程序说明：

本例采用API函数实现模拟的鼠标事件，程序运行后会

产生十分有趣的效果。也来试一试。

本例中只使用了相对鼠标坐标，我们也可以使用绝对

鼠标坐标来试一试。-procedures Note : In this example, using API functions simulation of a mouse, running will have a very interesting results. Also to test. In this example, use only the relative coordinates of the mouse, we can also use the absolute coordinates of the mouse to test.
