关闭窗口时出现Python PyDeadObjectError

这是我的代码（不全是f，因为太长了）

[……]

下面是错误消息

    Exception in thread Thread-1:

每次我尝试关闭它时都会发生这种情况。完全相同的代码在TKinter上运行得非常好，但由于某些原因，我无法用WX克服它。有什么想法吗？

看起来您是因为线程中出现错误而退出应用程序的。您应该向wxpythongui发送一条消息，告诉它有问题。您可以向用户显示错误消息，也可以在此时退出脚本。除非使用线程安全方法，例如wx.CallAfter或wx.PostEvent，否则无法从GUI调用wxPython中的任何内容

我将使用其中一个来告诉您的GUI它需要退出。我编写了一个小教程，展示了如何在线程中使用wxPython，您可以在这里查看：

很抱歉，我仍然不清楚为什么以及在哪里使用wx.CallAfter。我的意思是，在出现错误时我没有使用GUI，它只是背景代码。其次，如果我将

self.disconnect（）

更改为

wx.CallAfter（self.disconnect）

我仍然会得到相同的错误。最后，

try，除了

不会捕获它。更新：如果我更改

if msg==“SPECIAL\u msg\u disconnected\u 70”：self.disconnect（）

与：

if msg==“SPECIAL\u msg\u disconnected\u 70”和self.is\u connected\u flag1==True:self.disconnect（）

我得到相同的错误，但对于if行。。。
