Python have many libraries for GUI. Tkinter is one of the libraries that provides a Graphical user interface. For the Short Message, we can use the MessageBox Library. It has many functions for the effective interface. In this MessageBox library provide different type of functions to Display Message Box.
- showinfo():- To display some usual Information
- showwarning():- To display warning to the User
- showerror():- To display different type of Error
- askquestion():- to Ask Query to the User
Example:
Python3
# MessageBox Illustration of showinfo() functionfrom tkinter import *from tkinter import messagebox# creating window objecttop = Tk()def Button_1(): messagebox.showinfo("Status", "Button-1 Pressed") def Button_2(): messagebox.showinfo("Status", "Button-2 Pressed")# size for windowtop.geometry("100x100")B1 = Button(top, text = "Button-1", command = Button_1) B2 = Button(top, text = "Button-2", command = Button_2) B1.pack()B2.pack()top.mainloop() |
Output:
By default, the size of the message box is Fix. We can’t change the size of that Message Box. Different Boxes have different sizes. However, we can use Different alternative methods for this purpose
- Message Widget
- By Changing ReadMe File
1. Message Widget
MessageBox library doesn’t provide the functions to change the configuration of the box. We can use the other function. The message can also be used to display the information. The size of the message is the size of the window so that we can set the size of the message by geometry, pack.
Python3
from tkinter import * main = Tk()# variable for textstr_var = StringVar()# Message Functionlabel = Message( main, textvariable=str_var, relief=RAISED ) # The size of the text determines# the size of the messageboxstr_var.set("You can't Change Your Profile Picture ") label.pack()main.mainloop() |
Output:
2. By Changing ReadMe File
This is another alternative option of the Message Box. In this, We are Opening the file readme.txt the length of the content of the readme file determines the size of the messagebox.
Input File:
Python3
from tkinter import *from tkinter import messagebox top = Tk()def helpfile(filetype): if filetype==1: with open("read.txt") as f: # reading file readme = f.read() # Display whole message messagebox.showinfo(title="Title", message = str(readme))# Driver codehelpfile(1)top.mainloop() |
Output:
