hi all,

this Tkinter very simple code work fine:

##########################
from Tkinter import *

win = Tk()
win.mainloop()
##########################

but if I try to open a message box, it happens:

Exception in Tkinter callback
Traceback (most recent call last):

##############################
from Tkinter import *
from tkMessageBox import *

def reply():
showinfo(title='ciao', message='hello')

win = Tk()
but = Button(win, text='press me', command=reply)
but.pack()
win.mainloop()
##############################

these are versions:

python: 2.4.4 or 2.5.1
Tkinter.TclVersion: 8.4
Tkinter.TkVersion: 8.4

can anyone help me?
thanks

I'm not sure, but I don't think you need the "win" variable at all. I
can get it to work as follows:

<code>

from Tkinter import *
from tkMessageBox import showinfo

def reply():
showinfo(title='ciao', message='hello')

Button(text='press me', command=reply).pack(fill=X)
mainloop()

</code>
