组件Button的简单用法

package  {
	
	import flash.display.MovieClip;
	import flash.events.MouseEvent;
	import fl.controls.*;
	
	public class ButtonMain extends MovieClip {
		private var btn:Button;
		
		public function ButtonMain() {
			// constructor code
			btn = new Button();
			stage.addChild(btn);
			//指示他是否有边框  默认为false
			btn.emphasized = true;
			//btn.enabled = false;
			btn.label = "chenlong";
			//指示此按钮是否可以被切换
			btn.toggle = true;
			btn.visible = false;
			btn.addEventListener(MouseEvent.MOUSE_DOWN,a);
			btn.addEventListener(MouseEvent.MOUSE_UP,b);
		}
		private function a(e):void
		{
			trace(btn.selected);
		}
		private function b(e):void
		{
			//trace(btn.selected);
		}
	}
	
}
