如何使框架内的按钮影响其框架外的内容？我是编程新手，无法自己解决这个问题。这是我的代码和一些图片，准确地显示了我想要做的事情。任何帮助将不胜感激。

“查看游戏列表”按钮应具有与“切换到滚动框架”按钮相同的功能
我尝试让按钮运行
App.switch_frame(ScrollFrame)您尝试的 App.switch_frame(ScrollFrame) 不起作用，因为它是从类而不是实例调用函数，而实例不是您看到的窗口。所以你需要从实例“app”调用该函数。
这是 OOP 的普遍问题。您经常需要类以某种方式进行交互，这只有在每个类都引用另一个类或者实例是全局的情况下才有可能。这两种解决方案都违背了使用 OOP 的目的/优点。
对于您的情况，您可以为 FunctionsSidebarFrame 类提供对应用程序实例的引用，然后您可以使用该引用来调用其 swith_frame 函数。
class FunctionsSidebarFrame(customtkinter.CTkFrame):
def __init__(self, master, app):
self.app = app
...
def viewGames(self):
self.app.switch_frame(ScrollFrame)
这还要求您为 SidebarFrame 类提供要传递给 FunctionsSidebarFrame 的引用。
