QDataWidgetMapper not writeable data
Message 1 in thread
I have a db table linked to the application using a
QSqlRelationalTableModel because there are 2 foreignk key fields and a
QDataWidgetMapper to map the form controls:
SqlTblModel.setTable("T_Machine");
SqlTblModel.setEditStrategy(QSqlRelationalTableModel::OnManualSubmit);
int iMachineTypeIndex = SqlTblModel.fieldIndex("idMachineType");
int iAttackTypeIndex = SqlTblModel.fieldIndex("idAttackType");
// these are foreign keys between T_Machine and other tables
SqlTblModel.setRelation(iMachineTypeIndex,
QSqlRelation("T_MachineType","idMachineType","Description"));
SqlTblModel.setRelation(iAttackTypeIndex,
QSqlRelation("T_AttackType","idAttackType","Description"));
SqlTblModel.select();
// data fields to widget controls mapping
// SqlDelegate = new QSqlRelationalDelegate(&Map);
Map.setModel(&SqlTblModel);
Map.setSubmitPolicy(QDataWidgetMapper::ManualSubmit);
apparently I am able to write data bat in practice the underlaying db
table doesn't change so I think I am missing something.
Every help welcome.
