I'm just guessing here, but it might be that the menu bar's events don't
get delivered to the QMainWindow.

Or, perhaps this documented caveat is important: "Note: Events are only
delivered to this event handler if the widget has a native window handle."

You might be able to catch the events if you
use QCoreApplication::installNativeEventFilter (
https://doc.qt.io/qt-6/qcoreapplication.html#installNativeEventFilter).
