尝试在应用程序上放置滚动条

Question

我正在尝试在画布上放置一个滚动条，以滚动其中包含的框架，但是它没有滚动任何内容，有人可以告诉我哪里出了问题？

#  CREATING THE SECTION FOR RESERVATION CONTROL
reservation_control = LabelFrame(main, text='Controle de Reservas', labelanchor='n')


# CREATING THE SCROLLBAR FOR VISUALIZATION

res_scrollbar = Scrollbar(reservation_control)
res_scrollbar.pack(side='left', fill='y')

# CREATING AND USING THE CANVAS FOR THE SCROLLBAR
canvas = Canvas(reservation_control, yscrollcommand= res_scrollbar.set)
res_scrollbar.config(command = canvas.yview)


#  CREATING A FRAME THAT IS AN INTERFACE BETWEEN THE SCROLLBAR CANVAS AND THE LISTS
interface_frame = Frame(canvas)

(...)

#  PACKING THE INTERFACE FRAME
interface_frame.pack(fill='both', expand='true', side='left')

#  PACKING THE CANVAS CONTAINER
canvas.pack(fill='both', expand='true', side='left')

#  PACKING THE RESERVATION CONTROL SECTION
reservation_control.pack(fill='both',expand='true', side='left')
