Upon completion of the transition the source and destination images are swapped, so you can also transition back to the original source image or set a new desintation image. <P> The QTTransition can run in two modes - in time mode the doTransition method will run the effect in as close as time as possible to the time specified. In frames mode the effect will be run for the number of frames that are specified. <P> The doTransition method is provided as a means of running the transition according to the time or frames setting. The transition will run as effectively as possible from start to finish - it is a call that blocks the thread of execution that made this call whilst the transition is running. <P> If a transition should be run with more application control then the application can control the setting of the current frame of the transition and call redraw after setting each frame. The redraw method will redraw the current frame of the transition.<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A
