My question refers to this video:
At time 3:46 she runs the code for root widget:
from tkinter import ttk
root = tk.Tk()
root.mainloop()
No problem there, I get the same too.
However, at time 5:37 when she runs the widget code to display the "Forest" theme I get this error message.
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
style = ttk.Style(root)
root.tk.call("source", "forest-light.tcl")
root.tk.call("source", "forest-dark.tcl")
style.theme_use("forest-dark")
root.mainloop()
Traceback (most recent call last):
File "address to filename", line 8, in <module>
root.tk.call('source', 'forest-light.tcl')
_tkinter.TclError: invalid command name "<!DOCTYPE"
I have tried including an asterisk at the first import line as I thought it's a version issue. No change
I even tried re-downloading the tcl files from the referred to GitHub page as I thought the files might be the problem. No headway
I am a beginner using Python 3.12. Thanks in advance for your advice.
You're trying to source a file that is expected to be Tcl code, but instead, the first line of the file begins with <!DOCTYPE. That means it's not tcl code. Instead, it is an html or xml file. You probably downloaded forest-light.tcl and/or forest-dark.tcl incorrectly.
