Hi All,
I have a little problem with my QtCode, perhaps u guys can help me to solve the problem and I'll very appreciate. In my code, I aim to put an empty code to the QTableView whereas the query is get from QSqlQueryModel. I tried with sqlQueryModel->insertRow(0);, but nothing happend in the table. Completely the code looks like this
Qt Code: 
  1. sqlQueryModel->setQuery("SELECT * FROM  x=a, y=b  where b.ID = 0AND (b.anotherid = a.anotherid )",sqlDatabase);
  2.         sqlQueryModel->setHeaderData(0,Qt::Horizontal,tr("1"));
  3.         sqlQueryModel->setHeaderData(1,Qt::Horizontal,tr("2"));
  4.         sqlQueryModel->setHeaderData(2,Qt::Horizontal,tr("3"));
  5.  
  6.         ui->tableView->setModel(sqlQueryModel );
  7.         ui->tableView->setSelectionMode(QAbstractItemView::SingleSelection);
  8.         ui->tableView->setSelectionBehavior(QAbstractItemView::SelectRows);
  9.         ui->tableView->resizeColumnsToContents(); // resize column width depend to data cell
  10.         ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers); //unable edit through the cell
  11.         ui->tableView->verticalHeader()->setHidden(true);
  12.         ui->tableView->selectRow(0);
  13.  
  14.         header = ui->tableView->horizontalHeader();
  15.         header->setResizeMode(QHeaderView::Stretch);
  16.  
  17.         sqlQueryModel->insertRow(0);
