interfaces

Hi All,

1)

Is a "component interface" and "interface controller" the same thing?

I can imagine that a component can have its own interface

and also the controller .

2)

How is it to understand. Pictorially, is a controller inside of component or not ?

If so then why do they not take only one interface ?

Thanks in advance

ilhan

    Hi see the below stmt's.

    .

    Within Web Dynpro components, events can be defined for all controllers except view controller, interface view controller, and configuration controller. This is due to the fact that, according to the Web Dynpro programming model, the non-view controllers do not know the existing view controllers and, therefore, cannot subscribe to the events of the view controllers. Events may contain parameters.

    So we define in the component interface controller (controller representation of the Web Dynpro component for outer users) an event called InnerEvent with a parameter of type string. When the controller of the view form uses this component interface controller, in an event handler of the view controller, a public method of the component interface controller can trigger the InnerEvent.

    Final Conclusion:So there is no seperate InterfaceController(this is nothing but component Interface Controller)

    Purpose:In order to use one component in another pgm we r using interface controller.

    Regards
