I am trying to integrate a python code I found here on SO by a user @srccircumflex, his code is for tkinter and I tried to modify it because I'm using customtkinter
His code was using class PassEntry(Entry): so I replaced it with class PassEntry(ctk.CTkEntry): also inside the class I replaced Entry with ctk.CTkEntry
I am a beginner in python and below is what I have so far
import customtkinter as ctk
import tkinter as tk #using messagebox
from tkinter import filedialog
from tkinter import END, INSERT, SEL_FIRST, SEL_LAST
import PyPDF2
from PyPDF2 import PdfWriter
from sys import platform
from typing import Iterable
merger = PdfWriter()
def merge_pdfs():
#code to merge pdf files
file_password = entry_password.getpass()
...
#PASSENTRY # Copyright (c) 2022 Adrian F. Hoefflin [srccircumflex] ------------------------------
class PassEntry(ctk.CTkEntry):

master,
show: chr = "*",
delay: int = 800,
getpass_range: Iterable = None,
getpass_call: ... = None,
getpass_del: bool = False,
**tk_kwargs,
):
"""
Password entry with delayed hiding. Alternative to `Entry(master, show="*")'.
Supports all common character sets(1aA!), multy keys(^`˝) and under Linux also the alternative graphics(↑Ωł).
{Deletes the input from the widget and writes it casually into a variable. Markings and the position
of the cursor is respected.}
howto get the password:
- by protected member self._password
- by calling self.getpass (args `getpass_*' executed here)
- by calling self.get (args `getpass_*' executed here)

ctk.CTkEntry.__init__(self, master, tk_kwargs)should bectk.CTkEntry.__init__(self, master, **tk_kwargs)instead. – MolliemollifyCTkEntrydoes not inherit fromEntrydirectly, so something works forEntrymay not work. – Molliemollify
