Notes & Comments

The code displays a frame with two AWT buttons in a JAVA Frame. The Play Midi button
would play midi media file upon clicking and the Play Sound button would stop the current
midi file if its playing and play a sound file. This could be used to even play sound using
http, rtsp... files over the net.

General Comments

- QTSession.open and close:

A QTSession.open will perform a gestalt check to ensure that QuickTime is present and is initialized. This is a required call before any QuickTime Java classes can be used.

When the user closes the window the program will quit, first calling QTSession.close to terminate QuickTime. It is necessary for programs to call QTSession.close if they have previously called QTSession.open in order to shut down QuickTime properly.
