the second of nested buttons using textvariable remains void!

2007-03-21 Thread Samkos 
Hi there,

I am fighting with a problem I intended to  believe trivial that
I could not solve yet!

I am trying to have a button with a variable text, that
pops up another button with a variable text when pressed.

I did that with the following program  in Python, but the
second button remains always void!!! is it related to
the textvariable parameters?

If any of you had a clue, please  don't hesitate!

in advance, many thanks

Samuel

#--- program 2 buttons.py

from Tkinter import *


def go(event):
root = Tk()

s1=StringVar()
s1.set(s1)
label1 = Label(root, textvariable=s1)
label1.pack(side=LEFT)

root.mainloop()



root = Tk()

s0=StringVar()
s0.set(s0)
label0 = Label(root, textvariable=s0)
label0.pack(side=LEFT)


root.bind(Return,go)

root.mainloop()

You have instantiated Tk twice which causes these kind of problems. If 
you want a window in go(), use Toplevel instead of Tk (and mainloop is 
not needed in go()). I.e.:


def go(event):
 not_root = Toplevel()

 s1=StringVar()
 s1.set(s1)
 label1 = Label(not_root, textvariable=s1)
 label1.pack(side=LEFT)
