Application

The app is the main entry point and container for the Toga GUI.

Usage

The app class is used by instantiating with a name, namespace and callback to a startup delegate which takes 1 argument of the app instance.

To start a UI loop, call app.main_loop()

import toga


def build(app):
    # build UI
    pass


if __name__ == '__main__':
    app = toga.App('First App', 'org.pybee.helloworld', startup=build)
    app.main_loop()

Alternatively, you can subclass App and implement the startup method

import toga


class MyApp(toga.App):
    def startup(self):
        # build UI
        pass


if __name__ == '__main__':
    app = MyApp('First App', 'org.pybee.helloworld', startup=build)
    app.main_loop()
