Hi!
How in QAbstractItemModel emit signal about rowCountChanged?
Or how in QML TableView update rowCount?

How in QAbstractItemModel emit signal about rowCountChanged?

The row count changes when you either insert or remove a row (or reset/clear model). Signals come from the begin/endInsert/RemoveRows() implementations.

rowsInserted/Removed() signals --- see e.g. https://forum.qt.io/topic/48950/solved-qtablewidget-signal-for-rowcountchanged-needed/2.

@JonB Thanks
It's work:

void IndicationsModel::addUuid(const QUuid &uuid)
{
    m_uuidsSensors.append(uuid);
    beginInsertRows(QModelIndex(), m_uuidsSensors.count() - 1, m_uuidsSensors.count() - 1);
    insertRow(m_uuidsSensors.count() - 1);
    endInsertRows();
}
