Display square Tkinter.Button's?

Question

Why does this code show buttons above their width?

import Tkinter, tkFont
top = Tkinter.Tk()
right = Tkinter.Frame(top)
right.pack(side = "right")
font = tkFont.Font(family="Helvetica", size=60, weight = tkFont.BOLD)

for i in xrange(6):
    b = Tkinter.Button(right, text = str(i), font = font, width = 1, height = 1)
    top.rowconfigure(i, weight = 1)
    top.columnconfigure(i, weight = 1)
    b.grid(row = i/3, column = i%3, sticky = "NWSE")

top.mainloop()

• All buttons are created using width=1, height=1
• For each row and each column rightthere is a call right.rowconfigure(rowi, weight=1)(or columnconfigure).
• Each placement of the grid of each button bis done using sticky NSEW.
• I have installed right.grid_propagate(0)

What exactly am I doing wrong?

If I put the buttons directly on top, the buttons will become wider than the tall ones. They seem to be changing to accommodate the common space. How to prevent this resizing?

Answer 1

a Button , height width, . , . , Frame , (grid_propagate) (columnconfigure rowconfigure).

, .

import Tkinter as tk

master = tk.Tk()

frame = tk.Frame(master, width=40, height=40) #their units in pixels
button1 = tk.Button(frame, text="btn")


frame.grid_propagate(False) #disables resizing of frame
frame.columnconfigure(0, weight=1) #enables button to fill frame
frame.rowconfigure(0,weight=1) #any positive number would do the trick

frame.grid(row=0, column=1) #put frame where the button should be
button1.grid(sticky="wens") #makes the button expand

tk.mainloop()

EDIT: ( ). ;

import Tkinter, tkFont
top = Tkinter.Tk()
right = Tkinter.Frame(top)
right.pack(side = "right")
font = tkFont.Font(family="Helvetica", size=20, weight = tkFont.BOLD)

for i in xrange(6):
    f = Tkinter.Frame(right,width=50,height=50)
    b = Tkinter.Button(f, text = str(i), font = font)

    f.rowconfigure(0, weight = 1)
    f.columnconfigure(0, weight = 1)
    f.grid_propagate(0)

    f.grid(row = i/3, column = i%3)
    b.grid(sticky = "NWSE")

top.mainloop()

- Button, , .

, PhotoImage, image compound "" . :

import Tkinter, tkFont


root = Tkinter.Tk()

font = tkFont.Font(family="Helvetica", size=60, weight = tkFont.BOLD)
blank_image = Tkinter.PhotoImage()

for i in xrange(6):
    b = Tkinter.Button(root, image=blank_image, text=str(i),
                       font=font, compound=Tkinter.CENTER)

    # get the height of the font to use as the square size
    square_size = font.metrics('linespace')
    b.config(width=square_size, height=square_size)

    b.grid(row = i/3, column = i%3, sticky = "NWSE")

root.mainloop()
