type:String — The type of the event. Event listeners can access this information through the inherited type property.
There is only one type of input/output event: CompleteActionEvent.COMPLETE.
bubbles:Boolean (default = false) — Indicates whether an event is a bubbling event. If the event can bubble, this value is true; otherwise it is false.
When an event occurs, it moves through the three phases of the event flow: the capture phase, which flows from the top
of the display list hierarchy to the node just before the target node; the target phase, which comprises the target node;
and the bubbling phase, which flows from the node subsequent to the target node back up the display list hierarchy.
Some events, such as the activate and unload events, do not have a bubbling phase. The bubbles property has a value of false for events that do not have a bubbling phase.
cancelable:Boolean (default = false) — Indicates whether the behavior associated with the event can be prevented. If the behavior can be canceled, this value is true; otherwise it is false.
