the iconphoto () method in Tkinter | python

Syntax :

 iconphoto (self, default = False, * args) 

Steps to set the icon image —

 from tkinter import Tk master = Tk () photo = PhotoImage (file = "Any image file") master.iconphoto (False, photo) 

Set the title icon for this window based on named photo images passed through args . If default — this also applies to all future tops created. The data in the images is received as a snapshot during a call. If the images are subsequently changed, this is not reflected in the header icons. The function also scales the provided icons to the appropriate size.

Code # 1: When PhotoImage is provided.

# Importing a Tkinter Module from tkinter import * from tkinter.ttk import *    # Create the main Tkinter window master = Tk ()    # Create a photo class object # The image must be in the same p Apk # where the script is saved p1 = PhotoImage ( file = ’info.png’ )    # Setting the main window icon master.iconphoto ( False , ’info.png’ )   # Create button b = Button (master, text = ’Click me!’ ) b.pack ( side = TOP)   # Infinite loop can be interrupted # keyboard or mouse interruption # or any predefined function (destroy () ) mainloop ()

Output:

Exception: if you provide an image directly instead of a PhotoImage then the following error will be displayed.

Code # 2: when no PhotoImage is provided

# Import Tkinter module from tkinter impo rt * from tkinter.ttk import *   # Create the main Tkinter window master = Tk ()   # Customize the main window icon master.iconphoto ( False , ’info.png’ )    # Create button b = Button (master, text = ’Click me!’ ) b.pack (side = TOP)    # Endless loop can be interrupted # keyboard or mouse interruption # or any predefined function (destroy ()) mainloop ()
