Re: [flexcoders] Re: image snapshot in flex
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.

Can the data not be passed simply as a ByteArray instead of a base64

the Adobe documentation for URLRequest:
-
data property
An object containing data to be transmitted with the URL request.
This property is used with the method property. In Adobe AIR, data
is sent when any HTTP
method other than GET is used. In Flash Player, data is set when the
POST HTTP method is
used.
The URLRequest API offers binary POST support and support for
URL-encoded variables,
as well as support for strings. The data object can be a ByteArray,
URLVariables, or String
object.
The way in which the data is used depends on the type of object
used:
If the object is a ByteArray object, the binary data of the
ByteArray object is used as POST
data. For GET, data of ByteArray type is not supported.

My problem is that I am also deficient in my experience with

to decode a byte array there, but this is how I send the byte array

var request:URLRequest = new URLRequest(imgServURL);
request.data =
imageByteArray;

[flexcoders] Rotate a custom Marker icon with Google Maps Flex API
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=585threadid=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? D.

Thanks very much for the lead. I am currently following the

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)?

If the point of your question is that you are starting with

The other alternative is not to use an anonymous object, but to
create a concrete class for the tasks:
class Task {
[Bindable] public var label:String;
}
Ultimately this way is better for several reasons. (Note that as
shown the mxml compiler will have to rewrite the class to implement

You assign a dataProvider(StockInfo) to the List, which results in item renderers being instantiated. Note, do not use an Array as a dataProvider, use ArrayCollection. When the underlying item changes, the framework calls the renderer's set data method(setter). When any pending changes are done, the framework calls commitProperties. Well, sort of. If a property of an object that's stored in an ArrayCollection changes, the ArrayCollection has no idea, and hence the List will not call setData(). You could potentially set up your itemRenderers to register/unregister for these events in the set data() override for your renderer. But that means your renderer can only ever be used to render this type of object. That's not necessarily a bad thing, but I try to keep my renderers barefoot and pregnant if you know what I mean. So my approach would be to have a manager that contains an ArrayCollection of StockInfo objects as one of its public properties. Bind the dataProvider on your HorizontalList to that public property. I'd probably limit that to read-only by just using a getter on it. Make sure your manager component takes care of all of the adding and deleting of StockInfos into the AC, so it can register for your change events on all items that are currently stored there and unregister for them once they're gone. Then when the manager gets the event, calls itemUpdated on whichever SockInfo changed, and the HorizontalList will update normally with no more special effort on your part. HTH; Amy

[flexcoders] LCDS: Potential LCDS bug - Commit on one DataService(assembler), commits dirty data of another unrelated DataService
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] tree control finding patent node
Hi, in a tree control if a leaf node if clicked how do I find out which folder it belongs to or which node is its parent? Regards...
RE: [flexcoders] tree control finding patent node
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] Help with a smarter custom LabelRenderer
Hello-
I've been able to successfully implement Ely's Custom LabelRenderer for
my own purposes (Custom LabelRenderer
http://www.quietlyscheming.com/blog/charts/chart-sampler/ ) 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] Compressed swf
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.

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.

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

Re: [flexcoders] static function and getDefinitionByName
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. On Tue, Mar 3, 2009 at 12:58 AM, Alex Harui aha...@adobe.com wrote: What does the class definition look like?

RE: [flexcoders] Re: Sending POST requests to php script??Help
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 mx:request/ tag.
This approach is generally easier to work with because you can debug the
values you are sending to the server.

I don't want to bind the object. The {...} was suggested in a
previous post. I don't understand why I can't reference the object's
value in the HTTPService request.

I CAN access the flex object at run-time. And it need not be bindable.
For example:
Alert.show(modelName.name.first,title=modelName.name.first Value);
Correctly displays the modelName.name.first value. However, when I
access the same object in the HTTPService request, I can not access
the objects value. I don't know what the problem is.
This problem is driving me nuts.

Re: [flexcoders] updating an item renderer
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:
=
?xml version=1.0 encoding=utf- 8?
mx:Application xmlns:mx=http://www.adobe. com/2006/ mxml
layout=absolute
applicationComplete =applicationCom pleteListener( event)
mx:Script
![CDATA[
import mx.controls. HorizontalList;
import mx.events.FlexEvent ;
import mx.core.ClassFactor y;
protected var list:HorizontalList ;
protected var stocks:Array;
protected function applicationComplete Listener (e:FlexEvent) :void {
// Stock data (hardcoded for the example)
stocks = [new StockInfo()] ;
// UI
list = new HorizontalList( );
list.width = 400;
list.height = 100;
list.itemRenderer = new ClassFactory( StockInfoRendere r);
addChild(list) ;
}
]]
/mx:Script
/mx:Application
=
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!
