Python Tkinter-时间或单击后销毁窗口 [英] Python Tkinter - destroy window after time or on click

问题描述

我有以下代码:

import tkinter as tk
from tkinter import messagebox

try:
    w = tk.Tk()
    w.after(3000, lambda: w.destroy()) # Destroy the widget after 3 seconds
    w.withdraw()
    messagebox.showinfo('MONEY', 'MORE MONEY')
    if messagebox.OK:
        w.destroy()
    w.mainloop()
    confirmation = 'Messagebox showed'
    print(confirmation)
except Exception:
    confirmation = 'Messagebox showed'
    print(confirmation)

是否有更好的方法可以执行此操作而不使用线程和捕获异常?

Is there better way to do this, without using threading and catching exception?

推荐答案

您使用if messagebox.OK:，但是messagebox.OK被定义为OK = "ok".因此，您的if语句始终为true.如果要检查用户是否单击了按钮，则需要获取showinfo函数的返回值.

You use if messagebox.OK:, but messagebox.OK is defined as OK = "ok". Therefore, your if statement is always true. If you want to check whether the user clicked the button you need to get the return value of the showinfo function.

因此您可以这样做:

a = messagebox.showinfo('MONEY', 'MORE MONEY')
if a:
    w.destroy()

或更短:

if messagebox.showinfo('MONEY', 'MORE MONEY'):
    w.destroy()

当用户未单击任何内容时(因此w.destroy调用已运行w.destroy时)，不会运行w.destroy.

This way w.destroy is not run when the user didn't click anything (so when w.destroy has already been run by the after call).

总计:

import tkinter as tk
from tkinter import messagebox

w = tk.Tk()
w.withdraw()
w.after(3000, w.destroy) # Destroy the widget after 3 seconds
if messagebox.showinfo('MONEY', 'MORE MONEY'):
    w.destroy()

confirmation = 'Messagebox showed'
print(confirmation)
