-To use the modern and powerful Qt library, you need to install the PyQt6 package. To do this, call up the command Install //tools/install packages with PIP// via the GuiPy tools menu and enter //PyQt6// as the package name.
+To use the modern and powerful Qt library, you need to install the PyQt6 package. To do this, call up the command Install //tools/install packages with PIP// via the GuiPy tools menu and enter //PyQt6// as the package name. You can use the //pip list// command to display the list of currently installed packages.
-Alternatively, you can install the PySide6 package and replace PyQt6 with PySide6 in the Qt template. The Qt template can be found in the configuration under Editor/File templates.
+In addition, you should install the PySide6 package in order to be able to run source code based on it.
+One of the major changes in PyQt6 is the need to use fully qualified names for enums and flags. For example in PyQt5 and PySide2 you could just write Qt.DecorationRole or Qt.AlignLeft. This shortened form no longer works in PyQt6, you now have to write Qt.ItemDataRole.DisplayRole or Qt.Alignment.AlignLeft. This change affects all enums and flag types in Qt. Both long and short names are still supported in PySide6.
+If you prefer to work with the shortened forms, you can replace PyQt6 with PySide6 in the Qt template. The Qt template can be found in the configuration under Editor/File templates.
 Detailed information about Qt can be found in the [[https://doc.qt.io/qtforpython/PySide6/QtWidgets/index.html#module-PySide6.QtWidgets|documentation]] or [[https://doc.qt.io/qt-6/index.html|documentation Qt]].
