| bubbles | Returns whether this event type bubbles up in the event propagation path during the BubbleUp phase. |
| currentTarget | The current target of the event. This is the VisualElement, in the propagation path, for which event handlers are currently being executed. |
| dispatch | Indicates 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. |
| eventTypeId | Retrieves the type ID for this event instance. |
| ignoreDisabledElements | If this property is true, callbacks for this event are not invoked when the current target is disabled, unless those callbacks are registered using the CallbackOptions.IncludeDisabled option. |
| imguiEvent | The IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI. |
| isImmediatePropagationStopped | Indicates whether EventBase.StopImmediatePropagation() was called for this event. |
| isPropagationStopped | Returns true if EventBase.StopPropagation() or EventBase.StopImmediatePropagation() 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 | The current propagation phase for this event. |
| 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 dispatched, in milliseconds. |
| tricklesDown | Returns whether this event is sent down the event propagation path during the TrickleDown phase. |
