Porting applications from PySide2 to PySide6

Qt for Python 6.0.0 initially ships with the essential Modules and some add-ons (Qt Concurrent, Qt Help, Qt OpenGL, Qt Print Support Qt Quick Widgets, Qt SQL, Qt SVG, Qt UI Tools and Qt XML). More modules will follow in subsequent releases as they are added to Qt.

The first thing to do when porting applications is to replace the import statements:

from PySide2.QtWidgets import QApplication...
from PySide2 import QtCore

needs to be changed to:

from PySide6.QtWidgets import QApplication...
from PySide6 import QtCore

Some classes are in a different module now, for example QAction and QShortcut have been moved from QtWidgets to QtGui.

Then, the code base needs to be checked for usage of deprecated API and adapted accordingly. More information can be found in the Porting to Qt 6 Guide and the Qt 6.0 Documentation .
