Course Description: This hands on X/Motif programming course presents Motif GUI implementation using the X Window toolkit intrinsics along with Xlib and Motif function library calls, with an emphasis on event-driven programming. The extensive hands on exercises are hierarchically structured to build complex skills in a very short time. The course provides a thorough introduction to the Xt toolkit functions used in application programming, including those used for managing resources, handling events, and manipulating widgets. Students will learn how to effectively utilize primitive, manager, and shell widgets from the Motif library. Special emphasis is placed on designing for good interactive response and adhering to proper Motif style. Students also receive extensive practice using the Xlib application programming interface for window management, graphics and text display, event handling, interprocess communication, colormap creation and control, pixmap creation and management, and image processing. Use of UIL as well as C is integrated throughout, both as a learning tool and as an application development and prototyping skill useful after the class. Students will take home a versatile set of X/Motif clients to use as templates for their own work.
