User Idle Time (no mouse movement, no keyboard strockes) in Flex

So you want to lock the Flex application or keep track of the user’s idle time, or a lock timeout. The user idle time which is when the application is running, but the user does not press any keyboard strokes nor any mouse movements, the idleCounter launches every 100 ms.

To do this in Actionscript, we import:

import mx.managers.SystemManager;
import mx.events.FlexEvent;
import mx.core.mx_internal;
use namespace mx_internal;

On the creation complete of the Main Application (or use your own logic), place the code:

private function onCreationComplete():void {
   systemManager.addEventListener(FlexEvent.IDLE, userIdle);
}

private function userIdle(e:FlexEvent):void {
   if(e.currentTarget.mx_internal::idleCounter == 600){ // 60 Secs Elapsed while Being Idle!!
       // do something when the application has been idle for 60 seconds
       Alert.show("You have been idle for more than " + "60" + " minutes", "You have been signed out");
   }
}
