调用实例

/** * @author Kinglong * @version 0.1 */ package project.test { 	import flash.display.*; import flash.events.*;	 	 	import fl.controls.*; 	 	import project.happy9.browse.ToolTip; 	public class TestToolTip extends Sprite{ 		 		private var _names:Array = ["我是按钮A","我是按钮B","我是按钮C","我是按钮D"]; 		public function TestToolTip() { 			for (var i:uint = 0; i < _names.length; i++ ) { 				var button:Button = new Button(); 				button.label = "button_" + i; 				button.move(2,30*i+10); 				button.addEventListener(MouseEvent.MOUSE_OVER, overHandler); 				button.addEventListener(MouseEvent.MOUSE_OUT, outHandler); 				button.addEventListener(MouseEvent.MOUSE_MOVE, moveHandler);	 				addChild(button); 			} 			new ToolTip(this); 		} 		private function overHandler(event:MouseEvent):void{ 			var arr:Array = event.target.label.split("_"); 			ToolTip.show(_names[int(arr[1])]); 			ToolTip.move(event.stageX,event.stageY); 		} 		 		private function outHandler(event:MouseEvent):void { 			ToolTip.hide(); 		} 		 		private function moveHandler(event:MouseEvent):void { 			ToolTip.move(event.stageX,event.stageY); 		} 	} 	 }
