[Tutor] Tkinter Grid, Listbox expand

[W W]

Hi,

I'm writing a Tkinter program and having severe problems with getting
my listbox to expand when I resize the window.

Here's my code so far:

  1 from Tkinter import *
  2 import os, shutil, tkFileDialog, tkMessageBox
  3
  4 class TkSync:
  5     def __init__(self, root):
  6         self.sbox = Listbox(root)
  7         self.sbox.grid(row=0, column=0, sticky=N+S+E+W)
  8         root.grid_rowconfigure(0, minsize=400)
  9         root.grid_columnconfigure(0, minsize=400)
 10
 11 root = Tk()
 12 TkSync(root)
 13 root.mainloop()


When I run that, it sizes right to start out... but then it won't get
any bigger. I've tried various different combinations and nothing has
worked quite right.

TIA,
Wayne
