find item in QListView

I want to get the index of item of QListView and set at this item focus. The items are strings! How can I make it?

I have made this is:

Code:

---

void LicenceBuilder::findLeftSN(const QString& new_SN)
{
	if(new_SN.isEmpty()) return;
 
	QSqlTableModel model;
	model.setTable("DeviceList");
	model.select();
	QStringList listNames, selList;
	for(int i=0; i<model.rowCount(); ++i)
	{
		QSqlRecord record = model.record(i);
		listNames.append(record.value("serialNumber").toString());
	}
	foreach(QString name, listNames)
		if(name.indexOf(new_SN, 0, Qt::CaseInsensitive) != -1)
			selList.append(name);
 
          /// What to do??????
}

---

This slot must find index of item and set focus. Help me, please!

have you had a look at QAbstractItemModel::match()?

Thanks! I try :)

GREAT THANKS! It helped me. This code resolve this problem:

Code:

---

/// Поиск в левом списке номера, часть (или он весь) которого отражена в new_SN
void LicenceBuilder::findLeftSN(const QString& new_SN)
{
        // after phrase What to do??????
 
	QModelIndexList indexList = model.match(model.index(0, 0), Qt::DisplayRole, selList.first());
	QModelIndex selectedIndex(indexList.first());
	listDBNumbers -> setCurrentIndex(selectedIndex);
}
