highlight a selected row in a QTreeView without clicking on it

Hi to all,
I'm using a QTreeView to list items, I hide the QTreeView after a row selection and then show it setting correctly the current index but I don't know how to highlight the row. The following it has been my attempt (rows 18-19):

Code:

---

void frmTitoli::funModifica()
{
   QModelIndexList selection = ui.tvView->selectionModel()->selectedRows(0);
 
   if (!selection.empty())
   {
      QModelIndex idIndex = selection.at(0);
      int id = idIndex.data().toInt();
 
      ui.tvView->hide();
 
      ...
 
      ui.tvView->show();
 
      refreshView();
 
      ui.tvView->setFocus();
      ui.tvView->selectionModel()->setCurrentIndex(idIndex, QItemSelectionModel::SelectCurrent);
   }
   else
   {
      QMessageBox::warning(this, tr("Attenzione!"),
         tr("Selezionare prima un elemento nella lista!"),
         QMessageBox::Ok);
   }
}

Thanks!!!

Have you seen QItemSelectionModel::select()?

You can access the selection model with QAbstractItemView::selectionModel()

Yes, I've tried:

Code:

---

void frmTitoli::funModifica()
{
   QModelIndexList selection = ui.tvView->selectionModel()->selectedRows(0);
   QItemSelection rowSel = ui.tvView->selectionModel()->selection();
 
   if (!selection.empty())
   {
      QModelIndex idIndex = selection.at(0);
      int id = idIndex.data().toInt();
 
      ui.tvView->hide();
 
...
 
      ui.tvView->show();
 
      refreshView();
 
      ui.tvView->setFocus();
      ui.tvView->selectionModel()->setCurrentIndex(idIndex, QItemSelectionModel::SelectCurrent);
      ui.tvView->selectionModel()->select(rowSel, QItemSelectionModel::SelectCurrent);
   }
   else
   {
      QMessageBox::warning(this, tr("Attenzione!"),
         tr("Selezionare prima un elemento nella lista!"),
         QMessageBox::Ok);
   }
}

Did you ever get this working?

How did you do it?

Thanks.
