Adding a scrollbar to a grid of widgets in Tkinter
On my project, i want do display my results in a window, using Tkinter as GUI. I place them in a kind of table, using the grid widget, and the window is separated in two different parts (for different results). But after longer runs, the number of results displayed exceed the height of my screen, so i want to add a scrollbar to my program. I already looked into several questions here on stackoverflow, and the answer that has come closest was this:
Adding a scrollbar to a group of widgets in Tkinter
(just to let You know what I am axactly looking for!)
I am not able to apply that to my program though, maybe because I am rather new to Python and sometimes think i am a Dr. Frankenstein with tutorial-examples.
I tried a lot now, but i cant get the tables to be displayed in the canvas, possibly just some little thing i am missing.
I created an abstract example of my program (without scrollbar) so You know what I am working with, maybe someone of You can help my getting that scrollbar where it belongs!
Thank You very much!
example code: (runs)
import Tkinter as tk
toprow=1
botrow=1
class ProgramWindow(tk.Frame):
def __init__(self,name):
self.name = name
tk.Frame.__init__(self,root)
self.pack()
if name=="BotWin":
tk.Label(self,text="FirstColBot",width=30).grid(row=0,column=0)
tk.Label(self,text="SecndColBot",width=20).grid(row=0,column=1)
elif name=="TopWin":
tk.Label(self,text="FirstColTop",width=30).grid(row=0,column=0)
tk.Label(self,text="SecndColTop",width=20).grid(row=0,column=1)

additional code with my tries to add the scrollbar (based on example shown in link above).
if the scrollbar is only shown in the lower part, that would be okay since thats the part with the many results.)

toprow=1
botrow=1

tk.Label(self,text="SecndColBot",width=20).grid(row=0,column=1)
self.canvas = tk.Canvas(root, borderwidth=0, background="#ffffff")
self.vsb = tk.Scrollbar(root, orient="vertical", command=self.canvas.yview)
self.canvas.configure(yscrollcommand=self.vsb.set)
self.vsb.pack(side="right", fill="y")
self.canvas.pack(side="left", fill="both", expand=True)
self.canvas.create_window((4,4), window=self.frame)
self.bind("<Configure>", self.OnFrameConfigure)
elif name=="TopWin":
self.pack()

To adapt Bryan Oakley’s answer to your specific problem:
scrollregionNote: when subclassing in python, you do not need to store the result of parent
__init__since it operate on self.Here is the patch:
