Answer 1

From another thread on Stack Overflow, I found this trick:

submenu->setStyleSheet("QMenu { menu-scrollable: 1; }");

For further information, see create a scrollbar in a submenu qt?

@Frank Osterfeld: I have a perfect example of a valid use case for huge contextual menu that needs a scrollbar, Qt Creator and the auto-completion list.
