I answered my own question:

QVariant MyQFileSystemModel::data( const QModelIndex& index, int role ) const {
    if( role == Qt::DecorationRole )
    {
        QFileInfo info = MyQFileSystemModel::fileInfo(index);

        if(info.isFile())
        {
            if(info.suffix() == "dat")
                return QPixmap(":/icons/File_Icon.png");//I pick the icon depending on the extension
            else if(info.suffix() == "mcr")
                return QPixmap(":/icons/Region_Icon.png");
        }
    }
    return QFileSystemModel::data(index, role);
}
