Well, I knew it was there ;)

One "messy" thing about GTK is that a lot of useful information is
conained in the widget structures.  People from the C++ world are use to
getting all information from class methods, and all varibles are private
to the class.  This isn't the case with GTK.  There's a lot to be with
regard to this, but I'm pretty neutral on the idea of providing a function
call for every "public" pice of information in a widget.  That's the kind
of decision that needs to be made and implimented on the entire toolkit.

The implimentation is more difficult than the decision though, a function
that returns the number of rows in a CList is trivial; but for a function
that returns a list of all the children in a container there are all kinds
of memory management issues involved with the returned list (ie, do we
just return the list that is actually used by the widget *dangrous*, or do
we allocate a new list *has to be freed by the user*).  I'd be worried it
would happen both ways and be confusing.
