dispatchEvent

[Darrin Kay]

ok all i want to do is add a eventListner to a variable, so when it changes
value I kick off a event.......  why is it so damm hard?  I am using
cairngorn, and the variable is in the model scope.  But I can not for the
life of me figure how to get the dispatch / addeventlister to work and where
it goes and what packages need to be added


this is the last step I need to get done for a release any help would be
sweet

is it Watcher that you're looking for?
something along these lines :
(warning - straight off the top of my head so could well be wrong in detail at least. best check the docs)

private function addWatcher():void
{
    Watcher.watch(yourModelInstance,"yourModelProperty",onYourModelPropertyChanged);
}

private function onYourModelPropertyChanged(changeEvent:ChangeEvent)
{
    trace(changeEvent.newValue);
    //make and despatch your event here
}

I expect there are other ways to it as well..

ooops, maybe that should be ChangeWatcher.
Apologies, I've just got off a 14 hour overnight flight in cattle class I'm afraid!
