Tkinter columnconfigure weight not adjusting
columnconfigure() or rowconfigure() functions are applied to the window or frame, of which the widget is a part of. Here you are applying it on the button itself. Apply it on on its parent basically.
Here is a small example.
import tkinter as tkapp = tk.Tk()bttn1 = tk.Button(app, text="I do nothing")bttn2 = tk.Button(app, text='Me too!')bttn3 = tk.Button(app, text='Same here!')bttnCt = tk.Button(app, text='Total Clicks: 0')bttn1.grid(row=0, column=0, sticky="ew")bttn2.grid(row=0, column=1, sticky="ew")bttn3.grid(row=0, column=2, sticky="ew")bttnCt.grid(row=1, column=1, sticky="ew")bttn_list = [bttn1, bttn2, bttn3, bttnCt]for i in range(len(bttn_list)): app.columnconfigure(i, weight=1) ## Not the button, but the parentapp.mainloop()
