This document provides the background material needed to understand 
the other documentation:
- The XPCE Reference Manual
 Wielemaker & 
Anjewierden, 1993 The reference manual is available by means 
of the Prolog predicate manpce/0 . The reference manual provides 
detailed descriptions of all classes, methods, etc. which may be 
accessed from various viewpoints. See also chapter 
3.
- PceDraw: An example of using XPCE
 Wielemaker, 
1992 This document contains the annotated sources of the 
drawing tool PceDraw. It illustrates the (graphical) functionality of XPCE 
and is useful as a source of examples.
- XPCE/Prolog Course Notes
 Wielemaker, 
1994 Course-notes, examples and exercises for programming XPCE/Prolog 
. The course-notes have a large overlap in contents with this user 
guide, but the material is more concise. If you are familiar with 
object-oriented systems, Prolog and graphical user interfaces the 
course-notes might be a quick alternative to this user guide.
