This package provides improved typing stubs for Qt6 for Python/PySide6. The official stubs delivered along with PySide6 are insufficent for proper typing verification with mypy.

• add all missing signals to the stubs (many were missing)
• add conversion from QByteArray to bytes
• add construction of QByteArray from length and string
• fix QFileDialog.getOpen*() methods to accept None as parent argument
• fix QLineEdit.setText() to accept None
• fix QTreeWidget.setItemWidget() and QListWidget.setItemWidget() to accept None as a widget argument
• fix QProgressDialog.setCancelButton() accepting None
• support all QSize and QSizeF operations
• fix QTabBar.setButtonWidget() to accept None as a widget argument
• fix QTreeWidget.topLevelItem() returning possibly None
• fix QTreeWidgetItem comparison with <
• fix QMessageBox.warning, information, critical, question, about, aboutQt to accept None as parent argument
• fix qVersion() returns string, not bytes
• fix qDebug(), qWarning(), qCritical(), qFatal(), SIGNAL(), SLOT() to accept string, not bytes
• fix Signal.connect(), Signal.disconnect(), QObject.connect() and QObject.disconnect() to accept str instead of bool, and to return bool on disconnect.
• fix incorrect signature of QCoreApplication.translate()
• improve signature of operations on QPolygon

See CHANGELOG.md for full details.

This effort was inspired by the PyQt5-stubs and PySide2-stubs project.

Please note that this work is far from complete. Don't hesitate to report problems or propose improvements.

As a derived work from PySide6, the stubs are delivered under the LGPL v2.1 . See file LICENSE for more details.

Install from pypi:

$ pip install PySide6-stubs

If you want to install the stable development version from the Git repository:

If you notice incorrect or missing typing information (mypy reports errors eventhough your code is correct), please report it here with the following steps:

• create an issue showing your problem
• even better, create a PR to fix the problem. See CONTRIBUTING.md for details.
