I don't understand why the GType appears in the function call for
g_iter_next(). As I understand it, a GIter will always be used to
iterate on a single object, thus the GType should be a struct member
of its.

Thus you'd have something like the GtkTreeIter:

GIter foo;
foobar_get_iter (foo);
while (g_iter_has_next (foo)) {
  gpointer elt = g_iter_next (foo);
  ...
}
