線程定時器.cancel

Question

我不過運行函數中的每條60秒，打印字符串文本框

def devPresent(self): 
    stdout = self.deviceExists() 
    exists = self.exactMatch(stdout, "device") 
    if "device" in str(exists): 
     self.progressBox.AppendText('TEST STILL HERE\n') 
    else: 
     self.progressBox.AppendText('Device connection lost\n') 
     self.rstBtn() 
    t = threading.Timer(60, self.devPresent) 
    t.start() 

所以此工程和測試仍然在這裏被打印到progressBox，一個線程計時器當我用下面的def關閉窗口時，它會關閉主窗口，但另一個窗口會彈出並凍結。

def closeWindow(self,e): 
    t = self.devPresent 
    t.cancel() 
    time.sleep(3) 
    self.Destroy() 

我錯誤地關閉了線程嗎？

Answer 1

t在類方法之間將不可見，除非將其設置爲self的屬性。嘗試：

def devPresent(self): 
    stdout = self.deviceExists() 
    exists = self.exactMatch(stdout, "device") 
    if "device" in str(exists): 
     self.progressBox.AppendText('TEST STILL HERE\n') 
    else: 
     self.progressBox.AppendText('Device connection lost\n') 
     self.rstBtn() 
    self.t = threading.Timer(60, self.devPresent) 
    self.t.start() 


def closeWindow(self,e): 
    self.t.cancel() 
    time.sleep(3) 
    self.Destroy()
