I've used it to create a pattern, in which all access to children was
inside the class, but I could have additional parameters to the
constructor of that class.=20

I'm shocked. I'm doing nearly the same thing in my code, but using the
changes to glademm from my patch. This idea seems cleaner than mine,
because in my version I use a static factory function, and here just a
constructor is needed. I'll test this idea.
