Defined by EventDispatcher
dispatchEvent (event:Event):Bool
Dispatches an event into the event flow. The event target is the
EventDispatcher object upon which the dispatchEvent()
method
is called.
Parameters:
event | The Event object that is dispatched into the event flow. If
the event is being redispatched, a clone of the event is
created automatically. After an event is dispatched, its
|
---|
Throws:
Error | The event dispatch recursion limit has been reached. |
---|
Returns:
A value of true
if the event was successfully
dispatched. A value of false
indicates failure or
that preventDefault()
was called on the event.
hasEventListener (type:String):Bool
Checks whether the EventDispatcher object has any listeners registered for
a specific type of event. This allows you to determine where an
EventDispatcher object has altered handling of an event type in the event
flow hierarchy. To determine whether a specific event type actually
triggers an event listener, use willTrigger()
.
The difference between hasEventListener()
and
willTrigger()
is that hasEventListener()
examines only the object to which it belongs, whereas
willTrigger()
examines the entire event flow for the event
specified by the type
parameter.
When hasEventListener()
is called from a LoaderInfo
object, only the listeners that the caller can access are considered.
Parameters:
type | The type of event. |
---|
Returns:
A value of true
if a listener of the specified type
is registered; false
otherwise.
removeEventListener (type:String, listener:Dynamic ‑> Void, useCapture:Bool = false):Void
Removes a listener from the EventDispatcher object. If there is no matching listener registered with the EventDispatcher object, a call to this method has no effect.
Parameters:
type | The type of event. |
---|---|
useCapture | Specifies whether the listener was registered for the
capture phase or the target and bubbling phases. If the
listener was registered for both the capture phase and
the target and bubbling phases, two calls to
|
willTrigger (type:String):Bool
Checks whether an event listener is registered with this EventDispatcher
object or any of its ancestors for the specified event type. This method
returns true
if an event listener is triggered during any
phase of the event flow when an event of the specified type is dispatched
to this EventDispatcher object or any of its descendants.
The difference between the hasEventListener()
and the
willTrigger()
methods is that hasEventListener()
examines only the object to which it belongs, whereas the
willTrigger()
method examines the entire event flow for the
event specified by the type
parameter.
When willTrigger()
is called from a LoaderInfo object,
only the listeners that the caller can access are considered.
Parameters:
type | The type of event. |
---|
Returns:
A value of true
if a listener of the specified type
will be triggered; false
otherwise.
