移动适配代码java java适配模式( 三 )

int flag;//flag=1代表Mouse Moved,flag=2代表Mouse Dragged
int x=0;
int y=0;
int startx,starty,endx,endy;//起始坐标与终点坐标
public MouseDemo3(){
Container contentPane=getContentPane();
contentPane.addMouseListener(this);
contentPane.addMouseMotionListener(this);
setSize(300,300);
show();
addWindowListener(
new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
}
);
}
/*由mousePressed(),mouseReleased()取得示拖曳的开始与结束坐标*/
public void mousePressed(MouseEvent e){

/*mouseMoved(),mouseDragged()取得鼠标移动的每一个坐标，并调用repaint()方法*/

例3
实现一个简单的鼠标控制程序MouseController 。程序功能很简单：随机移动鼠标并点击左键。
代码如下：
import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.event.InputEvent;
import java.util.Random;
/**
*
*/
/**
* @Create date 2007-11-6
*/
public class MouseController implements Runnable {
private Dimension dim;
private Random rand;
private Robot robot;
private volatile boolean stop = false;
public MouseController() {
dim = Toolkit.getDefaultToolkit().getScreenSize();
rand = new Random();
try {
robot = new Robot();
} catch (AWTException ex) {
ex.printStackTrace();
}
}
public void run() {
while(!stop) {
int x = rand.nextInt(dim.width);
int y = rand.nextInt(dim.height);
robot.mouseMove(x, y);
robot.mousePress(InputEvent.BUTTON1_MASK);
try {
Thread.sleep(2000);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
}
}
public synchronized void stop() {
stop = true;
}
public static void main(String[] args) {
MouseController mc = new MouseController();
Thre
$False$
ad mcThread = new Thread(mc);
System.out.println("Mouse Controller start");
mcThread.start();
try {
Thread.sleep(60000);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
mc.stop();
System.out.println("Mouse Controller stoped");
}
}
例4 本例程演示鼠标监听器，鼠标点击和运动的监听。
