when I click anywhere in the textbox, the cursor always goes to the first column and row. How can I make it so that the cursor goes to the same row where the mouse cursor is?

code:

import customtkinter
from customtkinter import CTkTextbox, CTkButton, CTkFrame

def center_window(window):
screen_width = window.winfo_screenwidth()
screen_height = window.winfo_screenheight()
window_width = 1000
window_height = 700

x = int((screen_width - window_width) / 2)
y = int((screen_height - window_height) / 2)

window.geometry(f"{window_width}x{window_height}+{x}+{y}")

app = customtkinter.CTk()
app.title("SuperCool NotePad")
app.geometry("1000x700")
app.minsize(500, 300)
app.grid_columnconfigure(0, weight=1)
app.grid_rowconfigure(1, weight=1)
customtkinter.set_appearance_mode("system")
customtkinter.set_default_color_theme("blue")

button_frame = CTkFrame(app)
button_frame.grid(row=0, column=0, sticky="ew", padx=4, pady=4)

button_save = CTkButton(button_frame, text="Save")
button_save.grid(row=0, column=0, padx=(4, 2), pady=4)

button_modifica = CTkButton(button_frame, text="Modifica")
button_modifica.grid(row=0, column=1, padx=2, pady=4)

textbox = CTkTextbox(app)
textbox.grid(row=1, column=0, sticky="nsew", padx=4, pady=4)

center_window(app)

app.mainloop()

Ask your Python question, not if you can ask or if there's an expert who can help.
Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
Explain what you expect to happen and what actually happens.

Hi, it's been so long since I've used customtkinter, but I don't remember such an option in it. At least to do it directly

#

Perhaps, you can create two textboxes and remove the space between them entirely? If you want them to appear close.

hi, of course i can do that

low gull Apr 18, 2025, 8:40 PM

#

Or you could fetch the mouse click position and calculate which row the user clicked, too

#

I believe there's a method for that

brittle oriole Apr 18, 2025, 8:41 PM

#

i can try it

Is there a way to get the position of the mouse and set it as a var?

thanks

#

this is for tkinter not for customtkinter, i can see if there's a similar solution

Pretty sure, tkinter scripts can work in customtkinter. Since it's an extension of the former and all. Though, not 100% sure, do look that up too

#

there's a .cursor argument, i will try this way

Hey @brittle oriole!

Please edit your message to use a code block

```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
