How to fit Tkinter listbox to contents

Question

I'm adding strings to a listbox using the code below. When I run the code and the window opens, the longer strings get clipped as the window is not large enough (see screenshot). I have tried making the window resizeable and adding scroll bars but I was wondering if there was a way to automatically size it to fit the content.

master = tk.Tk()
listbox = tk.Listbox(master, selectmode=tk.SINGLE)

games = ["Garry's Mod", "Mount and Blade: Warband", "Tekkit"]
for game in sorted(games):
    listbox.insert(tk.END, game)

button = tk.Button(master, text="Execute", command=execute)

listbox.pack()
button.pack()
tk.mainloop()

Answer 1

Resetting the listbox width worked for me. I used the Oblivion's answer and noticed that the width is always zero.

listbox = tk.Listbox(master, selectmode=tk.SINGLE)
listbox.config(width=0)

I also recommend to reset the root window geometry after reloading a content of the list. Otherwise if user manually extends a window the window would stop accommodate size of its content.

root.winfo_toplevel().wm_geometry("")
