delegate isn't work with QSqlTableModel?

Hi,

I have:

Code:

---

QSqlTableModel *model = new QSqlTableModel();
    model->setTable( "table" );
    model->select();
    model->setHeaderData( 0, Qt::Horizontal, QObject::tr("Annual Pay") );
    model->setHeaderData( 1, Qt::Horizontal, QObject::tr("First Name") );
    model->setHeaderData( 2, Qt::Horizontal, QObject::tr("Last Name") );
    model->removeColumn( 0 );
    TableResult->setModel( model );
    BarDelegate delegate;
    TableResult->setItemDelegateForColumn(1, &delegate);
    TableResult->show();

---

and in Delegate class i've:

Code:

---

class BarDelegate : public QAbstractItemDelegate
{
public:
  BarDelegate( QObject *parent = 0 );
 
  void paint( QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index ) const;
  QSize sizeHint( const QStyleOptionViewItem &option, const QModelIndex &index ) const;
 
  QWidget *createEditor( QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index ) const;
  void setEditorData( QWidget *editor, const QModelIndex &index ) const;
  void setModelData( QWidget *editor, QAbstractItemModel *model, const QModelIndex &index ) const;
  void updateEditorGeometry( QWidget *editor, const QStyleOptionViewItem &option, const QModelIndex &index ) const;
};

---

In createEditor:

Code:

---

QWidget *BarDelegate::createEditor( QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index ) const
{
    QMessageBox::information( 0, "window1", "test" );
  QLineEdit *lineEdit = new QLineEdit( parent );
  lineEdit->setAutoFillBackground( true );
  lineEdit->installEventFilter( const_cast<BarDelegate*>(this) );
  return lineEdit;
}

---

When I press on a cell TableResult, there is no QMessageBox :/

Similar with:

Code:

---

void BarDelegate::setEditorData( QWidget *editor, const QModelIndex &index ) const
{
    QMessageBox::information( 0, "window1", "test2" );
  QString value = index.model()->data( index, Qt::DisplayRole ).toString();
  static_cast<QLineEdit*>( editor )->setText( value );
}

---

and :/

Code:

---

void BarDelegate::setModelData( QWidget *editor, QAbstractItemModel *model, const QModelIndex &index ) const
{
    QMessageBox::information( 0, "window1", "test3" );
  model->setData( index, static_cast<QLineEdit*>( editor )->text() );
}

---

You cannot instantiate the delegate on the stack. You must instantiate it on the heap instead:

Code:

---

BarDelegate *delegate = new BarDelegate(this);
TableResult->setItemDelegateForColumn(1, delegate);

Thanks! Work!
