1.5

Static Methods
	Modifier and Type	Static Method and Description
	getNumberOfButtons	`static int` getNumberOfButtons() Returns the number of buttons on the mouse. public static int getNumberOfButtons() throws HeadlessException Returns the number of buttons on the mouse. On systems without a mouse, returns `-1`. Returns: number of buttons on the mouse Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true Since: 1.5
	getPointerInfo	`static PointerInfo` getPointerInfo() Returns a `PointerInfo` instance that represents the current location of the mouse pointer. 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`. If there is a security manager, its `checkPermission` method is called with an `AWTPermission("watchMousePointer")` permission before creating and returning a `PointerInfo` object. This may result in a `SecurityException`. Returns: location of the mouse pointer Throws: `HeadlessException` - if GraphicsEnvironment.isHeadless() returns true `java.lang.SecurityException` - if a security manager exists and its `checkPermission` method doesn't allow the operation Since: 1.5 See Also: `GraphicsConfiguration`, `SecurityManager.checkPermission(java.security.Permission)`, `AWTPermission`
