Windows上的PyQt4应用程序在退出时崩溃 [英] PyQt4 application on Windows is crashing on exit

问题描述

我使用PyQt4编写了一个桌面应用程序，并且突然在退出时崩溃了。

I am writting a desktop application with PyQt4 and all of the sudden it started to crash on exit.

我检查了所有的代码，

I reviewed all of my code to make sure I wasn't doing anything funny to make it crash and I don't think there's anything wrong with the code.

我已经看到一些关于这个的投诉，但它是相关的一个以前的版本，人们建议升级到最新版本的PyQt4，所以我没有，但是没有帮助崩溃的问题。

I have seen some complaints about this before but it was related to a previous version and people advised to upgrade PyQt4 to the latest version and so I did, but that didn't help with the crashing problem.

所以我问，有什么这可以导致这种行为与PyQt4，我需要做一些终止过程清理Qt或任何我缺少的东西？

So I ask, is there anything that can lead to this behavior with PyQt4, do I need to do some kind on termination procedure to cleanup Qt or anything else I am missing?

推荐答案

我有一个简单的hello世界应用程序（QDialog与20标签）相同的问题。

I had the same problem with a simple hello world application (QDialog with 20 labels). Weirdly the problem disappears with 10 labels.

我通过强制退出解决如下：

I solved by forcing exit as follows:

def closeEvent(self, event):
    exit()

在Windows上使用PyQt v4.10.3 for VirtualBox上的Python v2.7（x32）。

This happens on Windows with PyQt v4.10.3 for Python v2.7 (x32) on VirtualBox.
