Dear Tkinter users/developers,

I'm just starting out in Python Tkinter programming, and I tried to use the
Tile module to improve the looks of the Tk program I am writing.

When I run the script written in <code></code> below, it works fine, using
the Tile module to make the Tk look ok. However, when I try to use
tkMessageBox.showwarning() as in the script, it fails with the error below.
I've tried to cat | grep for "background" in the files mentionned in the
error, but nothing turns up. I can't find where the "-background" switch is
getting stuck in. I know the "background" switch doesn't work with Tile, but
I can't find it to remove it. Any ideas please?

Here's the script:


#! /usr/bin/env python

from Tkinter import *
import tkMessageBox

def callback():
  print "called the callback!"

root = Tk()
root.tk.call('package', 'require', 'tile')
root.tk.call('namespace', 'import', '-force', 'ttk::*')
root.tk.call('ttk::setTheme', 'clam')

def callback():
  print "called the callback!"

# create a toolbar
toolbar = Frame(root)

b = Button(toolbar, text="new", width=6, command=callback)
b.pack(side=LEFT, padx=2, pady=2)

b = Button(toolbar, text="open", width=6, command=callback)
b.pack(side=LEFT, padx=2, pady=2)

toolbar.pack(side=TOP, fill=X)

status = Label(root, text="", relief=SUNKEN, anchor=W)
status.pack(side=BOTTOM, fill=X)

# create a menu
menu = Menu(root)

filemenu = Menu(menu)
menu.add_cascade(label="File", menu=filemenu)
filemenu.add_command(label="New", command=callback)
filemenu.add_command(label="Open...", command=callback)
filemenu.add_command(label="Exit", command=callback)

#tkMessageBox.showwarning("Open file","Cannot open this file\n")
