PyQt

PyQt is a Pythonbinding of the cross-platformGUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the British firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including GNU General Public License (GPL) and commercial license, but not the GNU Lesser General Public License (LGPL). PyQt supports Microsoft Windows as well as various kinds of UNIX, including Linux and macOS.

PyQt implements around 440 classes and over 6,000 functions and methods including:

• a substantial set of GUI widgets
• classes for accessing SQLdatabases (ODBC, MySQL, PostgreSQL, Oracle, SQLite)
• QScintilla, Scintilla-based rich text editor widget
• data aware widgets that are automatically populated from a database
• an XMLparser
• SVG support
• classes for embedding ActiveX controls on Windows (only in commercial version)

To automatically generate these bindings, Phil Thompson developed the tool SIP, which is also used in other projects.
