A class hierarchy is presented by the abstraction of the basic graphic objects of the process flow chart. By applying above-mentioned model, an essential method of establishing custom object is described on the basis of ARX programming environment. Some key techniques are solved, which include entity display, text processing in compressed state and notification mechanism among objects.
