# Listening to player events

To list to playback and player related events, you have to make your view controller to implement the `FPFlowplayerDelegate` protocol, then add the delegates to the `FPFlowplayerViewController`.


```swift
class PlayerViewController: UIViewController, FPFlowplayerDelegate {

    let flowplayerViewController = FPFlowplayerViewController()

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)

        ...

        flowplayerViewController.addPlayerDelegate(self)
    }
}
```

## FPFlowplayerDelegate events

All the available callback and events that `FPFlowplayerDelegate` supports are as follows.


```swift
/**
Callback for FPIdleEvent.
- Parameter event: The payload of the event.
*/
func onIdle(event: FPIdleEvent)
