Scrollbar not stretching to fit the Text widget

I was able to get the Scrollbar to work with a Text widget, but for some reason it isn't stretching to fit the text box.

Does anyone know of any way to change the height of the scrollbar widget or something to that effect?

txt = Text(frame, height=15, width=55)
scr = Scrollbar(frame)
scr.config(command=txt.yview)
txt.config(yscrollcommand=scr.set)
txt.pack(side=LEFT)

In your question you're using pack. pack has options to tell it to grow or shrink in either or both the x and y axis. Vertical scrollbars should normally grow/shrink in the y axis, and horizontal ones in the x axis. Text widgets should usually fill in both directions.

For doing a text widget and scrollbar in a frame you would typically do something like this:

scr.pack(side="right", fill="y", expand=False)
text.pack(side="left", fill="both", expand=True)

The above says the following things:

  • scrollbar is on the right (side="right")
  • scrollbar should stretch to fill any extra space in the y axis (fill="y")
  • the text widget is on the left (side="left")
  • the text widget should stretch to fill any extra space in the x and y axis (fill="both")
  • the text widget will expand to take up all remaining space in the containing frame (expand=True)

Easy solution to use a textbox with an integrated scrollbar:

Python 3:

#Python 3
import tkinter 
import tkinter.scrolledtext

tk = tkinter.Tk() 
text = tkinter.scrolledtext.ScrolledText(tk)
text.pack()
tk.mainloop()

To read the textbox:

string = text.get("1.0","end")   # reads from the beginning to the end

Of course you can shorten the imports if you want.

In Python 2 you import ScrolledText instead.

Here is an example:

from Tkinter import *
root = Tk()
text = Text(root)
text.grid()
scrl = Scrollbar(root, command=text.yview)
text.config(yscrollcommand=scrl.set)
scrl.grid(row=0, column=1, sticky='ns')
root.mainloop()

this makes a text box and the sticky='ns' makes the scrollbar go all the way up and down the window
