Set window icon

Question

When I tried to change the window icon in the top left corner from the ugly red "TK" to my own favicon using the code below, Python threw an error:

from tkinter import *
root = Tk()

#some buttons, widgets, a lot of stuff

root.iconbitmap('favicon.ico')

This should set the icon to 'favicon.ico' (according to a lot of forum posts all over the web). But unfortunately, all this line does is throw the following error:

Traceback (most recent call last):
  File "d:\ladvclient\mainapp.py", line 85, in <module>
    root.iconbitmap(bitmap='favicon.ico')
  File "C:\Python33\lib\tkinter\__init__.py", line 1637, in wm_iconbitmap
    return self.tk.call('wm', 'iconbitmap', self._w, bitmap)
_tkinter.TclError: bitmap "favicon.ico" not defined

What I already did:

• I checked the path - everything is 100% correct
• I tried other file formats like .png or .bmp - none worked
• I looked this problem up on many websites

And for the third point, effbot.org, my favorite site about Tkinter, told me that Windows ignores the iconbitmap function. But this doesn't explain why it throws an error!

There are some "hackish" ways to avoid that issue, but none of them are written for Python 3.x.

So my final question is: Is there a way to get a custom icon using Python 3.x and Tkinter?

Also, don't tell me I should use another GUI Library. I want my program to work on every platform. I also want a coded version, not a py2exe or sth solution.

Answer 1

You must not have favicon.ico in the same folder as your script or, namely, on your path. Put in the full pathname. For example, this works:

from tkinter import *
root = Tk()

root.iconbitmap(r'c:\Python32\DLLs\py.ico')
root.mainloop()

But this blows up with your same error:

from tkinter import *
root = Tk()

root.iconbitmap('py.ico')
root.mainloop()

Answer 2

No way what is suggested here works - the error "bitmap xxx not defined" is ever present. And yes, I set the correct path to it.

What it did work is this:

imgicon = PhotoImage(file=os.path.join(sp,'myicon.gif'))
root.tk.call('wm', 'iconphoto', root._w, imgicon)  

where sp is the script path, and root the Tk root window.

It's hard to understand how it does work (I shamelessly copied it from fedoraforums) but it works

Answer 3

This works for me with Python3 on Linux:

import tkinter as tk

# Create Tk window
root = tk.Tk()

# Add icon from GIF file where my GIF is called 'icon.gif' and
# is in the same directory as this .py file
root.tk.call('wm', 'iconphoto', root._w, tk.PhotoImage(file='icon.gif'))

Answer 4

#!/usr/bin/env python
import tkinter as tk

class AppName(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit', command=self.quit)
        self.quitButton.grid()

app = AppName()
app.master.title('Title here ...!')
app.master.iconbitmap('icon.ico')
app.mainloop()

it should work like this !

Answer 5

Both codes are working fine with me on python 3.7..... hope will work for u as well

import tkinter as tk
m=tk.Tk()
m.iconbitmap("myfavicon.ico")
m.title("SALAH Tutorials")
m.mainloop()

and do not forget to keep "myfavicon.ico" in the same folder where your project script file is present

Another method

from tkinter import *
m=Tk()
m.iconbitmap("myfavicon.ico")
m.title("SALAH Tutorials")
m.mainloop()

[*NOTE:- python version-3 works with tkinter and below version-3 i.e version-2 works with Tkinter]

Answer 6

Got stuck on that too...

Finally managed to set the icon i wanted using the following code:

from tkinter import *
root.tk.call('wm', 'iconphoto', root._w, PhotoImage(file='resources/icon.png'))

Answer 7

Make sure the .ico file isn't corrupted as well. I got the same error which went away when I tried a different .ico file.

Answer 8

So it looks like root.iconbitmap() only supports a fixed directory.
sys.argv[0] returns the directory that the file was read from so a simple code would work to create a fixed directory.

import sys
def get_dir(src):
    dir = sys.argv[0]
    dir = dir.split('/')
    dir.pop(-1)
    dir = '/'.join(dir)
    dir = dir+'/'+src
    return dir

This is the output

>>> get_dir('test.txt')
'C:/Users/Josua/Desktop/test.txt'

EDIT:
The only issue is that this method dosn't work on linux

>>> import sys
>>> sys.argv[0]
''

from tkinter import *
from PIL import ImageTk, Image

Tk.call('wm', 'iconphoto', Tk._w, ImageTk.PhotoImage(Image.open('./resources/favicon.ico')))

The above worked for me.
