Hello Mildred,

I would like to get a one specific cell in the row. I use this solution:

 {
  QVariant variant
  QModelIndex index;
  int rownumber;
  QSqlQuery *query = new QSqlQuery;


  index = group_ui->tableView->currentIndex();
  rownumber = index.row();
  index = index.sibling(rownumber, 0); /* 0 is the code of id column */

  variant = index.data();

  query->prepare("delete from dsm_group where id = ?");

  query->addBindValue(variant.toString());
  query->exec();
  refrashTableView();
}

How you can see I use the method sibling that I can specific the row
and column. Did you understand ?

best regards,
