Using Object Interfaces

A large part of creating applications with Progress is providing your users with computer displays that give them workspace to accomplish their tasks. All the displays you create add up to the application interface. An individual display in your interface consists of interface objects that are controls, representations of data, decorations, or containers. In Progress, these interface objects are known as widgets.

To create successful Progress interfaces, you need to successfully program widgets. This tutorial will teach you everything you need to know about programming widgets. However, as a first step, you need to know how to use widgets. If you are already familiar with the kind of interfaces that are made up of objects, then you can skip this section and continue with the next.

If you are new to object interfaces, access the on-line widget demonstration.

In the Procedure Editor:

  1. Enter the name of the on-line demonstration program. Because you have modified the PROPATH, you do not have to enter the entire absolute address. The following example shows how to enter this command on Windows:
  2. RUN widget.p. 
    

    NOTE: If you have not changed the PROPATH, enter:

    RUN c:\Progress\Wrk\prodoc\langtut\widget.p. 
    

  3. Press F2. to run the single-line program you have entered.
  4. The on-line Widget Tutorial appears:
  5. Follow the instructions you see on your display. You can press ESC at any time to end the on-line tutorial, and ESC again to return to the Procedure Editor.
