Motif Programming With Xt

Course Length: 5 Days

Key Objectives

• Understand GUIs and how they are constructed.
• Understand the Client-Server model, and the event-driven nature of X applications.
• Develop and use GUIs using X library functions (Xlib).
• Learn how rubber-banding and other low-level GUI effects can be achieved in X.
• Understand the relationship between widgets, OSF/ Motif, the Xt intrinsics, and the X Window system.
• Learn the functionality of each of the Motif widgets.

Course Overview

This course combines the "X Window Programming" course and the "Motif Programming with Xt"course into a condensed 5 day course. It prepares the student to create OSF/Motif graphical user interfaces (GUI) using Motif and Xt, while also using lower level X function calls (Xlib) when necessary.

The course presents the essential elements of the X Window system, and continues through the Motif widget set and function libraries, along with the Xt toolkit intrinsics that are necessary to use them.

Students reinforce their understanding of the concepts by immediately applying them in hands-on exercises that build working X and Motif GUI applications.

Audience

The course is designed for programmers, engineers and managers who need to learn how to build efficient and effective GUIs using OSF/ Motif, but who also want to be able to use X window system features that are only available at the Xlib level.
