PyQt5中如何在关闭程序后保存Dial句柄的位置？

在这段代码中，我已经掌握了在按下“”按钮时将值保存checkBox在.iniВыход文件中。

代码中需要添加什么来保存调节器的位置Dial？

主文件

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.Qt import QSettings
from PyQt5.uic import loadUi

CONFIG_FILE_NAME = 'config.ini'


class New(QMainWindow):
    def __init__(self):
        super(New, self).__init__()

        loadUi("checkBox_Dial_save.ui", self)
        self.load_settings()
        self.Exit.clicked.connect(self.ExitClicked)

        self.dial.setMinimum(0)
        self.dial.setMaximum(10)
        self.dial.setValue(5)

    def save_settings(self):
        settings = QSettings(CONFIG_FILE_NAME, QSettings.IniFormat)
        settings.setValue('BoolValue', int(self.cb_flag.isChecked()))

    def load_settings(self):
        settings = QSettings(CONFIG_FILE_NAME, QSettings.IniFormat)
        self.cb_flag.setChecked(bool(int(settings.value('BoolValue', 0))))

    def ExitClicked(self):
        self.save_settings()
        sys.exit()


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = New()
    window.show()
    sys.exit(app.exec_())
