在Java Swing中监听屏幕上的任意位置

Question

我想创建一个Java应用程序，以便记录和重放鼠标正在做的事情。现在我有这个代码：

static JFrame j = new JFrame();
static JPanel p = new JPanel();
static JButton record = new JButton("RECORD");
static JButton replay = new JButton("REPLAY");
static JButton stop = new JButton("STOP");

public static boolean btnrec;
public static boolean btnrepl;
public static boolean btnstp = false;

public static boolean enRec = true;
public static boolean enRepl = false;
public static boolean enStp = false;

public static boolean clicked;

public static boolean rest = false;



static ArrayList<Point> pos = new ArrayList<>();
static ArrayList<Integer> time = new ArrayList<>();
static ArrayList<Boolean> leftClicked = new ArrayList<>();
static ArrayList<Boolean> rightClicked = new ArrayList<>();

static int timer;

static int keep;

static boolean mouseClicked;

static boolean rec = true;
static boolean repl;
static boolean stp;

public static void main(String[] args) {

    j.setTitle("Repeate Mouse");
    j.setAlwaysOnTop(true);
    j.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    j.setSize(350, 200);
    j.setResizable(false);
    j.setLocation(new Point(420, 420));
    j.setVisible(true);

    stop.setEnabled(enStp);

    record.setSize(175, 40);
    record.setEnabled(enRec);

    replay.setSize(175, 40);
    replay.setEnabled(enRepl);

    record.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            btnrec = true;
            btnrepl = false;
            replay.setEnabled(true);
            stop.setEnabled(false);
            record.setEnabled(false);
            j.setTitle("Recording...");
        }
    });

    replay.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            btnrepl = true;
            btnrec = false;
            replay.setEnabled(false);
            stop.setEnabled(true);
            record.setEnabled(false);
        }
    });
    stop.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            btnstp = true;
            btnrepl = false;
            replay.setEnabled(true);
            stop.setEnabled(false);
            record.setEnabled(true);
        }
    });

    p.add(record);
    p.add(replay);
    p.add(stop);
    j.add(p);
    j.addMouseListener(new MouseListener() {

        @Override
        public void mouseReleased(MouseEvent e) {
            clicked = false;

        }

        @Override
        public void mousePressed(MouseEvent e) {
            clicked = true;

        }

        @Override
        public void mouseExited(MouseEvent e) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mouseEntered(MouseEvent e) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mouseClicked(MouseEvent e) {
            // TODO Auto-generated method stub

        }
    });

    timer = -1;
    try {
        Thread.sleep(100);
    } catch (InterruptedException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
    while(j.isVisible()) {
        System.out.println("");
        if(btnstp) {
            stop();
        }
        if(btnrec) {
            record();
        }
        if(btnrepl) {
            replay();
        }

    }

}

protected static void record() {
    pos.add(new Point(MouseInfo.getPointerInfo().getLocation()));
    time.add(timer);
    leftClicked.add(clicked);
    timer++;
    System.out.println(pos.get(timer));
    System.out.print(leftClicked.get(timer));
    j.setTitle("Recording....");
}

protected static void replay() {
    if(!rest) {
        timer = 0;
        rest = true;
    }
    if(leftClicked.get(timer)) {
        try {
            MouseAPI.genLeft();
        } catch (Exception e) {}
    }
    try {
        MouseAPI.move(pos.get(timer));
    } catch (Exception e) {}
    if(timer != time.size()-1) {
        timer++;
    } 
    else {
        rest = false;
    }

}

protected static void stop() {

}

因此，您可以看到我将所有点和鼠标点击存储在ArrayList中。我的问题是，该程序仅记录在JFrame中发生的点击。 有没有办法监听在JFrame之外发生的点击？

非常感谢！
