No, it says, "If no items accept the event, it will be ignored by the scene,
and propagate to the view..."

If just one item accepts the event, it will not be passed to the scene or
the view. If you accept an event, it does not propagate further. If you
are interested, the following documents will tell you all you need to know
about the event system in Qt:

Just accept the event in the item. Can you confirm that it does this? If it
does not behave this way, please report it as a bug via the Task Tracker:
