PySide

PySide is an open source sofware project providing Python bindings for the Qt framework. Qt is a cross-platform application and UI framework, allowing the developers to write applications once and deploy them across many operating systems without rewriting the source code, while Python is a modern, dynamic programming language with a vivid developer community.

Combining the power of Qt and Python, PySide provides the wealth of Qt framework for developers writing software in Python and presents a first-class rapid application development platform available on all major operating systems.

PySide consists of a full set of Qt and Qt Quick bindings for multiple platforms as well as the automated binding generation tools required to produce the bindings. Due to the availability of the whole toolchain, PySide will be of interest not only to developers requiring the Qt bindings, but to developers willing to generate other Qt and C++ based bindings as well.

Although based on a different technology than the existing GPL-licensed PyQt bindings, PySide maintains a high level of API-compatibility with them.

PySide aims to support all the platforms Qt itself does. Developers are encouraged to assist in porting the code to their platform of choice.
