Tkinter Messagebox - 保存Messagebox答案（例如，用户选择“是”或“否”）

Question

所以我在Python 3.6中编写了一个应用程序，但我似乎找不到如何获取消息框答案值（是或否）的答案。

fileSavedExit = True
def msgbox1():
    if fileSavedExit == True:
        root.destroy()  
    if fileSavedExit == False:
        messagebox.askyesno('Save File ?','Do you want to save the file first?')

这样的事情。我正在寻找可以保存答案的代码（'Yes'或'No'）。如果有人能帮助我，我将感激不尽。 ：o

Answer 1

如果答案是askyesno，那么

True会返回"Yes"，如果答案是False，则"No"会返回if/else。您只需使用try: # In order to be able to import tkinter for import tkinter as tk # either in python 2 or in python 3 import tkinter.messagebox as tkmb except ImportError: import Tkinter as tk import tkMessageBox as tkmb def ask(): response = tkmb.askyesno("Messagebox Title", "Is this it?") global button if response: # If the answer was "Yes" response is True button['text'] = "Yes" else: # If the answer was "No" response is False button['text'] = "No" if __name__ == '__main__': root = tk.Tk() button = tk.Button(root, text="Ask...", command=ask) button.pack() tk.mainloop() 过滤它。
