               throws <A HREF="../../../quicktime/QTException.html">QTException</A></PRE>
<DL>
<DD>QTCanvas calls this method to give the client the QDGraphics object it should 
 use to do its drawing. If the incoming QDGraphics is the QDGraphics.scratch then
 the drawable will not be visible and can disable itself.
 If a client is unable to set the graphics world it should throw an exception.

execute</H3>
<PRE>
public int <B>execute</B>(<A HREF="../../../quicktime/std/movies/Movie.html">Movie</A>&nbsp;m)</PRE>
<DL>
<DD>Implements the execute method on the MovieDrawingComplete interface.
 This method will set the movie changed state to true, so that a consequent
 call to the TwoDSprite Invalidator will invalidate its presenting sprite.
 If the MoviePresenter is presenting a movie to a destination QDGraphics
 it will redraw the movie to that destination. 
 <P>
 The callback will be triggered as a result of a call to Movie.task and 
 is fired whenever the Movie draws to its internal QDGraphics - the offscreen buffer
 that the presenter presents.<DD><DL>

<DL>
<DD>QTCanvas calls this method when the client should redraw itself.
 If the canvas is able to discern that only a part of the client's 
 drawing area needs to be redrawn - then this area shall be passed in
 using the invalidRgn. Otherwise this will be null in which case the
 client should redraw itself entirely.<DD><DL>
