      void onCallback(CallbackHandler __self)
      The type used for callback functions in structure definitions and function
      signatures.

      This doesn't mean that all callback functions must take no parameters and
      return void. The required signature of a callback function is determined by
      the context in which is used (e.g. the signal to which it is connected).

      Use G_CALLBACK() to cast the callback function to a #GCallback.
