Extending search and detail screens

Extending the search and detail screens involves the menu and resource item types.

The Applications Manager menu structure contains a hierarchical collection of the following types of items:

Menu – Contains child menu items
Resource – Contains no child menu items, and instead, points to a resource

The menu structure cannot be modified.

Note: You need Net Beans 3.2 IDE to extend search and detail screens in the application.

Each screen is associated with a Form Class and a Java™ Behavior Class. The Form Class is responsible for painting the controls on the screen and the Behavior Class is responsible for populating data in the screen and responding to events that occur in the screen, such as choosing Save.

When navigating to a screen within the Applications Manager, the Form Class of the corresponding screen is loaded and the Behavior Class populates the data in the screen.

Screens are defined in an XML file. This file contains the unique screen ID, Form Class, and Behavior Class for each screen. This file must be extended in order to extract the screens.
