flex 学习笔记 as自定义组件(三)

actionscript自定义组件，属性：

package contr
{
    import spark.components.BorderContainer;

    public class Ruler extends BorderContainer
    {
        private var _lineLength:Number;

        private var _spacing:Number;
        private var _scale:Number;

        public function Ruler()
        {
            super();
        }

        /**定义最小显示刻度*/
        public function get scale():Number
        {
            return _scale;
        }

        /**
         * @private
         */
        public function set scale(value:Number):void
        {
            _scale = value;
        }

        /**定义最小间距*/
        public function get spacing():Number
        {
            return _spacing;
        }

        /**
         * @private
         */
        public function set spacing(value:Number):void
        {
            _spacing = value;
        }

        /**定义线条的长度*/
        public function get lineLength():Number
        {
            return _lineLength;
        }

        /**
         * @private
         */
        public function set lineLength(value:Number):void
        {
            _lineLength = value;
        }

    }
}

效果：
