wxPython GUI启动TCP服务器时丢失响应

最近，我在学习wxPython。所以我用wxPython写了一个小的TCP服务器程序。按下'init'按钮后，我的程序将崩溃。我还写了另一个客户端程序，它在服务器GUI失去响应时成功连接到这个wxPython TCP服务器。这真让我困惑。wxPython GUI启动TCP服务器时丢失响应

通常情况下，你只需要导入其他模块和实例化类。这样的事情会更好

import myFrame 

# then in your OnInit 
def OnInit(self): 
    frame = myFrame.Frame1()

或类似的东西。就个人而言，除非我打算做一些PreCreate的东西，否则我几乎从不子类wx.App。至于为什么你的GUI变得没有反应，你正在做一个长时间运行的过程，你的方法是阻止GUI的主循环。你会想要把你的套接字连接和通信代码放到一个单独的线程中，并使用wxPython的线程安全方法将结果传回。请参阅以下链接，了解更多信息：
