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.
In this article we will learn how we can add a button with the Text input in kivy, just like the same we have in the input and submit button. Before proceeding to that you must know about Textinput widget and Button in kivy.
TextInput: The TextInput widget provides a box for editable plain text. Unicode, multiline, cursor navigation, selection and clipboard features are supported.
Button: The Button is a Label with associated actions that are triggered when the button is pressed (or released after a click/touch). We can add functions behind the button and style the button.
To work with Textinput and buttons you have to import it by the command –
from kivy.uix.textinput import TextInput from kivy.uix.button import Button
Basic Approach: 1) import kivy 2) import kivyApp 3) import Button 4) import Boxlayout 5) import Textinput 6) import BoxLayout 7) Set minimum version(optional) 8) create App class 9) return Layout/widget/Class(according to requirement) 10) Run an instance of the class
Implementation of the Approach –
main.py file
## Sample Python application demonstrating that ## how to create Text Input with Button in kivy # 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 kivy.app import App # this restrict the kivy version i.e # below this kivy version you cannot # use the app or software kivy.require('1.9.1') # creates the button in kivy # if not imported shows the error from kivy.uix.button import Button # The TextInput widget provides a # box for editable plain text from kivy.uix.textinput import TextInput # BoxLayout arranges widgets in either # in vertical fashion that # is one on top of another or in # horizontal fashion that is one after another. from kivy.uix.boxlayout import BoxLayout # to change the kivy default settings we use this module config from kivy.config import Config # 0 being off 1 being on as in true / false # you can use 0 or 1 && True or False Config.set('graphics', 'resizable', True) # Create the App class class BTNTEXTApp(App): # defining build() def build(self): # Telling orientation b = BoxLayout(orientation ='vertical', ) # Adding the text input t = TextInput(font_size = 30, size_hint_y = None, height = 100) # Adding Button and styling f = Button(text ="Push Me !", font_size ="20sp", background_color =(.67, 1, .33, 1), color =(1, 1, 1, 1) ) b.add_widget(t) b.add_widget(f) return b # Run the App if __name__ == "__main__": BTNTEXTApp().run() |
