//-------------- connection settings-------------
 
deliveryModel = new QSqlRelationalTableModel(this);
deliveryModel->setTable("deliveries");
deliveryModel->select();
 
deliveryModel->setRelation(deliveryModel->fieldIndex("supplierid"), QSqlRelation("suppliers","id","name"));
deliveryModel->setRelation(deliveryModel->fieldIndex("productid"), QSqlRelation("products","id","name"));
deliveryModel->setRelation(deliveryModel->fieldIndex("tva"), QSqlRelation("tva","unity","type"));

deliveryModel->setEditStrategy(QSqlRelationalTableModel::OnManualSubmit);
 
 
 
ui->deliveryView->setModel(deliveryModel);
 
ui->deliveryView->setItemDelegate(new QSqlRelationalDelegate(this));
ui->deliveryView->setAlternatingRowColors(true);
ui->deliveryView->setCornerButtonEnabled(true);
 
ui->deliveryView->setSelectionMode(QAbstractItemView::SingleSelection);
ui->deliveryView->setSelectionBehavior(QAbstractItemView::SelectRows);
ui->deliveryView->setSortingEnabled(true);
ui->deliveryView->setEditTriggers(QAbstractItemView::NoEditTriggers);
ui->deliveryView->horizontalHeader()->setStretchLastSection(true);
ui->deliveryView->resizeColumnsToContents();
ui->deliveryView->setCurrentIndex(deliveryModel->index(0, 0));
 
ui->deliveryView->setColumnHidden(0/*Deliveries_Id*/, true);
