Architecture of NewtApp
Application Layer
This layer handles application-wide things, such as:
- Registration/Unregistration
- For various system services such as find and soup change notification.
- Application state
- Applications on the Newton should save their state on close and restore that state on open. This way, an opened application looks as it did when it was last closed.
- User preferences
- The application layer handles preferences and is responsible for getting and maintaining relevant user information.
- About Slip
- Where programmers indulge their egos, as well as provide version and copyright information.
- Switching between views
- This handles the overview button to switch between overview and detail layouts.
