继承自：Experimental.UIElements.EventBase_1
实现接口：IMouseCaptureEvent
切换到手册当处理程序捕获鼠标变化时发送的事件。
| relatedTarget | 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. |
| Init | Resets the event members to their initial values. |
| GetPooled | Retrieves an event from the event pool. Use this method to retrieve a mouse event and initialize the event, instead of creating a new mouse event. Events obtained from this method should be released back to the pool using Dispose(). |
| bubbles | Whether this event type bubbles up in the event propagation path. |
| currentTarget | 事件的当前目标。当前路径是传播路径中目前正在为其执行事件处理程序的元素。 |
| dispatch | Whether the event is being dispatched to a visual element. An event cannot be redispatched while it being dispatched. If you need to recursively dispatch an event, it is recommended that you use a copy of the event. |
| flags | 事件的标志。 |
| imguiEvent | The IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI. |
| isDefaultPrevented | 如果不应为此事件执行默认操作，则返回 true。 |
| isImmediatePropagationStopped | Whether StopImmediatePropagation() was called for this event. |
| isPropagationStopped | Whether StopPropagation() was called for this event. |
| originalMousePosition | The original mouse position of the IMGUI event, before it is transformed to the current target local coordinates. |
| pooled | Whether the event is allocated from a pool of events. |
| propagationPhase | 当前传播阶段。 |
| target | The target visual element that received this event. Unlike currentTarget, this target does not change when the event is sent to other elements along the propagation path. |
| timestamp | The time when the event was created. |
| tricklesDown | Whether this event is sent down the event propagation path during the TrickleDown phase. |
| Dispose | IDisposable 实现。 |
| GetEventTypeId | Retrieves the type id for this event instance. |
| PreventDefault | Whether the default actions are prevented from being executed for this event. |
| StopImmediatePropagation | Immediately stops the propagation of the event. The event is not sent to other elements along the propagation path. This method prevents other event handlers from executing on the current target. |
| StopPropagation | Stops propagating this event. The event is not sent to other elements along the propagation path. This method does not prevent other event handlers from executing on the current target. |
| Dispose | IDispose 实现。 |
| GetEventTypeId | Retrieves the type id for this event instance. |
| RegisterEventType | Registers an event class to the event type system. |
| GetPooled | Gets an event from the event pool. Use this function instead of creating new events. Events obtained from this method should be released back to the pool using Dispose(). |
| TypeId | Gets the type id for the event class. |
