How to create a message box with tkinter?

I've been trying to build a fairly simple message box in tkinter that has "YES" and "NO" buttons. When I push the "YES" button internally it must go and write YES to a file. Similarly, when "NO" is pushed, NO must be written to a file. How can I do this?

You can use message box from Tkinter using

# For python 3 or above
from tkinter import messagebox

# For python less than 3
from Tkinter import *
import tkMessageBox

Here's the basic syntax:

messagebox.Function_Name(title, message [, options])

The message boxes are modal and will return a subset of (True, False, OK, None, Yes, No) based on the user’s selection.

So to get the value of message box you just need to store the value in a variable. An example is given below:

res=mb.askquestion('Exit Application', 'Do you really want to exit')
if res == 'yes' :
    root.destroy()

There are different type of message boxes or Function_name:

  1. showinfo(): Show some relevant information to the user.
  2. showwarning(): Display the warning to the user.
  3. showerror(): Display the error message to the user.
  4. askquestion(): Ask question and user has to answered in yes or no.
  5. askokcancel(): Confirm the user’s action regarding some application activity.
  6. askyesno(): User can answer in yes or no for some action.
  7. askretrycancel(): Ask the user about doing a particular task again or not.
  8. Message: creates a default information box, or is same as showinfo box.
messagebox.Message(master=None, **options)
# Create a default information message box.

You can even pass your own title and message in it.

Things you can pass in the message boz:

  • title: This parameter is a string which is shown as a title of a message box.
  • message: This parameter is the string to be displayed as a message on the message box.
  • options: There are two options that can be used are:
    1. default: This option is used to specify the default button like ABORT, RETRY, or IGNORE in the message box.
    2. parent: This option is used to specify the window on top of which the message box is to be displayed.

Here's how you can ask a question using a message box in Python 2.7. You need specifically the module tkMessageBox.

from Tkinter import *
import tkMessageBox


root = Tk().withdraw()  # hiding the main window
var = tkMessageBox.askyesno("Title", "Your question goes here?")

filename = "log.txt"

f = open(filename, "w")
f.write(str(var))
print str(var) + " has been written to the file " + filename
f.close()

You can use the module tkMessageBox for Python 2.7 or the corresponding version for Python 3 called tkinter.messagebox.

It looks like askquestion() is exactly the function that you want. It will even return the string "yes" or "no" for you.

You can assign the return value of the askquestion function to a variable, and then you simply write the variable to a file:

from tkinter import messagebox

variable = messagebox.askquestion('title','question')

with open('myfile.extension', 'w') as file: # option 'a' to append
    file.write(variable + '\n')
