Chapter 8. HAVi > User Interface Model

8.6. User Interface Model

The user interface model consists of an input model and a display model. The input model includes remote control support and other user inputs. The display model supports graphics and video display functions that are available in typical television-based systems, including support for nonsquare pixels, and graphics plus video overlays.

8.6.1. Input Model

Applications can accept input from a remote control, a keyboard, or a pointing device. Remote control input is provided with classes in the org.havi.ui.event package. The keyboard and pointer device inputs are supported by functions in the java.awt and java.awt.event packages. The org.havi.ui and org.havi.ui.event packages include classes that allow the application to determine the user input capabilities of the platform on which the application is running. A large number of events are optional, allowing manufacturers to customize and add value to their products.
