python在主循環結束後得到checkbutton值

我想知道，在關閉應用程序後檢查了哪些checkbutton。如果我在任何集合中保存checkbuttons值，那麼在應用程序被銷燬後不可能訪問該集合。python在主循環結束後得到checkbutton值

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

有通常不需要做這個，但如果你真的需要，你可以有一個無論何時檢查按鈕更新調用的函數，並保存在一個變量的值。 – RobertR

如果有人知道更好的解決方案，請發帖 – gek0n

OK，我修改您的代碼位。你會在代碼中找到註釋的解釋。我添加了協議方法（您可以調用self.master.protocol）並更改了close方法，以便在它銷燬應用程序之前，它會遍歷checkbuttons並收集目錄中的標誌，然後轉換爲全局列表。

爲了測試它，我必須將代碼的圖像部分註釋掉，並創建我自己的遊戲類以獲得假遊戲列表。
不知道我的解決方案是否優雅，但在我的測試條件下工作。

所以在app.mainloop()之後嘗試print(out)，它會給你一個零和一個列表。

希望它有幫助。啊，請檢查一下！當我粘貼我的代碼時，這裏的編輯做了一些奇怪的事情。

我使用Application（）而不是'Tk（）'，所以python說沒有'protocol（）'方法。我使用我的表單作爲消息框，但內容不同。所以我每次銷燬時都需要返回值。 – gek0n

你可以發佈更多的代碼嗎？你導入了哪些模塊？我以爲「Application（）」是你自己寫的一個類？！ – JosefScript

我已添加'應用程序代碼' – gek0n
