Dispatch an Event at HeaderRenderer

Hi all!
I have a HeaderRenderer which has a checkbox and a button. The checkbox it is replaced by an image when teh updatedisplaylist event is dispatched, so far this work fine. Even though when I add a couple of headerrenderers to a couple of datagrid columns. These new headerrenderers have a combobox and a label, the column with the 1st headerrenderer stops refreshing itself... but whe you click or move the sidescroll bar of the datagrid the header refresh itself and shows the image. What am I doing wrong with the other headerrenderers or how can I listen and fire an event within a headerrenderer to update the display?. Thanks in advance.
Frank
P.S. I'm using Flex builder 4.5, MX Datagrid

You're listening for "backtomain" but dispatching "myevent".

Why doesn't the TimeTrait dispatch currentTimeChange event?

There are cases when I would like a VideoElement's TimeTrait to dispatch currentTimeChange events in addition to complete and durationChange events. I'm wondering what the logic is to not have this trait dispatching this event from the currentTimeChangeEnd protected method? Seems the only way to track an elements current time is to track it at the player level.

You can setup your own timer and track the currentTime values inside a TimeTrait instance.
I don't know why the TimeTrait doesn't dispatch the currentTimeChange event, but I suppose that this is intentional - you don't want to provide this kind of utility methods at this low level API level.
ionflow, why isn't MediaPlayer API good enough for you? Why do you need to get these events at the TimeTrait level?

Dispatching an event during check-in process

I am a newbie to adobe illustrator CS6 sdk.
I am trying to add an event listener to the existing check-in menu item.
When check-in is invoked i want to dispatch an event to cs extension.
I got hold of the check-in menu item in AIMenuItemHandle, but i do not find any functions to add any event listeners to the check-in option.
How do I add event listener to the check-in menu item?
Thanks in Advance,
Senthil.

I didn't see a notifier myself, but I was hoping I was just not noticing it.
There isn't really an SDK for walking through menus & such. the AICommandManager.h header has some functions for searching for CommandIDs, but a CommandID is basically a keyboard shortcut. So that will only work if there's one associated with the menuitem you're trying to invoke. If so, there look to be some methods in that header for searching for it based on partial name matching -- localized or not. That might get you the CommandID you want, assuming its available. It must not always be avaialble, because I don't see a 'Check in' option in my version of CS6 -- presumbly this requires VersionCue or whatever it is Adobe has for this?

Dispatching an event from a PDF to AIR?

I would like to put a button in a PDF using Acrobat, that,
when clicked, dispatches an event that can be picked up by my
displaying AIR application. The PDF is being displayed in AIR using
HTMLLoader in an HTML object.
Is this possible?

Try the following. On the first frame of the movieclip place
the following code.
// Event Routines //
var dispatchEvent:Function;
var addEventListener:Function;
var removeEventListener:Function;
mx.events.EventDispatcher.initialize(this);
Then on the "x" frame of the movieclip, place the following
code:
var evt:Object = new Object();
evt.type = "framereached"; // this can be whatever you wish
to listen for
evt.target = this;
dispatchEvent(evt);
This is how you would do this in a class and it should work
just as well if coded directly onto a frame. However, to make this
more versatile I would place it in a class with a public function,
for example, name throwEvent(). This public method would then
execute the above code and could be called from any frame. You
could even add another item to the evt object that would contain
the frame the executed the event.

Dispatching an event from a command

Hi,
In one for my commands in the Cairngorm based application I'm working on I need to dispatch a event to amend the view. In my command I'm amending some value objects in a ArrayCollection, which is the data source for a List component in my view. Once I completed my changes to these value objects I'd like to dispatch a event to resort the ArrayCollection and update my view to the new order.
What is the best approach for dispatching an event in the command?
Thanks
Stephen

Great question - I'm currently sorting out how to do this myself. I'm new to Cairngorm but have a decent amount of experience with Flex. Here are my thoughts:
Cairngorm promotes decoupling of the data model and front controller/commands from the view - which is appropriate for an MVC framework. Data binding supports this seperation (to an extent) and keeps the view up to date with the model in 'real time'. Data binding does not however provide an intuitive mechanism for reacting to cairngorm event results. So here a few solutions I've been tossing around:
1. Rely on Built in Flex events such as the datagrid's dataChange event to trigger a reaction.
2. Create view state variables in the model that, when changed through the front controller / commands, dispatch custom events from within their VO's / setters / ect.
3. Dispatch custom events directly from front controller / commands.
4. Create custom (or override existing) item renderers that self-transition / tween when changed as a result of data binding.
I'm sure there are other ways to do what we want, but I'm out of ideas. Which approach to take very well depends on how strongly you'd like to adhere to the MVC concept. Commands that dispatch generic events as their messages may or may not be acceptable to you - but they provide a straitforward way to trigger view related reactions without relying on data binding events. I'd be interested to know if Cairngorm 3 will address this challenge...
Let me know what you decide on if and when you make a choice!

Dispatching an event from a MovieClip???

Hello, can somebody tell me if there is a way to dispatch an
event from a Movieclip?, I tried to dispatch an event from a class
and all ran ok. But now, if I have a Movieclip on my scenario and I
want that when it arrive to "x" frame it dispatch an event that
could be catched by a listener on the _root, what I have to do?
(without doing use of classes), thanks a lot.

Try the following. On the first frame of the movieclip place
the following code.
// Event Routines //
var dispatchEvent:Function;
var addEventListener:Function;
var removeEventListener:Function;
mx.events.EventDispatcher.initialize(this);
Then on the "x" frame of the movieclip, place the following
code:
var evt:Object = new Object();
evt.type = "framereached"; // this can be whatever you wish
to listen for
evt.target = this;
dispatchEvent(evt);

How to dispatch an event to the host application?

Can I create a keyboardEvent and dispatch it to the host application?
I'm trying to create an onscreen keyboard, so on every mouseUp event, a corresponding keyboardEvent is created and dispatched to the host application.
Is it even possible to dispatch a keyboard event programatically?

I can dispatch Keyboard Events programatically, and event listener inside my extension works just fine.
var evnt:KeyboardEvent = new KeyboardEvent(KeyboardEvent.KEY_DOWN, true, false, Keyboard.M);
this.dispatchEvent(evnt);
However, the KeyBoardEvent is not propogating up to the host application (Illustrator).
What do I need to do to send it on to the host application?

Dispatching Custom Event

Hello everybody,
Task: I want to enter a message in input text field and
write it in the dynamic using a custom event dispatching.
Solution: I have 2 textfields on the stage.
One textfield is an input text field the other is a dynamic
text field which will server just to display text.
on the flash in the first frame I made this code:
// mb is the instance name of the dynamic text field already
placed on the stage
var messageBoard:MsgBoard = new MsgBoard(mb);
// u1 is the input text field placed on the stage
var user1:UserInput = new UserInput(u1);
Also I wrote 3 very simple classes.
1. UserInput.as // input textfield class that listens to
input and dispatches a custom event
2. MsgEvnt.as // custom event class the instance of which is
dispatched
3. MsgBoard.as // class that listens to the new event and
once it occurs adding event message to the textfield
Problem: Somehow it doesn't work. I actually made it work by
making a listener the same object that dispatches the event. But I
want to understand why it doesn't works the way I showed above. I
browsed a lot of forums and found that all the people use to listen
by the same object that is dispatching. I think it's like talking
with yourself isn't it?
Thanks everybody who will reply and I hope it will help
someone who will read!

your event is dispatched within UserInput scope and MsgBoard
is not within UserInput scope so it's not going to receive that
event. ie, a UserInput instance is not accessible to MsgBoard.
you may have a basic misunderstanding: events that are
dispatched are not like radio signals that are transmitted and
anyone with a listener (radio) can hear them.
when you dispatch an event using actionscript, it is
dispatched by an object (or sometimes by a class) and that event
can only be detected by the dispatching object (or class).

How to dispatch an event on external topic

Hi, I need to know if it is possible to dispatch an event on an external (BEA) Topic instead of ENS server queue.
If yes, any link for docs/example?
My scenario is: JCS 5.0 and Messaging Server 6.3
Thanks in advance

Hi Everyone,
Im currently having a problem with the event notification service for sun java calendar server 6( sun communication suite 5)...i have successfully compiled the sample publisher apub.c and subscriber asub.c..apart from this i haven't done any changes/settings in ics.conf or any other file..when i run the code using the following :
subscriber window:asub.c
./a.out localhost 57997
subscription successfull
publisher window:apub.c
./a.out localhost 57997
apub>bla bla
apub>.
#[root@localhost~]:In the output for apub.c when the apub prompt appears the logic of the code simply has to put whatever we type onto the publisher window(publish) and when i enter '.' on a line by itself the publisher shuts down..*But in my case there is nothing appearing on the subscriber window..there is no notification happening...*
Can i please know if i have missed out any steps..and also if ENS really works.._The thing i want to finally achieve is to somehow get the text/calendar response object containing the event details with the help of ENS_...i'll be grateful if anybody could answer me..
many thanks,
Bharath

How to dispatch an event from the application to the preloader

HI everyone
                 I've been searching everywhere on the net, and as far as it goes I gotten no answer for this. When the application hit the preinitialize phase, I'm calling the loadStyle method. As you can see I will hold the CreationComplete event until I the swf is ready. What I want to do, is to have a second loading bar in the preloader (no problem here) to show the progress of the swf downloaded, hence the StyleEvent.PROGRESS event. I would like to know how can I dispatch that event to the preloader?
///////////////////APPLICATION
              import mx.events.StyleEvent;
            import mx.styles.StyleManager;
            private function loadStyle():void
                    var eventDispatcher:IEventDispatcher = StyleManager.loadStyleDeclarations("cl/elmelej/mangiare/estilo/estilo.swf");
                    eventDispatcher.addEventListener(StyleEvent.COMPLETE, completeHandler);
                    eventDispatcher.addEventListener(StyleEvent.PROGRESS,progreso);
            private function completeHandler(event:StyleEvent):void
                    super.initialized = true;
            private function progreso(event:StyleEvent):void
            override public function set initialized(value:Boolean):void
                // Hold off until the Runtime CSS SWF is done loading.
///////////////////////////////////PRELOADER
virtual public function set preloader(value:Sprite):void
            _preloader = value;
            value.addEventListener(ProgressEvent.PROGRESS, progressHandler);
            value.addEventListener(Event.COMPLETE, completeHandler);
            value.addEventListener(StyleEvent.PROGRESS, progressHandlerCSS);
            value.addEventListener(FlexEvent.INIT_PROGRESS, initProgressHandler);
            value.addEventListener(FlexEvent.INIT_COMPLETE, initCompleteHandler);
As you can see, the preloader is listening to StyleEvent.PROGRESS events, but I cant dispatch that event to the preloader so that it can react to it. I hope you can help me. Thanks for your time and help
Sebastián

Alex,
         Thank you very much for the fast answer, but I'm not an advanced programmer in Flex, so I would need a bit more help from you. I wouldlike you to tell me if it is possible to do what I want to do? and could you be more specific n the information you gave me please?
I think you mean something like this:
private function progreso(event:StyleEvent):void
              (this.systemManager.getChildAt(systemManager.numChildren) as Preloader).getChildAt(XXXXXXXX).dispatchEvent(event)
/////////////////////// (this.systemManager.getChildAt(systemManager.numChildren) as Preloader)) -------->gets the preloader
///////////////////////(this.systemManager.getChildAt(systemManager.numChildren) as Preloader).getChildAt(XXXXXXXX)     -------------> would get the progressbar (only If I have XXXXXvalue)
let me tell you that the method that I posted on the last message was a part of this class:
     public class PreloaderDisplayBase extends Sprite implements IPreloaderDisplay
PreloaderDisplayBase is my Preloader.
I hope you can help me.
Thanks Again
