如何从 tkinter 调用消息框？
[英]How to call messagebox from tkinter?
问题描述
I'm creating a Tkinter-based GUI in Python and I have a problem: messagebox does not appear when I'm getting data from the Entry widget.
我正在用 Python 创建一个基于 Tkinter 的 GUI，但我遇到了一个问题：当我从 Entry 小部件获取数据时没有出现消息框。 How can I solve it?我该如何解决？
from tkinter import *
import random
win = Tk()
win.title("Sample")
win.resizable(False, False)
win.configure(bg="#767676")
def game():
entry = Entry_field.get()
days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Sunday", "Saturday"]
randomise = random.choice(days)
messagebox.showinfo("Ответ", randomise)
Label_field = Label(win, text="Choose your day!", font=("outrun", 10, "bold"))
Label_field.grid(row=0, column=0)
Notification_Label = Label(win, text="Enter your name here", font=("montserrat", 10, "bold"), bg="#EF9A9A")
Notification_Label.grid(row=1, column=0, sticky=W)
Entry_field = Entry(win, width=30)
Entry_field.grid(row=1, column=1)
Button_field = Button(win, text="Press", command=game)
Button_field.grid(row=1, column=2)
win.mainloop()

You are trying to use the showinfo function from the tkinter.messagebox module, but haven't imported it.您正在尝试使用tkinter.messagebox模块中的showinfo函数，但尚未导入它。 You need to add import tkinter.messagebox as messagebox or from tkinter import messagebox line to the top of your code.您需要将import tkinter.messagebox as messagebox或from tkinter import messagebox import tkinter.messagebox as messagebox from tkinter import messagebox行添加到代码的顶部。 Here is the full fixed code:这是完整的固定代码：
from tkinter import *
import tkinter.messagebox as messagebox
import random
win = Tk()
win.title("Sample")
win.resizable(False, False)
win.configure(bg="#767676")
def game():
entry = Entry_field.get()
days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Sunday", "Saturday"]
randomise = random.choice(days)
messagebox.showinfo("Ответ", randomise)
Label_field = Label(win, text="Choose your day!", font=("outrun", 10, "bold"))
Label_field.grid(row=0, column=0)
Notification_Label = Label(win, text="Enter your name here", font=("montserrat", 10, "bold"), bg="#EF9A9A")
Notification_Label.grid(row=1, column=0, sticky=W)
Entry_field = Entry(win, width=30)
Entry_field.grid(row=1, column=1)
Button_field = Button(win, text="Press", command=game)
Button_field.grid(row=1, column=2)
win.mainloop()
