Multi-line editors

The Editor widget provides the ability to capture large amounts of text in a way familiar to and convenient for the user. You might use an editor object to capture, for example, free-form comments of undetermined length.

Although they are basic 4GL objects rather than SmartObjects, you can add a considerable amount of additional capability to them through calls to 4GL methods for searching, etc.
