Web Dynpro Window 

The previously described simple application example contained a Web Dynpro component with one view only. In the tutorial of this documentation, the instructions include from the beginning the creation of applications with two views which are connected via navigation. This and the following chapter describe the communication between the different views of a component.

Each Web Dynpro component contains at least one Web Dynpro window. All views that are to be displayed when using a Web application are embedded in this window. The window is processed in the Window Editors of the ABAP Workbench. The required navigation between the individual views can be set up in the window (see Navigation).

 

The Web Dynpro window contains the structure of all views to be displayed and is also connected to the Web Dynpro application via an interface view (see also below).

Advanced Functions of Web Dynpro Windows

Window Controller and Window Plugs

Each Web Dynpro window contains a controller with context, methods, Outbound and Inbound Plugs. You can use the plugs to set up cross-component navigation.

In a simple application, the starting point of a navigation is the start view. It is created at design time. This is done in the Window Editor using the context menu of the window tree. In a more complex application, the event handler method of the used inbound plug can be used to dynamically decide which view is to be displayed first.

For more information about window plugs see the following documents and also Navigation Using Window Plugs in section Cross-Component Programming and in the Architecture manual under Window Plugs.

 

Inbound plugs and outbound plugs of a window are copied to the corresponding interface view when the interface flag is set. The event handler is implemented in the window itself.

Interface View

An interface view with an identical name is automatically created for each window. It defines the Cross-component Interface of the Window. Inbound plugs and outbound plugs of a window are copied to the corresponding interface view when the interface flag is set. Event handlers are implemented in the window itself. Plugs of an interface view can be used for cross-component navigation, inbound plugs of an interface view can be used for the connection to the Web Dynpro application.
