementation of SQLite. QtSvg A set of classes to render SVG files onto Qt widgets. QtXML A set of classes that implement DOM and SAX parsers. QtAssistant A set of classes that enables the Qt Assistant online help browser to be integrated with an application.
A Windows installer is provided for the GPL version of PyQt to be used with the GPL version of Qt v4 (http://www.trolltech.com/download/qt/windows.html). It enabes a complete PyQt environment to be installed on Windows without the need for a C++ compiler.
PyQt includes the pyuic utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. It is also able to load Designer XML files dynamically.
