1) you have a gboolean return and you specify NONE for your return, you
should have BOOLEAN there
2) Use OBJECT or POINTER instead of GTK_TYPE_ADJUSTMENT. These types are
used for the marshalling, and it is sufficient to pass objects as OBJECTs or
even just POINTERs. The type checking is done at a different place.
