How can I create a scrollable frame in Tkinter using a canvas and scrollbar?

Utilizing Tkinter to Add Scrollbar Functionality to Frames

In Tkinter, creating a scrollable frame necessitates incorporating a scrollbar, which enables the automatic scrolling of content that exceeds the frame's height. Based on insightful discussions, it was suggested that constructing a frame, enclosing a canvas within it, and attaching the scrollbar to the frame would achieve the desired functionality. A window object was then conceived within the canvas to accommodate additional frames.

Using the following Python code, a vertically scrollable frame can be implemented effectively:

import tkinter as tk
import tkinter.ttk as ttk

class VerticalScrolledFrame(ttk.Frame):
    def __init__(self, parent, *args, **kw):
        ttk.Frame.__init__(self, parent, *args, **kw)
        vscrollbar = ttk.Scrollbar(self, orient=VERTICAL)
        vscrollbar.pack(fill=Y, side=RIGHT, expand=FALSE)
        canvas = tk.Canvas(self, bd=0, highlightthickness=0, yscrollcommand=vscrollbar.set)
        canvas.pack(side=LEFT, fill=BOTH, expand=TRUE)
        vscrollbar.config(command=canvas.yview)
        canvas.xview_moveto(0)
        canvas.yview_moveto(0)
        self.interior = interior = ttk.Frame(canvas)
        interior_id = canvas.create_window(0, 0, window=interior, anchor=NW)
        def _configure_interior(event):
            size = (interior.winfo_reqwidth(), interior.winfo_reqheight())
            canvas.config(scrollregion="0 0 %s %s" % size)
            if interior.winfo_reqwidth() != canvas.winfo_width():
                canvas.config(width=interior.winfo_reqwidth())
        interior.bind('<Configure>', _configure_interior)
        def _configure_canvas(event):
            if interior.winfo_reqwidth() != canvas.winfo_width():
                canvas.itemconfigure(interior_id, width=canvas.winfo_width())
        canvas.bind('<Configure>', _configure_canvas)

root = tk.Tk()
frame = VerticalScrolledFrame(root)
frame.pack()
for i in range(10):
    ttk.Button(frame.interior, text="Button " + str(i)).pack()
root.mainloop()

Addressing the Queries:

1. It is possible to achieve this functionality in a more efficient manner by utilizing the code provided.
2. The grid method is preferred because it allows for greater control over the layout of widgets within the frame.
3. The anchor='nw' argument specifies that the window should be anchored to the northwest corner of the canvas, ensuring that the content remains visible as the frame is scrolled vertically.
