Tkinter中的不同消息|Python _Tkinter

Tkinter提供一个留言框可用于显示各种消息的类, 以便用户可以根据这些消息进行响应。消息, 如确认消息, 错误消息, 警告消息等。
为了使用该类, 必须导入该类, 如下所示：

# import all the functions and constants of this class. from tkinter.messagebox import *

此类的语法和不同功能的使用–

askokcancel(title=None, message=None, **options)# Ask if operation should proceed; # return true if the answer is ok.askquestion(title=None, message=None, **options)# Ask a question.askretrycancel(title=None, message=None, **options)# Ask if operation should be retried; # return true if the answer is yes.askyesno(title=None, message=None, **options)# Ask a question; return true # if the answer is yes.askyesnocancel(title=None, message=None, **options)# Ask a question; return true # if the answer is yes, None if cancelled.showerror(title=None, message=None, **options)# Show an error message.showinfo(title=None, message=None, **options)# Show an info message.showwarning(title=None, message=None, **options)# Show a warning message.

演示各种消息的程序：

# importing messagebox class from tkinter.messagebox import *# Showing various messaesprint (askokcancel( "askokcancel" , "Ok or Cancel" ))print (askquestion( "askquestion" , "Question?" ))print (askretrycancel( "askretrycancel" , "Retry or Cancel" ))print (askyesno( "askyesno" , "Yes or No" ))print (askyesnocancel( "askyesnocancel" , "Yes or No or Cancel" ))print (showerror( "showerror" , "Error" ))print (showinfo( "showinfo" , "Information" ))print (showwarning( "showwarning" , "Warning" ))# print statement is used so that we can # print the returned value by the function

输出如下：
