How to get list of tracks in a Audio CD/VCD/DVD?

[Yogesh Marwaha]

I see in the Phonon documentation that
MediaSource (Phonon::DiscType discType, const QString &deviceName=QString())
can be used to play audio cd/VCD/DVD, but there seems no way to get a
list of tracks in the disc or any way to directly switch between the
tracks. How can this be done?

Regards,
