{{Note|PySide|Recently, FreeCAD has switched internally to use [http://qt-project.org/wiki/PySide PySide] instead of PyQt. That change was mainly done because of the licenses, PySide having an LGPL license which is more compatible with FreeeCAD. Other than that, PySide works exactly the same way as PyQt, and in FreeCAD you can usually use any of them, as you prefer. If you choose to use PySide, just replace all "PyQt" in the example code below with "PySide". See [http://qt-project.org/wiki/Differences_Between_PySide_and_PyQt Differences Between PySide and PyQt]}}

==Introduction==
[http://ru.wikipedia.org/wiki/PyQt PyQt] это модуль python, который позволяет приложениям на python создавать, получать доступ и изменять [http://ru.wikipedia.org/wiki/Qt Qt] приложения. Вы можете использовать его для создания собственных Qt программ на python, или получать доступ и изменять интерфейс запущенного qt приложения, такого как FreeCAD.

By using the PyQt module from inside FreeCAD, you have therefore full control over its interface. You can for example:

== PySide in FreeCAD with Qt5 ==
PyQt has an extensive [http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/classes.html API documentation], and there are many tutorials on the net to teach you how it works.


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.
If you want to work on the FreeCAD interface, the very first thing to do is create a reference to the FreeCAD main window:

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=
{{Code|code=
/usr/share/freecad/Ext/PySide
import sys
from PySide import QtGui ,QtCore
app = QtGui.qApp
mw = app.activeWindow()
}}
}}

Then, you can for example browse through all the widgets of the interface:
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}}.
{{Code|code=
{{Code|code=
PySide2.QtCore -> PySide.QtCore
for child in mw.children():
PySide2.QtGui -> PySide.QtGui
print 'widget name = ', child.objectName(), ', widget type = ', child
PySide2.QtSvg -> PySide.QtSvg
PySide2.QtUiTools -> PySide.QtUiTools
}}
}}
The widgets in a Qt interface are usually nested into "containers" widgets, so the children of our main window can themselves contain other children. Depending on the widget type, there are a lot of things you can do. Check the API documentation to see what is possible.


The only unusual aspect is that the {{incode|PySide2.QtWidgets}} classes are placed in the {{incode|PySide.QtGui}} namespace.
Adding a new widget, for example a dockWidget (which can be placed in one of FreeCAD's side panels) is easy:
{{Code|code=
{{Code|code=
PySide2.QtWidgets.QCheckBox -> PySide.QtGui.QCheckBox
myWidget = QtGui.QDockWidget()
mw.addDockWidget(QtCore.Qt.RightDockWidgetArea,myWidget)
}}
}}
You could then add stuff directly to your widget:
{{Code|code=
myWidget.setObjectName("my Nice New Widget")
myWidget.resize(QtCore.QSize(300,100)) # sets size of the widget
label = QtGui.QLabel("Hello World", myWidget) # creates a label
label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size
label.setObjectName("myLabel") # sets its name, so it can be found by name
}}
But a preferred method is to create a UI object which will do all of the setup of your widget at once. The big advantage is that such an UI object can be [[Dialog creation|created graphically]] with the Qt Designer program. A typical object generated by Qt Designer is like this:
{{Code|code=
class myWidget_Ui(object):
def setupUi(self, myWidget):
myWidget.setObjectName("my Nice New Widget")
myWidget.resize(QtCore.QSize(300,100).expandedTo(myWidget.minimumSizeHint())) # sets size of the widget


== PySide information ==
self.label = QtGui.QLabel(myWidget) # creates a label
self.label.setGeometry(QtCore.QRect(50,50,200,24)) # sets its size
self.label.setObjectName("label") # sets its name, so it can be found by name


Пользователи FreeCAD часто добиваются всего, используя встроенный интерфейс. Но для пользователей, которые хотят настроить свои операции, существует интерфейс Python, который описан в [[Python_scripting_tutorial | Python Scripting Tutorial]]. Интерфейс Python для FreeCAD обладает большой гибкостью и мощью. Для взаимодействия с пользователем Python с FreeCAD использует PySide, что описано на этой странице.
def retranslateUi(self, draftToolbar): # built-in QT function that manages translations of widgets

myWidget.setWindowTitle(QtGui.QApplication.translate("myWidget", "My Widget", None, QtGui.QApplication.UnicodeUTF8))
Python предлагает оператор 'print', который дает код:
self.label.setText(QtGui.QApplication.translate("myWidget", "Welcome to my new widget!", None, QtGui.QApplication.UnicodeUTF8))
}}
To use it, you just need to apply it to your freshly created widget like this:
{{Code|code=
{{Code|code=
print 'Hello World'
app = QtGui.qApp
FCmw = app.activeWindow()
myNewFreeCADWidget = QtGui.QDockWidget() # create a new dckwidget
myNewFreeCADWidget.ui = myWidget_Ui() # load the Ui script
myNewFreeCADWidget.ui.setupUi(myNewFreeCADWidget) # setup the ui
FCmw.addDockWidget(QtCore.Qt.RightDockWidgetArea,myNewFreeCADWidget) # add the widget to the main window
}}
}}
С оператором 'print' Python вы имеете только ограниченный контроль над внешним видом и поведением. PySide предоставляет отсутствующий элемент управления, а также обрабатывает среды (такие как среда макрофайловых файлов FreeCAD), где встроенных средств Python недостаточно.

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

PySide information

Пользователи FreeCAD часто добиваются всего, используя встроенный интерфейс. Но для пользователей, которые хотят настроить свои операции, существует интерфейс Python, который описан в Python Scripting Tutorial. Интерфейс Python для FreeCAD обладает большой гибкостью и мощью. Для взаимодействия с пользователем Python с FreeCAD использует PySide, что описано на этой странице.

Python предлагает оператор 'print', который дает код:

print 'Hello World'

С оператором 'print' Python вы имеете только ограниченный контроль над внешним видом и поведением. PySide предоставляет отсутствующий элемент управления, а также обрабатывает среды (такие как среда макрофайловых файлов FreeCAD), где встроенных средств Python недостаточно.
