Volume 4: X Toolkit Intrinsics Programming Manual: Standard Edition (Definitive Guides to the X Window System)

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.

Volume 4 is available in two editions. The Standard Edition uses Athena widgets in examples for X11 Release 5 to demonstrate how to use existing widgets, while still providing a good introduction to programming with any widget set based on Xt.

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.
• 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.
