Why isn't .ico file defined when setting window's icon?

Solution 1:

You need to have favicon.ico in the same folder or dictionary as your script because python only searches in the current dictionary or you could 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()

Solution 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

Solution 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'))

Solution 4:

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'))

Solution 5:

#!/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 !
