Examples of prefuse.Display.rotate()

prefuse.Display.rotate()
Rotates the view provided by this display by the given angle in radians, anchoring the rotation at the specified point in screen coordinates. @param p the anchor point for the rotation, in screen coordinates @param theta the angle to rotate by, in radians

            double angle = Math.atan2(dy, dx);
            
            // only rotate once the base angle has been established
            if ( !Double.isNaN(baseAngle) ) {
                Display display = (Display)e.getComponent();
                display.rotate(down, angle-baseAngle);
            }
            baseAngle = angle;
        }
    }
