BTW, all InteractiveObjects (superclass
way up) dispatch a MouseEventType.DOUBLE_CLICK event so it may be that don’t
need your workaround anymore. However the metadata for doubleClick is
currently not being passed through so you won’t be able to assign the
handler from MXML, you’ll need to do it manually in AS.

Subject: RE: [flexcoders] Flex 2:
Where is the Timer Class
setInterval() still exists; it's now a function in the flash.util
package. But we do want folks to move to use Timer
instead. Here's a
Flex 2.0 example of using Timer:
<?xml version="1.0"
encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.macromedia.com/2005/mxml">
<mx:Script>
<![CDATA[
import
flash.util.Timer;
import
flash.util.TimerEvent;
import
flash.util.TimerEventType;
private
var timer:Timer;
private
function startTimer():Void
{
timer = new Timer(1000);
timer.addEventListener(TimerEventType.TIMER, timerHandler);
timer.start();
}
private
function stopTimer():Void
{
timer.stop();
timer = null;
}
private
function timerHandler(event:TimerEvent):Void
{
trace("timer");
}
]]>
</mx:Script>
<mx:Button label="Start
Timer" click="startTimer();"/>
<mx:Button label="Stop
Timer" click="stopTimer();"/>
</mx:Application>
Here are a few things to note:
1. A Timer dispatches "timer" events
which you handle like any other
event.
2. When a Timer is first created with 'new', it is
stopped; you have to
use the start() method to start it.
3. This examples creates and destroys a Timer
object each time you click
the Start and Stop buttons. (Setting timer = null
allows it to be
garbage collected.) But you could also create a
Timer object, say at app
initialization, which you keep around, starting
and stopping it multiple
times.

Subject: [flexcoders] Flex 2: Where is the Timer
Class
This is a repost since we can't edit something we
already did. I just
wanted to clerify the subject line.
Flex 2 docs say the old timer functions have been
removed and there is
a Timer Class. However in the docs for the
Timer Class there is a
blank page.
Does anyone know where I can read about the
methods etc of the new
class? Or can tell me what they are?
I am trying to write a new doubleClick checker and
this need a timer.
Thanks
