    • getPointerInfo

      public static PointerInfo getPointerInfo() throws HeadlessException
      Returns a PointerInfo instance that represents the current location of the mouse pointer. The GraphicsDevice stored in this PointerInfo contains the mouse pointer. The coordinate system used for the mouse position depends on whether or not the GraphicsDevice is part of a virtual screen device. For virtual screen devices, the coordinates are given in the virtual coordinate system, otherwise they are returned in the coordinate system of the GraphicsDevice. See GraphicsConfiguration for more information about the virtual screen devices. On systems without a mouse, returns null.
      Returns:
      location of the mouse pointer
      Throws:
      HeadlessException - if GraphicsEnvironment.isHeadless() returns true

    • getNumberOfButtons

      public static int getNumberOfButtons() throws HeadlessException
      Returns the number of buttons on the mouse. On systems without a mouse, returns -1. The number of buttons is obtained from the AWT Toolkit by requesting the "awt.mouse.numButtons" desktop property which is set by the underlying native platform.
      Returns:
      number of buttons on the mouse
      Throws:
      HeadlessException - if GraphicsEnvironment.isHeadless() returns true
