python - How to get the content of a tkinter Text object

Question

I'm trying to use tkinter.Text to create a text area in Python. With that, I want to get all the input they put into that text area and display it in the Entry field above it. It gives an error saying it needs two arguments.

from Tkinter import *

def create_index():
        var = body.get(0)
        link.insert(10,var)
        file.close()

master = Tk()
Label(master, text="Link:").grid(row=0)
Label(master, text="Body:").grid(row=1)

link = Entry(master)
body = Text(master)

link.grid(row=0, column=1)
body.grid(row=1, column=1)
Button(master, text='Show', command=create_index).grid(row=3, column=1, sticky=W, pady=4)

mainloop()

To get all the input from a tkinter.Text, you should use the method get from the tkinter.Text object you are using to represent the text area. In your case, body should be the variable of type tkinter.Text, so here's an example:

text = body.get("1.0", "end-1c")  

tkinter.Text objects count their content as rows and columns. The "1.0" indicates exactly that: you want to get the content starting from line 1 and character 0 (this is the default starting point of a tkinter.Text object).

Here's a complete working example, where basically on the click of a button, the method get_text is called and adds the content of body to an tkinter.Entry object that I called entry (through the use of a variable of type tkinter.StringVar. See documentation for more information):

import tkinter

def get_text():
    content = body.get(1.0, "end-1c")
    entry_content.set(content)

master = tkinter.Tk()

body = tkinter.Text(master)
body.pack()

entry_content = tkinter.StringVar()
entry = tkinter.Entry(master, textvariable=entry_content)
entry.pack()

button = tkinter.Button(master, text="Get tkinter.Text content", command=get_text)
button.pack()

master.mainloop()
