我正在运行 PyQt5 制作的游戏库中的 pygame 蛇游戏。我正在使用 QThread 运行。在我关闭游戏之前它一直运行良好。每当我使用关闭按钮关闭游戏时，pygame 窗口和 GUI 都会停止响应。我该如何解决这个问题：

不要混合框架。这些框架可能彼此交互不良或完全冲突。如果它适用于您的（操作系统）系统，并不意味着它也适用于另一个（操作系统）系统或其中一个框架的不同版本。混合框架总是意味着某种未定义的行为。
如果您使用 Qt，那么我建议也使用 Qt 开发游戏（请参阅基于 Qt 的游戏）。
Pygame 不是线程安全的，因此除了数学和 pygame 中的各种其他类型的线程处理之外，它实际上不可能做任何事情。同样适用于 PyQt5，尽管有解决方法。
我找到了一种在 pyqt5 图像中嵌入和渲染 pygame 应用程序的方法。本质上，它让一个 pygame 程序在循环中产生屏幕，然后包含循环的这个函数在
QTimer()QImagepreview_widget_test.py如果您找到更好的方法（包括我的方法），请给予认可或让我知道。
