flex4 skin 使用外部圖片,當需要自定義一個組件時,需要用到一些外部圖片,對於一些flex3的遺留思想,
希望通過css來控制,
upSkin="{null}"
overSkin="mx.skins.halo.ButtonSkin"
downSkin="mx.skins.halo.ButtonSkin"
disabledSkin="mx.skins.halo.ButtonSkin"
在flex4中,對於 spark 組件就不行了
flex4 創建css 就不多介紹了
現以button引入外部image (常用*.png,*.swf中圖片)爲例:
<?xml version="1.0" encoding="utf-8"?> <s:SparkButtonSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:fb="http://ns.adobe.com/flashbuilder/2009" minWidth="21" minHeight="21" alpha.disabled="0.5"> <fx:Metadata> <![CDATA[ /** * @copy spark.skins.spark.ApplicationSkin#hostComponent */ [HostComponent("spark.components.Button")] ]]> </fx:Metadata> <fx:Script fb:purpose="styling"> <![CDATA[ import spark.components.Group; /* Define the skin elements that should not be colorized.
