# eventID

The event ID for the receiver.

```
var eventID: AEEventID { get }
```

## Discussion

The event ID (a four-character code) for the receiver, or 0 if an error occurs.

The receiver must be an Apple event. An Apple event is identified by its event class and event ID, a pair of four-character codes stored as 32-bit integers. For example, the `open` Apple event from the Standard suite has the four-character code `'odoc'` (defined as the constant `kAEOpen` in `AE.framework`, a subframework of `ApplicationServices.framework`).
