Tkinter: making buttons the same size?

[skanemupp]

on windows vista these buttons dont have the same size, the "/"
shrinks a little. how do i make them the same size or prevent
shrinking?
a mac-user told me they look the same to him so maybe it doesnt shrink
on macs but it does when using VISTA.

i tried some .propagate and extend-stuff but didnt work.

#! /usr/bin/env python
from Tkinter import *
import tkMessageBox

class GUIFramework(Frame):
"""This is the GUI"""

def __init__(self, master=None):
"""Initialize yourself"""

"""Initialise the base class"""
Frame.__init__(self,master)

"""Set the Window Title"""
self.master.title("Calculator")

"""Display the main window"
with a little bit of padding"""
self.grid(padx=10,pady=10)
self.CreateWidgets()



def CreateWidgets(self):


self.btnDisplay = Button(self,text='1',command=lambda
n=1:self.Display(n))
self.btnDisplay.grid(row=3, column=0, padx=5, pady=5)

self.btnDisplay = Button(self,text='/',command=lambda
n="/":self.Display(n))
self.btnDisplay.grid(row=6, column=3, padx=5, pady=5)

def Display(self, number):
print number

if __name__ == "__main__":
guiFrame = GUIFramework()
guiFrame.mainloop()

self.btnDisplay = Button(self,text='/',command=lambda
n="/":self.Display(n))
self.btnDisplay.grid(row=6, column=3, padx=5, pady=5)

Specify width=1 for both buttons.

self.btnDisplay.grid(row=6, column=3, padx=5, pady=5, width=1)

Add it to the Button widget, not to the grid method.
mybtn = Button(..., width=1)

Thanks,

Please include enough from the post you are answering to make the context
clear for someone who has not received the previous message.

BTW I don't think the `width` argument of the `Button()` call is the best
solution. Take a look at the options of the `grid()` call and figure out
how to tell that the content of the cell should fill it, so that the
Buttons in the grid automatically are equally sized in each row and column.
