CallbackEventHandler.RegisterCallback

public void RegisterCallback (EventCallback<TEventType> callback, Experimental.UIElements.Capture useCapture);

public void RegisterCallback (EventCallback<TEventType,TUserArgsType> callback, TUserArgsType userArgs, Experimental.UIElements.Capture useCapture);

パラメーター

callback	The event handler to add.
useCapture	By default the callback will be called during the bubbling phase. Pass Capture.Capture to have the callback called during the capture phase instead.
userArgs	Data to pass to the callback.

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.
