GtkAdjustments is used in the virtual method as you can see in the
defs file (and later on in the generated C code)

(define-virtual set_scroll_adjustments
  (of-object "GooCanvas")
  (return-type "none")
  (parameters
    '("GtkAdjustment*" "hadjustment")
    '("GtkAdjustment*" "vadjustment")
  )
)

The generated code will use the format string "O!O!" when parsing
arguments, that means something like &PyGtkAdjustment_Type,
&hadjustment, &PyGtkAdjustment_Type, &vadjustment.
