QAbstractTableModel data insert issues

[nategoofs]

Im trying to add elements to a QAbstractTableModel via the QVariant data function like so

QVariant WTrackTableModel :: data(const QModelIndex &index, int role) const
{
	TrackInfoObject *m_pTrackInfo = m_pTrackCollection->getTrack(index.row());
	QStringList trackInfoList;
	trackInfoList.append(m_pTrackInfo->getScoreStr());
	trackInfoList.append(m_pTrackInfo->getTitle());
	trackInfoList.append(m_pTrackInfo->getArtist());
	trackInfoList.append(m_pTrackInfo->getType());
	trackInfoList.append(m_pTrackInfo->getDurationStr());
	trackInfoList.append(m_pTrackInfo->getBitrateStr());
	trackInfoList.append(m_pTrackInfo->getBpmStr());
	trackInfoList.append(m_pTrackInfo->getComment());
 
	if (!index.isValid())
		return QVariant();
 
    if (index.row() >= m_pTrackCollection->getSize())
        return QVariant();
 
    if (role == Qt::DisplayRole)
        return trackInfoList;
    else
        return QVariant();
}

QVariant WTrackTableModel :: data(const QModelIndex &index, int role) const
{
	TrackInfoObject *m_pTrackInfo = m_pTrackCollection->getTrack(index.row());
	QStringList trackInfoList;
	trackInfoList.append(m_pTrackInfo->getScoreStr());
	trackInfoList.append(m_pTrackInfo->getTitle());
	trackInfoList.append(m_pTrackInfo->getArtist());
	trackInfoList.append(m_pTrackInfo->getType());
	trackInfoList.append(m_pTrackInfo->getDurationStr());
	trackInfoList.append(m_pTrackInfo->getBitrateStr());
	trackInfoList.append(m_pTrackInfo->getBpmStr());
	trackInfoList.append(m_pTrackInfo->getComment());

	if (!index.isValid())
		return QVariant();

    if (index.row() >= m_pTrackCollection->getSize())
        return QVariant();

    if (role == Qt::DisplayRole)
        return trackInfoList;
    else
        return QVariant();
}

This code causes my program to crash. What I'm aiming to do is place the trackinfoobject's various get functions QString information into their respective columns (score, title, artist, etc.) what do I need to change to do so?

Thanks!
