Relief, sunken and raised appearance of widgets
We can control the appearance of our Spinbox widgets by using a property that makes them appear in different sunken or raised formats.
Getting ready
We will add one more Spinbox control to demonstrate the available appearances of widgets, using the relief property of the Spinbox control.
How to do it…

# Adding a second Spinbox widget
spin = Spinbox(mighty, values=(0, 50, 100), width=5, bd=20,
command=_spin)
spin.grid(column=1, row=2)This will create the following GUI output:
GUI_spinbox_two_sunken.py

In our code, we did not specify which relief property to use, so the relief defaulted to tk.SUNKEN.

We imported tkinter as tk. This is why we can call...
