Description

Provides the interface for a method that can set the DataType for the field.

As implemented in TField, SetFieldType does nothing. Descendant classes override SetFieldType to set the DataType for the field component. SetFieldType is useful for derived classes that can support more than one underlying data type. For example, a TBlobField may support ftBlob, ftFmtMemo, ftParadoxOle, ftDBaseOle, or ftTypedBinary.
