X Windows Systems

X Windows Systems: Programming and Applications with Xt presents programming applications for the Xt Intrinsics and the various widget libraries. This approach to the X Window System enables the applications programmer to create easily and more efficiently the mouse-driven, graphical user interfaces.

Each one of the key features is illustrated with working programs, explanations, and pictures of the screen.

Additional highlights:

• Builds and uses a running library of useful functions. This encourages the design of reusable software.
• Contains over 40 working examples.
• Offers the described Xt Intrinsics and X Widget set software at no cost to those with ARPA net access.
• Contains 3 chapters that describe writing new widgets. Four complete widgets, designed just for the book, are presented and explained.
