Re: Centering grid inside a frame

Use an empty row and column surrounding your other widgets, and give those
rows and columns a weight. That is, leave row and column 0 empty, and the
row and column below and to the right of all the other widgets empty. With
a non-zero weight, and with the non-empty rows/columns with a default
weight of zero, the empty rows and columns  will be given all extra room,
effectively centering the other widgets.

from Tkinter import *

tk = Tk()
Button(tk, text="button1").grid(row=1, column=1, sticky=NSEW)
Button(tk, text="button2").grid(row=1, column=2, sticky=NSEW)
Button(tk, text="button3").grid(row=2, column=1, sticky=NSEW)
Button(tk, text="button4").grid(row=2, column=2, sticky=NSEW)

tk.grid_rowconfigure(0, weight=1)
tk.grid_rowconfigure(3, weight=1)
tk.grid_columnconfigure(0, weight=1)
tk.grid_columnconfigure(3, weight=1)

tk.mainloop()
