Maybe you could use a Pmw.NoteBook and disable the tab buttons, like this
(untested):
from Tkinter import *
import Pmw
root = Tk()
Pmw.initialise(root)
nb = Pmw.NoteBook(root)
nb.pack(side='top', fill='both', expand=1)
def next_page():
pages = nb.pagenames()
current = nb.getcurselection()
# maybe more testing and changing the button's text here
if current == pages[-1]:
nb.selectpage(pages[0])
else:
nb.nextpage()
b = Button(root, text='Next page', command=next_page)
b.pack(side='bottom')
firstpage = nb.add('firstpage', tab_text='First page', tab_state='disabled',
tab_disabledforeground='black')
(...)# add widgets and more pages
root.mainloop()
I hope this helps
Michael
