Tkinter: How to make a button center itself?
If this can't resolve your problem
button.pack(side=TOP)You'll need to use the method
button.grid(row=1,col=0)the values of row=1,col=0 depend of the position of the other widget in your window
or you can use .place(relx=0.5, rely=0.5, anchor=CENTER)
button.place(relx=0.5, rely=0.5, anchor=CENTER)Example using .place():
from tkinter import * # Use this if use python 3.xx#from Tkinter import * # Use this if use python 2.xxa = Button(text="Center Button")b = Button(text="Top Left Button")c = Button(text="Bottom Right Button")a.place(relx=0.5, rely=0.5, anchor=CENTER)b.place(relx=0.0, rely=0.0, anchor=NW)c.place(relx=1.0, rely=1.0, anchor=SE)mainloop()
