Color substring of text among Textbox

[MoritzNekolla]

Hello,

is there a possibility to color just a substring of the text inside a customtinker.Textbox? Or highlight it otherwise?

In plain tkinter this is possible like so:

import tkinter as tk

# Create a new tkinter window
root = tk.Tk()

# Create a Text widget
text_widget = tk.Text(root, height=10, width=50)
text_widget.pack()

# Add text to the Text widget
text_widget.insert('end', 'This is some colored text.\n')

# Add a tag to color a substring
text_widget.tag_add('color', '1.5', '1.11') # '1.5' means first line, 5th character; '1.11' means first line, 11th character

# Configure the tag to set the text color
text_widget.tag_configure('color', foreground='red')

# Run the tkinter event loop
root.mainloop()

However customtinker only provides the text_color parameter, which colors the whole Text.

Any ideas?

Works fine, but the method is called tag_config as in the tkinter docs. It's really confusing in tkinter that there exist multiple names for the same method. I only wrapped tag_config for CustomTkinter.

import customtkinter

app = customtkinter.CTk()

text_widget = customtkinter.CTkTextbox(app)
text_widget.pack()

text_widget.insert('end', 'This is some colored text.\n')
text_widget.tag_add('color', '1.5', '1.11')  # '1.5' means first line, 5th character; '1.11' means first line, 11th character
text_widget.tag_config('color', foreground='red')

app.mainloop()
