This project is at proof of concept stage and is not feature complete. Please do not use it in production.

Dependencies

• rubicon-objc
• pydispatcher

Installation

The latest version is available for installation in PyPI:

pip install applepy-ui

Usage

class Sample(App):
    def body(self) -> Scene:
        with Window(title='Applepy example', size=Size(640, 100)) as w:
            with VerticalStack():
                with HorizontalStack():
                    Label(text='Hello')
                    Label(text='World')
                
            return w.center()
Sample().run()

It also works on mobile:

class MobileSample(App):
    def body(self):
        with SimpleScreen() as s:
            with HorizontalStack():
                with VerticalStack():
                    Label(text='Hello World')
            return s

def main():
    sys.exit(MobileSample().run())

Events can be handled synchronously and asynchronously in the same context:

class AsyncSample(App):
    def clicked(self) -> None:
        time.sleep(2)
        Alert.show_info(informative_text='Hello', message_text='Synchronous World')

    async def clicked_async(self) -> None:
        await asyncio.sleep(2)
        Alert.show_info(informative_text='Hello', message_text='Asynchronous World')

    def body(self) -> Scene:
        with Window(title='Applepy async example', size=Size(640,480)) as w:
            with HorizontalStack():
                with VerticalStack():
                    Button(title='Sync action', action=self.clicked)
                    Button(title='Async action', action=self.clicked_async)
                return w.center()

AsyncSample().run_async()
