Mysterious extra space after buttons in tkinter

Question

I'm running tkinter on Python3.4 on Windows and I want two buttons in my GUI box. I'm following [this link]

The code is this:

import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.initialize()

    def initialize(self):
        button_crop = tk.Button(self, text=u"Crop", command=self.OnCrop)
        button_crop.pack(side="left")

        button_reset = tk.Button(self, text=u"Reset", command=self.OnReset)
        button_reset.pack(side="left")

    def OnCrop(self):
        pass

    def OnReset(self):
        pass

app = App()

app.mainloop()

Now I get a button which has some extra space to the right

I've tried initialising a grid() and then button_crop.grid(column=0, row=1) but I get the same result.

Please help me remove this extra blank space to the right.

Try to remove min and max buttons. It seems that form cannot be less than size of system buttons. Look here https://stackoverflow.com/questions/2969870/removing-minimize-maximize-buttons-in-tkinter — ventik, Jul 10 '17 at 06:04
@ventik That is not desirable.. I'm ok with increasing the size of the buttons to fit the minimum width. — Anjali, Jul 10 '17 at 06:21
Do you want the buttons to grow to fill the space, or the window to shrink to remove the extra space? — Bryan Oakley, Jul 10 '17 at 12:15

Do you want this behaviour?

import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.initialize()

    def initialize(self):        

        button_crop = tk.Button(self, text=u"Crop", command=self.OnCrop)
        button_crop.grid(row=0, column=0, sticky=(tk.N, tk.S, tk.E, tk.W))

        button_crop = tk.Button(self, text=u"Reset", command=self.OnReset)
        button_crop.grid(row=0, column=1, sticky=(tk.N, tk.S, tk.E, tk.W))

        for i in range(2):
            self.columnconfigure(i, weight=1)

        self.rowconfigure(0, weight=1)

    def OnCrop(self):
        pass

    def OnReset(self):
        pass

app = App()

app.mainloop()

Can I not just extend size of the "crop" and "reset" buttons till they both just add up to the minimum width? – Anjali Jul 10 '17 at 06:20
Yes, this is great! Could you explain what changes in your code helped me get this behaviour? Thanks a ton. – Anjali Jul 10 '17 at 06:47

columnconfigure sets options for some column, weight=1 means that this column will be stretchable. read more here http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/grid-config.html – ventik Jul 10 '17 at 06:50
