Tkinter scrollbar not updating to cover expanded canvas
Question:
I’m having a scrollbar issue with a Tkinter GUI that I’m creating. The GUI contains a class Gen_Box that reproduces a given widget vertically downwards as many times as the widgets add_btn is called. Obviously, this runs off the window frame pretty quickly.
I’ve tried adding a scrollbar to account for this running off the frame. I know these are pretty complicated to add in tkinter and require some hacking around. I referenced this video by Codemy. While I can see the scrollbar to the right of the frame, it doesn’t expand accomodate the added widgets (see screenshots below). I’ve been tinkering around with this all day but am at a loss.
Starting frame:
Frame after second Monitor widget is added:
Also as a note, I’m using CustomTkinter to stylize the widgets.
Current code. Scrollbar is set in the Form.__init__() function. Any help on this issue or other input here is much appreciated.

Try modifying the scrollregion. See the example at https://dafarry.github.io/tkinterbook/canvas.htm which uses event.x and event.y to get the size.
When a new monitor section is added, it is the inner frame (self.inner_frame) get resized, not the canvas (self.canvas). So the <Configure> event should be bound on the inner frame instead of the canvas:
class Form(tk.Frame):
def __init__(self, root):
...
self.canvas.config(yscrollcommand=self.scrollbar.set)
### ----- don't bind on canvas
#self.canvas.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox(ALL)))
self.inner_frame = tk.Frame(self.canvas)
### ----- bind on inner frame instead
self.inner_frame.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox(ALL)))
self.canvas.create_window((0,0), window=self.inner_frame, anchor='nw')
self.load()
...

Try modifying the scrollregion. See the example at https://dafarry.github.io/tkinterbook/canvas.htm which uses event.x and event.y to get the size.
When a new monitor section is added, it is the inner frame (self.inner_frame) get resized, not the canvas (self.canvas). So the <Configure> event should be bound on the inner frame instead of the canvas:
class Form(tk.Frame):
def __init__(self, root):
...
self.canvas.config(yscrollcommand=self.scrollbar.set)
### ----- don't bind on canvas
#self.canvas.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox(ALL)))
self.inner_frame = tk.Frame(self.canvas)
### ----- bind on inner frame instead
self.inner_frame.bind("<Configure>", lambda e: self.canvas.configure(scrollregion=self.canvas.bbox(ALL)))
self.canvas.create_window((0,0), window=self.inner_frame, anchor='nw')
self.load()
...
