void HandleEvent(EventBase evt)
Parameters
The event to handle.
Remarks
The EventDispatcher might invoke this method multiple times for the same event: once for each propagation phase and each target along the event's propagation path if it has matching callbacks or overrides default actions for the event.
Note: Do not use this method to intercept all events whose propagation path includes this element. There is no guarantee that it will or will not be invoked for a propagation phase or target along the propagation path if that target has no callbacks for the event and has no default action override that can receive the event.
