How to exit a Kivy application using a button ?
Kivy is a graphical user interface open-source Python library that allows you to develop multi-platform applications on Windows, macOS, Android, iOS, Linux, and Raspberry-Pi. In addition to the regular mouse and keyboard inputs, it also supports multitouch events. The applications made using Kivy will similar across all the platforms, but it also means that the application’s feel or look will differ from any native application.
In this article, we will develop a GUI window using kivy framework of python, and we will add a single button on the window which will close kivy application on click
Approach:
- Import kivy button
- Import kivy app
- Import kivy builder
- Create App class
- Return builder string
- Run an instance of the class
Below is the implementation.
Python3
# importing button widget from kivy framework from kivy.uix.button import Button from kivy.app import App from kivy.core.window import Window # importing builder from kivy from kivy.lang import Builder # this is the main class which # will render the whole application class uiApp(App): # method which will render our application def close_application( self ): # closing application App.get_running_app().stop() # removing window Window.close() def build( self ): return Builder.load_string( """ #:import C kivy.utils.get_color_from_hex Button: # text which will appear on first button text:"Close App" on_release: app.close_application() """ ) # running the application uiApp().run() |
