[flexcoders] Problem Adding Effects to Wrapped Label Control (Flex 1.5)

Fri, 09 Dec 2005 15:22:09 -0800

Hello,
 
I'm trying to have a bunch of dynamically updating Labels (think internationalization) all show a Fade effect when their "text" binding source is updated.  Since there is no default "change" event for the control, I've tried going down the path of wrapping the Label and implementing some of the code in my new control.  Doesn't work.  The code below does not fade the label when the button is clicked.  
 
Is it maybe possible to attach a default Fade Effect to my control's "show" Event via Action Script, and just toggle its visibility?
 
 
La code:
 
****************  MXML   ***************
 
<com:FancyLabel xmlns:com="com.*" text="{tempString}" id="lblFancyText"  />

 <mx:Button label="Change Text"
  click="tempString == 'bloo'? tempString='blah' : tempString='bloo';"  />
 
 
****************  Extended Label ***************
 
import mx.effects.*;
import mx.controls.*;

class com.FancyLabel extends mx.controls.Label {

    // Constructor
    public function FancyLabel() {
  
    }
 
   public function showLabel():Void {
      var textFade:Fade = new Fade(this);
      textFade.duration = 2000;
      textFade.alphaFrom = 0;
      textFade.alphaTo = 100;
      textFade.playEffect();
   }
 
     public function set text(val:String):Void {
        super.text = val;
        show Label();
    }
 
}

*************************************** 

Thanks in advance,
