Hello all, i was just wondering how you can make a button link to another page, for instance i want the help option on my start menu to link to a help page, if you can understand this can you please supply a small snippet of code, here is my code if it will be of any use.

from Tkinter import *

def startMenu():
    top = Tk()
    top.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.pack(fill='both', expand='yes')

    ## Creates the Help Button
    frame4 = Frame(top, relief=GROOVE, borderwidth=2)
    button3 = Button(frame4, text='Help', font=('Arial', 28), fg="blue")
    button3.pack(side="left")

    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')

startMenu()

This code runs. You overwrote your root and you were missing mainloop in the end.

from Tkinter import *

root = Tk()
root.title("Checkers")
top = Canvas(root,width="800", height="800") ## !!! Was overwriting the root window
## 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.pack(fill='both', expand='yes')

## Creates the Help Button
frame4 = Frame(top, relief=GROOVE, borderwidth=2)
button3 = Button(frame4, text='Help', font=('Arial', 28), fg="blue")
button3.pack(side="left")

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')

root.mainloop() ## !!!! Was missing

Here added to previous beginnings for single window menu system (media center style).

from Tkinter import *


def create_main():
    ## 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')
    main=frame1
    ## Creates the Start Button
    frame2 = Frame(top, relief=GROOVE, borderwidth=2)
    button1 = Button(frame2, text='Start', command=go_game, 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', command=go_options, font=('Arial', 28), fg="blue")
    button2.pack(side="left")

    top.create_window(480, 550, window=frame3, anchor=SE)
    top.pack(fill='both', expand='yes')

    ## Creates the Help Button
    frame4 = Frame(top, relief=GROOVE, borderwidth=2)
    button3 = Button(frame4, text='Help', command=go_help , font=('Arial', 28), fg="blue")
    button3.pack(side="left")

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

    ## Creates the Exit Button

    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')

    return top

def create_help():
    frame = Frame(None, relief=GROOVE, borderwidth=2)
    ## Creates the Help Heading
    label1 = Label(frame, text='Help', font=('Arial', 48), fg="blue")
    label1.pack(side="left")
    
  ## Creates the Return Button
    button4 = Button(frame, text='Return',command=go_main, font=('Arial', 28), fg="blue")
    button4.pack(side="left")
    return frame

def create_options():
    frame = Frame(None, relief=GROOVE, borderwidth=2)
    ## Creates the Options Heading
    label1 = Label(frame, text='Options', font=('Arial', 48), fg="blue")
    label1.pack(side="left")

    button4 = Button(frame, text='Return',command=go_main, font=('Arial', 28), fg="blue")
    button4.pack(side="left")
    return  frame

def create_game():
    frame = Frame(None, relief=GROOVE, borderwidth=2)
    ## Creates the Game Heading
    label1 = Label(frame, text='Game', font=('Arial', 48), fg="blue")
    label1.pack()
  ## Creates the Return Button
    button4 = Button(frame, text='Return',command=go_main, font=('Arial', 28), fg="blue")
    button4.pack()
    return  frame

def go_game():
    global currentframe
    currentframe.pack_forget()
    currentframe=gameframe
    currentframe.pack()
    pass

def go_options():
    global currentframe
    currentframe.pack_forget()
    currentframe=optionsframe
    currentframe.pack()

def go_help():
    global currentframe
    currentframe.pack_forget()

    currentframe.pack()    
    
root = Tk()
root.title("Checkers")
top = Canvas(root,width="800", height="800") ## !!! Was overwriting the root window
## 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,

currentframe = mainframe = create_main()
helpframe = create_help()
optionsframe = create_options()
gameframe = create_game()

go_main() ## unnecessary, but looks nice

root.mainloop() ## !!!! Was missing

Thought out still my version of alternating colors.

Change main routine to this.

def diag_stripe(top,colors,size,cols,rows=None):
    if not rows: rows=cols ## can not put rows=cols in parameter list
    cl=len(colors)
    col=0
    squareList = []

    ## diag stripes for any size, any number of colors, rectangle
    for j in range(0,rows*size,size):
        for i in range (0,cols*size,size):
            fill=colors[col]
            squareList.append(top.create_rectangle(i,j,i+size, j+size,fill=fill))
            col=(col+1)%cl
        ## make to start with different color next line,
        ## if number of colors divides the number of cols
        if not cols % cl: col=(col+1)%cl 
    
root = Tk()
root.title("Checkers")
top = Canvas(root,width="800", height="800") ## !!! Was overwriting the root window

## Creates the alternating color square background

diag_stripe(top,["black", "white"],100,8) ## cols redundant for square
    
currentframe = mainframe = create_main()
helpframe = create_help()
optionsframe = create_options()
gameframe = create_game()

##go_main()

root.mainloop()

Maybe the squarelist need to be global or it is not needed at all.
