  • Basic Concepts

    View : A view is a visible screen area and contains screen elements. Example a text field for entering Employee Name

    Controller: Every view has a dedicated view controller and every component has a component controller. View controller performs event handling based on actions triggered in a view.

    Window: A window contains one or more views. For a view to be displayed in the browser at run time, it has to be embedded in the window. Windows have inbound and outbound plugs and a window controller which is global and visible to all controllers with in a component.

    Component: A component contains all components like views, controllers, windows etc.. required to execute a WD application and acts as an application entry point. Components interact with each other via component interfaces.

    Application: Application is identified by a URL and is something executable for the user. When the user invokes the URL, WD creates an instance of the applications root component i.e. starting the root component and navigating to initial view which in turn is displayed in an initial window.

    Context: It is repository of data and like a data container. Data used in views or component are stored in context.

    Controllers: These are active parts in Web DynPro component. Component Controller and Interface controller are basically responsible for generating data which will be supplied to View Controller for display. Data that can be accessed by controller are defined in corresponding context.

    Plugs : They can be divided into Inbound plugs and Outbound plugs. Plugs are used for navigation between different views. To navigate from one view to the other, outbound plug of the calling view should be linked with the inbound plug of the called view. When a view is entered via an inbound plug, it triggers the event handler method and thus an event handler method is generated for every inbound plug.
