[flexcoders] Relayout component

[flexcoders] dispatchEvent import

[flexcoders] Simple sum operation issue

v += 1192.33;
textInput.text = v.toString();

Re: [flexcoders] Re: Properly remove children
I have some doubt about weak references at eventListener. When I add a eventListener with weak reference true, the object don't get a point/reference to it but what happens with eventListener array after removing this object. This array don't has the reference for garbage collect, so the garbage collect could collect it, but this object was never removed from this eventListner array, wasn't it? That's my question. Is this object removed from eventlistener array when weak reference is true? Is it feasible to implement it in pure action script or It is a voodoo feature for compiler?

I have a container that I am adding different forms to at the run time. These forms are all based on the same class though. So, before I add a new form I am removing current form using: container.removeAllChildren(); each form when created is adding a custom event listener to a parent - the container. When a custom event is triggered every form that was created (regardless that it was removed after) gets this custom event to handle. When you listen for an event on one of your ancestors, you usually want to use a weak reference (the last parameter to addEventListener). That's because your parent doesn't know you're listening on it, so when you've been removed and discarded, you'll still be around because of the event listener. Manish

Re: [flexcoders] Best practice for calling asynchronous functions?
Mark,
I've used to the same approach you describe but I didn't implemet
failureFunc. This facade, in my case, detect a failure and display
a message error. This approach take an advantage that you don't take
care any more for failures and it will always be treat in the same way.
This is a example method in my facade
public function formDeleteAccount( listener: Function ): Operation
To call this method you can use
formDeleteAccount( handler ).send( params )
The send method return a AsyncToken and you can add more listener
or put other params token for handler function.
There is other methods like it:
public function filterByText( listener: Function, text: String ): AsyncToken
In this case, we use the compiler to force the correct params. I like
this second approach
and we will convert all the code to use it.
If you have an interesting, I can send you all the code. But believe,
I don't know if it is the
best practice, but, for my problem, it run very well.

In my app, I make a wide variety of XML-RPC calls. Now, to avoid having to
add/remove listeners all over the place, I've created a class (facade?) with
functions like:
function save(xml:XML, successFunc:Function, failureFunc:Function):void;
function load(id:String, successFunc:Function, failureFunc:Function):void;
Note, the class' state does not change when any of these functions are
called.
The class makes the necessary XML-RPC call and listens to the appropriate
events before calling the relevant success or failure function. The class
guarantees that either the successFunc or the failureFunc will be called at
some point (but never both).
This makes my calling code very neat:
save(myXML, function(id:String):void {
Alert.show(Successfully saved XML using id: + id);
// now do the next step
}, function(msg:String):void {
Alert.show(Failed to save because: + msg);
// now rollback
});
One obvious drawback of this is that its not so easy to add multiple
listeners to, say, the save operation. But, in my situation, I never need
to.
What say you all - good or bad practice?

Subject: [flexcoders] Set up style for TextField
Hi,
I extended a textinput component to show other relationed text based
on input user.
It is a kind of personal component for application interface rules. I
could show this
text in other component behind it, but the design and usability was not so
good.
The snipet code above show how I added other text (TextField) behind
TextInput:
private function addAccountText(): void {
this.pAccountTextField = new TextField();
this.pAccountTextField.width = this.width * 65 / 100;
this.pAccountTextField.height = this.height;
this.pAccountTextField.x = this.width-this.pAccountTextField.width;
this.pAccountTextField.y = 0;
this.addChild( this.pAccountTextField );
this.setStyle( 'paddingRight', this.pAccountTextField.width + 5 );
}
The only problem about this code is text format.
Is is not the same format as textinput componente inheritance.
How could I apply the same format into TextField?
I've tried the following lines with no success:
this.pAccountTextField.styleSheet = this.textField.styleSheet;
this.pAccountTextField.setTextFormat( this.textField.getTextFormat() );
Any tips?
Regards

[flexcoders] How to get availability memory
Hi, Is there any way to get availability amount of memory? I only be able to get amount of memory in using by totalMemory property of System class. -- Marco Catunda
Re: [flexcoders] Detect a databinding
Hi Jules, Yes I could separate IList for each view, but in this approach I don't share common data, so the memory will increase without needness. I don't know about performance... I thought ICollectionView (ArrayCollection) for pageaable solution too complex. All of this complex is for local sort and filter features but when We work with remote data pageable, all this nice feature should be implement in server side not in local client side, so there is no worth for remote pageable data. As soon as I have time I will build a short example using this solution and send to you for appreciate. Perhaps, you can have a good idea to improve in this solution. :) Thanks On Wed, Dec 3, 2008 at 8:09 AM, Jules Suggate [EMAIL PROTECTED] wrote: Hey Marco, Could you use a separate IList for each view?

[flexcoders] Store local data
Hi, Is there any way to store local data using Flash Player? I've just seen using AIR. I would like to use it for cache solution. -- Marco Catunda
Re: [flexcoders] Store local data
The kind of data is a dataprovider with a lot of records (500 - 2000). The shared objects don't store many datas. :( Let me explain my problem. I have a screen which user have to input data very fast. It is a kind of POS (Point of Sale). The input text, with autosuggest approach, in this screen, is searching data into dataprovider using memory search. If I implement server search for this autosuggest the latency of this approach won't be accept for input data very fast. Until 2.000 records I guess no problem, but If It will be more, I will have a problem. The AIR has a SQL local data store.

Re: [flexcoders] Store local data
Peter, I've implemented exactly as you said, put the content when the application starts. But the problem is amount of data. If It is larger the memory will be out of. The solution of cache XML in the user's browser has the same memory problem for larger data. I'm praing for that data not become larger... It's my hope right now. Thanks I appreciate your help.

Have you considered pulling the auto suggest content in when the application starts and / or in the background? The only other option that comes to mind is have the server page generate an XML document and have that downloaded in to the users browser cache maybe and pull the data from there? Depending on how often that data changes you could have the server generate the XML document at intervals or when the application is loaded perhaps, I think a server should be able to handle the load depending on the amount of users at any given time.

Hello all,
I have been unable to figure out why something simple is not
happening in a form of mine. I have a form that does successfully
take the user input and email it to us. However, for some reason, the
Alert button that should give the user feedback is not working. It
just hangs there when the user clicks on the submit button.
I will need to share the code to get help with this. It is
very basic and it does send the email message. I'll trim off
extraneous appearance code that is not related to the actual logic of

If anyone knows php how would I send a message from the php form
