TStringField is the class used whenever a dataset has to handle a string field type (data type ftString). This class overrides some of the standard TField methods to handle string data, and introduces some properties that are only pertinent for data fields of string type. It should never be necessary to create an instance of TStringField manually, a field of this class will be instantiated automatically for each string field when a dataset is opened.
