paintEvent(event)

See Qt documentation for method documentation

Note

The C++ paintEvent() and initStyleOption() methods won’t call a Python implementation of currentText() or initStyleOption(), presumably due to a bug in PyQt. To get around this, we reimplement the paintEvent() method in Python and force it to call the Python currentText() method
