# VgCuePoints @Directive

Directive to get events on a track object. `VgCuePoints` are defined as an attribute in a `track` element.

`VgCuePoints` will add `cues` property to the track element with all the `VTTCue` objects loaded by the `track` element. For example, you can use the `cues` property to list all the cues with a `*ngFor` or to populate the `VgScrubBarCuePoints` component.

## Outputs

| Output | Description |
|--- |--- |
| onEnterCuePoint | Triggered when player time is bigger than `start` cue point property. |
| onExitCuePoint  | Triggered when player time moves to a position lower than cue point `start` property. |
