Examples of java.awt.PointerInfo

java.awt.PointerInfo
A class that describes the pointer position. It provides the GraphicsDevice where the pointer is and the Point that represents the coordinates of the pointer.
Instances of this class should be obtained via {@link MouseInfo#getPointerInfo}. The PointerInfo instance is not updated dynamically as the mouse moves. To get the updated location, you must call {@link MouseInfo#getPointerInfo} again. @see MouseInfo#getPointerInfo @version 1.3, 11/17/05 @author Roman Poborchiy @since 1.5

                    xOffset = -x1;

            final PointerInfo pi = MouseInfo.getPointerInfo();
            if (pi != null) {
                final Point2D p = pi.getLocation();
                robot.mouseMove((int) p.getX() + xOffset - 1,
