在这个程序中，我希望时间在每个按钮上继续，即使另一个按钮被点击，但是，当另一个按钮被点击时，时间似乎停止在一个按钮上，我在这里有什么建议吗？

self.Button3.update()
os.system('cls')

最佳答案
你的问题是来自 tkinter 的 Button 只是在用户点击那个按钮时才执行命令功能。因此，当用户单击另一个按钮时，该命令函数将停止/终止并更改为单击的按钮命令函数。这就是计时器停止的主要原因!
这个问题有两种解决方案:
最简单的方法是将您的计时器(例如 Button1 分钟、秒、Button2 分钟、秒...)存储为属性，并使用 tkinter Label 显示计时器它们中的每一个都在界面上，而不是处理关于按钮的问题，因为只要用户点击按钮，命令功能将始终停止并更改为另一个。
解决这个问题的另一种方法是使用 Button 小部件中的
.invoke()方法来回调来自先前单击按钮的命令功能。如果你想使用这种方式，你可以在这个链接上查看这个方法是如何工作的:http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/button.html
P/S:我也喜欢英雄联盟!

这是我的计时器代码演示，请查看!我对根窗口使用了 .after() 方法。此外，我将所有时间数据存储为对象属性，因此更易于访问!
