Tkinter Text editor not showing menu widgets

Question

I am attempting to remake notepad through python the problem is my menu won't pack. I am using the tkinter module. So far the attempted product should be a text box with a menu bar above it. clicking on each menu button should pull up a mean. I did not write any functions for each menu option yet so I know all of my "add_command"s don't have a command

from tkinter import *
import tkinter.messagebox
import tkinter

# Text Box
class ScrolledText(Frame):
        def __init__(self, parent=None, text='', file=None):
                Frame.__init__(self, parent)
        self.pack(expand=YES, fill=X)               #make expandable
        self.makewidgets()
        self.settext(text,file)

    def makewidgets(self):
        sbar = Scrollbar(self)
        text = Text(self, relief=SUNKEN)
        sbar.config(command=text.yview)                 # xlink sbar and text
        text.config(yscrollcommand=sbar.set)            # moving one moves other
        sbar.pack(side=RIGHT, fill=Y)                   #pack first-clip last
        text.pack(side=LEFT, expand=YES, fill=BOTH)     # text clipped first
        self.text = text

def settext(self, text='', file=None):
    if file:
        text = open(file, 'r').read()
    self.text.delete('1.0', END)
    self.text.insert('1.0', text)
    self.text.mark_set(INSERT, '1.0')
    self.text.focus()

def gettext(self):
    return self.text.get('1.0', END+'-1c')

Answer 1

It is highly unusual to make menu buttons as children of a scrolled text widget. The proper way to make a menubar is to create a menu (not a menubutton), and then attach the menu to the root:

    menubar = tk.Menu(root)
    root.configure(menu=menubar)
    fileMenu = tk.Menu(menubar)
    menubar.add_cascade(label="File", menu=fileMenu)
    ...

Doing it this way guarantees you get a proper, native menubar.
