Documentation

Definition

Unique label of an event within a controller.

The label can contain alphanumeric characters and the special character underscore (_). The label must not start with a number, an underscore, or the letter combination "wd".

Use

Events are used for communication between controllers and enable each particular controller to trigger the event handler in another controller.
A cross-component communication can be established using events of the interface controller.

Dependencies

The labels for events, attributes, and methods share the same namespace within the controller - that is, an event cannot have the same name as an attribute or a method.

Example

An event with the name myEvent is triggered by calling the method wd_This->Fire_MyEvent_Evt( ).
