Flash 组件定义（AS3）

AS3中定义组件的参数时需要用户元数据，一般通过Inspectable进行指定：

package  {
	
	import flash.display.MovieClip;
	
	
	public class ComponentTest extends MovieClip {
		
		private var _varName:String;
		
		public function ComponentTest() {
			// constructor code
		}
		
		[Inspectable(type="String",defaultValue="auto")]
		public function get varName():String
		{
			return _varName;
		}
		
		public function set varName(v:String):void
		{
			_varName = v;
			trace(this.varName);
		}
	}	
}
