问题描述

我有什么，我认为这是一个简单的问题就在这里。我打电话一个基本的计时器上登录成功，随后通过设置一对夫妇处理程序，刷新时间表的一些数据。 （我还没有粘贴的定时器处理程序，因为我不认为它很重要他们做什么）无论如何，我想关闭这些定时刷新，当应用程序处于闲置状态，但是这样的：

 如果（e.currentTarget.mx_internal :: idleCounter＆GT; 15000）{
 

永远不会被触发。我presume这是因为不同的方式的Flex 4正在处理这些对象，但我无法找到它的文档中的任意位置。搜索idleCounter出现空白，甚至。

 保护功能getUserByIDResult_resultHandler（事件：的ResultEvent）：无效
{

    VAR SYSMAN：ISystemManager包含= FlexGlobals.topLevelApplication.systemManager;
    sysMan.addEventListener（FlexEvent.IDLE，userIdle）;

    session.user = event.result的用户;

    定时器=新的定时器（5000）;
    timer.addEventListener（TimerEvent.TIMER，timer_short）;
    timer.start（）;

    定时器2 =新的定时器（10000）;
    timer2.addEventListener（TimerEvent.TIMER，timer_long）;
    timer2.start（）;

    currentState的=主;
}


私有函数userIdle（E：FlexEvent）：无效{
    如果（e.currentTarget.mx_internal :: idleCounter＆GT; 15000）{
        timer.stop（）;
        timer2.stop（）;
    }
    如果（e.currentTarget.mx_internal :: idleCounter＆LT; 15000）{
        如果（timer.running == FALSE）{
            timer.start（）;
            timer2.start（）;
        }
    }
}
 

解决方案

所以经过一些调查研究，我决定空闲事件是真正前进的道路。这里有一个简单的例子（注意时机是近似，这是我的目的确定，可能是最空闲的定时器）。

 私有函数userIdle（E：FlexEvent）：无效{
            idleCounter ++;
            跟踪（idleCounter）;
            如果（idleCounter→100）{
                seconds_since_idle + = 10;
                idleCounter = 0;
                如果（seconds_since_idle→60）{
                    追踪（空闲超过1分钟）;
                    如果（timer.hasEventListener（TimerEvent.TIMER））{
                        timer.removeEventListener（TimerEvent.TIMER，timer_short）;
                    }
                }
                如果（seconds_since_idle＆GT; 180）{
                    跟踪（空转3分钟以内）;
                    sysMan.removeEventListener（FlexEvent.IDLE，userIdle）;
                    session.user = NULL;
                    currentState的=登陆;
                    Alert.show（你已被注销因不活动。
                        警报，
                        Alert.OK）;
                }
            }
        }
 

I have what I THINK is a simple problem here. I'm calling a basic timer on login success, followed by setting up a couple handlers to refresh some data on a schedule. (I haven't pasted the timer handlers cause i don't think it matters what they do) Anyway, I'm trying to shut OFF those timed refreshes when the app is IDLE, but this:

    if (e.currentTarget.mx_internal::idleCounter > 15000) {

Never gets triggered. I presume it's because of the different way Flex 4 is handling these objects, but I can't find it anywhere in the documentation. Searching for idleCounter comes up empty, even.

protected function getUserByIDResult_resultHandler(event:ResultEvent):void
{

    var sysMan:ISystemManager = FlexGlobals.topLevelApplication.systemManager;
    sysMan.addEventListener(FlexEvent.IDLE, userIdle);

    session.user = event.result as User;

    timer = new Timer(5000);
    timer.addEventListener(TimerEvent.TIMER, timer_short);
    timer.start();

    timer2 = new Timer(10000);
    timer2.addEventListener(TimerEvent.TIMER, timer_long);
    timer2.start();

    currentState='Main';
}


private function userIdle(e:FlexEvent):void {
    if (e.currentTarget.mx_internal::idleCounter > 15000) {
        timer.stop();
        timer2.stop();
    }
    if (e.currentTarget.mx_internal::idleCounter < 15000) {
        if ( timer.running == false) {
            timer.start();
            timer2.start();
        }
    }
}

解决方案

So after some more research, I decided that the Idle event was really the way forward. Here's a simplified example (note the timing is "approximate", which is OK for my purposes, and probably most idle timers).

private function userIdle(e:FlexEvent):void {
            idleCounter++;
            trace(idleCounter);
            if (idleCounter > 100) {
                seconds_since_idle += 10;
                idleCounter = 0;
                if (seconds_since_idle > 60) {
                    trace("idle longer than 1 minute");
                    if (timer.hasEventListener(TimerEvent.TIMER)) {
                        timer.removeEventListener(TimerEvent.TIMER, timer_short);
                    }
                }
                if (seconds_since_idle > 180) {
                    trace("idle longer than 3 minutes");
                    sysMan.removeEventListener(FlexEvent.IDLE, userIdle);
                    session.user = null;
                    currentState='Login';
                    Alert.show("You have been logged out due to inactivity.",
                        "Alert", 
                        Alert.OK);
                }
            } 
        }
