How to change icon

[AlexsandroRP]

Hey Tom, hello. How can i change the default window icon? I tried a lot of regular tkinter methods
unsuccessfully. Thanks!

Hello,

I had the same issue, I had this "fix" for it:

root.after(201, lambda :root.iconbitmap('C:\\Users\\...\\filename.ico')) instead of root.iconbitmap('C:\\Users\\...\\filename.ico')

I hope someone will provide a better solution

[amezolaMartin]

It worked! Thaks a lot.

What do we do when we inherit a class with self?

@Maaz4226
replace the root with self.window in your case

@Maaz4226 replace the root with self.window in your case

Your code is correct but I wrote a lot of code with self so I wrote this code "self.window.iconbitmap()"

If you use the latest version there should be no problem.

[AlexsandroRP]

@IAminos Thanks a lot, that was the only method that worked!

[Tcrozly]

This issue still effects CTkToplevel, using the suggestion from IAminos solved my issue. thanks!

Has anyone gotten this to cooperate on macOS? I made sure the latest version of CustomTkinter is running. Using the regular app.iconbitmap(PATH_HERE) does not cooperate, nor does the solution presented by IAminos :(

[liquidz00]

I'm a bit of a novice with coding, you'll have to forgive me. I assume you mean app.iconphoto(<image variable here>) assuming app = customtkinter.CTk()? Would you be able to provide an example of the method implementation?

[avalon60]

Well, in my example, you need to assume that I am in the context of a class based on CTk(), or CTkTopLevel. So instead of app... I am referencing it as self...

That said, it appears you might be missing a parameter. See here.

@avalon60 We cannot change that default python taskbar icon on windows. But if you compile it to exe, then it will work properly.

[liquidz00]

@avalon60 Going to be honest I hyper-focused on @Akascape 's response and glossed over your reply, I didn't realize you were also using said method.

I'm using classes, both application-specific and inheriting from customtkinter. I originally tried setting that property on self, but the issue persisted. I have since put this to the side as I'm curious to see in testing what PyInstaller can do instead. Thank you though!

[Akascape]

@aspeciale Please try this method: #1099 (comment)

[Akascape]

Try this method:

For root window:

import os
from PIL import ImageTk
...

self.iconpath = ImageTk.PhotoImage(file=os.path.join("assets","logo.png"))
self.wm_iconbitmap()
self.iconphoto(False, self.iconpath)

For toplevels:

self.wm_iconbitmap()
self.after(300, lambda: self.iconphoto(False, self.iconpath))

[liquidz00]

The root window did the trick! Thank you so much @Akascape !

@TomSchimansky Hi Tom , wie kann ich meine GUI 'logo' wechseln mit customtkinter. Es ist unverbesserlich wann ich die Gleiche Logo für Jede Python GUI habe.

[bukdk]

import customtkinter as ctk
import tkinter as tk
import sys
import os
from pathlib import Path
from PIL import ImageTk
from pathlib import Path

class App(ctk.CTkFrame):
def init(self, master):
super().init(master)

    self.master = master

    # Disable the Close Window Control Icon depends on the operating system
    if sys.platform == "linux":
        self.overrideredirect(True)
    elif sys.platform == "darwin":  # OS X
        pass
    else:  # win32
        self.master.protocol("WM_DELETE_WINDOW", self.disable_event)
 
    self.pfad = os.path.dirname(__file__)
    os.chdir(self.pfad)
    self.iconpath = ImageTk.PhotoImage(
        file=os.path.join("resources/images", "logo.ico")
    )
    self.master.wm_iconbitmap()
    self.master.iconphoto(False, self.iconpath)
    # but for a CTkToplevel you have to change self.master.iconphoto(False, self.iconpath) to
    # self.after(300, lambda: self.iconphoto(False, self.iconpath))

    self.create_widgets()

def create_widgets(self):
    '...'

root = ctk.CTk()
root.title("Test App")
root.fg_color = "#161C25"
app = App(root)
root.eval(f"tk::PlaceWindow {str(root)} center")
app.mainloop()

This worked for me (KDK)

[zhanglei-55]

Something like this:

# Importing required module
import customtkinter as ctk

# Selecting GUI theme : dark,light , system (for system default)
ctk.set_appearance_mode("system")

# Selecting color theme-blue, green, dark-blue
ctk.set_default_color_theme("dark-blue")

app = ctk.CTk()
app.geometry("400x400")
app.title("Modern Login UI using Customtkinter")
openstack_icon = app.iconbitmap('openstack.ico')
