==Introduction==
[http://en.wikipedia.org/wiki/PySide PySide] is a Python binding of the cross-platform GUI toolkit Qt. FreeCAD uses PySide for all GUI (Graphic User Intercase) purposes. PySide evolved from the PyQt package which was previously used by FreeCAD for it's GUI. See [http://qt-project.org/wiki/Differences_Between_PySide_and_PyQt Differences Between PySide and PyQt] for more information on the differences.

Users of FreeCAD often achieve everything using the built-in interface. But for users who want to customise their operations then the Python interface exists which is documented in the [[Python_scripting_tutorial|Python Scripting Tutorial]]. The Python interface for FreeCAD had great flexibility and power. For it's user interaction Python with FreeCAD uses PySide, which is what is documented on this page.

== PySide in FreeCAD with Qt5 ==
Python offers the 'print' statement which gives the code:

FreeCAD was developed to be used with Python 2 and Qt4. As these two libraries became obsolete, FreeCAD transitioned to Python 3 and Qt5. In most cases this transition was done without needing to break backwards compatibility.

Normally, the {{incode|PySide}} module provides support for Qt4, while {{incode|PySide2}} provides support for Qt5. However, in FreeCAD, there is no need to use {{incode|PySide2}} directly, as a special {{incode|PySide}} module is included to handle Qt5.

This {{incode|PySide}} module is located in the {{incode|Ext/}} directory of an installation of FreeCAD compiled for Qt5.
{{Code|code=
/usr/share/freecad/Ext/PySide

This module just imports the necessary classes from {{incode|PySide2}}, but places them in the {{incode|PySide}} namespace. This means that in most cases the same code can be used with both Qt4 and Qt5, as long as it imports {{incode|PySide}}.

PySide in FreeCAD with Qt5

FreeCAD was developed to be used with Python 2 and Qt4. As these two libraries became obsolete, FreeCAD transitioned to Python 3 and Qt5. In most cases this transition was done without needing to break backwards compatibility.

Normally, the PySide module provides support for Qt4, while PySide2 provides support for Qt5. However, in FreeCAD, there is no need to use PySide2 directly, as a special PySide module is included to handle Qt5.

This PySide module is located in the Ext/ directory of an installation of FreeCAD compiled for Qt5. 

/usr/share/freecad/Ext/PySide

This module just imports the necessary classes from PySide2, but places them in the PySide namespace. This means that in most cases the same code can be used with both Qt4 and Qt5, as long as it imports PySide. 

PySide2.QtCore -> PySide.QtCore
PySide2.QtGui -> PySide.QtGui
PySide2.QtSvg -> PySide.QtSvg
PySide2.QtUiTools -> PySide.QtUiTools

The only unusual aspect is that the PySide2.QtWidgets classes are placed in the PySide.QtGui namespace. 

PySide2.QtWidgets.QCheckBox -> PySide.QtGui.QCheckBox
