## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.UIElements](/engine/6000.0/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule
* **Inherits from:** [EventBase\<TooltipEvent>](/engine/6000.0/script-reference/unityengine/uielements/eventbase1.md)
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable)

```csharp
public class TooltipEvent : EventBase<TooltipEvent>, IDisposable
```

## Remarks
