class in UnityEngine.Experimental.UIElements
Interface for classes capable of having callbacks to handle events.
|HandleEvent||Handle an event, most often by executing the callbacks associated with the event.|
|HasBubbleHandlers||Return true if event handlers for the event propagation bubble up phase have been attached on this object.|
|HasCaptureHandlers||Return true if event handlers for the event propagation capture phase have been attached on this object.|
|RegisterCallback||Add an event handler on the instance. If the handler has already been registered on the same phase (capture or bubbling), this will have no effect.|
|UnregisterCallback||Remove callback from the instance.|
