Tkinter Text box widget is used to insert multi-line text. This widget can be used for messaging, displaying information, and many other tasks. The important task is to get the inserted text for further processing. For this, we have to use the get() method for the textbox widget.
Syntax: get(start, [end])
where,
start is starting index of required text in TextBox
end is ending index of required text in TextBox
If end is not provided, only character at provided start index will be retrieved.
Approach:
- Create Tkinter window
- Create a TextBox widget
- Create a Button widget
- Create a function that will return text from textbox using get() method after hitting a button
Below is the implementation:
Python3
import tkinter as tk  # Top level windowframe = tk.Tk()frame.title("TextBox Input")frame.geometry('400x200')# Function for getting Input# from textbox and printing it # at label widget  def printInput():    inp = inputtxt.get(1.0, "end-1c")    lbl.config(text = "Provided Input: "+inp)  # TextBox Creationinputtxt = tk.Text(frame,                   height = 5,                   width = 20)  inputtxt.pack()  # Button CreationprintButton = tk.Button(frame,                        text = "Print",                         command = printInput)printButton.pack()  # Label Creationlbl = tk.Label(frame, text = "")lbl.pack()frame.mainloop() |
Output:
Snapshot after pressing Print button for above code
