I'm not seeing the error source in a small tkinter module I'm testing.
The module code:
-----------
import tkinter as tk
from tkinter import ttk
import common_classes as cc
class ConactNameInput(tk.Frame):
def __init__(self, parent, *args, **kwargs):
super().__init__(parent, *args, **kwargs)
# A dict to keep track of input widgets
self.inputs = {}
self.inputs['Last name'] = cc.LabelInput(
ContactNameInput, 'lname',
input_class = ttk.Entry,
input_var = tk.StringVar()
)
self.inputs['Last name'].grid(row = 0, column = 0)
#
self.inputs['First name'] = cc.LabelInput(
ContactNameInput, 'fname',
input_class = ttk.Entry,
input_var = tk.StringVar()
)
self.inputs['First name'].grid(row = 0, column = 1)
okay_button = tk.Button(self, text="OK",
command=self.ok)
okay_button.pack(side=tk.LEFT, padx=(20, 0), pady=(0, 20))
cancel_button = tk.Button(self, text="Cancel",
command=self.cancel)
cancel_button.pack(side=tk.RIGHT, padx=(0, 20), pady=(0, 20))
def okay_button(self):
pass
def cancel_button(self):
Quitter()
def get_last_name(self):
pass
def get_first_name(self):
pass
class NameApplication(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.title("Contact Name")
self.geometry("800x600")
self.resizable(width = False, height = False)
ContactNameInput(self).grid(row = 0, column = 0, sticky=('EWNS'))
self.columnconfigure(0, weight=1)
if __name__ == '__main__':
app = NameApplication()
app.mainloop()

The python error traceback:

AttributeError: type object 'ContactNameInput' has no attribute 'tk'
----------
I'm not correctly placing the NameInput class in the NameApplication frame.
What have I missed?
