如果您关闭Pyqt5，它不会仅关闭窗口

Question

i使程序显示消息并在一段时间后更改消息，但是如果您关闭程序，它不会仅关闭窗口，请帮助如何关闭所有代码

此代码：

from PyQt5.QtWidgets import *
from PyQt5 import QtCore,QtGui
from threading import Timer
class s:
    def UI(self, window):
        window.setFixedHeight(500)
        window.setFixedWidth(600)
        self.Label = QLabel(window)
        self.Label.setGeometry(0, 0, 600, 500)
        self.Label.setAlignment(QtCore.Qt.AlignCenter)
        self.Label.setStyleSheet('font-size:100px')
        def mone():
            self.Label.setText('Hello')
            Tim = Timer(3, mtwo)
            Tim.start()
        def mtwo():
            Tim = Timer(3, mthree)
            self.Label.setText('World')
            Tim.start()
        def mthree():
            Tim = Timer(1, mfour)
            self.Label.setText('To')
            Tim.start()
        def mfour():
            Tim = Timer(1.5, mfive)
            self.Label.setText('My')
            Tim.start()
        def mfive():
            Tim = Timer(10, mone)
            self.Label.setText('Program')
            Tim.start()

        mone()
    def pd(self):
        print('d')
if __name__ == '__main__':
    import sys
    app = QApplication(sys.argv)
    form = QMainWindow()
    sd = s()
    sd.UI(form)
    form.show()
    sys.exit(app.exec_())

您可以尝试使用QtCore.QTimer代替threading.Timer，例如（请注意，QTimer中的时间间隔以毫秒为单位）
