gnome-libs has a function like this as well, iirc.
basically all child properties are captured, the container
is exchanged, and if possible, the recorded child properties
are re-set on the new container (at least those whose names/types
match the new container).
i doubt the general usefullness of this though, and have to say
that i never came across a situation where i _really_ needed
this functionality.
