之前没有这样做过,所以显然我很沮丧.这里,当前鼠标位置周围的64个像素在表单上绘制得更大.问题是,它有点'缓慢',我不知道从哪里开始修复.

        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent we) {
                t.done();
                dispose();
            }
        });
        try {
            robot = new Robot();
        } catch (AWTException e) {
            e.printStackTrace();
