OSErr QTVRSetMouseOverTracking (QTVRInstance qtvr, Booleanenable);

An instance of a QuickTime VR movie.

DESCRIPTION

The QTVRSetMouseOverTracking function sets the mouse-over tracking state of the QuickTime VR movie specified by the qtvr parameter to the state specified by the enable parameter. By default, QuickTime VR tracks mouse movements in a QuickTime VR movie and changes the shape of the cursor as appropriate. If you disable mouse-over tracking (by passing false in the enable parameter), you must call the QTVRMouseEnter , QTVRMouseWithin , and QTVRMouseLeave functions at the appropriate times to handle user actions.
