Context managers existed in Python since 2005 (PEP 343). They were invented to support resource management for different Python implementations that cannot rely on immediate object destruction. PyPy is the first alternate Python implementation that can run PySide. QPainter does not work in PyPy without an explicit end() call. For convenience, we supply a context manager that handles this. Like in file I/O, we now prefer instead of painter = QPainter(paintable) the new indented form with QPainter(paintable) as painter: [ChangeLog][PySide6] QPainter has become a context manager. Using a with statement saves the need to call painter.end() . Task-number: PYSIDE-535 Change-Id: Ib8bebbe121dc08334d31c9663a1e5bc8042c3b62 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@qt.io>
