Display Audio File Attributes in QTreeView

  • Well I need to display details of all .mp3 files present in my system drives. I am using QTreeView which gives me File Name, Size, Type and Date Modified by default to display. Here is the sample code:
    @void DetailView::on_DriveView_clicked(const QModelIndex &index)
    int m_count=0;
    QStringList m_list;
    QStandardItemModel *model = new QStandardItemModel(0,0);
    QString sPath = m_SystemModel->fileInfo(index).absoluteFilePath();

    m_SystemModel->setFilter(QDir::NoDotAndDotDot | QDir::AllDirs );
    m_SystemListViewModel->setFilter( QDir::Files | QDir::NoDotAndDotDot );

    QDirIterator dirIt(sPath,QDirIterator::Subdirectories);

    while (dirIt.hasNext())
    if (QFileInfo(dirIt.filePath()).isFile())
    if (QFileInfo(dirIt.filePath()).suffix() == "mp3")
    m_list << dirIt.filePath();

               QModelIndex index = model->index(m_count, 0, QModelIndex());
               model->setHeaderData( 0, Qt::Horizontal, "File Name" );
               model->setHeaderData( 1, Qt::Horizontal, "Size" );
               model->setHeaderData( 2, Qt::Horizontal, "Type" );
               model->setHeaderData( 3, Qt::Horizontal, "Date Modified" );
               model->setData( index, dirIt.fileName(), Qt::DecorationRole );
               QStandardItem *item = new QStandardItem(dirIt.fileName());
               model->setItem(m_count, item);


    When I run the app, Have a look at my code, even though I have used setHeaderData for Size, Type and Date Modified, it gets displayed when I run the application but the moment i click any system drive, only File Name appears and rest doesn't get displayed. I am using QTreeView, as of now my code displays all the .mp3 files under Name category. I want to display the Size, Date Modified, Type etc details too.
