beginInsertRows doesn't appear to be working?

Does DATreeModel::setCanData() get called only once or many times? I think you might be looking for something like this:

void DATreeModel::setCanData( CANDATA *pData, int nAmount, int nCount )
{
    if( pData )
    {
        int row = rowCount();
        beginInsertRows(QModelIndex(), row, row + nAmount - 1);
        ...
        endInsertRows();
    }
}

void DATreeModel::setCanData( CANDATA *pData, int nAmount, int nCount )
{
    if( pData )
    {
        int row = rowCount();
        beginInsertRows(QModelIndex(), row, row + nAmount - 1);
        ...
        endInsertRows();
    }
}
