在PyQt的QThread调试中，关闭X窗口时，报了守护线程错误，怎么解决

这是报错

这是代码

import sys
from PyQt6 import QtWidgets
from PyQt6.QtCore import QThread
from PyQt6.QtCore import pyqtSignal
import PD  # PyUic生成的UI文件


class Windows(QtWidgets.QMainWindow, PD.Ui_MainWindow):

    def __init__(self):
        super(Windows, self).__init__()
        self.setupUi(self)
        self.add_text = AddText()
        # self.add_text.setDaemon(True)  # QThread没有setDaemon
        self.add_text.start()
        self.add_text.signal.connect(self.add_box)

    def add_box(self, text):
        pass


class AddText(QThread):

    signal = pyqtSignal(list)

    def __init__(self):
        """子线程，用于调试文本"""
        super(AddText, self).__init__()
        self.txt = list()

    def run(self):
        while True:
            self.input_txt()
            self.signal.emit(self.txt)

    def input_txt(self):
        try:
            val = input("请输入：")
            self.txt.append(val)
        except Exception as e:
            pass


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Windows()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec())

你把while true用try包住就可以捕捉错误了
你主线程退出了，守护线程肯定要抛错误啊，这是正常现象
