Therefore, all classes which want to interact with a QTCanvas object, referred to as 'clients' must implement this interface.<p> The class that implements this interface must draw into the QDGraphics that is presented to the client - therefore this is not an appropriate interface for objects that are not QuickTime based drawing objects.<P> <em>Note: A Java applet or application never directly calls any of these Drawable methods -- the QTCanvas object associated with this Drawable object will call these methods as needed.</em><P> QTExceptions can be thrown by any of these methods and would indicate that either the graphics environment has changed in some unexpected way or that the media object itself is in some unexpected state.<P><HR><P><!-- ======== INNER CLASS SUMMARY ========
