TooltipEvent

class in UnityEngine.Experimental.UIElements

描述

Event sent to find the first element that displays a tooltip.

This event can be used instead of VisualElement.tooltip to compute tooltips only when they are about to be displayed.

rect	Rectangle of the hovered element in the panel coordinate system.
tooltip	Text to display inside the tooltip box.

Init	Resets the event members to their initial values.

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.
