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_SystemListViewModel->setRootPath(sPath);
ui->DriveListView->setRootIndex(m_SystemListViewModel->index(sPath));m_SystemModel->setRootPath(QDir::currentPath());
m_SystemModel->setFilter(QDir::NoDotAndDotDot | QDir::AllDirs );
m_SystemListViewModel->setFilter( QDir::Files | QDir::NoDotAndDotDot );QDirIterator dirIt(sPath,QDirIterator::Subdirectories);
while (dirIt.hasNext())
{
dirIt.next();
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); ui->DriveListView->setModel(model); m_count++; } } m_SystemListViewModel->setNameFilterDisables(false);
}
}@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.
