Next, add the following code to the main.qml. Here the call to app.exec () is wrapped inside sys.exit () to return the exit code to the calling process in case of errors, but this isnt strictly necessary. The sky south of the colorful clouds is so blue, and the water falling from the sky is so clear. The app.exec () starts the Qt event loop and launches the application, just as in Qt Widgets.
