# Notification class

Namespace: [Eto.Forms](https://eto.picoe.ca/api/namespace/eto.forms.md) · Assembly: [Eto](https://eto.picoe.ca/api/assembly/eto.md)

```cs
[Handler(Notification.IHandler)]
public class Notification : Widget
```

System toast notification.

**Remarks:** Create a new instance of this class for each notification sent as they are not reusable. The ID and [Notification.UserData](https://eto.picoe.ca/api/type/eto.forms.notification/userdata.md) should be used to specify what action would happen when the user clicks the notification (if applicable). All notifications should be handled by the [Application.NotificationActivated](https://eto.picoe.ca/api/type/eto.forms.application/notificationactivated.md) event. Note that in some platforms (e.g. macOS), the application may have a notification clicked when the application isn't even started. In this case, the application is started an then sent the notification to the [Application.NotificationActivated](https://eto.picoe.ca/api/type/eto.forms.application/notificationactivated.md) immediately.
