<p>PURPOSE:To facilitate the application of a high-level graphic operation by providing each necessary object to the class objects including the graphic objects and the space relation objects and preparing the corresponding graphic operating procedures, etc., to those objects respectively. CONSTITUTION:An interface processing part 13 produces a desired window object 12 by the command information given from an input device 2 and uses this object 12 to execute the subsequent graphic operating instructions. Thus the graphic objects 10 and the space relation objects 11 are produced as desired. A graphic corresponding to the produced object 10 is displayed on a display device 3 as a composite graphic subject to the object 11 via the object 12. The object 12 identifies the indications of a cursor, etc., with respect to a displayed basic graphic and composite graphic based on the relative positions with areas and carries out a designating operation decided by an object to display this executing result on a display screen. Thus a high-level pattern processing system is obtained.</p> |
