I guess they are.

This is the function which gets called after the thread has changed the data ( m_can[i] ), the thread emits scrolltable function which ends up calling the code below:

Qt Code: 
  1. void DATreeModel::setCanData( int nAmount, int nCount )
  2. {
  3. 	int row = rowCount();	
  4.  
  5. 	beginInsertRows(QModelIndex(), row, row + nAmount - 1 );  // insert nAmount of rows
  6.  
  7. 	QMutex mutex;
  8. 	mutex.lock();
  9.  
  10. 	for( int i = 0; i < nAmount; i++ )
  11. 	{
  12. 		m_Data.append(m_can[i].strId);
  13. 		m_Data.append(m_can[i].strTime);
  14. 		m_Data.append(m_can[i].strData);
  15. 		QString strCount;
  16. 		strCount.sprintf( "%i", nCount );	
  17. 		m_Data.append(strCount);
  18. 		nCount++;
  19.  
  20. 	}
  21. 	mutex.unlock();
  22.  
  23. 	endInsertRows();
  24. }
