Creating Plugs
Prerequisites
● Before you create a plug, you must create the application entities DC, component, and view
● The Navigation Modeler tool is started for the window unit.
Procedure
...
1. In the function selection area, choose Create Outbound Plug or Create Inbound Plug. In the work area of the Navigation Modeler, click once on the view for which you want to create the plug. It is irrelevant whether you start by defining an outbound plug for the start view or creating an inbound plug for the subsequent view.
To define a view as a start view, you must create an outbound plug for this view using the following wizard: Enter a name for the plug; you can assign the same name to plugs in different views. Follow the wizard.
2. With an inbound plug you can also define an event handler for the view. When you create the event handler, you choose from the following options:
a. Create an event handler with the default name onPlug<myInboundPlug>.
b. Use the predefined event handler with the name onActionRadioButtonPressed.
c. Define an event handler with (partially optional) properties Name, Return type, Event source, Subscribed event.
d. If you do not need an event handler for the inbound plug, you choose Use None.
Result
In the Web Dynpro Explorer, all created plugs are displayed as entities of the view. Graphically, the outbound plug is displayed in the form of a red arrow on the right side of the view in the Navigation Modeler tool. The inbound plug is displayed in the form of a blue arrow on the left side of the view.
