how to get qstandarditem from qmodelindex using qitemdelegate (qabstractitemmodel)

I have a qstandarditemmodel and a qtableview but when using QItemDelegate to get QLineEdit editor I must declare QAbstractItemModel rather than QStandardItemModel when using Delegate::setModelData, thus I cannot use QstandardItem::itemFromIndex within the setModelData function of the delegate.

How can I get a QStandardItem from a QmodelIndex in this case?

Or how can I use the delegate with QStandardItemModel rather than QAbstractItemModel so that I can access model->itemFromIndex...

Code:

---

void Delegate::setModelData(QWidget * editor, QAbstractItemModel * model, const QModelIndex & index) const
{
 
 
    QStandardItem *item = model->itemFromIndex(index); //itemFromIndex does not exist in this context!

---

I am afraid I don't understand what you've written, but in order to make that code work you need to cast model to QStandardItemModel*.

What do you need the item for?

Thank you, working.

Code:

---

void Delegate::setModelData(QWidget * editor, QAbstractItemModel * model, const QModelIndex & index) const
{
 
    QStandardItemModel *sModel = qobject_cast<QStandardItemModel *>(model);
    QStandardItem *item = sModel->itemFromIndex(index.model()->index(0,0));
 
    QList<QStandardItem *> newRows;
    newRows.append( new QStandardItem("one") );
    newRows.append( new QStandardItem("two") );
 
    item->appendRows( newRows );
