У меня есть эта иконка:
Класс
package extra {
import spark.components.Button;
import spark.primitives.BitmapImage;
public class IconButton extends Button {
private var _icon:Class;
[SkinPart(required="false")]
public var iconElement:BitmapImage;
public function get icon():Class {
return _icon;
}
public function set icon(val:Class):void {
_icon = val;
if (iconElement != null) {
iconElement.source = _icon;
}
}
override protected function partAdded(partName:String, instance:Object):void {
super.partAdded(partName, instance);
if (icon !== null && instance == iconElement) {
iconElement.source = icon;
}
}
}
}

CSS
e|IconButton {
skinClass: ClassReference('skins.IconButton');
}
Это прекрасно работает с:
MXML
<extra:IconButton icon="@Embed('../assets/img/animals/dog.png')">Dog Name</extra:IconButton>
Но как я могу это сделать?:
MXML
<extra:IconButton styleName="dog">Dog Name</extra:IconButton>
CSS
e|IconButton {
skinClass: ClassReference('skins.IconButton');
}
.dog {
icon: Embed('../assets/img/animals/dog.png');
}
