Provides for interoperability between ABL GUI windows and .NET forms. All OpenEdge .NET
form-based classes in ABL implement this interface.
This interface does not contain method prototypes.
- There is no need for user-defined classes to implement this interface.
- For information on the use of this interface when working with the form chain in an
OpenEdge session, see OpenEdge Development: GUI for .NET Programming.
