TWideMemoField is the class used when a dataset must manage memo (Text BLOB) data. (TField.DataType equals ftWideMemo). It initializes some of the properties of the TField class. All methods to be able to work with widestring memo fields have been implemented in the TBlobField parent class.
It should never be necessary to create an instance of TWideMemoField manually, a field of this class will be instantiated automatically for each widestring memo field when a dataset is opened.
