EventBase

class in UnityEngine.Experimental.UIElements

Description

The base class for all UIElements events.

bubbles	Whether this event type bubbles up in the event propagation path.
currentTarget	The current target of the event. The current target is the element in the propagation path for which event handlers are currently being executed.
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	Flags for the event.
imguiEvent	The IMGUIEvent at the source of this event. The source can be null since not all events are generated by IMGUI.
isDefaultPrevented	Return true if the default actions should not be executed for this event.
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	The current propagation phase.
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	Implementation of IDisposable.
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.

Init	Resets all event members to their initial values.

Registers an event class to the event type system.
