  28
  29     For custom class implementors. Valid between MUIM_Setup/MUIM_Cleanup.
  30     Indicates that this object wants to receive some events. MUIM_HandleInput
  31     will then be called on this object whenever there's a matching event.

  35     obj   -- an object whose class is derived from Area
  36     flags -- IDCMP flags
