扭曲的Tkinter

Question

我一直在尝试Twisted和Tkinter。我有一个小程序正在工作，我可以单击Tkinter中的按钮，它将向本地服务器发送请求。这是通过调用MessageCFactory来完成的。这工作正常，但是当服务器返回其响应时，我的“已接收数据”方法无法捕获它。这可能是由于我不了解反应堆回路。

希望有人能指出我正确的方向

谢谢！

    root.title('GUI')
    root.geometry('{}x{}'.format(460, 350))

    middleFrame = Frame(root)
    middleFrame.pack()
