I am fairly new to python and very new to GUI's so please let me know if I have made an obvious mistake.
This is also my first post so please let me know if I need to edit my question in some way.
I don't understand why I am getting errors when trying to set an icon to a tkinter GUI. I have already tried the following posts:
tkinter TclError: error reading bitmap file
https://www.delftstack.com/howto/python-tkinter/how-to-set-window-icon-in-tkinter/
There are other stack exhange posts on this topic but they are for windows and/or their OP's normally can get the icon to apear once then it doesn't work. This isn't my situation the programs fail to run. Though I have tried some of their suggestions as well.
I have tried three different ways of coding this: Method 1:
from tkinter import *
import os
class MainWindow:
def __init__(self, master):
self.master = master
master.title('TD')
#self.iconbitmap(default = 'fist.ico')
root = Tk()
root.iconphoto(True, PhotoImage(os.path.join(os.getcwd(),'favicon-3.png')))
my_gui = MainWindow(root)
root.mainloop()
Result:
runfile('~./envs/thermTD_project/thermTD/untitled2.py', wdir='~./envs/thermTD_project/thermTD')
Traceback (most recent call last):
File "~./envs/thermTD_project/thermTD/untitled2.py", line 23, in <module>
root.iconphoto(True, PhotoImage(os.path.join(os.getcwd(),'favicon-3.png')))
File "/usr/lib/python3.8/tkinter/__init__.py", line 2116, in wm_iconphoto
self.tk.call('wm', 'iconphoto', self._w, "-default", *args)
TclError: can't use "~./envs/thermTD_project/thermTD/favicon-3.png" as iconphoto: not a photo image
File existence check:
In [42]: os.path.exists(os.path.join(os.getcwd(),'favicon-3.png'))
Out[42]: True
Method 2:
from tkinter import *
import os
class MainWindow:
def __init__(self, master):
self.master = master
master.title('TD')
#self.iconbitmap(default = 'fist.ico')
root = Tk()
root.iconbitmap(os.path.join(os.getcwd(),'favicon-3.ico'))
my_gui = MainWindow(root)
root.mainloop()
Result:
In [43]: runfile('~./envs/thermTD_project/thermTD/untitled2.py', wdir='~./envs/thermTD_project/thermTD')
Traceback (most recent call last):

root.iconbitmap(os.path.join(os.getcwd(),'favicon-3.ico'))
File "/usr/lib/python3.8/tkinter/__init__.py", line 2071, in wm_iconbitmap
return self.tk.call('wm', 'iconbitmap', self._w, bitmap)
TclError: bitmap "~./envs/thermTD_project/thermTD/favicon-3.ico" not defined
File existence check:

Method 3:
from tkinter import *
import os
class MainWindow:
def __init__(self, master):
self.master = master
master.title('TD')
#self.iconbitmap(default = 'fist.ico')
root = Tk()
img = PhotoImage(os.path.join(os.getcwd(),'favicon-3.ico'))
root.tk.call('wm','iconphoto', root._w, img)
my_gui = MainWindow(root)
root.mainloop()
Result:
In [45]: runfile('~./envs/thermTD_project/thermTD/untitled2.py', wdir='~./envs/thermTD_project/thermTD')
Traceback (most recent call last):
File "~./envs/thermTD_project/thermTD/untitled2.py", line 21, in <module>
root.tk.call('wm','iconphoto', root._w, img)
TclError: can't use "~./envs/thermTD_project/thermTD/favicon-3.ico" as iconphoto: not a photo image
File existence check: See method 1
The code without any of the icon setting lines works as expected.
I have tried to gif, png and ico on each method. I am trying other file types now.
NB: While the filename is favicon actually they are ico, gif, png files of 64x64 pixles. Even the favicon ico only has 1 type of icon in it (if thats the right phrase). Its just I got them from a favicon which I converted to different formats using mogrify.
OS: Ubuntu 20.04.1 LTS python 3.8.2 IDE: spyder 4.1.5
P.S. I would be gratefull to know what the syntax for including this in my init function. I am trying to do object orientated GUI's I am very much still learning.
