Flex中判断单击还是双击的方法

Flex中，在双击事件时，单击事件也会同时相应，需要解决双击时，单击事件应该被屏蔽，这个是个问题，但是有解决方案

 

 

今天偶尔看到了这个方法，供大家参考，它是利用时间差来鉴别是单击还是双击：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="absolute"
        width="900" height="538"
        click="clickScreen(event)" doubleClick="dblScreen(event)" keyDown="keyDown(event)"
         doubleClickEnabled="true">
        <mx:Script>
                <![CDATA[
                        private var intervalID:Number = 0 ;
                        private var timeOffset:Number = 300 ;
                       
                        public function fullScreenClick(event:MouseEvent):void{
                                trace("fullScreenClick1");
                        }
                       
                        public function clickScreen(event:MouseEvent):void{
                                clearInterval(intervalID);

                                intervalID = setInterval(doClick,timeOffset);
                       
                        }
                       
                        private function doClick():void
                        {
                                trace("one click");
                       
                        clearInterval(intervalID);
                       
                        }
                       
                                public function dblScreen(event:MouseEvent):void{
                                clearInterval(intervalID);
                                trace("double click");
                        }
                                public function keyDown(event:KeyboardEvent):void{
                                trace("key down");
                        }
                       
                ]]>
