#! /usr/bin/env python3
'''Demonstration of customTKinter see TKInter documentation at https://docs.python.org/3/library/tkinter.... '''
import sys
import os
from platform import system as system_name # Returns the system/OS name
from subprocess import call as system_call # Execute a shell command

import customtkinter
'''================='''

customtkinter.set_default_color_theme("blue") # Themes: blue (default), dark-blue, green
app =customtkinter.CTk() # create CTk window like you do with the Tk window
app.geometry("230x280")
input_box = customtkinter.CTkEntry(master = app, placeholder_text = "enter text here")
input_box.pack( padx = 12, pady=20)
output_box = customtkinter.CTkEntry(master = app, placeholder_text = "Char Count")
output_box.pack( padx = 12, pady=10)
Use CTkButton instead of tkinter Button
button = customtkinter.CTkButton(master=app, text="Calculate", command=my_calculate)
button.place(relx=0.5, rely=0.6, anchor=customtkinter.CENTER)
button1 = customtkinter.CTkButton(master=app, text="Exit", command=app.destroy)
button1.place(relx=0.5, rely=0.8, anchor=customtkinter.CENTER)
app.mainloop()
except Exception as e:
print(type(e), e)
sys.exit(-1)
