beginInsertRows() rows expects the model index corresponding to the
parent of the new rows. Since you have a table model (which does not
have a valid parent), shouldn't you be passing an invalid model index
to beginInsertRows()?

Something like:

if ( inlist < m_maxNrMessages) {
    beginInsertRows(QModelIndex(), inlist+1, inlist+1);
}

You can use topLeft index while emitting the dataChanged() signal, though.
