Python | TextInput in kivy using .kv file

  • Last Updated : 07 Feb, 2020

Kivy is a platform independent GUI tool in Python. As it can be run on Android, IOS, linux and Windows etc. It is basically used to develop the Android application, but it does not mean that it can not be used on Desktops applications.

👉🏽 Kivy Tutorial – Learn Kivy with Examples.


The TextInput widget provides a box for editable plain text. Unicode, multiline, cursor navigation, selection and clipboard features are supported.

The TextInput uses two different coordinate systems:

  • (x, y) – coordinates in pixels, mostly used for rendering on screen.
  • (row, col) – cursor index in characters / lines, used for selection and cursor movement.
Basic Approach:

1) import kivy
2) import kivyApp
3) import widger
4) import Relativelayout
5) import textinput
6) Set minimum version(optional)
7) Create Widget class
8) Create App class
9) create .kv file (name same as the app class):
        1) create textinput
10) return Layout/widget/Class(according to requirement)
11) Run an instance of the class

Implementation of the Approach

# file

# Program to Show how to use textinput 
# (UX widget) in kivy using .kv file
# import kivy module    
import kivy  
# base Class of your App inherits from the App class.    
# app:always refers to the instance of your application   
from import App 
# this restrict the kivy version i.e  
# below this kivy version you cannot  
# use the app or software  
# Widgets are elements
# of a graphical user interface
# that form part of the User Experience.
from kivy.uix.widget import Widget
# The TextInput widget provides a
# box for editable plain text
from kivy.uix.textinput import TextInput
# This layout allows you to set relative coordinates for children. 
from kivy.uix.relativelayout import RelativeLayout
# Create the widget class
class textinp(Widget):
# Create the app class
class MainApp(App):
    # Building text input
    def build(self):
        return textinp()
    # Arranging that what you write will be shown to you
    # in IDLE
    def process(self):
        text = self.root.ids.input.text
# Run the App
if __name__ == "__main__":

# main.kv file

# .kv file implementation of the code
    title: 'InputDialog'
    auto_dismiss: False
    id: test1
    # Using relative layout to arrange properly
        orientation: 'vertical'
        pos: self.pos
        size: root.size
        id: test2
        # Defining text input in .kv
        # And giving it the look . pos and features
            id: input
            hint_text:'Enter text'
            pos_hint: {'center_x': 0.5, 'center_y': 0.705}
            size_hint: 0.95, 0.5
            on_text: app.process()


When you run the App you will see:

After some input you will see:
