Re: [flexcoders] Listening for CollectionEvent in custom component

Hello Wesley and others,

I have prepared a simple test case to demo my problem -

My problem is that the CollectionEvent listener isn't fired.

list.dataProvider = x;

list.dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,
xlistChanged);

oh ok thanks, this makes sense.

In that case I probably don't need any events at all,
because I read the XML data over XMLSocket and
assign that data again and again to a variable.

But I'm still perplexed, why do I have
All/Full/Vacant games: 0 in my test code below?

[flexcoders] Listening for CollectionEvent in custom component

[Alexander]

Hello,

I have 2 problems with my custom component (code below), which works ok 
otherwise. It represents a list of games, with up to 3 players. I feed it with 
XML data being pulled from server:

game id=42
  user .
  user .
  user .
/game
game id=47
  user .
/game
game id=56
/game

I'd like to display summary at the top of my component - how many games are 
there in total, how many are full (with 3 users) and how many are vacant aka 
free (less than 3 users). Unfortunately:

1) the CollectionEvent is not fired for some reason. I have to call 
xlistChanged(null) - to at least test the 2)

2) When I call xlistChanged(null), the _full and _free are calculated wrong and 
both contain the string Full/Free 0. I probably call e4x in a wrong way?

[flexcoders] Re: Push verse Poll in Flash Player

[Alexander]

I think it's worth trying, because trying to read
an integer this way won't waste any CPU cycles -
Flash/Flex probably run select() or poll() internally
and just sleep - until anything arrives over the socket.

(Versus trying to pull anything every 30 seconds -
that will cost you CPU and also feel delayed).

And whenever an integer arrives, then you could
use that number to indicate how many records have 
changed at your backend, so that you can use it to 
provide feedback on the progress to the user
while fetching the updated data over HTTP.

Alex

Hello again,

I thought I've found a solution by using 
the List's resize event to change the size 
of its items, but while it works for the 
simple test case listed below, it goes 
into endless loop in my real app with more 
complex layout and I see the traces:

resize list: 0 - 480
resize list: 480 - 480
resize list: 480 - 464
resize list: 464 - 464
resize list: 464 - 480

[flexcoders] Detecting List width from its itemRenderer

[Alexander]

Hello,

I have an itemRenderer for a List displaying
avatars for users in chat rooms - up to 3 of them.
It works ok (code below), but since the List
itself is inside of a HDividedBox and its width
can be changed, I would like to detect this
event and let my itemRenderer to display
bigger avatars (increase their scaleX, scaleY).

How do I detect this event and where can
I read-access the parent List width property?

setting columnWidth and rowHeight doesn't scale the

Hello,

I'd like to have several labels in alternating colors,

Unfortunately this won't compile:

  mx:Label id=_leftTxt[0] color=0x00/
  mx:Label id=_leftTxt[1] color=0x00/
  mx:Label id=_leftTxt[2] color=0x00/

(won't compile either; but it compiles if I change id - text):

  mx:Repeater id=rp dataProvider={[0, 1, 2, 3]}
mx:Label id={'_leftTxt'+String(rp.currentItem)} 
  color={rp.currentIndex % 2 == 0 ? 0x00 : 0xFF}/

In Flash I could just have an array of TextFields:

  for (var i:uint = 0; i  _leftTxt.length; i++) {
_leftTxt[i] = new TextField();

[flexcoders] Creating blinking glow effect

[Alexander]

Hello,

does anybody please have an advice on creating
a repeatedly blinking Glow effect on a button.

Exactly like the example at the Adobe page
http://livedocs.adobe.com/flex/3/langref/mx/effects/Glow.html
but it should run repeatedly - to draw the 
user's attention to a particular button.

I realize, that in ActionScript I probably can create 
a Timer and then call a play() repeatedly on a Glow 
object, whose target member is set to the button,
but maybe there is an easier method in Flex?

[flexcoders] PopUpButton with TileList and custom renderer works, but 2 annoyances

[Alexander Farber]

Hello,

I'm trying to use a PopUpButton with a red/black colored TileList
and it does work, but has 2 minor issues, that I can't figure out.

I've prepared a simple test case listed at the bottom, please review it.

1) For some reason I get numerous warnings:
warning: unable to bind to property 'label' on class 'Object' (class
is not an IEventDispatcher)
warning: unable to bind to property 'label' on class 'Object' (class
is not an IEventDispatcher)
but I don't even know where to look, which label is it?

2) The TileList tl2 has a scrolling issue. I've searched around
(for example: http://forums.adobe.com/message/2939121 )
and it is probably because the itemRenderer is being reused
and I'm making some wrong assumptions... But where?

Thank you for any hints, please try my code below

Regards
Alex

[flexcoders] Changing color of the PopUpButton

[Alexander Farber]

Hello,

I have a working code for displaying red and black entries
in the list of a PopUpButton (depending on the card suit).

However I'm missing the minor last touch: when the user
selects a red entry in the list and I assign its value to the
PopUpButton's label, I don't know how to change label's color.

I've tried several things and searched web...

Here is my code, please try it out and you'll see the problem -

Thank you
Alex

[flexcoders] 2 PopUpButton questions: force opening upwards + red and black item colors

[Alexander]

Hello,

I'm trying to port a bigger project from Flash CS4 to Flex 3
and have a problem that the PopUpButton, that is located
at the right bottom of my app, opens downwards when
I click it and thus is being cut off. Only if I resize the
browser, it will open upwards as actually wanted by me.

I've tried to prepare a simpler test case (s. the code below)
to demonstrate my problem, but can't  reproduce it :-/

Also I would appreciate if someone could reproduce
me a simple trick to render some of the items (card suits)
in red foreground color instead of the default black?
Do I have to create a separate file as an item renderer
(still reading up there... and don't understand yet,
how to specify that file in my menu which I create in AS)
or is there maybe a simpler trick?

Thank you for any hints and below is my test code

Sorry for the double post.

Also the mangled Unicode string below is the 4 card suit characters.

[flexcoders] Flex3: attaching assets from .swf using getDefinitionByName

[Alexander]

Hello,

I'm new to this list and also Flex.

I'm stuck with a probably simple problem, which 
I'd like to demonstrate with a short test case:

Test.mxml:

?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
   layout=absolute
   creationComplete=onCreationComplete();
   mx:Script
  ![CDATA[
  private function onCreationComplete():void
  {
   var sprite:Sprite = new Sprite();
   var g:Graphics = sprite.graphics;

   g.lineStyle(1, 0xFF);
   g.beginFill(0xFF);
   g.drawCircle(100, 100, 20);
   g.endFill();

   spriteHolder.addChild(sprite);

   // XXX stuff below not working
   var suit:String = 'SPADES';
   var mc:MovieClip = new (getDefinitionByName(Symbols.CLUBS) as 
Class);
   spriteHolder.addChild(mc);
  }
  ]]
   /mx:Script
   mx:VBox width=100%
   mx:Button label=1 icon={Symbols.SPADES} /
   mx:Button label=2 icon={Symbols.CLUBS} /
   mx:Button label=3 icon={Symbols.DIAMONDS} /
   mx:Button label=4 icon={Symbols.HEARTS} /
   mx:UIComponent id=spriteHolder width=200 height=200/
   /mx:VBox
/mx:Application

Symbols.as:

package {
   public class Symbols {
   [Embed('../assets/symbols.swf', symbol='spades')]
   public static const SPADES:Class;

   [Embed('../assets/symbols.swf', symbol='clubs')]
   public static const CLUBS:Class;

   [Embed('../assets/symbols.swf', symbol='diamonds')]
   public static const DIAMONDS:Class;

   [Embed('../assets/symbols.swf', symbol='hearts')]
   public static const HEARTS:Class;
   }
}

How could I make the mc appear? Everything else work ok.
(the icons appear at the buttons, there is a red circle,...)

Thank you
Alex

Honestly, nobody can really answer the question of which one is better, as they 
all are built to server a purpose.  As you are going to have to live and 
breathe whichever framework you choose, you really should research them 
yourself and try it out, then you'll know which one you prefer and which one 
works best with your specific project.

I, too, am using Mate. The best part is the lower learning curve and the fact 
that it is completely independent of your code. I use it in all my projects.

Since there is NO Mate code in your Model, Managers, or Views, you can pop the 
framework off at any time and the application will still run. (you just have to 
handle to events). 

Even though I haven't used it, Swiz also has that reputation. Both have been 
referred to as 2nd generation Flex frameworks (verses Caringorm and PureMVC.

Dear Guy,

While I generally see you're point, there are a few flaws in what you're saying:

1. Try saying that to a corporate executive who is expecting your software to 
work in his existing infrastructure and see how far you get.
2. It is a problem in all version of IE anyway, so if you used the garbage 
known as IE 8 you'd still be in the same boat.
3. It's solved anyway by hacking the hell out of the headers when it's IE 6 :) 
(will be posted somewhere online once I've got the solution 100%).

Yes. Drop support for IE6. It has very little market share these days and is 
about the worst browser out there.

Use a little browser detection javascript to tell users of IE6 it's time to 
update to something that isn't so crappy. Firefox, Google Chrome and Safari are 
all far better browsers than any version of IE.

If developers stopped tying themselves in knots trying to work around all IE's 
faults and instead encouraged everyone to install one of the aforementioned 
browsers we'd soon see many of these sorts of problems go away and we could 
concentrate instead on actually developing content.

Re: [flexcoders] MAC : TextInput focus

[Julian Alexander]

I ran into this same issue but with every browser - however it may be different 
for you.  Either way, the handling is simple:

First, the problem is that the SWF file within the browser doesn't have the 
focus.  Within the app your text field has focus, but you'll notice that you 
won't get any keyboard events or anything until you do a fix.

The simplicity of it is that you need to use a bit of javascript to set the 
focus to the swf on page load.  To do this, you modify the index.template.html 
file to have the following javascript function:

 function focusFlash ()
 {
document.getElementById('${application}').focus()
 }

Now you can call that via ExternalInterface.call('focusFlash') on 
CreationComplete or whichever event makes the most sense.

This will then set the focus to the SWF and shld resolve that issue.

ML,
Julian

Re: [flexcoders] Re: byteStream to .txt file

I think it is possible to download via FTP in flex:

http://projects.maliboo.pl/FlexFTP/

and I'm pretty sure that there's no conversion needed to get it back to a text 
file or anything.  I haven't done any downloading via FTP but I've had a Java 
client stream me files plenty of times and it comes out the other end as the 
file.

Re: [flexcoders] Syntax Question

[Julian Alexander]

Dan,

The problem (I assume) is that the object you're getitng back isn't XML.  I was 
using that as an example, but when you use the as operator if the object 
isn't that type it will always return null.

What is your data provider?  Is it an array of objects? XML? It all depends on 
what you're doing.  Either way, it's based on a list.  Getting the selected 
item will give you a generic object that you need to cast to whichever data 
type (actually, you don't have to but it's nicer) at which point you have all 
of the properties accessible and you can grab the same property that the first 
column is bound to.

You can't access the value from the column name - getting the selected value 
will give you the entire row that the datagrid is displaying from which you 
can get the value you're looking for.  In other words, if you have an XMLList 
as your dataProvider, you can do something like:

var myValue:XML = dataGrid.selectedIt em as XML;
var myName:String = myval...@name.

Make sense?

The problem (I assume) is that the object you're getitng back isn't XML.  I 
was using that as an example, but when you use the as operator if the object 
isn't that type it will always return null.

What is your data provider?  Is it an array of objects? XML? It all depends on 
what you're doing.  Either way, it's based on a list.  Getting the selected 
item will give you a generic object that you need to cast to whichever data 
type (actually, you don't have to but it's nicer) at which point you have all 
of the properties accessible and you can grab the same property that the first 
column is bound to.

Julian... Apparently you are wrong?

When I do it with an untyped var I get an object with an XMLList for each grid 
column
   var squat = dataGrid.selectedIt em;

This
var myValue:XML = dataGrid.selectedIt em as XML;
returns null for myValue

Why is it such Rocket Science to get the first value in a column?
Very frustrating for something that should be so simple.

Thanks for the help

You can't access the value from the column name - getting the selected value 
will give you the entire row that the datagrid is displaying from which you 
can get the value you're looking for.  In other words, if you have an XMLList 
as your dataProvider, you can do something like:

var myValue:XML = dataGrid.selectedIt em as XML;
var myName:String = myval...@name.

Make sense?

Re: [flexcoders] Syntax Question

[Julian Alexander]

Alright Dan.. so we're going to solve this.  After this much back-and-forth, 
we've gotta make it work.

So here's the deal:

if you use my statement and squat is just XML, then you're almost there.

It should be something like this

yourObject
nameGZAW08/name
otherPropertyvalue/otherProperty
etc... /
/yourObject

With your variable squat, you can then access a specific property of it by 
saying, for example, squat.name - that will give you the value.  If you want it 
as a string, you can also say squat.name.toString().

Just to clarify earlier, if you had 

yourObject name=GZAW08 etc.../

then you would use squ...@name.

I have a message that, when copied into a text file, is about 750k.  This

Is there a limit to HTTP Request sizes?

Re: [flexcoders] Combo box right-anchor

[Julian Alexander]

Okay, I actually got a bit distracted and didn't end up working on this for the 
last day or so, however after a brief search I did find the solution in the 
archives, however I implemented it slightly differently (it's along the lines 
of what you were saying, Alex):

private function handleOpen (
aEvent:DropDownEvent
   ):void
{
  var myScreenWidth:Number  = Application(Application.application).width;
  var myCombo:cComboBox= aEvent.currentTarget as cComboBox;
  var myCurrentX:Number= localToGlobal(new Point(this.x, this.y)).x;

  if(myCurrentX + myCombo.dropdown.width - 50)  myScreenWidth) {
  myCombo.dropdown.x = myScreenWidth - myCombo.dropdown.width;
  }
}

This is specifically because I don't really care unless it's at the right edge 
of the screen and will be cut off, so only in that case do I do anything.  
cComboBox is my own extended combo box, and as you can tell the function is 
within it with the listener being added in the constructor.

Thanks for the direction!

-Julian

There is no API for this.  You might find an old discussion of

to adjust the scrollRect.

The DG will measure the first item in the dataprovider.  If that
isn’t “typical” you can get bad results.  But first, make sure your custom
renderers to accurately measure.  Lots of folks have problems especially if the
renderer has something in it that word-wraps text.
 
I think you can just set rowHeight to a number that is “typical”
and variableRowHeight will still work.

Subject: [flexcoders] measureHeightOfItem s()
 
  
Dear All,

I have a component that is a composite of a datagrid and an advancedDataGrid -
the datagrid being on top. The top datagrid shows the primary
information, while the bottom grid shows everything grouped (using the grouping
functionality of the AdvancedDataGrid) , however I am having some serious issues
with the sizing of the top grid.

The idea is that it is sized based on the components within it, however it has
the most variables you can possibly get for such a scenario - namely, it has
custom renderers in each case it's used (and it's not the same renderer each
time), variableRowHeight is true - and has to be.

The problem I'm running into is that the measureHeightOfItem s() gives me,
occasionally, grossly inaccurate figures. I get the top grid being twice the
size that it needs to be on occasion.

Does anyone know how to fix this or an alternative method?

 What should I do to vertically position the buttons on the same baseline

 does not work, since HBox   abolishes absolute positioning.

 Hi
 How to block/restrict  undefined value or null value in Lineseries

 The Data point in the Chart is in 0 position of the Axis if the value is

 Please help me .I am relly sturggling to come out from this issue. 3 days

[flexcoders] Position elements with different font size against baseline in HBox

[Alexander Tarelkin]

Hello, flexcoders.
Let's pretend I have the following code:

mx:HBox
mx:Label text=LABEL1 fontSize=10/
mx:Label text=LABEL2 fontSize=12/
/mx:HBox

What should I do to vertically position the buttons on the same baseline
without using padding? Referencing some constraint row from outside the HBox
does not work, since HBox   abolishes absolute positioning.

Thank you,
Alexander Tarelkin

Re: [flexcoders] Flex Compilation takes long time

[Alexander Tarelkin]

I googled on the same subject literally a couple of weeks ago.
Here is the link that shed some light and helped me:
http://stackoverflow.com/questions/33768/any-advice-for-speeding-up-the-compile-time-in-flex-builder-3

What turned out relevant for our projects:
* Slow compile time is most often caused by having large numbers of embedded
resources ([Embed] or @Embed).
We have plenty of them, but the second tip helped much more.
* Go to Project-Properties-Flex Applications. All of the applications
listed are compiled each time.
This one is so evident but no one thought of that. We had 8 applications in
the project, but only two of them were required at a time.

 I was wondering if there is an option or way to automatically return to the

[flexcoders] Sharing DataTransform between series

[Alexander Tarelkin]

Hello,

I am working on an application that displays several series on the same
chart. The series display similar data so they actualy share vertical and
horizontal axes.

I noticed that series.describeData method is invoked twice for each
dimension on any underlying data update. It turnes out that the axes are
involved in several equal DataTransform objects within the chart.
One common created in the CartesianChart, and one for each Serie object.
Each data update leads to describeData invocation in the axes, they in turn
call describeData on the registered datatransforms, the datatransforms call
describeData on each IChartElement.

Thus, each serie is contained in two dataTransforms: CartesianCharts' one
and the Serie's own one.

DataTransform object does not contain any state, so I wanted to reuse the
chart's datatransform for all the series. Each Serie implements
IChartElement so it implies passing in an external DataTransform.

But, it turns out that the implementation of each series (Line, HLOC, Area)
contains the following code in commitProperties method:

dataTransform.elements = [this];

Moreover, the implementation of CartesianDataCanvas contains the code as
well.

Is there any reason why I should not want to reuse the same DataTransform or
it is a bug?

P.S.
As a hack, I certainly can override the commitProperties and return the
thrown out elements back, or even set elements array to an empty one and
communicate over the CartesianChart's datatransform. I just wonder why it is
as it is.

I am using Flex 3.3.0.

Re: [flexcoders] Memory Leak and SuperImage

[Alexander Baetz]

I tried to debug it with the flex builder profiler, but i dont quite 
undertstand the outputs there.

There aren't to many instance of my classes out there. Mostly one or 
two more than visible. my guess is that the garbage collector didnt 
collect them in time for the snapshot.
what worries me are more than 5000 instances of Function and nearly 
the same number of Object. Is this normal? Together these two groups 
need more than 60% of my memory.

If i read the profiler right, most of the objects are created in a 
function where i create a tooltip.

I still hope someone has an idea.

Greetings,
Alexander

CODE:

var pt:Point = new Point(event.currentTarget.x, event.currentTarget.y);
pt = event.currentTarget.localToGlobal(pt);

var curX:Number = pt.x;
var curY:Number = pt.y + event.currentTarget.height;
   
tip =  new SkillTooltip();
tip.Skill = mySkill;
   
if (curX + tip.width  Application.application.width) {
curX = Application.application.width - tip.width;
}
tip.x = curX;
tip.y = curY;

[flexcoders] How to Embed an Application that Supports Deep-Linking?

[Alexander Baetz]

Hi,

for Training i developed an application that uses the Flex 3 
Deeplinking-Mechanism. I used the Flex Builder and everything Works 
perfect when i open the html-file, the flex builder creates.

Now i tried to embed the application into an existing page (for example 
www.mydomain.de/myapp.html . I placed the application at 
www.myotherdomain.de/testapp/ and started trying.
Since i don't know much about JavaScript i tried the 
copy-paste-Approach. Copy the content of the generated html-file, fix 
all links, check all links, hope it works.

Well, all links work, i hoped and it didn't.
No action inside my app changes the url inside the browser.
No parameters attached to the url in the prowser affect the application.

My current Testembed is added as an attachment. Everything beside 
testapp_embed.txt was generated by the flex builder.


How can (or should) i use a flex application from another domain and 
make deeplinking still work?

I hope somebody out there can help me.

Alexander

[flexcoders] Event result listener problem

I am using a component as a popup, and i create 2 instanced of it. The
component edits a users information. If I open two different popups

I guess, how can i route the event result to the correct popup?

[flexcoders] Equivalent of FMS server side object in LC Data services

[Alexander Tsoukias]

So, if I was to create a server side shared object with Flash Media
Server i would have my online users in a shared object, then another
server shared object with all the chat users etc...

If i was to do this with LCDS (Live Cycle Data Services) - again using

Currently i use Data Services which stored the data in a database. In
FMS i guess it just keeps it in memory.

Any idea?

[flexcoders] Remoting using RTMP protocol

[Alexander Tsoukias]

I am trying to find out if there is a way to do same logic as when

In my logic, i would just create a new destination in

Would this work? If not, can this be at all done?

 The real question is - does it move you in the right direction.
  Architecturally, (long) RemoteObject call is a one-way-at-a-time
road with
 typical congestions including latency, inability to detect lost
 packages/dups/out of sequence. RTMP is usually 2 pairs of 2-way sockets
 (Publishing and Subscriptions), using acknowledgements on each
side rather
 then responses. Blocking model of request/response over
non-blocking IO
 model of RTMP will most likely put a lot of pressure on the resource
 consumption and performance. By using Publisher/Subscriber objects
as higher
 level tunnels you can solve much more of typical problems of RIA
apps.To add
 by-directional (pull and push) RemoteObject functionality to the
RTMP you
 have to start with endpoints - basically keeping track of
 messageId/CorrelationIds as standard functionality of RemoteObject with
 standard timeouts will not suffice. Deciding if you want code
distributed
 between endpoint and adapter is really up to you - but keeping endpoints
 unchanged is not really an option, and then you have to decide on
number of
 places to maintain the code.
 As far as adding remoting destinations - it is trivial from messaging as
 well - you can get implementation from BlazeDS
 sources
C:\blazeds-source\modules\remoting\src\java\flex\messaging\services\remoting\adapters\JavaAdapter).
 It would go like this (optimization removed for brevity):
 
 public Object invoke(Message message){
 RemotingDestination remotingDestination =
 (RemotingDestination)getDestination();
 RemotingMessage remotingMessage = (RemotingMessage)message;
 FactoryInstance factoryInstance =
 remotingDestination.getFactoryInstance();
 
 // We don't allow the client to specify the source for
 // Java based services.
 String className = factoryInstance.getSource();
 remotingMessage.setSource(className);

[flexcoders] itemRenderer on TileList question

[Alexander Tsoukias]

I am using an itemRenderer and in that renderer i am calling the
init() method on creationComplete event. 

The List's dataprovider is an ArrayCollection from LCDS rtmp and i
notice that the init() function does not get called everytime a new
item is added (even though the new item does display on the TileList
as a new row.

So I guess my question is, how can i EVERYTIME call a function in my
itemRenderer component?

thanks,
Alexander

 Flex recycles itemRenderers, so it does not create 1 per item in your 
 data provider.  Instead it creates enough renderer objects to display 
 the data, then calls the setter of the data property set 
 data(value:Object) on those existing renderers as things change 
 (scroll, etc.)  So, the way you handle this is to override the set 
 data(value:Object) method in your renderer... the object you are passed 
 as a parameter will be an item from your data provider.

[flexcoders] Error: Unknown Property: 'constructor'. when using LCDS

[Alexander Tsoukias]

The fill method works great using RTMP and it fills a datagrid.

When i make the datagrid editable and change a value, It returns this
error: Error: Unknown Property: 'constructor'.

The backend is connected with coldfusion CFCs. Again the fill method
works great.

Thanks,

[flexcoders] Coldfusion changes not applied when using LCDS

[Alexander Tsoukias]

Situation:

Flex app connects using Data Services (RTMP) and uses
coldfusion as the backend (CFC). Everything works fine.

I then edit the coldfusion DAOs CFC code and on purpose cause
it to throw an error.

The app continues to work as if it doesn't even use the CFC files again.

Only when i reboot the CF server the changes apply.

[flexcoders] Flex Data Services (of LiveCycle Data Services)

[Alexander Tsoukias]

I am trying to create a multiplayer game, in which at first i need to
show a tables list of available seats.

Each table, should be a new destination on FDS server? or am i missing
something here?

If thats the case, how do i automatically create and delete destinations?

(I'm using RTMP - if I was using Flash Media Server, I would create
server side shared objects).

Thanks,
Alexander

[flexcoders] Re: Flex Data Services (of LiveCycle Data Services)

[Alexander Tsoukias]

This really does sound what needs to be done (in theory). Practically
how would i go about doing this?

Is there some documentation I can reference? I'm new to this topic
(even tho I own the licenses) just trying to make some good use of them.

With Flash Media Server i'm assuming this would be done using server
side Shared Objects?

Thanks
Alexander

 Take a look at the subtopics feature of the Consumer or the
 MultiTopicConsumer if you want to receive multiple subscriptions from a
 single message stream.   You'd have one destination for the seats as a
 whole and probably a separate subtopics for each seat.  If you need to
 route messages to players individually, you could have a another
 destination for players and a subtopic based on the user's session or
 user id.   Subtopics are created lazily the first time someone
 subscribes to them and are removed when the last user unsubscribes.
 
  
 
 Actually, this type of thing is probably easier to do using data
 management since that will do all of the subscriptions for you.   In
 that case, you'd do a fill to get the list of seats (which would then be
 sync'd with the server so as new seats come and go the client would
 automatically be updated).   Once you select a seat you'd do a query to
 get the view of data for that seat... again that is sync'd automatically
 with the server if you leave autoSyncEnabled=true on the DataService.
 Each user could also create records for their per-user info which other
 users might share by getting a reference to... maybe the seat would have
 a reference to public view of the users at that table.

 I think that's accurate. Some of the simpler operations are able to

 It does depend on usage. For high resolution photo editing - and  
 relatively accurate color work, it's best to do that outside of AS.  
 Things like a 'filmic' sepia conversion isn't possible with a simple  
 transformation that Flash can handle (not without per-pixel  
 operations that is).
 
 That said, with Hydra and the new advancements Adobe is making to get  
 Photoshop online marketable, I think we'll be seeing some pretty nice  
 capabilities in the Player in the near future.
 
 good luck on your project if you're heading down that road. :)

[flexcoders] Re: Picnik photo functions/features R

[Alexander Tsoukias]

Troy, your response has been the most reasonable, their preview is
instant, and if there were sending it back to server and bring it back
again so fast they would be the next bill gates.

 If you get a bitmap as a byte array you can scan through it and apply
 all sorts of traditional per-pixel manipulations. Sure, maybe not
 real-time in a video game sense (multiple frames per second), but
 certainly real-time in the web app sense (a few seconds, about like
 a network request).

In terms of applying traditional per-pixel manipulations - can you be
more specific in possibly which and how? As much as you can tell.

 I believe a majority of the image processing is done on the server

 Some transformations may be done in AS, but it would not make sense  
 in the general case to do so. Especially with complex transformations  
 that may require per-pixel operations - AS is exceedingly slow at that.
 
 In my experience it's faster to push a quick image transformation  
 matrix or color matrix (or other image edit) to the server and have  
 GDI++, ImageMagik, PIL or one of the many imaging libraries make the  
 modification and send back a proxy.
