Documentation and Learning Materials

[https://www.riverbankcomputing.com/Docs/PyQt4/pyqt4ref.html Comprehensive documentation] is available for PyQt4 which includes detailed [https://www.riverbankcomputing.com/Docs/PyQt4/html/classes.html class and function documentation].

[https://www.diotavelli.net/PyQtWiki The PyQt and PyKDE Community Wiki] aims to provide tutorials and sample code for PyQt4.

An [https://indico.cern.ch/contributionDisplay.py?contribId=33&sessionId=41&confId=44 overview of PyQt4] was presented at EuroPython 2006.

An introduction to using [https://www.diotavelli.net/PyQtWiki/Creating_GUI_Applications_with_PyQt_and_Qt_Designer PyQt4 with Qt Designer] for the development of GUI applications was given at [https://www.pyconuk.org PyCon UK 2007].

The book [https://www.qtrac.eu/pyqtbook.html Rapid GUI Programming with Python and Qt] is PyQt4-specific and covers development with Python 2.5, PyQt4 and Qt 4.2/4.3.
