Access to Underpinnings

Once a movie control is created, you can access its associated movie, its underlying movie controller or change certain options using the GetControlData() and SetControlData() routines.

The following are the selectors that can be passed to these control manager functions:

kMovieControlDataMovieController

Use with GetControlData() to obtain the movie controller. This allows the application access to more features of QuickTime and finer control over aspects of movie playback and editing. IMPORTANT NOTE: Do not dispose of this movie controller; it is owned by the movie control it is associated with. You also must not use MCSetControllerAttached() to detach the controller from the movie.

kMovieControlDataMovie

A GetControlData() convenience to obtain the movie associated with a movie control after its creation.

kMovieControlDataManualIdling

Used with GetControlData() and SetConrolData() to obtain and modify the state of the movie control’s idling behavior. By default, all movie controls are given time by the movie control event loop timer. Setting this Boolean item to TRUE will allow the application to manually idle the movie using MCIdle().
