The Original Code is Soma.
The Initial Developer of the Original Code is Romuald Quantin.
Initial Developer are Copyright (C) 2008-2009 Soundstep. All Rights Reserved.

Usage:
Framework events dispatched through a single dispatcher related to the BackgroundManager (Soma.getInstance().background).

The type SHOW and HIDE are commands:

  new BackgroundEvent(BackgroundEvent.SHOW, "myBackground").dispatch();
  new BackgroundEvent(BackgroundEvent.HIDE, "myBackground").dispatch();
     

The type TRANSITION_IN and TRANSITION_OUT are not commands and the listeners can be added on the Soma class (can be default prevented):

  Soma.getInstance().addEventListener(BackgroundEvent.TRANSITION_IN, eventHandler);
  Soma.getInstance().addEventListener(BackgroundEvent.TRANSITION_OUT, eventHandler);

Public Properties
 PropertyDefined by
 Inheriteddata : *
The data property can be used to hold information to be passed with the event in cases where the developer does not want to extend the CairngormEvent class.
CairngormEvent
  id : String
id of the background (attribute id in a node child of the backgrounds node of the XML Site Definition).
BackgroundEvent
Public Methods
 MethodDefined by
  
BackgroundEvent(type:String, id:String = "", bubbles:Boolean = true, cancelable:Boolean = false)
Creates a BackgroundEvent instance, the event can dispatch itself using the method dispatch (command).
BackgroundEvent
  
clone():Event
Duplicates an instance of an Event subclass.

Returns a new Event object that is a copy of the original instance of the Event object.
BackgroundEvent
  
dispatch():Boolean
Dispatch this event via the Cairngorm event dispatcher.
BackgroundEvent
  
toString():String
Returns a formatted string to display event information.
BackgroundEvent
Public Constants
 ConstantDefined by
  HIDE : String = "com.soma.events.BackgroundEvent.HIDE"
[static] Soma command to display a background using the id from the XML Site Definition, use from anywhere in the code:

The parameter should the ID of the background (id attribute in the XML Site Definition)

new BackgroundEvent(BackgroundEvent.HIDE, "myBackground").dispatch();
BackgroundEvent
  SHOW : String = "com.soma.events.BackgroundEvent.SHOW"
[static] Soma command to display a background using the id from the XML Site Definition, use from anywhere in the code:

The parameter should the ID of the background (id attribute in the XML Site Definition)

new BackgroundEvent(BackgroundEvent.SHOW, "myBackground").dispatch();
BackgroundEvent
  TRANSITION_IN : String = "com.soma.events.BackgroundEvent.TRANSITION_IN"
[static] Indicates when a background is about to be displayed by the BackgroundManager instance (Soma.getInstance().background).

Soma.getInstance().addEventListener(BackgroundEvent.TRANSITION_IN, eventHandler);
BackgroundEvent
  TRANSITION_OUT : String = "com.soma.events.BackgroundEvent.TRANSITION_OUT"
[static] Indicates when a background is about to be hidden by the BackgroundManager instance (Soma.getInstance().background).

Soma.getInstance().addEventListener(BackgroundEvent.TRANSITION_OUT, eventHandler);
BackgroundEvent
Property detail
idproperty
public var id:String

id of the background (attribute id in a node child of the backgrounds node of the XML Site Definition). The id is also the DisplayObject name in the container of the backgrounds (Soma.getInstance().background.container).

Constructor detail
BackgroundEvent()constructor
public function BackgroundEvent(type:String, id:String = "", bubbles:Boolean = true, cancelable:Boolean = false)

Creates a BackgroundEvent instance, the event can dispatch itself using the method dispatch (command).

Parameters
type:String — The type of the event, accessible as BackgroundEvent.type.
 
id:String (default = "") — The id of the background.
 
bubbles:Boolean (default = true) — Determines whether the Event object participates in the bubbling stage of the event flow. The default value is false.
 
cancelable:Boolean (default = false) — Determines whether the Event object can be canceled. The default values is false.
Method detail
clone()method
public override function clone():Event

Duplicates an instance of an Event subclass.

Returns a new Event object that is a copy of the original instance of the Event object. You do not normally call clone(); the EventDispatcher class calls it automatically when you redispatch an event—that is, when you call dispatchEvent(event) from a handler that is handling event.

The new Event object includes all the properties of the original.

Returns
Event — A new Event object that is identical to the original.
dispatch()method 
public override function dispatch():Boolean

Dispatch this event via the Cairngorm event dispatcher.

Returns
Boolean
toString()method 
public override function toString():String

Returns a formatted string to display event information.

Returns
String — A String.
Constant detail
HIDEconstant
public static const HIDE:String = "com.soma.events.BackgroundEvent.HIDE"

SHOWconstant 
public static const SHOW:String = "com.soma.events.BackgroundEvent.SHOW"

Soma command to display a background using the id from the XML Site Definition, use from anywhere in the code:

TRANSITION_INconstant 
public static const TRANSITION_IN:String = "com.soma.events.BackgroundEvent.TRANSITION_IN"
