Then why isn't it always?  I have found that I have to call create on
the children before the parent, in the few cases I have done this so
far.

OK, but how do I use this?  I mean, I realise my heuristic was
wrong, because the code works, but how do I revise it to fit with
reality? :-)  Are there whole families of widgets and windows for
which I can forget about the create() calls?  How do I look this
information up?
