Why isn t ico file defined when setting window s 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  lt module gt      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

I recently ran into this problem and didn t find any of the answers very relevant so I decided to make a SO account for this  Solution 1  Convert your  ico File online there are a lot of site out there Solution 2  Convert  ico File in photoshop If you or your Editor just renamed your image file to   ico then it is not going to work  If you see the image icon from your Windows OS folder then it is working

Try this   from tkinter import   import os import sys  root   Tk   root iconbitmap os path join sys path 0     lt your-ico-file gt      root mainloop     Note  replace  lt your-ico-file gt  with the name of the ico file you are using otherwise it won t work   I have tried this in Python 3  It worked

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   gt  gt  gt  get dir  test txt    C  Users Josua Desktop test txt    EDIT  The only issue is that this method dosn t work on linux  josua raspberrypi     python Python 2 7 9  default  Sep 17 2016  20 26 04   GCC 4 9 2  on linux2 Type  help    copyright    credits  or  license  for more information   gt  gt  gt  import sys  gt  gt  gt  sys argv 0      gt  gt  gt

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

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

I m using Visual Studio Code  To make  quot favicon ico quot  work  you need to specify in which folder you are working   You press ctrl   shift   p to open the terminal cmd shift p on OSX  In the terminal  you type  cd   the path where you are working  For example  cd C  User Desktop MyProject

I had the same problem too  but I found a solution  root mainloop   from tkinter import          must add root   Tk   root title  quot Calculator quot   root iconbitmap r quot image icon ico quot        root mainloop    In the example  what python needed is an icon file  so when you dowload an icon as  png it won t work cause it needs an  ico file  So you need to find converters to convert your icon from png to ico
