Advanced UI Customization

The basic customizations in the previous sections require little or no custom code. If these options do not provide a solution, you can replace portal components with custom versions. The advanced customizations below require Java or C# coding. For an introduction to the inner workings of the portal UI, see Chapter 11, "Portal UI Architecture"

This section contains the following chapters:

• Chapter 12, "Using PEIs": Portal Event Interfaces (PEIs) are used to execute custom actions in many places throughout the portal. For example, you can modify search queries before they are processed, or perform validation when users attempt to create new portal objects.

• Chapter 13, "Using View Replacement": You can completely customize the display of portal components by creating a custom version of the associated View class(es).

• Chapter 14, "Creating Custom Activity Spaces": Activity Spaces group task-specific actions into logical sets to provide portal developers with base functionality, and combine related pages to create cohesive Model-View-Control (MVC) objects. Everything in the portal is an Activity Space: a MyPage, an administrative editor, even the Directory tree. A custom Activity Space allows you to add new pages to your portal.

• Oracle WebCenter Interaction includes a collection of useful tools and components to support UI customization. For details, see Chapter 15, "Accessing Portal Objects", Chapter 16, "Adding Custom Images", and Chapter 17, "Using VarPacks (Variable Packages)"
