+
+ A QSqlError object can provide database-specific error data,
+ including the driverText() and databaseText() messages (or both
+ concatenated together as text()), and the error number() and
+ type(). The functions all have setters so that you can create and
+ return QSqlError objects from your own classes, for example from
+ your own SQL drivers.
