Tight coupling is not "bad", it just has consequences. You will need to judge for yourself the cost/benefit in your case.

Hi Nick, Yes, you can use Meta-data tags to declare an event in your component: [Event(name="eventname", type="path.to.event.class")] This will enable code completion for your custom event. You can then add listeners to your event just as you would to other component events. And no, the parent "shouldn't" dispatch the event, this does cause component coupling. I'm pretty certain though that the people who suggested that did it for the sake of simplicity. In case of a quick-and-dirty prototype, you might not want to extend TitleWindow to create a popup, you can simply create an instance of TitleWindow and add your content to it, in such a case, you don't have the ability to dispatch a custom event from within your popup. Hope this helps, Tibor. www.tiborballai.com --- In flexcoders@yahoogroups.com, Nick Middleweek wrote: > > Hi, > > I'm quite new to Flex and was wondering if it's possible to use Meta Tags to > declare the custom Event that is to be fired from the 'popup' component. > > > And then assign that Custom Event to the function handler in the parent MXML > or AS file? > > > I guess this is the same as Geoff and Vaibhav's suggestion?

Re: [flexcoders] How to dispatchevent in popup window?
Either what Valdor suggested, or in your pop window have a "componentOwner" refrence which you use to dispatch your event: popup: public var componentOwner:DisplayObject ; popup dispatches event: componentOwner.dispatchEvent(...your event...) ; application using the popup: thePopUp = new MyCustomPopUp() ; thePopUp.componentOwner = this ; PopUpManager.addPopUp(thePopUp) ; On Thu, Dec 17, 2009 at 10:05 PM, markflex2007 wrote: > > > Hi, > > I want to dispatch event in popup window and capture the event > in base page. > > Please give me a idea how to do this. > > Thanks > > Mark > > > -- Fotis Chatzinikos, Ph.D. Founder, LivinData Technologies www.styledropper.com fotis.chatzini...@gmail.com,

var myPopup:Panel = new Panel(); myPopup.addEventListener(someEventType, handler); PopUpManager.addPopUp(myPopup, this).
