Display Audio & Video Files In TreeView on Clicking Any Drive (QFileSystemModel)

[Stoned Jesus]

I want to traverse the drives present in my system and search for audio/video files inside it. Basically traverse the sub directories and display the file inside the treeview. I have 2 tree views, One to display System Directories and other to display audio/video files.

@// Displays System Drives inside TreeView When Application Starts
void PanasonicViewer::onCamStartup()
{
m_SystemModel = new QFileSystemModel(this);
m_SystemListViewModel = new QFileSystemModel(this);
m_SystemModel->setRootPath(QDir::currentPath());
ui->DriveView->setModel(m_SystemModel); //Left side TreeView
ui->DriveListView->setModel(m_SystemListViewModel); //Right Side TreeView

// regard less how many columns you can do this using for:
for(int nCount = 1; nCount < m_SystemModel->columnCount(); nCount++)
   ui->DriveView->hideColumn(nCount);

}

//On Clicking The TreeView, it should display Audio and Video files in my another tree view (DriveListView)
void PanasonicViewer::on_DriveView_clicked(const QModelIndex &index)
{
QStringList sDriveFilters;

QString sPath = m_SystemModel->fileInfo(index).absoluteFilePath();
ui->DriveListView->setRootIndex(m_SystemListViewModel->setRootPath(sPath));    

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

sDriveFilters << "*.aac" << "*.wmv" << "*.avi" << "*.mpeg" << "*.mov" << "*.3gp" << "*.flv" << "*.mp3" ;

m_SystemListViewModel->setNameFilters(sDriveFilters);
m_SystemListViewModel->setNameFilterDisables(false);

}@

You can notice in the above click event that I have set Filter to selected extensions. This seems to work and displays audio and video files when I click a drive i.e. E:\ but doesnt display the files present inside subfolders. Where am i going wrong?
