Hi, I'm trying to add a dropShadow to a button like so:
public class DropShadowButton extends Button
{
private var ds:DropShadowFilter;
public function DropShadowButton():void
{
super();
ds = new DropShadowFilter();
var a:Array = new Array();
a.push(ds);
this.textField = new UITextField();
this.textField.antiAliasType =
flash.text.AntiAliasType.ADVANCED;
this.textField.filters = a;
this.addChild(textField);
}
}
which works fine until, inside UIComponent.as, I throw an error reading:
TypeError: Error #2007: Parameter antiAliasType must be non-null.
at flash.text::TextField/set antiAliasType()
at
mx.core::UITextField/validateNow()[C:\dev\GMC\sdk\frameworks\mx\core\UITextField.as:1427]
at mx.core::UITextField/set
nestLevel()[C:\dev\GMC\sdk\frameworks\mx\core\UITextField.as:956]
out of these lines of code:
if (child is ILayoutManagerClient)
ILayoutManagerClient(child).nestLevel = nestLevel + 1;
else if (child is UITextField)
UITextField(child).nestLevel = nestLevel + 1;
Can anyone shed any light on what's going on under the hood?
