ReadonlypropagationWhich event propagation model is this event type using?
ReadonlytypeThe type of this event instance. Compare this against the static
WidgetEvent."type" in the class or a known string value.
Comparing this value and doing an instanceof check must be equivalent.
ReadonlyuserIs this event capturable by user event handlers?
Note that if the event does not propagate, capturing the event still has an effect; events are handled in the order for which the handlers were added, meaning that if a handler captures the event, the other handlers won't be called.
Static ReadonlytypeThe type of this event class. Each event type should be unique, and have a unique class.
Due to Typescript limitations, no compile error is thrown when this static field is not set at a sub-class. Despite this, the type must be set to a unique string value.
Check if the type of this event instance matches the type of a given event class, asserting that the instance is of the class' type.
Signals to a Root that the pointer is no longer hovering it. This will result in new LeaveEvents being dispatched to hovered Widgets.
