Once programmers have mastered the concepts behind X and learned how to program in Xlib and Xt there is still a mass of details to remember."The X Window System in a Nutshell fills this gap. Experienced X programmers can use this single-volume desktop companion for most common questions, keeping the full X Window System series of manuals for detailed reference."X in a Nutshell contains essential information in a boiled-down, quick-reference format that makes it easy to find the answers needed most often:Command line options and resources for the standard MIT X clients.Calling sequence for all Xlib and Xt functions and macros.Detailed description of structures, enums, and other X data types used as arguments or return values in Xlib or Xt functions.Description of the code inside a basic widget.Quick reference to the event structures.Font name syntax, color names, resource file and translations table syntax, and cursors.This book has been updated to cover R5, but is still useful for R4.
