Motif Programming With Xt

Course Length: 5 Days

Key Objectives

• Understand the relationship between widgets, OSF/ Motif, the Xt intrinsics, and the X Window System.
• Learn the functionality of each of the Motif widgets.
• Learn how to build GUIs using the Motif widget set.
• Gain hands-on experience with OSF/Motif and Xt programming.

Course Overview
