WindowIconfield and FocusLost don't work together

Question

I need to set mouse at specific place when JFrame loses focus, but not when minimized. I use Robot to set mouse on position when frame loses focus (FocusListener) by starting timer which calls robot to move mouse. And when WindowListener sees that frame is minimized it stops timer (because it will not call robot anymore). All works fine except that robot is still working even when minimized. By gaining focus, robot stops and all goes fine, but not when minimized.

Here is a code example. Can anyone help me?

public class Test extends JFrame {

Clipboard clipboard;
Robot robot;
Timer tmr;

private static final long serialVersionUID = 1L;

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
    public void run() {
        try {
            Test frame = new Test();
            frame.setVisible(true);
            frame.timer();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
});
}
void timer(){
ActionListener actionListener = new ActionListener() {
    public void actionPerformed(ActionEvent actionEvent) {
        System.out.println("Test");
        StringSelection selection = new StringSelection("");
        clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
        clipboard.setContents(selection, selection);
    }
};
Timer tmr = new Timer(500, actionListener);
tmr.start();
}

public Test() throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException {


addWindowListener(new WindowAdapter() {
    @Override
    public void windowIconified(WindowEvent arg0) {
        robot=null;
        tmr.stop();
    }
});
addFocusListener(new FocusAdapter() {
    @Override
    public void focusLost(FocusEvent arg0) {
        try {
            robot=new Robot();
        } catch (AWTException e) {
            e.printStackTrace();
        }
        ActionListener actionListener = new ActionListener() {
            public void actionPerformed(ActionEvent actionEvent) {
                robot.mouseMove(200, 200);
            }
        };
        tmr = new Timer(500, actionListener);
        tmr.start();
    }
    @Override
    public void focusGained(FocusEvent arg0) {
        robot=null;
        tmr.stop();
    }
});
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setBounds(100, 100, 431, 286);
getContentPane().setLayout(null);

}
}

FocusGained (which works fine) and windowIconfied (which doesn't works fine) have same event handles, but don't work same...

EDIT:

    tmr.start();

            }
            @Override
            public void windowActivated(WindowEvent arg0) {
                tmr.stop();
            }

            @Override
            public void windowClosing(WindowEvent arg0) {
                robot = null;
                tmr.stop();
            }

        });
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

setBounds(100, 100, 431, 286);
getContentPane().setLayout(null);

}

}

I just realized that when I minimize window using button it starts timer, and when minimize it by clicking on the taskbar program icon it stops fine. What is happening?

SOLVED:

I just added WindowStateListener and created field int state. When state changes I get it in field state. When Window deactivated, I ask if state is ICONFIED and then give instructions. Extremely simple but I tortured whit is all day.

Answer 1

You don't need to add FocusListener whereas you can achieve it by overriding other methods of WindowListener where you can start the timer when window is opened/activated/Deiconified and stop the time when window is closing/closed/Iconified.

Sample code:

public TestWidnowMinimize() throws ClassNotFoundException, InstantiationException,
        IllegalAccessException, UnsupportedLookAndFeelException {

    addWindowListener(new WindowAdapter() {

        @Override
        public void windowOpened(WindowEvent arg0) {
            try {
                robot = new Robot();
            } catch (AWTException e) {
                e.printStackTrace();
            }
            ActionListener actionListener = new ActionListener() {
                public void actionPerformed(ActionEvent actionEvent) {
                    System.out.println("Robot");
                }
            };
            tmr = new Timer(500, actionListener);
            tmr.start();
        }

        @Override
        public void windowIconified(WindowEvent arg0) {
            tmr.stop();
        }

        @Override
        public void windowDeiconified(WindowEvent arg0) {
            tmr.start();
        }

        @Override
        public void windowDeactivated(WindowEvent arg0) {
            tmr.stop();
        }

        @Override
        public void windowClosing(WindowEvent arg0) {
            robot = null;
            tmr.stop();
        }

    });
