Using Tkinter in python to edit the title bar

Question

I am trying to add a custom title to a window but I am having troubles with it  I know my code isn t right but when I run it  it creates 2 windows instead  one with just the title tk and another bigger window with  Simple Prog   How do I make it so that the tk window has the title  Simple Prog  instead of having a new additional window  I dont think I m suppose to have the Tk   part because when i have that in my complete code  there s an error  from tkinter import Tk  Button  Frame  Entry  END  class ABC Frame       def   init   self parent None           Frame   init   self parent          self parent   parent         self pack           ABC make widgets self       def make widgets self           self root   Tk           self root title  Simple Prog

For anybody who runs into the issue of having two windows open, and runs across this question. Here is how I stumbled upon a solution.

The reason the code in this question is producing two windows is because

Frame.__init__(self, parent)

is being run before

self.root = Tk()

The simple fix is to run Tk() before running Frame.__init_()

self.root = Tk()
Frame.__init__(self, parent)

Why that is the case, I'm not entirely sure.

One point that must be stressed out is  The  title   function must go before the  mainloop   Example   from tkinter import      Instantiating Creating the object main menu   Tk      Set title main menu title  quot Hello World quot      Infinite loop main menu mainloop     Otherwise  this error might occur  File  quot  Library Frameworks Python framework Versions 3 8 lib python3 8 tkinter   init   py quot   line 2217  in wm title     return self tk call  wm    title   self  w  string   tkinter TclError  can t invoke  quot wm quot  command  application has been destroyed  And the title won t show up on the top frame

Try something like   from tkinter import Tk  Button  Frame  Entry  END  class ABC Frame       def   init   self  master None           Frame   init   self  master          self pack            root   Tk   app   ABC master root  app master title  Simple Prog   app mainloop   root destroy     Now you should have a frame with a title  then afterwards you can add windows for different widgets if you like

If you don t create a root window  Tkinter will create one for you when you try to create any other widget  Thus  in your   init    because you haven t yet created a root window when you initialize the frame  Tkinter will create one for you  Then  you call make widgets which creates a second root window  That is why you are seeing two windows    A well-written Tkinter program should always explicitly create a root window before creating any other widgets    When you modify your code to explicitly create the root window  you ll end up with one window with the expected title   Example   from tkinter import Tk  Button  Frame  Entry  END  class ABC Frame       def   init   self parent None           Frame   init   self parent          self parent   parent         self pack           self make widgets        def make widgets self             don t assume that self parent is a root window            instead  call  winfo toplevel to get the root window         self winfo toplevel   title  Simple Prog              this adds something to the frame  otherwise the default           size of the window will be very small         label   Entry self          label pack side  top   fill  x    root   Tk   abc   ABC root  root mainloop     Also note the use of self make widgets   rather than ABC make widgets self   While both end up doing the same thing  the former is the proper way to call the function

Having just done this myself you can do it this way   from tkinter import Tk  Button  Frame  Entry  END  class ABC Frame       def   init   self  parent None           Frame   init   self  parent          self parent   parent         self pack           ABC make widgets self       def make widgets self           self parent title  Simple Prog     You will see the title change  and you won t get two windows  I ve left my parent as master as in the Tkinter reference stuff in the python library documentation

self parent is a reference to the actual window  so self root title should be self parent title  and self root shouldn t exist
