# MouseUpEvent

> This event is sent when a mouse button is released.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.UIElements](/engine/6000.6/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule
* **Inherits from:** [MouseEventBase\<MouseUpEvent>](/engine/6000.6/script-reference/unityengine/uielements/mouseeventbase1.md)
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable), [IMouseEvent](/engine/6000.6/script-reference/unityengine/uielements/imouseevent.md)

```csharp
public class MouseUpEvent : MouseEventBase<MouseUpEvent>, IDisposable, IMouseEvent
```

## Remarks

The mouse up event is sent to a visual element when a mouse button is released inside the element. A MouseUpEvent uses the default mouse event propagation path: it trickles down, bubbles up and can be cancelled. Disabled elements won't receive this event by default.

## Constructors

| Constructor                                                                                   | Description                                                                                                                           |

| [MouseUpEvent()](/engine/6000.6/script-reference/unityengine/uielements/mouseupevent/ctor.md) | Constructor. Avoid creating new event instances. Instead, use GetPooled() to get an instance from a pool of reusable event instances. |

## Methods

| Method                                                                              | Description                                       |
| ----------------------------------------------------------------------------------- | ------------------------------------------------- |
| [Init](/engine/6000.6/script-reference/unityengine/uielements/mouseupevent/init.md) | Resets the event members to their initial values. |

| [GetPooled](/engine/6000.6/script-reference/unityengine/uielements/mouseupevent/getpooled.md) | Gets an event from the event pool and initializes it with the given values. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use `Dispose()` to release them. |
