## Properties

| Property                                                                                                        | Description                                                                                                                                                                                      |
| --------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| [relatedTarget](/engine/6000.6/script-reference/unityengine/uielements/mousecaptureeventbase1/relatedtarget.md) | In the case of a MouseCaptureEvent, this property is the IEventHandler that loses the capture. In the case of a MouseCaptureOutEvent, this property is the IEventHandler that gains the capture. |

| [GetPooled](/engine/6000.6/script-reference/unityengine/uielements/mousecaptureeventbase1/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. |
