How can I reprogram the 'Ok' button in the Tkinter Messagebox module

Question

我正在使用我的第一个Python GUI，在单击消息的“确定”按钮后，我想从代码中关闭所有以前的窗口

messagebox.showinfo('Access Granted', 'Your data has been retrieved.')

Answer 1

The tkinter dialogs return a string representing what the user clicked on, so it's just a matter of saving that value and checking it afterwards. However, since showinfo only gives the user one option it's always going to return "ok" , so there's no need to check the value. Just call your function after the dialog has been displayed:

def some_function():
    messagebox.showinfo('Access Granted', 'Your data has been retrieved.')
    root.destroy()
...
button = tk.Button(root, text="Quit", command=some_function)

Answer 2

So, say if your window was called root you would want to first define a function to 'destroy' the window

def closeWindow():
    root.destroy()

Then you'd want to add that command to the button -

btn = tkinter.Button(text="Click Me!" command=closeWindow)

If you get any more errors, let me know!
