Re: [flexcoders] updating an item renderer

[claudiu ursica]

The way I see it all the the item renderer is there only for display purposes. 
All the sock retrievals goes in to the provider, rr I mean the model which 
feeds the list provider. If you use binding the list will automatically display 
that changes. Now here-s something we do to avoid object creation... We use an 
array for fast retieval on the element and an array collection for binding ...
In your case that would be translated into something like a stocks collection 
manager which has an stocksArray : Array and stocksAC: ArrayColection. U use an 
id to identify the element in the collection and that is unique ... when a 
stock comes in if it's new u add it, otherwise just update an existing one ... 
The rest is the magic of binding ...

public function addStock(stock : Stock) : void
{
if (this._stocksArray.id + "_"] == null)
{
this._stocksArray[stock.id + "_"] = stock;
this._stocksArrayCollection.addItem(stock);
}
else 
{
Stock(this._stocksArray[stock.id + "_"]).update(stock);
}
}

the update function shoul be in the Stock class and jus update stock 
properties...

Subject: [flexcoders] updating an item renderer


hi list, first post...

i have an architectural question about datatproviders and
itemrenderers that i'll pose with a canonical example.

suppose i have an array of StockInfo objects that is populated by a
3rd party library. each StockInfo object dispatches UPDATE events when
a stock price changes. i want to render the prices in HorizontalList
with a custom renderer.

here's the general application shell:

 = 

http://www.adobe. com/2006/ mxml"
layout="absolute"
applicationComplete ="applicationCom pleteListener( event)">




 = 

i need to wire the stocks array to the list. of course, given that i
already have an array of StockInfo objects, it's tempting to make an
ArrayCollection wrapper that gives direct access to the StockInfo
objects. e.g.,

provider = new ArrayCollection( );
provider.addItem( {stockInfo: someStockInfoObj ect});

then the StockInfoRenderer could register for UPDATE events and redraw
when the event occurs. but i'm hesitant about that approach. if i went
that route,

1) within the StockInfoRenderer, where would i register for the UPDATE
event? in commitProperties( )?
2) within the StockInfoRenderer, where would i *remove* the UPDATE
listener?
3) given that renderers are reused, are there issues with synching, or
with stranded listeners causing memory build-up?

more generally, what's the right way to wire my list to the stocks
array? it feels like i might be forced to handle UPDATE for each
StockInfo object, and write a 'price' variable into a data provider.
e.g., 

provider.getItemAt( i).price = value;
provider.itemUpdate d(provider. getItemAt( i), "price");

seems a shame, given that i already have an array of StockInfo
objects. the above two lines presuppose that i'm going to hunt for the
item index every time a stock price changes. : (

another general question, do i even need the itemUpdate() call, or is
that part automated?

thanks for any advice!

RE: [flexcoders] Re: Sending POST requests to php script??Help

[Tracy Spratt]

You can, but you have to use Actionscript, not declarative mxml.  Build the
request object in an AS function, something like this:

var oRequest:Object = {first:modelName.name.first, last:modelName.name.last,
email:modelName.name.email}

srv2.send(oRequest);

 

and remove the entire  tag.

 

This approach is generally easier to work with because you can debug the
values you are sending to the server.

Re: [flexcoders] static function and getDefinitionByName

[Sefi Ninio]

It has a few private static members, and a few public static getter
functions that manipulate the private members (no arguments on any of the
functions).
Nothing out of the ordinary.

I get the fully qualified class name, and the static getter to be executed -
at run time via XML.
I use the class name to create a Class instance, and then I tried
ClassRef[getter]();

Nothing. When I debug it, the debugger doesn't event break on the breakpoint
in the getter.

[flexcoders] Re: Was feedback on publishing poems, embedding images

[brucewhealton]

In the example I discussed recently, about publishing poems online
using flex, I used images to hold the actual text of the poem.  I
thought initially, not sure why, that I had to use that to ensure the
layout of the text.  Obviously there are ways to use a '\n' to force a
newline.  

However, let's say I kept the use of images to hold the poems.  I used
Accordions that exist within a Panel component, where each Accordion
and Panel component held 5-6 poems or pages (some poems had to span
more than one page, or pane).  Each of the Panels is a custom
component based on the Panel component (which holds an Accordion).
I also have an ApplicationControlBar at the top that selects between
different instancesAccordion instances.  So, the ApplicationControlBar
has Poems 1 - 4 followed by Poems 5-8 and etc. like that, where each
selection, holds a different Panel that holds an Accordion.  When you
are on a slower internet connection, this doesn't look too good.  Each
time you click on a new pane of the Accordion you have to wait a bit
for the next pane to load, because the pane holds an image file.
 
I was thinking that if each custom component, each Panel, could embed
the images but load as an external component then there would be a
wait only when the different groups of poems load, in other words,
when you click on Poems 5-8 to go from reading Poems 1 - 4, the
application would load an external component, perhaps a swc, if I
understand things right.  That reduces the time that the user has to
wait when going from poem 5 to 6 and 6 to 7, or page 2 of poem 6 from
page 1 of poem 6.  Hopefully, I'm explaining this clearly.

How would I compile each custom component into a separate application,
or separate swc component?  and then how do I include each of these
into the main application?

Thanks in advance for any help,
Please let me know if I'm unclear.

[flexcoders] Re: Feedback and ideas re: publishing a collection of poems

[brucewhealton]

I saw this component somewhere that had a poem that scrolled slowly 
automatically, like you would if you read a page and it doesn't all
fit in the window, such as with this window where I am typing this. 
Now, if there was an automatically scrolling feature, it would be
important for a reader to be able to have some control, like scrolling
back to the top, pause scrolling, etc.

So, what would be needed is a pause button, to stop the scrolling, a
start/play button to resume, and a way to manually move up and down,
to scroll up and down.

hi All,

I am facing a weird issue in LCDS 2.6.

There are two unrelated entities A and B, i.e. they dont' have any relationship 
defined in data-management-config.xml
My application is MDI based and consists of multiple mini-apps.

Steps:
1. User opens miniapp for entity A, makes it dirty, don't save it.
2. Then opens minapp for entity B, does an operation which causes B's assembler 
to refill.
   immediately B's assembler complains that B's data is dirty.
This shouldn't happen as A and B don't have any defined relationship .

3. Save dirty entity A
4. miniapp for entity B stops complaining for dirty data.

5. now dirty data in B.
6. dirty an entity in A, save it. B also gets committed to db.

somehow these are getting linked together.

Printed uid of DataService.dataStore for both, it is different.

Any help in this would be appreciated.

regards,
Rajeev

RE: [flexcoders] Compressed swf

[Alex Harui]

The first bytes of a SWF will never be PK.  A SWC will, but not a SWF.

SWFs produced by Flex are compressed, but cannot be de-compressed by ZIP.

Depending on how you built your SWF, there might be different sets of classes 
or classes that will be loaded via RSL and therefore not in the main SWF.

I'd unregister for the last one (when the renderer is recycled and the

[flexcoders] Help with a smarter custom LabelRenderer

[sbeausol]

Hello-

I've been able to successfully implement Ely's Custom LabelRenderer for
my own purposes (Custom LabelRenderer
 ) however I
was hoping to make it smarter.  In my app, I have a Line Chart with my
primary piece of data being modified LineSeries (basically a vertical
line series to plot a spectrum so its a line starting at x,y values and
drawn down to the x-axis) and 3-4 plotseries.  My labelRenderer has been
customized to label points from the the plot series I add.  The label is
a string about 2-3 chars long, however the nature of my lineseries chart
is such that some line ends up intersecting my labels, and some labels
actually overlap making for a relatively cluttered look.  What I was
hoping to do within the labelrenderer is to find out if I have any
points near the point I am labeling, and adjust my labels when needed. 
I played a bit with the findDataPoints function within the chart object,
but I'm not 100% sure what I'm doing and it seems as though if I ever
return and hits they are all from the same series and never include
other series hits.  Am I on the right track?  I am guessing i need to
customize the findAllDatapoints function but I'm not sure where to
start...

Any input is appreciated...

Re: [flexcoders] Re: Can't seem to get Myriad Pro to encode in Flex

[Michael Wills]

Hi Adrian,

Did this ever get worked out?

And by any chance did you publish your swf font to Flash 8? I seem to 
remember the docs saying Flex uses Flash 8 for swf fonts. I'll have to 
look that up to be sure if that's a requirement though.


Oh and Flex can only transcode TTF files so yeah, OTF files are out.

Re: [flexcoders] jQuery for Flex - a Behavior Injection Framework

I like the possibility of using it with Mate/Cairngorm.

So then it would be the decaf versions of mate/cairngorm? :-)

Seriously though this is quite cool.

Some suggestions: 

1) Use a flag in set data so that you don't go through your logic in 
commitProperties that's only relevant when data changes when 
commitProperties is called for other reasons.
2) I don't think you can make a variable bindable by putting [Bindable] 
AFTER the variable (unless you were intending to make your button 
variable bindable on dataChange).
3) There's a lot of overhead in adding and removing children.  Consider 
hiding and showing instead.

RE: [flexcoders] tree control finding patent node

[Jim Hayes]

This actually from a change event, but an itemClicked one is very
similar ...
(It presumes that you use xml as the dataprovider for the tree, and
listen for the event by adding 'change="onTreeChange(event)"' in your
trees attributes )

private function onTreeChange(event:ListEvent):void
{
var targetTree:Tree = event.target as Tree; 

 var item:XML = XML(targetTree.selectedItem);
 
 var theParent:XML = item.parent();

}

It does seem a bit unintuitive to get an XML object, but normally that
works fine for what you're likely to want to do, I've found.

Hope that's enough to be helpful!

[flexcoders] LCDS: Potential LCDS bug - Commit on one DataService(assembler), commits dirty data of another unrelated DataService

[Rajeev Goel]

hi All,

I am facing a weird issue in LCDS 2.6.

There are two unrelated entities A and B, i.e. they dont' have any
relationship defined in data-management-config.xml
My application is MDI based and consists of multiple mini-apps.

Steps:
1. User opens miniapp for entity A, makes it dirty, don't save it.
2. Then opens minapp for entity B, does an operation which causes B's
assembler to refill.
   immediately B's assembler complains that B's data is dirty.
This shouldn't happen as A and B don't have any defined relationship .

3. Save dirty entity A
4. miniapp for entity B stops complaining for dirty data.

5. now dirty data in B.
6. dirty an entity in A, save it. B also gets committed to db.

somehow these are getting linked together.

Printed uid of DataService.dataStore for both, it is different.

Any help in this would be appreciated.

regards,
Rajeev

[flexcoders] Compressed swf

[smitade]

swf files appear to be compressed - headers start with PK. I was
comparing the swf filesizes of different flex frameworks Cairngorm,
Mate, PureMVC, etc and found significant differences. Cairngorm, for
example, was down to 11 KB. How does one compress your swf down to
this size.

[flexcoders] Re: redundancy in custom ItemRenderer

[flexrookie]

ok, new code, this time with IDs on dataProvider items for tracking.
yes, i know there's no direct renderer-to-provider relationship. i now
realize that the extra renderer instance is created for measurment
(according to alex harui). but i'm still looking for an explanation on
the multiple set data and commitProperties() calls.

i am curious, partly from a performance perspective, and partly
because i want to understand how this works so i can slowly become
better at architecting flex apps. code follows. 

StockApp.mxml


http://www.adobe.com/2006/mxml";
layout="absolute"
  applicationComplete="applicationCompleteListener(event)">

  




StockInfoRenderer.as

package {
  import mx.containers.Canvas;
  import mx.controls.Button;
  
  public class StockInfoRenderer extends Canvas {
protected var button:Button;

public function StockInfoRenderer () {
  trace("");
  trace("StockInfoRenderer CONSTRUCTOR CALLED.");
}

override protected function createChildren ():void {
  trace("StockInfoRenderer CREATE CHILDREN CALLED.");
  super.createChildren();
  
  if (button == null) {
button = new Button();
button.width = 100;
  }
  addChild(button);
}

override protected function commitProperties ():void {
  trace("StockInfoRenderer COMMIT PROPERTIES CALLED for ID: " +
data.id);
  super.commitProperties();

  button.label = data.stockInfo.getPrice();
}

override public function set data (value:Object):void {
  super.data = value;
  trace("StockInfoRenderer SET DATA CALLED for ID: " + data.id);
  invalidateProperties()
}
  }
}


StockInfo.as

package {
  import flash.events.Event;
  import flash.events.EventDispatcher;
  import flash.events.TimerEvent;
  import flash.utils.Timer;

  public class StockInfo extends EventDispatcher {
private var t:Timer;

public function StockInfo () {
  t = new Timer(1000);
  t.addEventListener(TimerEvent.TIMER, timerListener);
  t.start();
}

public function timerListener (e:TimerEvent):void {
  dispatchEvent(new Event("UPDATE"));
}

public function getPrice ():Number {
  return Math.floor(Math.random()*1000)/100;
}
  }
}


output

StockInfoRenderer CONSTRUCTOR CALLED.
StockInfoRenderer CREATE CHILDREN CALLED.
StockInfoRenderer SET DATA CALLED for ID: 1
StockInfoRenderer COMMIT PROPERTIES CALLED for ID: 1

[flexcoders] Hand Cursor on Flex Menu

[Parkash]

Hello everyone,

 

I am trying to add hand cursor on Flex menu can anyone guide me how to do
this.

Here is my code snippet.

 

 

reportMenu = Menu.createMenu(null, xmlReportMenu,
false);

//reportMenu = Menu.createMenu(null,
CMMModelLocator.getInstance().reportsMenuXmlData, false);



 
reportMenu.addEventListener(MenuEvent.MENU_SHOW,ReportMenuShowHandle);

 
reportMenu.addEventListener(MenuEvent.MENU_HIDE,ReportMenuHideHandle);




reportMenu.labelField="@label";

reportMenu.iconField ="@icon";

 
reportMenu.addEventListener(MenuEvent.ITEM_CLICK,reportMenuHandler);

 
reportMenu.addEventListener(MenuEvent.ITEM_ROLL_OVER,reportMenuHandlerRollOv
er);



reportMenu.setStyle( "fontFamily" , 'Verdana' );

 

 

I have tried this but failed

 

  reportMenu.usehandCursor = true;

  reportMenu.buttonMode= true;

  reportMenu.mouseChildren = false;

 

 

 

regards

[flexcoders] Re: Binding property of object in dataProvider

[gwangdesign]

Hi Garth,

Thanks very much for the lead. I am currently following the
"anonymous" object advice but would like to investigate more
ObjectProxy approach later once I have more time.

Just another quick question. It seems both approaches entail
serializing objects in Flash Player at client side. Which one would be
better performance wise if I will be dealing with a large collection
of data (say 600-1000 per "page")?

Best regards,

geng

[flexcoders] Rotate a custom Marker icon with Google Maps Flex API

[Jean H. Chandler]

Greetings ladies and gentlemen of Flex,

My name is Jean.  I'm something of a Flex newby, though I've done a few small 
Flex Apps successfully which are in deployment.  Right now I'm trying to do a 
project involving the Google Maps API.

Currently I have the API working in Flex, I'm testing out the use of overlays 
and markers and specifically, trying to rotate some arrow-shaped custom markers 
I put on the map.

>From seeing this example

http://blog.sunild.com/2009/02/custom-google-map-markers-made-easy.html

...of a Flex app with custom markers that rotate, I understand this is possible 
but I don't know how to do it.  I have played around with the Animateproperty 
effect but I couldn't see any way to do it that way, so I tried using the 
rotate effect based on an example I found here:

http://blog.flexexamples.com/2008/02/27/setting-effects-with-actionscript-in-flex/

So far without luck.  I can create code which compiles, and I attempted to 
rotate the icon object, but it doesn't do anything.  My code is posted here:

http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?catid=585&threadid=1428709

I gather it could also be possible using the Degrafa controls but that is yet 
another entire layer of complexity.

Can anyone help?   Is anyone here familiar with using the Google Maps API with 
Flex?

[flexcoders] How to retrive info send as HashMap in ActionScript using blazeds RemoteObject

[yossi.baram]

Hi helper, 
I Have a class in java and one of its properties is: 

private Map upperColumnHeaders; 

public HashMap getUpperColumnHeaders() { 
return upperColumnHeaders; 
} 

public void setUpperColumnHeaders(HashMap 
upperColumnHeaders) { 
this.upperColumnHeaders = upperColumnHeaders; 
} 

UpperlColumnHeader is a bean translated to ActionScript class as well.


I am sending the data by RemoteObject to Flex. 

my identical ActionScript class: 

[RemoteClass(alias="PresentationModel.PresentationModel")] 
public class PresentationModel 
{ 
 // How do I link this Object to UpperlColumnHeader class?  
(.. "column.UpperlColumnHeader" )
 public var upperColumnHeaders:Object; 
} 

I know Map is translated to Object in Flex. 
How do I retrieve all elements from this Object? 
Is my AS is correct? 
remember the key of the map is String and the value is 
UpperlColumnHeader AS class i created. 

Thanks 

Jo 

Re: [flexcoders] Passing parameter to swf

[Adrian Williams]

Hi Chandru,

   This is actually pretty easy...one the swfLoader.source, simply add 
the traditional "?" and "&" tabs to the source with the values you want 
to pass...then in your called swf, you access the passed values via the 
document.parameters.valueName


i.e.

Main App:

var swf:SWFLoader = new SWFLoader();
swf.source = swfFile.swf?label=Login;

swfFile.swf:

button.label = document.parameters.label;

HTH,
Adrian

You should check out this video tutorial
http://www.webkitchen.be/2008/12/12/video-tutorial-make-flex-components-
with-flash-cs4/ .  Note I've tried doing this sort of stuff in CS3 and
the exact same code can sometimes work and other times fail in CS3, and
I do mean the exact same code.  But since creating components in CS4
I've had no issues. Something that didn't work in CS3, I imported to CS4
and it works fine, so use CS4 otherwise you could easily be banging your
head for no reason.

According to labs, it seems to only be available from the Flex 3 SDK.

Re: [flexcoders] Re: image snapshot in flex

[Rob Kunkle]

Err...sorry that was a typo.

I've had trouble sending jpeg images to the server UNLESS they are  
base64 encoded.


I'd like to send the data from the bytearray directly to the server,  
but for some reason it seems that flash is only allowing the first  
four bytes that identify the binary as a jpeg file to be sent. On the  
server side, I just get 4 bytes. So I've resorted to first encoding  
the data in base64, then decoding on the server.


I know this can easily be done with cold fusion, or web orb, but we're  
not using them.

Thanks very much for the link, I've downloaded the code to experiment with.

I have now managed to sort out that my server-side encoder is adding 5
bytes in front of the zipped data that chokes Flex, so that's a help
as well. I can always pull those bytes off before transfer, if
necessary.

Thanks again.
