説明

The propagation phases of an event.

When an element receives an event, the event is propagated along a path built from the elements between the panel root and the target element. In the TrickleDown phase, the event is sent from the root element to the target parent element. In the AtTarget phase, the event is sent to the target element. In the BubbleUp phase, the event is sent from the target parent element to the root element. In the last phase, the DefaultAction phase, the event is resent to the target element.
