PySide

PySide è il legame tra Python e la multi-piattaforma GUI degli strumenti di Qt. FreeCAD usa PySide all'interno di Python per tutti gli effetti GUI (Interfaccia grafica per l'utente). PySide è una alternativa al pacchetto PyQt che è stato utilizzato in precedenza da FreeCAD per la sua GUI. PySide ha una licenza più permissiva. Per maggiori informazioni sulla differenza vedere Differences Between PySide and PyQt.

When you install FreeCAD, you should get both Qt and PySide as part of the package. If you are compiling yourself then you must verify that these two libraries are installed in order for FreeCAD to run correctly. Of course, PySide will only work if Qt is present.

In the past, FreeCAD used PyQt, another Qt binding for Python, but in 2013 (1dc122dc9a) the project migrated to PySide because it has a more permissible license.

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, and 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 we use the single PySide module.

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

Examples of PySide use

Per acquisire familiarità con alcuni esempi reali di PySide

Esempi di livello base di PySide (Hello World, avvisi, inserire un testo, inserire un numero)
Esempi di livello medio di PySide (dimensionare le finestre, nascondere i widget, i menu popup, la posizione del mouse, gli eventi del mouse)
Esempi di livello avanzato di PySide (widget etc.)

Esse suddividono l'argomento in 3 parti, e si differenziano per livello di esposizione per PySide, Python e le parti incorporate in FreeCAD. La prima pagina contiene una panoramica e le basi della materia, fornisce una descrizione di PySide e di come è organizzato, mentre la seconda e la terza pagina contengono soprattutto degli esempi di codice di diversi livelli.

Con le pagine allegate si intende fornire del semplice codice Python per eseguire PySide, in modo che l'utente possa facilmente copiarlo, incollarlo nel proprio lavoro, adattarlo se necessario, e risolvere i suoi problemi con FreeCAD. Sperando che non abbia bisogno di andare alla ricerca di risposte alle domande su PySide attraverso internet. Allo stesso tempo, queste pagine non vogliono sostituirsi ai vari tutorial completi e ai siti di riferimento a PySide presenti nel web.

Documentation

There are some differences in handling of widgets in Qt4 (PySide) and Qt5 (PySide2). The programmer should be aware of these incompatibilities, and should consult the official documentation if something doesn't seem to work as expected on a given platform. Nevertheless, Qt4 is considered obsolete, so most development should target Qt5 and Python 3.

The PySide documentation refers to the Python-style classes; however, since Qt is originally a C++ library, the same information should be available in the corresponding C++ reference.

Qt Modules available from PySide2 (Qt5).
All Qt classes by module in Qt5 for C++.

-[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==
+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
-print 'Hello World'
 }}
-With Python's print statement you have only limited control of the appearance and behaviour. PySide supplies the missing control and also handles environments (such as the FreeCAD macro file environment) where the built-in facilities of Python are not enough.
+This module just imports the necessary classes from {{incode|PySide2}}, and 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 we use the single {{incode|PySide}} module.
-PySide's abilities range from:

+==Documentation==
+There are some differences in handling of widgets in Qt4 (PySide) and Qt5 (PySide2). The programmer should be aware of these incompatibilities, and should consult the official documentation if something doesn't seem to work as expected on a given platform. Nevertheless, Qt4 is considered obsolete, so most development should target Qt5 and Python 3.
-They divide the subject matter into 3 parts, differentiated by level of exposure to PySide, Python and the FreeCAD internals. The first page has overview and background material giving a description of PySide and how it is put together while the second and third pages are mostly code examples at different levels.
+The PySide documentation refers to the Python-style classes; however, since Qt is originally a C++ library, the same information should be available in the corresponding C++ reference.
-The intention is that the associated pages will provide simple Python code to run PySide so that the user working on a problem can easily copy the code, paste it into their own work, adapt it as necessary and return to their problem solving with FreeCAD. Hopefully they don't have to go chasing off across the internet looking for answers to PySide questions. At the same time this page is not intended to replace the various comprehensive PySide tutorials and reference sites available on the web.
