QTreeWidgetItem swap or move up one level problem

I have build a tool to manage xml tree categories on infinite level but now...
i like insert a function to move up item or swap item ...

My question... exist a similar function from QTreeWidgetItem to make this?
I can access each QTreeWidgetItem by nummer

Code:

---

void  Tree_Category::AppendItemTree() 
{
    if (Maus_Select_Active) {  /* active QTreeWidgetItem */
    /*int sotto_totale = Niagara_Actual->childCount();*/
    /*niagara->editItem(Niagara_Actual,0);*/
    /*qDebug() << "### found 0   " << sotto_totale;*/
         bool ok;
         QString SetNewName = QInputDialog::getText(this, tr("New Item append here"),tr("Name:"), QLineEdit::Normal,"", &ok);
          if (ok && !SetNewName.isEmpty()) { 
             QTreeWidgetItem *newsub = new QTreeWidgetItem(Niagara_Actual); 
                 watposition++;   /* numeration */
                 QString xput = QString("[%1] %2").arg(QString::number(watposition),SetNewName);
                 newsub->setText(0,xput);
                 newsub->setToolTip(0,xput);
                 PutOptionNow(newsub);   /* set various option and put to other class qlist */ 
          }
    } else {
       QMessageBox::warning( this, tr( "Error" ), tr( "Select on item please!")); 
    }
}

QTreeWidget doesn't provide such functionality out of the box. This thread contains code example for swapping 2 rows in a QTableWidget. It should be rather straigthforward to adjust for QTreeWidget.

i found a solution .....

by loading QTreeWidget and update load all text to a QStringList ....
by move or swap select destination from a combobox QStringList

search the destination text findname .....

Code:

---

QList<QTreeWidgetItem*> items = niagara->findItems(findname, Qt::MatchRecursive | Qt::MatchExactly , 0);
 
if (items.count() == 1) {
    /* clone source and destination and update source to "findname" ....*/
 }

---

so i can swap item to all level :-) .....
