PythonQt

Why is this project ?

This project is NOT the official PythonQt repository.

It is a fork of PythonQt sources hosted on sourceforge adding support for CMake build system.

It is used as staging area to maintain and test patches that will be contributed back to the official repository.

What is PythonQt ?

PythonQt is a dynamic Python binding for Qt. It offers an easy way to embed the Python scripting language into your Qt applications.

Which branch ?

Based on the Qt version your project is expected to support, you could use one of the branch referenced below:

Supported Qt version 4 5
Branch patched-6 patched-9
Base PythonQt revision r403 MeVisLab/pythonqt@c07f09fd

Build instructions

  1. Install CMake and Qt

  2. Checkout sources

git clone git://github.com/commontk/PythonQt.git
  1. Checkout branch
git checkout -b patched-X origin/patched-X

See table above for exact branch name

  1. Configure
mkdir PythonQt-build && cd PythonQt-build
  • using Qt4:
cmake -DQT_QMAKE_EXECUTABLE:FILEPATH=/path/to/qmake ../PythonQt
  • using Qt5:
cmake -DQt5_DIR:PATH=/path/to/Qt5.X.Y/X.Y/compiler/lib/cmake/Qt5 ../PythonQt
  1. Build
make

Additional configure options are:

  • CMAKE_BUILD_TYPE: Debug, Release, RelWithDebInfo or MinSizeRel
  • PythonQt_DEBUG: Enable/Disable PythonQt debug output
  • PythonQt_Wrap_QtAll: Make all Qt components available in python
  • PythonQt_Wrap_Qt<componentname>: Build a specific PythonQt wrapper.

Available branches

This repository contains 9 branches:

patched-9

  • Based on MeVisLab/pythonqt@c07f09fd with:
    • all changes from patched-8 cherry-picked expect:
      • Fix refcount problems seen when re-initializing Python after finalizing already integrated as MeVisLab/pythonqt@5e0d26c01ff (fixed ref counting of types)
      • Explicitly initialize global storage containers already integrated as MeVisLab/pythonqt@170d4a475 (reimplemented argument frame caching (previous approach was not thread-safe when GIL is used))
      • Expose QSocketNotifier for Qt5 already integrated as MeVisLab/pythonqt@518765494d (updated wrappers to contain QSocketNotifier and recent generator changes)
    • Add support for building 511 wrappers
    • Add support for QtMultimedia component
    • cmake: Add missing source file

patched-8

  • Based on r455 with:
    • revert of r444
    • all changes from patched-7 cherry-picked.
    • add support for build wrapping for Qml and Quick components
    • improve Qt5 support and remove Qt4 support
    • Remove explicit setup of INSTALL_NAME_DIR. See PR #59
    • add patch from @pieper fixing wrapping of QSocketNotifier (see PR#63 and message on PythonQt mailinglist)
    • Fix windows build error renaming stdout ivar
    • Add support for enabling stdout/stderr redirection
    • Fix setRedirectStdInCallbackEnabled

patched-7

  • Based on r443 with:
    • partial revert of r431 to re-enable CMake support
    • all changes from patched-6 cherry-picked.
    • add Qt5 support

patched-6

  • Remove explicit setup of INSTALL_NAME_DIR. Backported PR #59

    • Fix for memory leaks and cleanup crash
  • Includes the following PythonQt updates:
$ git shortlog 2d445d5..e93e36b --no-merges 
florianlink (8):
      fixed error handling for evalFile     made name->objectName alias optional (off by default, add PYTHONQT_SUPPORT_NAME_PROPERTY to DEFINES if you need it)     added py_delete() slot support for built-in delete() method
      added support for QTimer::singleShot()
      fixed a missign QMetaObject::disconnect which leads to connection leaking     added removeSignalHandlers()
      fixed test
      initial version that handles qualified virtual calls better
      improved handling of qualified virtual calls
      improved handling of qualified virtual calls
      removed generating wrappers for virtual functions that are already declared in a base class

patched-5

  • Based on patched-4 + r403 excluding commit r397
  • List of bug fixes:
    • Fix for memory leaks and cleanup crash
  • List of features:
    • CMake:
      • Fix install rules
      • Fix "_invalid_parameter_noinfo_noreturn" link error

      • Add Qt5 support
      • Add PY3K support

patched-4

  • Based on patched-3 + r245
  • List of features:
    • Add BUILD_TESTING option disabled by default to keep behavior consistent with previous version.
    • Do not exclude enums from wrapping if they are QFlags.
    • Ensure enums added using only Q_FLAGS without corresponding Q_ENUMS are wrapped.

patched-3

patched-2

  • Based on r228
  • List of features:
    • At configuration time, detect the Qt version used and seamlessly compile the appropriate wrappers (Qt 4.8, 4.7 or 4.6).
    • Add method allowing to know if a python error occurred: 5935f29
    • Also add associated method "resetErrorFlag": a386dc60
