PySide 1.1.2

Python bindings for the Qt cross-platform application and UI framework

Latest Version: 1.2.1

Introduction

PySide is the Python Qt bindings project, providing access the complete Qt 4.8 framework as well as to generator tools for rapidly generating bindings for any C++ libraries.

The PySide project is developed in the open, with all facilities you'd expect from any modern OSS project such as all code in a git repository [1], an open Bugzilla [2] for reporting bugs, and an open design process [3]. We welcome any contribution without requiring a transfer of copyright.

Compatibility

PySide requires Python 2.6 or later and Qt 4.6 or better.

Installation

Installing prerequisities

Install latest distribute distribution: download distribute_setup.py and run it using the python interpreter.

Installing PySide on a Windows System

There are two options to install PySide on Windows:

  1. Download and install the packages from the releases page.

  2. Use setuptools:

    c:\> c:\Python27\Scripts\easy_install PySide
    c:\> c:\Python27\python.exe c:\Python27\Scripts\pyside_postinstall.py -install
    

    Note that the post-install procedure is not needed when installing via installer. The installer calls the pyside_postinstall.py script automatically.

Installing PySide on a UNIX System

There are no prebuild setuptools distributions available for UNIX System. To build and install setuptools compatible distributions for UNIX System, please read the instructions in section Building PySide on a UNIX System.

Using pip vs easy_install

Pip can install only from source (it does not support binary distributions) and allways rebuilds the distribution before the distribution is installed to system. For that reason the recommended tool to install the PySide is easy_install.

Building PySide on a Windows System

Installing prerequisities

  1. Install Python.

  2. Install Qt 4.8 libraries for Windows (VS 2008).

  3. Install Cmake.

  4. Install Visual Studio Express 2008 when building against Python 2.6, 2.7 or 3.2. Install Visual Studio Express 2010 when building against Python 3.3.

  5. Install Git.

  6. (Optional) Install OpenSSL.

  7. Install latest distribute distribution into the Python you installed in the first step: download distribute_setup.py and run it using the python interpreter of your Python 2.7 installation using a command prompt:

    c:\> c:\Python27\python distribute_setup.py
    

Building PySide distribution

  1. Clone PySide setup scripts from git repository:

    c:\> git clone https://github.com/PySide/pyside-setup.git pyside-setup
    
  2. Switch to the pyside-setup directory:

    c:\> cd pyside-setup
    
  3. Build PySide windows installer:

    c:\> c:\Python27\python.exe setup.py bdist_wininst --qmake=c:\Qt\4.8.4\bin\qmake.exe --openssl=c:\OpenSSL32bit\bin
    
  4. Optionally you can specify the msvc compiler version:

    c:\> c:\Python27\python.exe setup.py bdist_wininst --msvc-version=10.0 --qmake=c:\Qt\4.8.4\bin\qmake.exe --openssl=c:\OpenSSL32bit\bin
    
  5. After the successful build, install the distribution with easy_install and run the post-install script:

    c:\> c:\Python27\Scripts\easy_install dist\PySide-1.1.2.win32-py2.7.exe
    c:\> c:\Python27\python.exe c:\Python27\Scripts\pyside_postinstall.py -install
    
    # After successfull install, the post-install script should print the following information to the console:
    
    c:\> The PySide extensions were successfully installed.
    

Building PySide on a UNIX System (Ubuntu 12.04 LTS)

Installing prerequisities

  1. Install Python 2.7 header files and a static library:

    $ sudo apt-get install python2.7-dev
    
  2. Install Qt 4.8 libraries:

    $ sudo apt-get install qt-sdk
    
  3. Install cmake:

    $ sudo apt-get install cmake
    
  4. Install git:

    $ sudo apt-get install git
    
  5. Install latest distribute distribution into the Python you installed in the first step: download distribute_setup.py and run it using the python interpreter of your Python 2.7 installation using a command prompt:

    $ sudo python2.7 distribute_setup.py
    

Building PySide distribution

  1. Clone PySide setup scripts from git repository:

    $ git clone https://github.com/PySide/pyside-setup.git pyside-setup
    
  2. Switch to the pyside-setup directory:

    $ cd pyside-setup
    
  3. Build PySide distribution:

    $ python2.7 setup.py bdist_egg
    
  4. Optionally you can build standalone version of distribution with embedded Qt libs:

    $ python2.7 setup.py bdist_egg --standalone
    
  5. After the successful build, install the distribution with easy_install and run the post-install script:

    $ sudo easy_install-2.7 dist/PySide-1.1.2.egg
    $ sudo python2.7 pyside_postinstall.py -install
    
    # After successfull install, the post-install script should print the following information to the console:
    
    $ PySide package successfully installed in...
    

PySide Setup Script command line options

Usage on Windows System

c:\> c:\Python27\python.exe setup.py [distribution_type] [options]

Usage on UNIX System

python2.7 setup.py [distribution_type] [options]

Distribution types

bdist_wininst
Create standalone windows installer with embedded Qt libs and development tools. This distribution type can be installed with easy_install.
bdist_egg
Create egg binary distribution. This distribution type can be installed with easy_install.
install
Install package to site packages folder.
develop
Install package in development mode, such that it's available on sys.path, yet can still be edited directly from its source folder.
sdist
Create full source distribution with included sources of PySide Setup Scripts, PySide, Shiboken, PySide Tools and PySide Examples. Can be used to build binary distribution in offline mode.

Options

--qmake
Specify the path to qmake. Useful when the qmake is not in path or more than one Qt versions are installed.
--openssl
Specify the path to OpenSSL libs.
--only-package
Skip rebuilding everything and create distribution from prebuilt binaries. Before using this option first time, the full distribution build is required.

--standalone
When enabled, all required Qt libs will be included in PySide distribution. This option is allways enabled on Windows System. On Linux it's disabled by default.
--version
Specify what version of PySide distribution to build. This option is available only when the setup scripts are cloned from git repository.
--list-versions
List available versions of PySide distributions.
--ignore-git
