In this article, we will learn how to disable a button in kivy, there are some places where we need to disable the buttons So in this article you will learn how to do that.
Kivy Tutorial – Learn Kivy with Examples.
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.But to disable the button we have a property name :
disabled that must be true
this property will help in disabling the button i.e. button will be there but is of no use as it is disabled no functionality of button will work.
Note: disabled property was introduced in version 1.8.0. If you want to use it you need to actualize your framework.
Basic Approach to follow while creating and disabling button : -> import kivy -> import kivy App -> import button -> set minimum version(optional) -> Extend the class -> Add and return a button -> Add disabled = true to disable button -> Run an instance of the class
Firstly, let’s see how to create a fully working button and then see how to disable it and its functionality.
Code #1: How to create fully working button
def build(self):
    # use a (r, g, b, a) tuple
    btn = Button(text ="Push Me !",
                 font_size ="20sp",
                 background_color =(1, 1, 1, 1),
                 color =(1, 1, 1, 1),
                 size =(32, 32),
                 size_hint =(.2, .2),
                 pos =(300, 250))
  
    return btn

                    
Output:   Code #2: How to disable the button
def build(self):
        # use a (r, g, b, a) tuple
        btn = Button(text ="Push Me !",
                     font_size ="20sp",
                     background_color =(1, 4, 6, 1),
                     color =(1, 1, 1, 1),
                     size =(32, 32),
                     size_hint =(.2, .2),
                     pos =(300, 250),
  
                     # Disabling the button   
                     disabled = True
  
                     )

                    
Output:   Code #3: Both disable and working button together
# import kivy module 
import kivy 
    
# this restrict the kivy version i.e 
# below this kivy version you cannot 
# use the app or software 
kivy.require("1.9.1"
    
# base Class of your App inherits from the App class. 
# app:always refers to the instance of your application 
from kivy.app import App 
    
# creates the button in kivy 
# if not imported shows the error 
from kivy.uix.button import Button 
  
# This layout allows you to set relative coordinates for children. 
from kivy.uix.relativelayout import RelativeLayout 
  
# class in which we are creating the button 
class ButtonApp(App): 
        
    def build(self):
  
        r1 = RelativeLayout()
  
          
        # working button
        btn1 = Button(text ="Push Me !"
                   font_size ="20sp"
                   background_color =(1, 1, 1, 1), 
                   color =(1, 1, 1, 1), 
                   size =(32, 32), 
                   size_hint =(.2, .2), 
                   pos =(200, 250)) 
  
        # disabled button
        btn2 = Button(text ="Disabled:(:( !"
                   font_size ="20sp"
                   background_color =(1, 1, 1, 1), 
                   color =(1, 1, 1, 1), 
                   size =(32, 32), 
                   size_hint =(.2, .2), 
                   pos =(500, 250),
  
                   # Add disabled property true to disabled button
                   disabled = True)
  
        r1.add_widget(btn1)
        r1.add_widget(btn2)
         
        # bind() use to bind the button to function callback 
        btn1.bind(on_press = self.callback)
        return r1 
    
    # callback function tells when button pressed 
    def callback(self, event): 
        print("button pressed"
        print('Yoooo !!!!!!!!!!!'
            
    
# creating the object root for ButtonApp() class  
root = ButtonApp() 
  
# run function runs the whole program 
# i.e run() method which calls the target 
# function passed to the constructor. 
root.run()
