### getScreenY

    public int getScreenY()

  Returns the vertical y position of the event relative to the screen.

  Returns:
    y a float indicating vertical position relative to the screen

### getScreenPoint

    public java.awt.Point getScreenPoint()

  Returns the (x, y) position of the event relative to the screen.

  Returns:
    a Point object containing the x and y coordinates

### getClientPoint

    public java.awt.Point getClientPoint()
