If you want more than one window, you use Tkinter.Toplevel. But I think this is
not what you want here.
A few options spring to mind..
You could build multiple frames, but only pack the one you are interested in.
eg:
from Tkinter import *
tk = Tk()
page1 = Frame(tk)
Label(page1, text='This is page 1 of the wizard').pack()
page1.pack(side=TOP)
page2 = Frame(tk)
Label(page2, text='This is page 2 of the wizard.').pack()
page3 = Frame(tk)
Label(page3, text='This is page 3. It has an entry widget too!').pack()
Entry(page3).pack()
pages = [page1, page2, page3]
current = page1
def move(dirn):
global current
idx = pages.index(current) + dirn
if not 0 <= idx < len(pages):
return
current.pack_forget()
current = pages[idx]
current.pack(side=TOP)
def next():
move(+1)
def prev():
move(-1)
Button(tk, text='Next', command=next).pack(side=BOTTOM)
Button(tk, text='Previous', command=prev).pack(side=BOTTOM)
------------------
Another option is to use Pmw.Notebook without the tabs (and with next/previous
buttons to change pages). This could be a bit easier (and it will do stuff like
making the wizard stay the same size).
Thirdly, a google search turned up this: http://www.freshports.org/devel/wizard/
