Question

我想知道，应用程序关闭后检查了哪些检查按钮。如果我在任何集合中保存了checkbuttons值，则在销毁应用程序后无法访问该集合。

app = Application(path_to_files)
app.initialize(data)
app.mainloop()
#i want to know all checkbuttons values on this line

好的，我稍微修改了你的代码。您将在代码中找到解释作为注释。我添加了协议方法（您可以使用self.master.protocol调用）并更改了close方法，以便在它销毁应用程序之前，它会遍历检查按钮并收集目录中的标志，然后将其转换为全局名单。

为了测试它，我必须注释掉代码的图像部分并创建我自己的游戏类以获得假游戏列表。
不知道我的解决方案是否优雅，但在我的测试条件下它是有效的。

所以在app.mainloop()尝试print(out)后，会给你一个零和一个列表。

希望它有所帮助。啊，请检查一下！当我粘贴我的代码时，这个编辑器在这里做了一些奇怪的事情。
