Python Tkinter: TypeError: 'Frame' object is not callable

Question

I created a gui program with frames to move from page to page and I got it working while using methods only, but as soon as I introduce a class I get the following Error:

TypeError: 'Frame' object is not callable

The code I am using is as follows:

import sys
from tkinter import *
from tkinter import ttk

class teachingContent(Tk):

    def __init__(self):
        super(teachingContent, self).__init__()

        self.first_title_frame = ttk.Frame()
        self.first_frame = ttk.Frame()

    def nextButtonPressed(self):
        pass

    def prevButtonPressed(self):
        pass

    def formSize(self):
        self.geometry("650x450+200+200") # Sets the size of the gui
        self.title("Python Tutor")

        self.nbutton = Button(text = "Next", command = self.nextButtonPressed).place(x=561,y=418)

        self.pbutton = Button(text = "Previous", command = self.prevButtonPressed).place(x=0,y=418)

        title_height = 40

        self.first_title_frame(self, height=title_height, bg = 'black')
        self.first_title_frame['borderwidth'] = 2
        self.first_title_frame.grid(column=0, row=0, padx=35, pady=5, sticky=(W, N, E))


        self.first_frame(self, bg = 'DarkSlateGray4')
        self.first_frame['borderwidth'] = 2
        self.first_frame['relief'] = 'sunken'
        self.first_frame.grid(column=0, row=0, padx=33, pady=50, sticky=(W, N, E))

        self.label = Label(self.first_title_frame, text = "Welcome to the Tutor").pack()

        self.label = Label(self.first_frame, text = "Welcome to the Python Tutor. In this program you will learn to tools and techniques need to use Python.")
        self.label.grid(column=0, row=0, ipadx=85,pady=11, padx=11, sticky=(N))

tc = teachingContent()
tc.formSize()

I made a change to the code in this line adding .configure as follows:

self.first_title_frame.configure(self, height=title_height, bg = 'black')

but this gives me the following traceback:

Traceback (most recent call last):
  File "C:\Users\Tete De Bite\Dropbox\Year3\FinalYearProject\pythonTutoringSystem\debug.py", line 47, in <module>
   tc.formSize()
  File "C:\Users\Tete De Bite\Dropbox\Year3\FinalYearProject\pythonTutoringSystem\debug.py", line 31, in formSize
    self.first_title_frame.configure(self, height=title_height, bg = 'black')
  File "C:\Python33\lib\tkinter\__init__.py", line 1263, in configure
    return self._configure('configure', cnf, kw)
  File "C:\Python33\lib\tkinter\__init__.py", line 1254, in _configure
    self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: unknown option "-pady"

Does anyone have any ideas that will correct the programming mistake I am making?

Answer 1

self.first_title_frame.configure(self, height=title_height, bg = 'black')

You don't need to pass self as a parameter here.

self.first_title_frame.configure(height=title_height, bg = 'black')

In any case, ttk.Frames don't seem to allow you to directly configure their background colors. bg is not listed here under "standard options" or "widget-specific options". Try using the style argument instead, as described in this post.
