Covering X11 Release 5, the Xlib Programming Manual is a complete guide to programming the X library (Xlib), the lowest level of programming interface to X. It includes introductions to internationalization, device-independent color, font service, and scalable fonts. Includes chapters on: X Window System concepts A simple client application Window attributes The graphics context Graphics in practice Color Events Interclient communication Internationalization The Resource Manager A complete client application Window management This manual is a companion to Volume 2, Xlib Reference Manual.

Orients the new user to Window system concepts and provides detailed tutorials for many client programs, including the xterm terminal emulator and window managers. This popular manual is available in two editions, one for users of the MIT software, one for users of Motif. Revised for X11 Release 5 and Motif 1.2.

Volume 4 is a complete guide to programming with the X Toolkit Intrinsics, the library of C language routines that facilitates the design of user interfaces with reusable components called widgets. It provides concepts and examples that show how to use the various X Toolkit routines. The first few chapters are devoted to using widgets; the remainder of the book covers the more complex task of writing new widgets. Uses the Motif 1.2 widget set in examples and covers X11 Release 5. Volume 4 includes: Introduction to the X Window System. Building applications with widgets. Constructing a bitmap editor with widgets. An overview of each widget in the widget set. Basic widget methods./li> Events, translations, and accelerators. Event handlers, timeouts, and work procedures. Resource management and type conversion. Selections and window manager interaction. Geometry management. Menus, gadgets, and cascaded pop-ups. Miscellaneous techniques. Comparison of Athena, OSF/Motif, and AT&T OPEN LOOK widgets. This book is designed to be used with Volume 5, X Toolkit Intrinsics Reference Manual, which provides reference pages for each of the Xt functions, the widget classes defined by Xt, and the Athena widget set.

An overview of the X Window System is presented, focusing on the system substrate and the low-level facilities provided to build applications and to manage the desktop. The system provides high-performance, high-level, device-independent graphics. A hierarchy of resizeable, overlapping windows allows a wide variety of application and user interfaces to be built easily. Network-transparent access to the display provides an important degree of functional separation, without significantly affecting performance, that is crucial to building applications for a distributed environment. To a reasonable extent, desktop management can be custom tailored to individual environments, without modifying the base system and typically without affecting applications.
