Im using Tkinter as my GUI

from Tkinter import *

def startMenu():
    top_tk = Tk()
    top_tk.title("Checkers")
    top = Canvas(width="800", height="800")

    ## Creates the black and white square background
    size = 100
    cols = 8
    rows = 8
    squareList = []
    for i in range(cols):
        for j in range(rows):
            if j%2: colours = ["black", "white"]
            else: colours = ["white", "black"]
            squareList.append(top.create_rectangle(i*size,  j*size,
                                                   i*size+size, j*size+size,
                                                   fill=colours[i%2]))

    ## Creates the Checkers Heading
    frame1 = Frame(top, relief=GROOVE, borderwidth=2)
    label1 = Label(frame1, text='Checkers', font=('Arial', 48), fg="blue")
    label1.pack(side="left")

    top.create_window(540, 300, window=frame1, anchor=SE)
    top.pack(fill='both', expand='yes')

    ## Creates the Start Button
    frame2 = Frame(top, relief=GROOVE, borderwidth=2)
    button1 = Button(frame2, text='Start', font=('Arial', 28), fg="blue")
    button1.pack(side="left")

    top.create_window(457, 450, window=frame2, anchor=SE)
    top.pack(fill='both', expand='yes')

    ## Creates the Option Button
    frame3 = Frame(top, relief=GROOVE, borderwidth=2)
    button2 = Button(frame3, text='Options', font=('Arial', 28), fg="blue")
    button2.pack(side="left")

    top.create_window(480, 550, window=frame3, anchor=SE)

    top.create_window(458, 650, window=frame4, anchor=SE)
    top.pack(fill='both', expand='yes')

    ## Creates the Exit Button
    frame5 = Frame(top, relief=GROOVE, borderwidth=2)
    button4 = Button(frame5, text='Quit',command=quit, font=('Arial', 28), fg="blue")
    button4.pack(side="left")

    top.create_window(455, 750, window=frame5, anchor=SE)
    top.pack(fill='both', expand='yes')

    ## Not working

Hi.

Note for next time: GIVE MORE INFO!

You were having an error with the top.config() command. This is backed up by the fact that I took the not working code and changed it to this:

from Tkinter import *

root = Tk()

menubar = Menu(root)
frame = Frame()
filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="New")
filemenu.add_command(label="Open")
filemenu.add_command(label="Save")
filemenu.add_command(label="Save as...")
filemenu.add_command(label="Close")
filemenu.add_separator()
filemenu.add_command(label="Exit", command=frame.quit)
menubar.add_cascade(label="File", menu=filemenu)
root.config(menu=menubar)


root.mainloop()

it worked fine. However, this is not a top level menu.

I've had a look round but I can't see what's wrong. Now we've indentified the problem I hope that somebody can shed some light upon it...

You cannot place a menubar inside a canvas. A menubar goes on the top level window by design. You can place Tkinter widgets on a canvas by using a canvas window object.

You are assigning the name top to the top level window and the Canvas. Change the name of one of them. I messed with part of your code until it worked.

menuframe = Frame(top, relief=GROOVE, borderwidth=2)
    mb = Menubutton(top)
    mb.menu = Menu(mb)
    mb['menu'] = mb.menu
    mb.menu.add_cascade(label="text")
    top_canvas.create_window(300,300, window=menuframe, anchor=SE)

Look back through your code. You assigned the name "top" to your canvas. Your top level window is also named "top". To get it to work, I changed the name of the canvas to "top_canvas". Gees, show some effort.

def startMenu():

    top.title("Checkers")
    [B]top_canvas[/B] = Canvas(width="800", height="800")

"top" is the top level window, is it not? I renamed the canvas "top_canvas". You had the canvas named "top" also which prevented you from adding a menubar to the top level window.

You may want to do some serious editing. Rename 'top' to 'root' and call the canvas 'canvas' or something like that. I don't know how your trying to create a cascade menu, but it obviously doesn't work. Check out my tutorial:

There is an annotated link to the extension on the video.
