A QuickTime movie may contain several tracks. Each track refers to a media that contains references to the movie data, which may be stored as images or sound on hard disks, floppy disks, compact discs, or other devices. Specifies the track for an operation. Your application obtains a track identifier from such Movie Toolbox functions as NewMovieTrack and GetMovieTrack (described on page 2-151 of Inside Macintosh: QuickTime and page 2-204 of Inside Macintosh: QuickTime, respectively).<BR> You make a new Track object only through addTrack or getTrack methods on a movie object.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!--
