signal rowsInserted in QAbstractTableModel

[Mihaill]

Hi!
I use Qt 5.15.
I use QAbstractTableModel and i want set table aboute added row.
I think that me need signam rowsInserted.
https://doc.qt.io/qt-5/qabstractitemmodel.html#rowsInserted
In documentatin that signal have 3 arguments, but QtCreater think that need 4 arguments, last argument - QPrivateSignal.
Whot me need doing?

@Mihaill
As per the docs you cited, your code cannot emit rowsInserted(). This is a signal Qt emits. Your job is to implement insertRows() and call beginInsertRows(). Read https://doc.qt.io/qt-5/qabstractitemmodel.html#subclassing carefully.

If you want to connect() to it that should be as per void QAbstractItemModel::rowsInserted(const QModelIndex &parent, int first, int last). The QPrivateSignal one you showed is not for you.

@JonB but how I can set TableView that in model apeared new row?

@Mihaill I guess: "Your job is to implement insertRows() and call beginInsertRows(). Read https://doc.qt.io/qt-5/qabstractitemmodel.html#subclassing carefully." ?

@jsulm I directly wrote a row to the data container, made beginInsertRows and endInsertRows, but the table is not updated.

I try use this, but it's not work:

            int row = m_data.count();
            QModelIndex index = createIndex(row, 0);
            beginInsertRows(index, row, row);
            addData(AlarmObject (item, isAlarm, QDateTime::currentDateTime(),
                                 m_client->getAlarmColorCategory(uuid)));
            endInsertRows();

it's work

            int row = m_data.count();
//            if (m_data.count() == 0) {
//                row = 0;
//            }
            QModelIndex index = createIndex(row, 0);
//            beginInsertRows(index, row, row);
            beginInsertRows(QModelIndex(), row, row);
            addData(AlarmObject (item, isAlarm, QDateTime::currentDateTime(),
                                 m_client->getAlarmColorCategory(uuid)));
            endInsertRows();
