The TaskAllMovies call then has a single thread and taskable object (itself) that calls the Moive.taskAll to let QuickTime's MovieTask call do the required tasks for any of these active Movies and TimeBases. <P> An application can retrieve the Tasking object and set its default thread to a TaskThread object of its choice.<P><DL><DT><B>See Also: </B><DD><A
