ATU-203 : Building User Interfaces with Aonix TeleUSE

---

Course Description

This course lets developers master one of the most powerful features of Aonix TeleUSE is its Dialog Manager, which lets you specify, manage, and control the dynamic, or dialog, code that connects the GUI to the application code. You do so not through painstaking hard-coding of callbacks and events-although this option is available should you so choose-but rather by writing simple, object-oriented callback scripts that define the rules to be used when given events occur. The scripts are high-level abstractions of the X and Motif library routines. Ordinarily written from scratch, these scripts fully insulate you from the nuances and complexities of the underlying window system. They let you accomplish all the callbacks and event handling your application needs in a fraction of the time, and with a fraction of the instructions, required by direct low level coding. The course teaches you how at any time during development or maintenance, you can locate needed changes in moments and make those changes with a few keystrokes.
