Yes, I'd be happy to share :) #1) I just want to know how to do it, to put my mind at ease that I can do this if I DO ever have the need #2) The reason it's in my modelLocater is because, my debugText variable is held here - and I have a floating Debug Window which stays open during the development phase of my application. In my Debug Popup Window, I simply have a TextArea Control, in which I bind the model.debugText variable to. Then whenever I want to perform a trace, I just run my "model.updateDebug()" function, which in turn, appends any new Debug Information, to the model.debugText variable. And voila! my Debug Window gets updated with the debugText. #3) Any time Text is added to a TextArea control, and the text size exceeds the currently displayed limit, ScrollBars appear - and any additional text added, gets placed below the visible area. With the nature of the Text being debugging information, I am most interested in ONLY the latest text being added - so I need to automatically scroll my TextArea all the way to the bottom. I want within my grasp, the ability to manually dispatch the event, which causes my TextInput Control to scroll all the way to the bottom. #4) I know that I could simply create an event listener for the TextArea residing in my DebugWindow, that any time a "change" event occurs, to run a function that causes the ScrollBars to move all the way to the bottom. So with all that said, I guess bottom line, I am asking this: How can I write BOTH, and Event listener to listen for events, and ALSO an Event Dispatcher to dispatch the event, whereas I can ANYWHERE inside of my application, trigger this to happen any time I like?? I was under the impression, that Events get broadcasted "Application Wide" - and that anything with an active listener running, will capture and respond to the event. I guess I was sadly mistaken, because I am hitting a MAJOR brick with all of this. I would love to hear more input on this topic :) Thanks, Mike

Could you please share? Also, could this be a case where the Observe tag could help you? http://weblogs.macromedia.com/paulw/archives/2006/05/the_worlds_smal.cfm Thanks Sam On 1/9/07, Mike Anderson <[EMAIL PROTECTED]> wrote: Yes, I understand this - But what about a generic class, that does NOT extend any other classes (which have the IEventDispatcher as part of their makeup) In my generic class (in this case, my ModelLocater which is part of a Cairngorm-based application), it doesn't natively have anything in there which includes the EventDispatcher stuff. So, I wanted to see what the bare minimum requirements would be, in order to Dispatch an Event from a Class File that doesn't "extend" or "implement" anything else. Also, I DO have the [Bindable] Metatag on this class, and even know I don't get any code-hinting whenever I type any "dispatchEvent" type code, I don't get any Compiler Errors either... That struck me as odd, but with what Tracy just mentioned, it does answer a few questions... So I guess, the [Bindable] Metatag is a quick way to add this functionality, but I am just curious if I wanted to accomplish this via some other means. Thanks for the info on this topic :) Mike ________________________________ From: flexcoders@yahoogroups.com <http://ups.com/> [mailto: flexcoders@ <mailto:flexcoders@> yahoogroups.com] On Behalf Of Sergey Kovalyov Sent: Tuesday, January 09, 2007 1:28 PM To: [EMAIL PROTECTED] ups.com <http://ups.com/> Subject: Re: [flexcoders] Dispatching an Event from a Class Just call dispatchEvent() (e. g. dispatchEvent(new Event(Event.CHANGE))) in any class that implements IEventDispatcher (e. g. all the EventDispatcher successors). Note, that UIComponent and all its successors implement IEventDispatcher, so dispatchEvent() could be called in any subclass of Box, ComboBox, Label, TextArea, HSlider, etc: package { import mx.controls.HSlider; public class MyHSlider extends HSlider { public function MyHSlider() { super(); dispatchEvent(new Event("instanceConstructed")); } } } On 1/9/07, Mike Anderson <[EMAIL PROTECTED]> wrote: Hello All, I am attempting to dispatch an Event from a generic Class File, and I guess I'm not doing it correctly. I was hoping, that I could simply do this: import mx.events.IEventDispatcher And then in my function, I could simply dispatch the event like this: IEventDispatcher.dispatchEvent( event ); But it doesn't allow me to do this. In the meantime, I extended my Class to use the UIComponent, which automatically pulls in all the EventDispatcher stuff. Of course, it's silly for me to do this, since I really don't have a need to extend the UIComponent class. There must be a way, to import the proper Class, in order to simply dispatch events. Any advice? Thanks in advance for your help, Mike
