SimpleEventHandlingRecipe
This builds upon HelloWorldRecipe, adding a button to close the app:
import PicoGUI # for PG_APP_TOOLBAR you'd use PicoGUI.ToolbarApp() app = PicoGUI.Application('Greetings') l = app.addWidget('Label') l.side = 'All' l.text = 'Hello, World!' l.font = ':24:Bold' bye = app.addWidget('Button') bye.text = 'Yeah, all right, now go away' def closeapp(ev, button): app.send(app, 'stop') app.link(closeapp, bye, "activate") app.run()
