Answer
To associate a scrollbar with a view in Tkinter, you need to use the set method of the scrollbar and pass it the values of the view you want it to control.
Work Step by Step
For example, if you have a canvas widget named canvas and a scrollbar widget named scrollbar, you can associate the scrollbar with the canvas like this:
scrollbar.config(command=canvas.yview)
canvas.config(yscrollcommand=scrollbar.set)
In this example, the command option of the scrollbar is set to the yview method of the canvas, and the yscrollcommand option of the canvas is set to the set method of the scrollbar. This sets up a bidirectional relationship between the canvas and the scrollbar, so that when the scrollbar is used to scroll the canvas, the canvas will automatically update the position of the scrollbar, and vice versa.
