theParameters.setAutoScrollPolicy(
                    AutoScrollPolicy.WITHIN_FRAME);

theParameters.setAutoScrollPolicy(
                     AutoScrollPolicy.NONE);
If needed, set the autoscroll margin. 
theParameters.setAutoScrollMargin(250)
If needed, set the autoscroll delay. 
theParameters.setAutoScrollDelay(250)
If needed, set the autoscroll rate. 
theParameters.setAutoScrollRate(100)
Pass the initializer to the facade on creation. 
_facade = new AWTFacade(getParameters());
