This essentially does any initialisation that QT requires. <P> QTSession.open will intialize QuickTime, do a gestalt check and call enterMovies. Calls to the initialize routine are accumulative - thus if your code calls QTSession.open (which calls QTSession.initialize) and/or QTSession.initialize, the current session of QuickTime will only be closed down when it gets the same number of calls to QTSession.close (which calls QTSession.terminate) and/or QTSession.terminate. <P> A typical usage of QTSession calls by an application, applet or bean is: (this gives the applet version)<PRE>public class MyApplet extends Applet {public void init () {try {QTSession.open();...} catch (QTException e) {}}public void destroy () {QTSession.close();}}</pre> Thus the applet initializes the QTSession in its init method and closes it down in its destroy method. This ensures that if you have other applets (or beans, etc) that are running in the same process that the QuickTime session will only be terminated when all of the current Java QTSessions in that process have been destroyed.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3"
