Designing User Interfaces

All visible parts of the user interface you design in the Web Dynpro View. The View is a structural container for all UI elements that together make up the user interface for a specific step of the business process.

By default, when a Web Dynpro component is created, it includes one standard view. You can add additional views as required.

A view always consists of two parts:

• the view layout

  You position all required UI elements and assign appropriate properties as required. For this, the View Designer tool supplies all necessary functions.

• the view controller

  This is the active program part responsible for controlling the view behavior. All coding concerning view functionality is located here.

To make a view visible on the screen, it must be embedded in a window. One or more views can be embedded in one window. Not all available views must be visible at the same time. To determine, which view is to be replaced by another, and after which user action this replacement takes place, you design navigation between views.
