The simplest way to use custom events is to use the mx.events.DynamicEvent
class.
When the application creates the LoginPopup component, have it listen for
"login" events like this:
var loginPopup:LoginPopup = new LoginPopup();
loginPopup.addEventListener("login", loginHandler);
PopUpManager.showPopup(loginPopup);
Have your LoginPopup class dispatch a "login" event when it closes:
var loginEvent:DynamicEvent = new DynamicEvent("login");
loginEvent.username = usernameTextInput.text;
loginEvent.passwrod = passwordTextInput.text;
dispatchEvent(loginEvent);
Have you application handle the "login" event like this:
private function loginHandler(event:DynamicEvent):void
{
// do something with event.username and event.password
}
If you want to be more formal and "type-safe", you would declare an AS subclass
of Event instead of using DynamicEvent, but that's another lesson.

Thanks. I am not even certain what you mean by dispatching a custom event. I
have heard of Shared Objects though. Can you point me to a goo resource on how
to do this?
Thanks,
