Kivy Tutorial for Beginners: Part 5 – Editing Button Properties in Your Python Applications

Buttons are a common element in GUI applications, and in this tutorial, we will learn how to customize the properties of buttons in Kivy using Python. By changing the appearance and behavior of buttons, we can create interactive and visually appealing user interfaces.

Step 1: Creating a Button

First, let’s create a simple button in our Python application:

        from kivy.app import App
        from kivy.uix.button import Button

        class MyApp(App):
            def build(self):
                return Button(text='Click me!')
        
        if __name__ == '__main__':
            MyApp().run()
    

By running this code, you will see a button with the text “Click me!” displayed on the screen.

Step 2: Customizing Button Properties

Now, let’s customize the properties of our button, such as changing the text color, background color, font size, and adding an action when the button is clicked:

        from kivy.app import App
        from kivy.uix.button import Button

        class MyApp(App):
            def build(self):
                button = Button(text='Click me!', color=(1, 0, 0, 1), background_color=(0, 1, 0, 1), font_size=30)
                button.bind(on_press=self.on_button_click)
                return button

            def on_button_click(self, instance):
                print('Button clicked!')
        
        if __name__ == '__main__':
            MyApp().run()
    

Now, when you run the code, you will see a button with red text, green background, and a font size of 30. Additionally, when you click the button, the message “Button clicked!” will be printed to the console.

Conclusion

By customizing the properties of buttons in Kivy using Python, we can create visually appealing and interactive user interfaces for our applications. Experiment with different properties and see what works best for your project!
