关于Java中生成输入的Robot类用法总结

This class is used to generate native system input events for the purposes of test

automation, self-running demos, and other applications where control of the

mouse and keyboard is needed. The primary purpose of Robot is to facilitate

automated testing of Java platform implementations.

Using the class to generate input events differs from posting events to the AWT

event queue or AWT components in that the events are generated in the

platform's native input queue. For example,

Robot.mouseMove

will actually move

the mouse cursor instead of just generating mouse move events.

Note that some platforms require special privileges or extensions to access low-

level input control. If the current platform configuration does not allow input

control, an

AWTException

will be thrown when trying to construct Robot objects.

For example, X-Window systems will throw the exception if the XTEST 2.2

standard extension is not supported (or not enabled) by the X server.

Applications that use Robot for purposes other than self-testing should handle

these error conditions gracefully.

Constructor Summary

Robot()
Constructs a Robot object in the coordinate system of the primary screen.

Robot(GraphicsDevice screen)
Creates a Robot for the given screen device.

Method Summary

BufferedImage	createScreenCapture(Rectangle screenRect) Creates an image containing pixels read from the screen. （传说中的截屏，保存在BufferedImage里，如果了解过AWT里的画图对BufferedImage一定不陌生）
void	delay(int ms) Sleeps for the specified time.（和线程里面的睡眠效果一样，只不过现在对象变成了输入端的机器人）
int	getAutoDelay() Returns the number of milliseconds this Robot sleeps after generating an event.
Color	getPixelColor(int x,int y) Returns the color of a pixel at the given screen coordinates. （类似于画图里面的采色器）
boolean	isAutoWaitForIdle() Returns whether this Robot automatically invokes waitForIdle after generating an event.
void	keyPress(int keycode) Presses a given key.（产生一个类似于你按了一个键的效果）
void	keyRelease(int keycode) Releases a given key.（同上，只不过这回变成了释放）
void	mouseMove(int x,int y) Moves mouse pointer to given screen coordinates. (移动鼠标到指定位置)
void	mousePress(int buttons) Presses one or more mouse buttons. （鼠标按键按下的事件，参数是鼠标上的哪一个键，有左键右键和滑轮）
void	mouseRelease(int buttons) Releases one or more mouse buttons. （同上，不解释）
void	mouseWheel(int wheelAmt) Rotates the scroll wheel on wheel-equipped mice. （滚动滑轮，参数的正负代表向上还是向下，参数的值代表滑槽转了几下）
void	setAutoDelay(int ms) Sets the number of milliseconds this Robot sleeps after generating an event.
void	setAutoWaitForIdle(boolean isOn) Sets whether this Robot automatically invokes waitForIdle after generating an event.
String	toString() Returns a string representation of this Robot.
void	waitForIdle() Waits until all events currently on the event queue have been processed.
