ABAP 7.4 - Chapter 16 - User Interfaces (Web Dynpro)

Navigation between different views is enabled by: Plugs. Properties. Nodes. Windows.

For all controllers, methods exist that are called by the Web Dynpro framework in a predefined order. These are called. hook methods. standard methods. wd methods. default methods.

Different hook methods are available depending on the controller type. All controller types contain at least two hook methods. These methods are processed only once during the lifetime of a controller instance: when a controller instance is created. when a controller instance is deleted.

You can link a UI element of the user interface of the view with an element of the view context. This is known as: data binding. context mapping.

You can define a mapping between two global controller contexts or from a view context to a global controller context. This is known as: data binding. context mapping.

Each component has an interface; of what does this interface consist? Select all that apply (There are two correct answers). Interface view. Interface context. Interface controller.

What is a plug? Select all that apply (There are four correct answers). Can be defined as inbound, outbound, or both. Forms the basis of navigation within a Web Dynpro. Can be defined as default inbound. Can be defined as a startup. Can be defined as an exit. Can be assigned to multiple views. Can be defined as outbound controlling multiple inbound plugs. Can be defined as inbound and be controlled by multiple outbound plugs.

What does a Web Dynpro component contain? Select all that apply. (There are three correct answers). Multiple views within a window. UI elements. Component controller. A context. Exactly one interface controller.

What does a view do? Select all that apply (There are four correct answers). Contains other views. Can be contained in a window. Contains windows. If entered by an inbound plug, can cause an event handler method to be called. Contains a view controller.

Identify the types of controller. Select all that apply (There are five correct answers). Component controller. Custom controller. Consumer controller. Configuration controller. View controller. Window controller.

Identify the types of layout managers. Select all that apply (There are four correct answers). FlowLayout. RowLayout. ColumnLayout. MatrixLayout. GridLayout. TreeLayout.

The binding between a UI element and a context attribute is a two-way relationship. True. False.

Identify the ways to map context structures. Select all that apply. (There are two correct answers). Direct context mapping. External context mapping. Dynamic context mapping.

What is the Web Dynpro programming model is based on?. Classic Dynpro programming. Business Server Pages (BSPs). Model View Controller (MVC). Internet Transaction Server (ITS).

When does the lifetime of a Web Dynpro component begin and end?. It begins when instantiated and it ends when the program ends or the object is freed. It begins the first time it is called at runtime, and it ends with the Web Dynpro application that called and instantiated the component ends. It begins each time it is called, and it ends when the component completes.

When does the lifetime of a component controller begin and end?. It begins with the Web Dynpro component and ends with the Web Dynpro application that called it. It begins the first time the Web Dynpro application is called at runtime and ends when the Web Dynpro application that called and instantiated the component ends. It lasts from creating data within the controller to cover the whole period during which the component is in use.

In addition to the visible part (the layout), a view also contains a controller and a context. True. False.

A view can only be displayed in which circumstances?. It has been embedded in a window. It contains an inbound and outbound plug. It can always be displayed.

What can be exposed in the component interface of a Web dynpro component?. Standard hook methods of the component controller. Context nodes of WINDOW controllers. Public attributes of WINDOW controllers. Custom methods of the component controller.

Which of the following items are used in a Web Dynpro Application to transport database data to the user interface? (There are two correct answers). Inbound plug. Supply function. Context node. Interface controller.

Which property of the InputField UI element must be bound to a context attribute?. enable. visible. state. value.

Which hook method exists for all controller types?. wddoonclose( ). wddoonopen( ). wddoinit( ). wddobeforenavigation( ).

You have created a Web Dynpro view that shows data for airline connections between cities. You want to display flight data for a specific date in a different view after the user select a date and presses a button. Which of the following actions you must perform? (There are two correct answers). Set the interface property for key fields. Create and link plugs between the views. Edit the handler method in the view controller. Add a client-side event in the view.

You want to translate dynamic text in a web dynpro. From which abstract class should you inherit?. CL_WD_COMPONENT_ASSISTANCE. CL_WD_CONFIGURATION_MODEL. CL_WD_COMPONENT_SERVICES. CL_WD_CONTEXT_SERVICES.

What process is used to establish the automatic transport of data between the view controller's contextattributes and the UI element in its layout?. Context mapping. Data migration. Data binding. View assembly.
