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.
