FdcDataSetFieldChanged typedef

FdcDataSetFieldChanged = void Function(FdcDataSet dataSet, FdcFieldDef field, Object? oldValue, Object? newValue)

Called after a field value changes in the active edit buffer or through a direct field-level update operation.

This is a notification event only. It does not participate in the dataset abort/error lifecycle. If the handler changes another field, that nested change will raise its own FdcDataSetFieldChanged notification.

Implementation

typedef FdcDataSetFieldChanged =
    void Function(
      FdcDataSet dataSet,
      FdcFieldDef field,
      Object? oldValue,
      Object? newValue,
    );
