Panel Editor Overview

The GUI ScreenIO panel editor is used to design your panels.

Its WYSIWYG (What You See Is What You Get) presentation makes it easy to create the look you want, plus you can execute the panel from within the editor to check out its tabbing sequence, etc., just as it will look and act when under control of your program.

Profiles

If you've never run the GUI ScreenIO panel editor before, go here learn how to set up an application profile. The profile establishes a number of defaults that are applied to new panels you create, and is required if you intend to take advantage of GUI ScreenIO's multiple language support.

You should also see Creating your First Panel for a quick introduction to using the GUI ScreenIO panel editor.

How panels are stored

GUI ScreenIO is document-centric; each of your panels is stored as a standard COBOL copybook.  Everything needed to edit or to run the panel is contained within the copybook.

The panel editor directly edits the panel copybook.

You should never modify the panel copybook using a text editor; always use the GUI ScreenIO panel editor. If you attempt to modify the copybook with a standard text editor you may corrupt the panel copybook.

Panel types

Panel Type Description
Main/Container The first panel that you display in your application must be a main panel. This panel copybook provides initialization settings to GUI ScreenIO and serves as a container for base panels.
Base A panel that occupies the entire client area of the container.  Only one base panel may be displayed at a time; if you display a different one, it simply replaces the one currently displayed.

Most applications would consist predominantly of base panels.

Popup A panel that appears to be in front of, or on top of, other panels.  A popup is not restricted to the bounds of your container and may be dragged anywhere on the screen.
Property Sheet A panel that is composed of two or more pages; you move from one page to another by clicking the tab of the desired page. 

GUI ScreenIO treats a property sheet as a regular panel; it handles all navigation from page-to-page automatically. 
Wizard A special case of property sheet that presents pages sequentially instead of allowing the user to select a page at will.
