I already found it. Question is how to make Qt work with it :-)

If I delete them, the parent may already have deleted them. So I'd have a double-delete.

I don't know. There's long call chains. Someone may delete the parent. There's no way to know.
Anyway, the question was whether Qt had something already in place. I now see I have to roll my own solution.
