If you really want to *remove* a menu entry simply deleting the corresponding QAction is enough: the QObject meta-system will automatically make sure that the given QObject (the QAction) is unregistered from its parents (aka "owners") which happens to the the QMenu. So the menu entry is removed for you.

If you want to *change* an existing menu entry you can use the usual QAction#setText() etc. method and disconnect/reconnect the QAction as needed.

Cheers, Oliver
