1382.0. "New Book on XToolkit Programming" by RICARD::LAWSON () Wed Sep 06 1989 10:16

Subject: New Book on X Toolkit Programming


Prentice-Hall, Inc. announces the publication of a book on the X 
Window System focusing on the X Toolkit:

   The X Window System: Applications and Programming with Xt 

   by Douglas Young.

The X Window System was developed by Robert W. Scheifler of M.I.T.'s
Laboratory for Computer Science and a host of other contributors.  
Current X development activities are being carried out under the 
auspices of the MIT X Consortium.

X is a network-transparent portable windowing system for engineering
workstations.  Because interactive applications written for X can run 
on a wide variety of hardware, X is gaining wide acceptance as a base 
window system.

Description and Contents of the Book:
-------------------------------------

This book is written for the professional application developer or student
who wishes to use X and the X Toolkit. It describes how to use the X
Toolkit, a high level toolkit for writing X-based applications. The X
Toolkit consists of two levels, the Xt Intrinsics and a set of user
interface components known as widgets. The book describes both the Xt
Intrinsics layer and a typical widget set. The book presents a unified view
of the X Window System, describing and demonstrating how to write
applications using both the X Toolkit layer (Xt Intrinsics + widgets) and
the lower-level Xlib C interface.  The book also discusses how to extend
the X Toolkit by writing new widgets.

The book relies heavily on examples, presenting and dissecting over 40
complete working programs. The book is 477 pages long, including an
extensive index and several appendixes containing reference material.

  Just a note.

    This book deals extensively with the HP Widget Set.  Not much good for
  DEC's widget set.

    For my info on books take a look at note 466 in the RDVAX::X conference.
