ANN: PyQt v4.6 Released

Discussion in 'Python' started by Phil Thompson, Sep 27, 2009.

  1. PyQt v4.6 has been released and is available from
    http://www.riverbankcomputing.com/software/pyqt/.

    PyQt is a comprehensive set of bindings for the Qt application and UI
    framework from Nokia. It supports the same platforms as Qt (Windows,
    Linux and MacOS/X).

    PyQt supports Python v3 and Python v2.3 and later.

    The highlights of this release include:

    - alternate, more Pythonic, APIs have been implemented for QDate,
    QDateTime, QString, QTextStream, QTime, QUrl and QVariant. Applications
    may select a particular API. By default Python v3 uses the new versions
    and Python v2 uses the old versions

    - Qt properties can be initialised, and signals connected using keyword
    arguments passed when creating an instance. Properties and signals can
    also be set using the QObject.pyqtConfigure() method.

    Windows installers are provided for the GPL version of PyQt which contains
    everything needed for PyQt development (including Qt, Qt Designer and
    QScintilla) except Python itself.

    PyQt v4 is implemented as a set of 18 extension modules containing over
    400 classes and over 6,000 functions and methods.

    QtCore
    The non-GUI infrastructure including event loops, threads, i18n,
    Unicode, signals and slots, user and application settings, mapped
    files and shared memory.

    QtDesigner
    A set of classes that allow the Qt Designer GUI design tool to be
    extended with PyQt.

    QtGui
    A rich collection of GUI widgets.

    QtHelp
    A set of classes for creating and viewing searchable documentation and
    being able to integrate online help with PyQt applications. It
    includes the C++ port of the Lucene text search engine.

    QtNetwork
    A set of classes to support TCP and UDP socket programming and higher
    level protocols (eg. HTTP, SSL).

    QtOpenGL
    A set of classes that allows PyOpenGL to render onto Qt widgets.

    QtScript
    A set of classes that implements a JavaScript interpreter. Python
    objects may be exposed in the interpreter as JavaScript objects.

    QtScriptTools
    A debugger for the JavaScript interpreter.

    QtSql
    A set of classes that implement SQL data models and interfaces to
    industry standard databases. The Windows installers include support
    for SQLite, MySQL, PostgreSQL and ODBC.

    QtSvg
    A set of classes to render SVG files onto Qt widgets.

    QtTest
    A set of classes to automate unit testing of PyQt applications and
    GUIs.

    QtWebKit
    This implements a web browser engine based on the WebKit engine used by
    Apple's Safari browser. It allows the methods and properties of Python
    objects to be published and appear as JavaScript objects to scripts
    embedded in HTML pages.

    QtXML
    A set of classes that implement DOM and SAX parsers.

    QtXMLPatterns
    A set of classes that implement XQuery and XPath support for XML and
    custom data models.

    QtAssistant
    A set of classes that enables the Qt Assistant online help browser to
    be integrated with an application.

    QAxContainer
    A set of classes for Windows that allows the integration of ActiveX
    controls and COM objects.

    phonon
    A cross-platform multimedia framework that enables the use of audio and
    video content in PyQt applications. DirectX is used as the Windows
    backend, QuickTime as the MacOS/X backend, and GStreamer as the Linux
    backend.

    DBus
    PyQt includes dbus.mainloop.qt that allows the Qt event loop to be used
    with the standard DBus Python bindings.

    PyQt includes the pyuic4 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.

    PyQt is available under the GPL and a commercial license. Unlike Qt, PyQt
    is not available under the LGPL. The commercial PyQt license allows GPL
    applications to be relicensed at any time.
