Qt Code: 
  1. void Victims::load()
  2. {
  3. 	QAbstractItemModel* model = ui->tw->model();
  4. 	for(int row = 0; row < model->rowCount(); row++)
  5. 	{
  6. 		settings->beginGroup(QString("Row-%1").arg(row));
  7. 		for(int col = 0; col < model->columnCount(); col++)
  8. 		{
  9. 			settings->beginGroup(QString("Column-%1").arg(col));
  10. 			QModelIndex item = model->index(row, col);
  11. 			for(int role = 0; role < Qt::UserRole; role++)
  12. 			{
  13. 				model->setData(item, settings->value(QString("ItemDataRole-%1").arg(role))); // Restore from file
  14. 			}
  15. 			settings->endGroup();
  16. 		}
  17. 		settings->endGroup();
  18. 	}
  19. }
  20.  
  21.  
  22. void Victims::save()
  23. {
  24. 	QAbstractItemModel* model = ui->tw->model();
  25. 	for(int row = 0; row < model->rowCount(); row++)
  26. 	{
  27. 		settings->beginGroup(QString("Row-%1").arg(row));
  28. 		for(int col = 0; col < model->columnCount(); col++)
  29. 		{
  30. 			settings->beginGroup(QString("Column-%1").arg(col));
  31. 			QModelIndex item = model->index(row, col);
  32. 			for(int role = 0; role < Qt::UserRole; role++)
  33. 			{
  34. 				settings->setValue(QString("ItemDataRole-%1").arg(role), model->data(item, role)); // Save to file
  35. 			}
  36. 			settings->endGroup();
  37. 		}
  38. 		settings->endGroup();
  39. 	}
  40. }

Thanks for putting all this code.But the save slot doesn't work..after loading,the table is empty!!!!
