Scrollable canvas off-screen in tkinter
Update: I ended up switching to using Treeview for this as it supports scrollbar and it displays my table much cleaner.
I have an app that inputs labels from a file to build a 'table'. I wanted to add a scrollbar but have had some difficulty doing so. I got it working somewhat but it wasn't oriented properly and you could only see half the table. I added the .grid to stretch the frame but now when I draw the table, it extends off the screen and the scrollbar is just drawn on the side of the widget- it doesn't scroll anywhere.
Here's the portion of the class that draws the table:
def tabledraw(self):
self.table_values = Canvas(window1, borderwidth=5)
#self.table_values.configure(scrollregion=[0,0,970,600])
self.frame = Frame(self.table_values)
self.vsb = Scrollbar(window1, orient="vertical", command=self.table_values.yview)
self.table_values.configure(yscrollcommand=self.vsb.set)
self.vsb.grid(row=3, column=2, sticky=N+S+E)
self.table_values.grid(row=3, columnspan=3, padx=20, pady=20)
self.table_values.create_window((4,4), window=self.frame, anchor="nw", tags="self.frame")
self.frame.grid(columnspan=3, sticky=E+W)
self.frame.bind("<Configure>", self.onFrameConfigure)
with open('table_co.pkl', 'rb') as infile:
table = pickle.load(infile)
for i in range(self.height):
for j in range(self.width):
self.b = Entry(self.frame, text="", width=30)
self.b.grid(row=i, column=j)
self.b.insert(0, str(table[i][j]))
def onFrameConfigure(self, event):
#self.table_values.config(scrollregion=[0,0,970,200])
self.table_values.configure(scrollregion=self.table_values.bbox("all"))
I tried assigning a static value to the canvas' scrollable region but it seems to have made no change.
I'm new to python so if I'm doing something wrong, let me know.

This code does not run. In order for us to test your code we need to be able to run it. Please provide a Minimal, Complete, and Verifiable example. That includes providing the data you use; We have no access to thetable_co.pklfile.
