to make it simple, I ask a simple question,
I want to make 4 buttons, each (full-fill) stays at one corner of the frame container or tkinter window:
button_1 = tkinter.Button(window, text="Button 1")
button_2 = tkinter.Button(window, text="Button 2")
button_3 = tkinter.Button(window, text="Button 3")
button_4 = tkinter.Button(window, text="Button 4")
button_1.grid(row=0, column=0)
button_2.grid(row=0, column=1)
button_3.grid(row=1, column=0)
button_4.grid(row=1, column=1)
However, they are all tiny buttons that stay together at only the top-left corner of the window, they are not full-filling the entire window as supposed.
