Good day friends!

I'm trying to customize a QTableView through QItemDelegate. Trying debug noticed that my class MyDelegate is not being processed. I ask: Is it possible to delegate with QSqlQueryModel? What may be occurring's wrong? Follow my code:

Qt Code: 
  1. void CadComissoes::getUsuarios()
  2. {
  3. 	OpenDB();
  4. 	QSqlQuery qry;
  5. 	QString SQL;
  6.  
  7. 	model = new QSqlQueryModel();
  8.  
  9. 	SQL = "SELECT COD_USER, NAME, COD_GROUP ";
  10. 	SQL+= "FROM USERS";
  11.  
  12. 	qry.prepare(SQL);
  13. 	qry.exec();
  14.  
  15. 	model->setQuery(qry);
  16. 	ui.tableView_ComissaoUsuarios->setModel(model);
  17.  
  18. 	MyDelegate *iDelegate = new MyDelegate(this);
  19. 	ui.tableView_ComissaoUsuarios->setItemDelegate(iDelegate);
  20. 	CloseDB();
  21. }
  22.  
  23. MyDelegate::MyDelegate(QObject *parent)
  24. 	:QItemDelegate(parent)
  25. {
  26.  
  27. }
  28.  
  29. QWidget *MyDelegate::createEditor(QWidget *parent,
  30. 								   const QStyleOptionViewItem &option,
  31. 								   const QModelIndex &index) const
  32. {
  33. 	if (!index.isValid())
  34. 	{
  35. 		qDebug() << "Not Valid index";
  36. 	}
  37. 	if (index.column() == 2)
  38. 	{
  39. 		QSpinBox *editor = new QSpinBox(parent);
  40. 		editor->setMinimum(0);
  41. 		editor->setMaximum(100);
  42. 		return editor;
  43. 	}
  44. }
  45.  
  46. void MyDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
  47. {
  48. 	int value = index.model()->data(index, Qt::DisplayRole).toInt();
  49.  
  50. 	QSpinBox *spinBox = static_cast<QSpinBox*>(editor);
  51. 	spinBox->setValue(value);
  52. }
  53.  
  54. void MyDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
  55. 							   const QModelIndex &index) const
  56. {
  57. 	QSpinBox *spinBox = static_cast<QSpinBox*>(editor);
  58. 	spinBox->interpretText();
  59. 	int value = spinBox->value();
  60.  
  61. 	model->setData(index, value, Qt::EditRole);
  62. }
