🔒 Help with creating a scrollable frame in Tkinter

[sweet vapor]

class ScrollingFrame:

    def __init__(self, root:Frame):

        #outer placeholder frame for canvas and scrollbar
        self.sf_outer_frame = Frame(master=root, background='pink');
        self.sf_outer_frame.columnconfigure(index=0, weight=1)
        self.sf_outer_frame.columnconfigure(index=1, weight=0)
        self.sf_outer_frame.rowconfigure(index=0, weight=1)

        self.sf_canvas = Canvas(master=self.sf_outer_frame, background='purple');
        self.sf_canvas.grid(row=0, column=0, sticky='nsew', padx=10, pady=10)        

        self.sf_scroller = Scrollbar(master=self.sf_outer_frame, orient='vertical', command=self.sf_canvas.yview);
        self.sf_canvas.config(yscrollcommand=self.sf_scroller.set)
        self.sf_scroller.grid(row=0, column=1, sticky='ns')

        self.sf_inner_frame = Frame(master=self.sf_canvas, background='orange');
        self.sf_canvas.create_window((0, 0), window=self.sf_inner_frame, anchor='nw')
        self.sf_inner_frame.bind('<Configure>', lambda event:self.sf_canvas.configure(scrollregion=self.sf_canvas.bbox('all')))
    
    def get_handle_frame(self):
        return self.sf_outer_frame```

this is how far i've gotten. I can see that the canvas and the scroll bar are being created but for some reason the inner frame isn't showing! help would be appreciated :)

• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.
