很简单,先是继承Lable ,而后 设置相关属性,比如 小手鼠标、下划线等

package com.waylau.eagleos.components
{
	import spark.components.Label;

	public class LinkButton extends Label
	{
		public function LinkButton()
		{
			super();

			this.useHandCursor = true ;
			this.buttonMode = true ;
			this.mouseChildren = false ;

			this.setStyle("textDecoration","underline");
		}
	}
}
