[flexcoders] fade when image changes

[Kim Reddington]

I am trying to use 
the PhotoViewer sample to  help me create a fade effect.  In the below 
code, I have a component that successfully fades in when the component 
(cardfileToImage) is created.  I would like the first image to fade out 
while a new image fades in when the user selects a new image.   Just 
like the PhotoViewer sample.  PhotoViewer is fading an actualy image, but I 
need to fade a whole component because it is an image pair.  How can I get 
the app to fade the images in and out when the user selects a new image 
pair?  The component fades properly when it is first created, but I'm not 
sure what to use to tell it to fade when the user select a new image.  The 
new image does appear, but does not fade in.
 
Here is the code I 
have for the fading:
 
<?xml 
version="1.0" encoding="utf-8"?>
 
<mx:Canvas 
xmlns:mx="http://www.macromedia.com/2003/mxml" 
xmlns="*">
 
    
<mx:Script>   
<![CDATA[        var 
activeControl;  public var 
src:String;/*        public function 
loadCard() 
{            if 
(activeControl==card1) 
{               
// card2.imageName = 
imageName;            
} else 
{                
card1.imageName = 
imageName;            
}        }*/  function set 
imageName(src) 
{            if 
(activeControl==card1) 
{                
card2.imageName = 
src;            } 
else 
{                
card1.imageName = 
src;            
}        }
 
        function 
mix(showObj, hideObj) 
{            
activeControl=showObj;            
var e1 = new 
mx.effects.Fade(hideObj);            
e1.duration=800;            
e1.alphaTo = 0;
 
            
var e2 = new 
mx.effects.Fade(showObj);            
e2.duration=800;            
e2.alphaTo = 100;
 
            
var mixEffect = new 
mx.effects.Parallel();            
mixEffect.addChild(e1);            
mixEffect.addChild(e2);            
mixEffect.playEffect();           
}      ]]>    
</mx:Script>
 
<cardfileToImage 
id="card1" sizeType="" creationComplete="mix(card1, 
card2)"/><cardfileToImage id="card2" sizeType="" 
creationComplete="mix(card2, card1)"/>
 
</mx:Canvas>
 
 
Thank you so 
much,
Kim
