No fields are read-write. As for the ones that are read-only, it is
basically a matter of tradition and necessity. Browsing through
gtkperl might prove useful, since I believe they have been added there
in a as-needed basis, which (except for documentation) is probably the
best way to do it. Just adding them randomly is not a good idea,
since, for instance, none of the fields you mention above is really
public.

(The two "public" ones that come up most often are toggle_button->active 
 and clist->selection)
