Call-backs provide the facility for QuickTime to invoke your Java application code, at specific points, during program execution. Call-backs are provided in many parts of QuickTime including the MovieController, Movie and QuickTimeVR APIs.

The user to chooses a movie using the standard open file dialogue, that also shows a preview. Afterwards, a number of call-backs are installed. Depending on the type of movie opened, different callbacks are installed:

(1) Movie - DrawingComplete proc is used to notify the Java program whenever QuickTime draws to the screen.

(2) MovieController - ActionFilter procs are used - this subclass overides those actions that pass no parameters or a float parameter.

(3) If the Movie contains QuickTime VR content then a number of QTVR callbacks are installed and invoked when panning, tilting, hot-spot entering and leaving.
