Scrollbar in tkinter not showing up

I'm learning how to do GUI in python, I am trying to make a scrollbar for my listbox but it's not showing up. I tried many different things with the same results, so to make sure that I am not doing something wrong I went to the example in

The code for the example is:

from tkinter import *

root = Tk()
root.geometry("150x200")

w = Label(root, text ='GeeksForGeeks',
          font = "50")

w.pack()

scroll_bar = Scrollbar(root)

scroll_bar.pack( side = RIGHT,
                fill = Y )

mylist = Listbox(root,
                 yscrollcommand = scroll_bar.set )

for line in range(1, 26):
    mylist.insert(END, "Geeks "   str(line))

mylist.pack( side = LEFT, fill = BOTH )

scroll_bar.config( command = mylist.yview )

root.mainloop()

CodePudding user response：

Because of the size of the window, the listbox is too small to have a scrollbar. Decrease the size of the window by adding root.geometry("50x50") before the root.mainloop().

CodePudding user response：

I use to face a similar problem. It can be fixed by defining the scrollbar and packing it before packing the listbox.

Here is the final code:

from tkinter import *

root = Tk()
root.geometry("150x200")

w = Label(root, text ='GeeksForGeeks',
          font = "50")

w.pack()

mylist = Listbox(root)

scroll_bar = Scrollbar(root, command=mylist.yview, orient=VERTICAL)

scroll_bar.pack( side = RIGHT,
                fill = Y )

for line in range(1, 26):
    mylist.insert(END, "Geeks "   str(line))

mylist.pack( side = LEFT, fill = BOTH )

mylist.config( yscrollcommand = scroll_bar.set )

root.mainloop()

Thank You!
