performs the action of moving the Dragger's target (a Transformable object) according to the drag movements of the mouse. <P> Dragger's can be constrained to keep their target object completely within their enclosing space, or allow the target to be dragged out of that space to a default minimum view of 1 row or column of pixels of the target. <P> When a constraining condition is reached the Dragger will invoke the trigger method of an attached Actionable object. <P> NOTE: This class is no longer used and has been replaced by the new event model When converting your code, use a DragAction object in quicktime.app.event <P> <B>Example:</B> <P> <PRE>Dragger dragger = new Dragger (MouseResponder.kAnyModifiersMask); GroupController controller1 = new GroupController (dragger, true); drawer.addController (controller1);</PRE> <B>This code is replaced with:</B> <PRE>QTMouseTargetController qtmc = new QTMouseTargetController(true); qtmc.addQTMouseListener(new DragAction (new
