PyQt这样写为什么前几天还能跑，过几天就不行了，，，

self.loginBtn = QPushButton("登录")
self.loginBtn.setObjectName("loginBtn")
self.loginBtn.clicked.connect(self.loginFunc)


def loginFunc(self):
        if self.passwordBox.text() == "" or self.accountBox.text() == "":
            self.otherLabel.setText("""<font style="color:red">账号密码不能为空</font>""")
            return
        self.childWorker = worker(account = self.accountBox.text(),password = self.passwordBox.text(),x=self.x()+350,y=self.y()+150)
        self.childWorker.login.connect(self.callback)
        self.childWorker.start()


class worker(QThread):

    login = pyqtSignal(str)
    # scanover = pyqtSignal(str)
    def __init__(self,parent=None,account=None,password=None,x=0,y=0):
        super(worker,self).__init__(parent)
        self.account = account
        self.password = password
        self.x = x
        self.y = y
    def __del__(self):
        self.wait()
    def run(self):
        self.login.emit("""<font style="color:#0f0">正在进行内部操作，请等待...</font>""")
        app.processEvents()
        ...
        self.eventloop = QEventLoop()
        self.qrlabel = QLabel()
        self.qrlabel.show()
        .....
        self.childWorker2 = worker2(qrlabel = self.qrlabel)
        self.childWorker2.scan.connect(self.isLoginSuccess)
        self.childWorker2.start()
        self.childWorker2.quitevent.connect(self.loop)
        self.eventloop.exec_()


class worker2(QThread):
    scan = pyqtSignal(str)
    quitevent = pyqtSignal(str)
    def __init__(self,parent=None,qrlabel=None):
        super(worker2,self).__init__(parent)
        self.qrlabel = qrlabel
    def __del__(self):
        self.wait()
    def run(self):
        app.processEvents()
        while True:
            ....
            self.quitevent.emit("loop可以退出了")
