Preface
This manual describes the XView attributes, callbacks, procedures, macros, data structures,
as well as additional reference material. XView (X Window-System-based Visual/Integrated
Environment for Workstations) is a user-interface toolkit to support interactive, graphics-
based applications running under the X Window System. This toolkit, developed by Sun
Microsystems, Inc., is derived from earlier toolkits for the SunView windowing system.
With over 2000 SunView applications in the workstation market, there are many program-
mers already familiar with SunView application programmer’s interface (API).
XView is based upon Xlib, the lowest level of the X Window System available to the pro-
grammer. While developing XView user interfaces does not require Xlib programming expe-
rience, there are good reasons for learning more about Xlib, especially if your application
renders graphics.
