>from: klee@wsl.dec.com (Ken Lee)

This is the latest version of my bibliography of good X Window System technical
material.  There's alot of other stuff out there, but I think these are the
best references.  If you know of any other good ones, please let me know.

Many people have been asking questions about the bibliography.  No, I'm not
distributing it in any other format.  If your printer can't handle the UNIX-
style underlining, run it through the UNIX col filter or the equivalent on your
system.  Yes, I do accept (and appreciate) review copies of material.  Yes, you
may put copies of this in your books, but please let me know and include the
date and contact info from the header.  Updates to this bibliography will be
sent to comp.windows.x USENET group and xpert mailing list and placed in:
    expo:/contrib/Xbibliography and
    gatekeeper.dec.com:/archive/pub/X11/contrib/Xbibliography
approximately once a month.  Please do not ask me for updates other than these.

Sorry, I am not able to distribute copies of the material mentioned here.  Your
librarian or bookstore should be able to help you.

Heller, Dan, "The XView Toolkit (2 parts)," _U_N_I_X _R_e_v_i_e_w, vol. 7, no. 6-7,
     June-July, 1990.  A two part tutorial on XView, presumably based on
     Volume 7 of the O'Reilly series. XView is a user interface toolkit for

     York, 1986.  ISBN 0-387-16116-3.  The proceedings of the important
     1985 Alvey Workshop on Window Management. It includes interesting ma-
     terial on problems with UNIX window systems and proposed solutions. It
     also includes descriptions of early versions of current UNIX window
     systems, such as X and Sun's NeWS.

Johnson, Eric and Kevin Reichard, _X _W_i_n_d_o_w _A_p_p_l_i_c_a_t_i_o_n_s _P_r_o_g_r_a_m_m_i_n_g, MIS:
     Press, 1989.  ISBN 1-55828-016-2. Another tutorial on Xlib program-
     ming. This book has lots and lots of examples, but coverage of complex
     subjects is not as deep as Jones' book or as broad as the O'Reilly
     Xlib tutorial. Unfortunately, many of the example programs are not
     well behaved, so be careful.

Johnson, Eric and Kevin Reichard, _A_d_v_a_n_c_e_d _X _W_i_n_d_o_w _A_p_p_l_i_c_a_t_i_o_n_s _P_r_o_g_r_a_m_-
     _m_i_n_g, MIS: Press, 1990 An "advanced" version of the authors' previous
     book. Only Xlib programming is convered. The X11R4 ICCCM section is
     good, but, aside from that, this isn't much advanced over Oliver Jones
     book..  ISBN 1-55828-016-2.

Jones, Oliver, _I_n_t_r_o_d_u_c_t_i_o_n _t_o _t_h_e _X _W_i_n_d_o_w _S_y_s_t_e_m, Prentice-Hall, 1988,
     1989.  ISBN 0-13-499997-5. An excellent introduction to programming
     with Xlib.  Written with the programmer in mind, this book includes
     many practical tips that are not found anywhere else. This book is not
     as broad as the O'Reilly Xlib tutorial and doesn't offer as many exam-
     ples as the Johnson & Reichard book, but Jones is probably the most
     experienced X programmer of this group and this shows in the quality
     and depth of the material in the book. Originally written for X11R1,
     recent printings have included corrections and additions.  The sixth
     printing should have X11R4 material.

     mer, 1990.  An overview of Display PostScript, an extension to the X
     protocol allowing PostScript graphics in X windows.

Leffler, Samuel J., "A Window On The Future?," _U_N_I_X _R_e_v_i_e_w, vol. 6, no. 6,
     pp. 62-69.  This article compares Sun's NeWS with other window sys-
     tems, such as X, and concludes that, despite its problems, NeWS is the
     window system of the future. See Robin Schaufler's paper for a more
     technical comparison of the X and NeWS.

     torial on ``visuals'', the X abstraction of display hardware capabili-
     ties. Proper use of visuals is necessary for an X client to take ad-
     vantage of the capabilities of a server's hardware. Included in the
     MIT X distribution (X11R4/doc/tutorials/visuals).

     February, 1989.  Describes the InterViews user interface toolkit,
     written in C++ and based on the X Window System.  Even if you don't
     plan to use InterViews as a toolkit, it provides a good C++ binding to
     the X protocol.

     13.  An excellent tutorial on writing basic X Toolkit widgets.  Poten-
     tial widget writers (and maybe users, too) should probably start by
     reading this paper. Unfortunately, it's based on X11R2, so some of it
     is out of date.

     is a new tutorial on the X Toolkit intrinsics (Xt). Volume 6 (not yet
     available) will cover various widget sets, including OSF/Motif, AT&T
     Open Look, MIT Athena, etc.). Volume 7 (by Dan Heller) is a tutorial
     on XView, a toolkit similar to, but not compatible with, the X Toolk-
     it. These books are often not as deep as some of the others, but, un-
     like some of the others, they try to cover all of the functionality.
     Mostly written/edited by technical writers rather than engineers, they
     are probably the most professional looking of the X books. They books
     are updated regularly, with the most recent versions of some of them
     updated to X11R4.
