Abstract	Structural active-object systems (SAOSs) are transition-based object-oriented systems suitable as frameworks of various concurrent systems. AOSs are constructed from their component active objects by structural and hierarchical object composition (SHOC) like hardware systems. 1n this report, we demonstrate that the SAOS approach is effective in implementing a graphical editor. The SAOS Drawing Editor (SADE) is a SAOS program to aid creation of SAOS components, allowing its user to create, manipulate, and save graphical objects, which may be compound objects as well as such primitive objects as rectangles, lines, and ellipses. The implementation of SADE was simplified as structural active objects (SAOs) were used as its components including the canvas and the palette. Furthermore, since the graphical objects placed on the canvas are also SAOs, they can handle edit-operations for themselves. Keywords and Phrases: graphical editor, object-oriented programming, active-object system, structural composition, hierarchical composition, graphical user interface, compound object 1993 best estimate for issue date based on available information.
