In this Kivy Python article we want to learn How to Build Button in Kivy Python, Kivy is an open source Python framework and that is used for building user interfaces. it allows developers to build crossplatform applications that can run on desktop and mobile devices. in this article we want to learn about building a button in Kivy using Python.
How to Build Button in Kivy Python
So first of all we need to install Python Kivy and we can use pip for the installation
|
1 |
pip install kivy |
After that you have installed Kivy, you need to import the necessary modules to create button. the main module you need is the App module, which is the base class for creating Kivy applications. you also need the Button module for creating a button.
|
1 2 3 |
import kivy from kivy.app import App from kivy.uix.button import Button |
Next, you need to create App class, which is the main class for your Kivy application. you can do this by subclassing the App class and defining build() method.
|
1 2 3 |
class MyApp(App): def build(self): return Button(text='GeeksCoders') |
In the build() method, we have created a Button object and set its text property. build() method must return root widget of your application, which in this case is the Button object.
And finally we need to run our Kivy application. for this we need to create an instance of MyApp class and call its run() method.
|
1 2 |
if __name__ == '__main__': MyApp().run() |
if name == ‘main’ statement checks if the current code is being run as the main program. if it is, it creates an instance of the MyApp class and calls its run() method.
This is the complete code for this article
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
# Import Kivy modules from kivy.app import App from kivy.uix.button import Button # Create the App class class MyApp(App): # Define build() method def build(self): # Create Button object with text return Button(text='GeeksCoders') # Run the application if __name__ == '__main__': MyApp().run() |
Run the complete code and this will be the result
In result we can say that building a button in Kivy is an easy process. you need to install Kivy, import the necessary modules, create the App class, and define build() method to create Button object.
