A scrollbar can be used with various widgets such as Listbox, Text, Canvas, and Entry.
Work Step by Step
In Tkinter, a scrollbar can be attached to a widget by using the "yscrollcommand" or "xscrollcommand" option, which takes a function that will be called every time the scrollbar is changed. The widget can then be made scrollable by configuring the scrollbar to modify the view of the widget.
