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.
