appart of the delay to answer the question, here is how i make it:
on the custon button class:
public function getTextField():UITextField {
return this.textField;
}
and on the test mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
xmlns:mx="http://www.adobe.com/2006/mxml";
width="100%" height="100%"
backgroundGradientColors="[#c0c0c0, #c0c0c0]"
xmlns:Crud="br.com.calamb.Crud.*"
xmlns:supra="br.com.suprasis.Components.*">
<mx:Glow id="glowImage" duration="1000"
alphaFrom="1.0" alphaTo="0.3"
blurXFrom="0.0" blurXTo="50.0"
blurYFrom="0.0" blurYTo="50.0"
color="0x00FFFF"/>
<supra:Button id="btn" label="a button" width="200" height="200"
rollOver="showMyGlow()"/>
<mx:Script>
<![CDATA[
public function showMyGlow(): void {
glowImage.play([btn.getTextField()]);
}
]]>
</mx:Script>
</mx:Application>
hope its not too late ;)
cheers
