Creating a Document Class

The primary function of a document class is to provide callbacks for requested data changes in a view, to handle user actions as relayed through associated views, and to tell associated views when data has been updated.

TDocument provides the framework for this functionality.

The programmer needs only to add the parts needed for a specific application of the document model.
