You might approach it something like this: 1. start with your collection of filenames 2. enumerate over them, creating a loader object for each 3. add an event listener to each loader so you know when it is done 4. when you get notification that an image is loaded, increment some tally 5. when the tally equals the length of your original collection, you are good to go Someone else may be able to elucidate the finer points of using loaders and how to then use the loaded content in other controls.

The numer of Tabs and controls will vary depending on criteria (reading from an XML). --- Sample xml data below - Tab tabid=App_Form_01_Tab_02 name=Tab 2 label=Product Information taborder=2 Section sectionid=App_Form_01_Tab_02_Sec_01 name=Contract orderontab=1 Attrtype name=SingleLineofText defval=This is single line text maxchar=35 maxlines=1 inputtype=TextInput attrlabel=Attribute 1/Attrtype Attrtype name=MultipleLinesofText defval=This is multi line text maxchar= maxlines=4 inputtype=TextArea attrlabel=Attribute 2/Attrtype /Section /Tab Tab tabid=App_Form_01_Tab_03 name=Tab 2 label=New Tab taborder=3 Section sectionid=App_Form_01_Tab_02_Sec_01 name=Contract orderontab=1 Attrtype name=SingleLineofText defval=This is single line text maxchar=35 maxlines=1 inputtype=TextInput attrlabel=Attribute 1/Attrtype /Section /Tab I tried developing the above UI by creating custom actionscript components by extending existing UI components such as TabNavigator/VBox and added children at each stage until I reached the actual form control info using which I am creating the controls.

RE: [flexcoders] Tree: Resetting openItems after dataProvider change
Yes, Hank's solutionsis what I would do. Further, when you say ...Flex 2 tree control limits direct access to nodes..., you make me suspect you are making a conceptual mistake. With data-driven controls, you never directly access the controls themselves. Rather, you work with the dataProvider, to which you have full access. So in your case, you would have the unique id on each element(XML object/node) in your XMLListCollection, and you would store the open nodes in some list. I think an associative array(hash table) would be the most efficient. The function to open those nodes would need to be recursive. When your recursive function matches a node in the associative array, you would need to climb back up the tree, parent by parent, opening each node as you go, till you reach an alrady open node. Might be a bit more compilcated than that, since you want to reach the end of a recursion branch before you stop searching.

State FooB has 2 FormItems, one with a ComboBox, and the other with a TextInput and is also based on the above base state, and is also added as the last children of myForm. I change the state depending on the input in the 3rd TextInput in the base state.

[flexcoders] How to Use the Value of a Checkbox in a Component
Hello, I'm very new to Flex so please excuse my newbie question if it
seems a bit dumb...but here is my situation: I have a Flex
application - let's call the main application file 'Main.mxml' - I have
a component file - let's call it 'MyComp.mxml'. Within
the 'MyComp.mxml' file I have an mx:CheckBox id=chkBox1 object. I
am calling the MyComp component from the Main.mxml file. The user can
check or uncheck this checkbox and then click on a 'Submit' button that
is defined in the Main.mxml file, which will then fire off the
processing logic. All I want to do in the processing logic is to be
able to examine whether the user has checked the chkBox1 checkbox or
not, so that I can pass that value from the Main.mxml file to a web
service. But when I try to do a simple binding {chkBox1.selected} from
within the Main.mxml file, the error I get is '1120: Access of
undefined property chkBox1.' Can anyone help?

[flexcoders] garbage collecting and local variables
Hi everyone,
My name is Jorge Maiquez, and this is my first post here. My question
relates to the AVM2 garbage collection mechanism. I have asked it
elsewhere but have not gotten a response. Here it goes:
From the AS3 docs:
Objects with registered event listeners are not automatically removed
from memory because the garbage collector does not remove objects that
still have references.
How does this work with local (function) variables to which we attach
event listeners? For example, if we have a class with these methods:
private function setEvents():void {
var _ldr : URLLoader = new URLLoader();
_ldr.addEventListener(Event.COMPLETE, onComplete); }
private function onComplete(e:Event):void {
// _ldr is referenced by e.target
}
Is it a bad idea to make _ldr a local variable?
Afaik, local variables are marked for garbage collection after the
parent method has executed, right? But _ldr is an object with a
registered event listener.
Does this mean that _ldr will never be garbage collected? So if I call
the setEvents method a 1000 times, will I have a 1000 _ldr's kicking
around in memory?
Thanks in advance!
-Jorge
Re: [flexcoders] Tree: Resetting openItems after dataProvider change
Actually, Tracy, I dont think you need to do all of this work. The openItems field of the tree does it for you. So you just need to go through the openItems array of nodes and gather all the item IDs that I described in the prior email. To reopen them later, you just use the an e4x function (I forget the syntax but I can look if necessary) to find all the items in the dataprovider that have the given ID. You then open each one of these nodes. Hank On 12/26/06, Tracy Spratt [EMAIL PROTECTED] wrote: Yes, Hank's solutionsis what I would do.

RE: [flexcoders] How to Use the Value of a Checkbox in a Component
There are several ways to do this. The simplest to code is to directly
access your control by dottting down through the component dom. If your
component is directly referenced by id in the main app you can do:
myCompId.chkBox1.selected.
This might not be the best term solution, though, depending on how many
such references you will have and how flexible and reusable you want
your component to be.
The most loosely coupled design would be to have your component
dispatch a custom event when a control is interacted with, and listen
for that event in the parent. Extending the Event object will let you
include any data you want in the event, such as the states and values of
the controls.
Between those extremes are other options, such as passing references to
the main app into the component, which can then update a data
structure(like an array or associative array) in the main app.
As I said there are lots of options. Its ok to take the simple code
path to start with. Just keep in mind longer term best practices.

[flexcoders] Help with custom button?
Hi folks,
I am trying to create a custom button in AS3 using the Flex 2 SDK. It is
pretty simple; I just want it to be a wedge shape that I can rotate to
point in an arbitrary direction. My code is attached below, but I'm
stuck on two issues:
1. Making it behave as regular buttons do in terms of mouse-over and
mouse-down behavior (i.e. draw it differently in these cases).
2. Currently, when I rotate it, e.g.:
Arrow_Button height=12 width=12 rotation=45
click=Alert.show('hello');/
it rotates around its 0,0 point (which is the upper left corner),
causing it to swing out of the area where Flash thinks it is, messing
up the layout.
I've been wandering through the docs and Google all afternoon, but I
haven't figured these things out.
Any help or pointers to appropriate documentation would be very much
appreciated.
TIA,
Reid
// This class defines a button which looks like an arrow. It points up
// and relies on the rotation property to be pointed in the right
// direction.

[flexcoders] Determining VDividedBox heights
I'm trying to remember the height at which someone sets a vertically divided section. I am using a VDividedBox and have set a listener to the dividerRelease event. When I get in there I can trace out the height of the top component within the VDividedBox but it gives me the pre-resized value. I am assuming that the drop event happens before the redraw. Okay, not a shock. But what is confusing is that the VDividedBox object itself doesn't seem to have any getters nor properties for the size of the two boxes it is in control of. Am I missing something? I believe I can use the delta property on the event that is thrown and add that to the pre-resized value of the top box. I'm thinking that is a workaround, but am I missing something? Thanks

[flexcoders] Loading Flash 8 swfs into Flex 2 -- Running into _root issues
Hello all, I am creating a portfolio application using Flex 2. In the app, I am loading a number of swfs into the portfolio using a SWFLoader. These swfs were created using Flash 4 through Flash 8 over a number of years. In a few of the swfs, the author has, clearly, made reference to the _root variable from within Flash. When I load the swf files and run them, these calls to _root are causing some serious issues at the Flex Root level. When _root.play() is called from the loaded swf, for example, it causes the entire flex app to choke (and, subsequently, does not trigger the play at the Flash level). Can anyone help me understand how I can force the swf-loader to lock the root of the contained swf? I've been all over the docs and nothing is jumping out at me -- all of the roots on the swf-loader, stage and application are read-only. All of the loader and loader-info variables are read-only as well. I *DO NOT* have access to the Flash source files, so simply adding _lockroot=true to the swf source files is not an option. Any help would be greatly appreciated!

[flexcoders] What's the best approach here (Associative arrays, dynamic classes, etc...)?
Hi all,
Here's what I am trying to do. I have an object that I
get from the server (currently via XmlRpc but that
doesn't really matter). It's an Object. I want to convert
it into a data structure on the client side for easier
manipulation. If I do something liek
class Foo {
var prop1:String;
...
}
then I could use code completion to refer to properties
of an instance of Foo. (I am lazy, and sometimes it's hard
to remember what properties are called). But on the downside,
in order to marshal/unmarshal this object into the raw
object, I need to know these properties. On the other hand
if I make Foo dynamic, and make the property names into constants,
I could use code completion in a bit more unwieldy way:
foo[Foo.prop1] = 'xxx'
and can also iterate through all these properties which is very
convenient for this marshaling/unmarshaling business.
Is there something that would let me combine the best of both
worlds?
Re: [flexcoders] Determining VDividedBox heights
If you want to get the height of children of any container including boxes, you are going to need to look at the size of the children themselves. So if you want the top box in your example, it would be vbox.getChildAt(0).height. However, I do believe that on dividerRelease the child would not have been resized yet (i think it will be resized during vbox.updateDisplayList()). You could try looking for other events to listen to on either the box or the children, but my guess is that the way you're doing it is the best you are going to find.

[flexcoders] MVC Concepts in Flex 2
I am reading the book, Advanced Actionscript 3 with Design Patterns, and must confess that I've never truly followed proper OOD/OOP in writing my Flash 8 web apps. But, now that I'm doing my first Flex 2 web app, I figured I really should do this the right way by implementing a proper MVC design. Separating out the model portion was no problem. I'm properly programming to Interfaces, defining abstract classes to be inherited by the concrete classes, etc. It's completely unaware of the view and controller. So, this part is fine. The question I have, which really isn't addressed in the above- mentioned book, is how to properly design the controller and view when you're not completely creating the view via ActionScript. I mean, it's easy to see how the distinctions when you do as they do in the book and extend the Sprite class and draw the entire view yourself. But, what about when the bulk of your view is defined in an mxml document? If anyone has a good sample flex 2 project they would be willing to share where I could see how you did it, that would be great. Ron

[flexcoders] Problems when using the FlexSessionListener interface to detect when client drop
I'm working on a client/server app where we implement the FlexSessionListener interface to detect when a user closes the browser window so that we can clean up the data on the server. I have found some shortcomings with this approach, but the biggest one seems to be that the sessionDestroy event occasionally fire even when the client doesn't close the browser. It seems to occur when the client is inactive for a certain amount of time, but there is no consistency in this. Can anyone suggest another way to detect when users close their browser? Or perhaps discuss instances when they have observed similar behavior with the FlexSessionListener? Thanks
[flexcoders] Re: MVC Concepts in Flex 2
Ron, when creating your views, you can use MXML with no problem. Take a look at the Cairngorm framework at Adobe Labs (http://labs.adobe.com/wiki/index.php/Cairngorm). They routinely use mxml to create their views and attach ActionScript view helpers to their mxml files. Common uses of this include doing all of the visual layout in the view while having the real code working in the helper. So, for example, the button click would call the buttonClick method in the viewHelper. Hope that helps. --- In flexcoders@yahoogroups.com, rd_grimes [EMAIL PROTECTED] wrote: I am reading the book, Advanced Actionscript 3 with Design Patterns, and must confess that I've never truly followed proper OOD/OOP in writing my Flash 8 web apps.

[flexcoders] setTimeout in flex 2.0
I'm confused on how to use setTimeout
i have a function that i need to wait 500 milliseconds to call...
var aVars:Array = [lat, lng, zoom];
trace(aVars); //39,-105,6
var my_timedFunction:uint = setTimeout(manipulateMap,500,aVars);
public function manipulateMap(lat:Number,lng:Number,zoom:Number):void{
u = new URLRequest(javascript:map.setCenter(new GLatLng( + lat + ','
+ lng + '),' + zoom +));
navigateToURL(u,_self);
}
this makes everything come to a screeching hault, and it tells me i
have an invalid number of arguments, it wants 3 arguments but says
only one is passed
anyone have an example of passing arguments with setTimeout?
ps... everything works fine if i'm not using setTimeout
IE...
manipulateMap(lat,lng,zoom);
that works... so i know that my failure is definitely in the way i'm
trying to call setTimeout
the whole reason for doing this is because i'm calling things so fast,
that google maps isn't responding, so this is a workaround
i've trying to do it with javascript, but the concatenation gets too
crazy, and it takes 45 minutes to add arguments because of the
troubleshooting with javascript, so i'm trying to use the setTimeout
in flex rather that the javascript one

it into a data structure on the client side for easier
manipulation. If I do something liek
class Foo {
var prop1:String;
...
}
then I could use code completion to refer to properties
of an instance of Foo. (I am lazy, and sometimes it's hard
to remember what properties are called). But on the downside,
in order to marshal/unmarshal this object into the raw
object, I need to know these properties. On the other hand
if I make Foo dynamic, and make the property names into constants,
I could use code completion in a bit more unwieldy way:
foo[Foo.prop1] = 'xxx'
and can also iterate through all these properties which is very
convenient for this marshaling/unmarshaling business.
Is there something that would let me combine the best of both
worlds?

RE: [flexcoders] setTimeout in flex 2.0
The docs advise using Timer instead.
If you are trying to use this to wait for the result of an external data
call, you are making a mistake.

Subject: [flexcoders] setTimeout in flex 2.0
I'm confused on how to use setTimeout
i have a function that i need to wait 500 milliseconds to call...
var aVars:Array = [lat, lng, zoom];
trace(aVars); //39,-105,6
var my_timedFunction:uint = setTimeout(manipulateMap,500,aVars);
public function manipulateMap(lat:Number,lng:Number,zoom:Number):void{
u = new URLRequest(javascript:map.setCenter(new GLatLng( + lat + ','
+ lng + '),' + zoom +));
navigateToURL(u,_self);
}
this makes everything come to a screeching hault, and it tells me i
have an invalid number of arguments, it wants 3 arguments but says
only one is passed
anyone have an example of passing arguments with setTimeout?
ps... everything works fine if i'm not using setTimeout
IE...
manipulateMap(lat,lng,zoom);
that works... so i know that my failure is definitely in the way i'm
trying to call setTimeout
the whole reason for doing this is because i'm calling things so fast,
that google maps isn't responding, so this is a workaround
i've trying to do it with javascript, but the concatenation gets too
crazy, and it takes 45 minutes to add arguments because of the
troubleshooting with javascript, so i'm trying to use the setTimeout
in flex rather that the javascript one
Any help would be great

[flexcoders] Re: Problems with dynamic column series showDataEffect
The reason you don't see the effects trigger is because you're adding elements to the chart, you're not changing the underlying data for the chart. You might want to try going through first and setting up the columns like you have but pointing yField to a dummy column, say intervalN. This will create the columns and set the effects. Then after that, you would loop through again and change just the yField property to point to the right column. This will cause the showDataEffect to trigger and you should see your animation.

[flexcoders] Re: Problems with dynamic column series showDataEffect
I played around with this some more. The fix was pretty easy.. just
add one line resultchart.hideData(). At least this worked for me.
public function appendInterval(column:String):void
{
resultchart.hideData();
var series:ColumnSeries = new ColumnSeries() ;
series.xField = 'label' ;
series.yField = column ;
series.setStyle(showDataEffect, slideIn);
series.setStyle(hideDataEffect, slideOut);
var currentSeries:Array = resultchart.series;
currentSeries.push(series) ;
resultchart.series = currentSeries ;
}
Re: [flexcoders] Re: SEO Compatibility
What you have described is basic deep linking, but does not solve the problem I have been attempting to articulate. Regardless of what goes on on the server, if you enter some path info after the .com part of the url, the server thinks it is getting its data from that location (foo.com/bar/ for example). The problem occurs after the initial page is loaded in whatever app you are running on the client. Let's say for example that you want to move the user from foo.com/bar/ to foo.com/foo - there is no way to update the browser without causing the full page to reload. This is why we rely on the hash portion of the url. That part does not cause the page to reload, since it is generally meant to refer to a named anchor with in the html. This fact makes the current method of deep linking and history manipulation a huge hack BTW - which IMO means that the browser vendors aught to figure out some kind of extension to make history management and deep linking more robust for client runtimes (a simple javascript API would work - maybe something plugins could interact with directly also). We could just move them in the app, and update the url client side, but we'd end up with foo.com/bar/#foo which is just terrible (though again, its not the end of the world - I guess). Thanks!

There is only one file. So we know it works. #1 - yes. i am thinking at its most basic level, on that single catch all index page, we have a function that gets called when the page loads. that function is passed the broken down url information, ie, a object similar to the location object (contains the pathname, protocol, etc - or we define a set of global variables). these are set when the mod rewrite or referrer. i'd have to check how they do it. back to the function - then your function can parse and use logic you set up to deliver the content that you want to make available to the search engines based on the url the user or search bot requested. in your logic you may be going to the database and pulling information based on the page they request. we store that information in a variable that will eventually get written to the page underneath the swf in xml hidden inside of a script tag. #2 - the search engine does not know it is getting redirected to the index.php, index.asp, index.jsp page. all it knows is that when it asks for animals.com/carnivors/bears http://animals.com/carnivors/bears it is getting the page on bears. #3 - yes. thats right. this is described in #1. i really think some variables would be better than an object. #4 - that is not necessary. remember, the user (and their browser) and the search bot only believe in the url. they don't care or know if its a single page or a different page that gets served up. One more thing we would have to do that I did not mention in #1 was to pass a list of links to the page to be written out. These can be in a display none tag or in the no script section. And finally that url path and variables should be passed to the flash swf in the flash vars section. Dang. I think this can be done rather quickly. This would be basic. A front end / front end manager could be created for this later on top of this.

Any url that is entered into the site gets rewritten or redirected. It is a dynamic system that allows you to dynamically redirect to the content you want without hard coding paths or directories. So you would create a dynamic page (doesn't really exist - only in the database) and then an alias to reach it. For example, www.test.com/myalias http://www.test.com/myalias http://www.test.com/myalias. Actually a lot of systems use this (wordpress, etc). All urls entered in to the site would be redirected to index.php. At this point you could with the super awesome power of server side code, deliver page links dynamically and content dynamically. I recently did a project with FXT and did exactly that. You pass the data as an xml model into a script tag under the body tag. Search engines pick this up. My Flex app pulled this xml in and then used it as a dataprovider for numerous controls.

Rich, I have been out of the loop on Laszlo. I am plenty busy with my Flex work :-) If someone can come up with a concise comparison chart on Flex 2 vs Laszlo I would be interested to see it. Last I had left off, after Macromedia announced Flex 2 pricing, Laszlo announced they were going to target the DHTML runtime in addition to Flash Player 6-8 SWF runtime. Seeing your post today I googled the following: Flex 2 laszlo Some interesting stuff comes up. First, Laszlo has a new Legals project in the works that will target additional runtimes, including FP9 and Java ME: http://www.openlaszlo.org/legals http://www.openlaszlo.org/orbit Ryan Stewart inlcudes Flex 2, Apollo and Lazslo in his 10 Predictions for Rich Internet Applications in 2007 http://blogs.zdnet.com/Stewart/?p=204 And then there were these two posts taking shots at Laszlo and then Flex: Oct 17, 2006 -- OpenLaszlo Considered Harmful http://blogs.pathf.com/agileajax/2006/10/openlaszlo_cons.html Oct 18, 2006 -- OpenLaszlo doesn't harm my long-time strategy - but Adobe and Flex do! http://www.openlaszlonaut.de/2006/10/18/openlaszlo-doesnt-harm-my-long-time-strategy-but-adobe-and-flex-do/ Again, if anyone has a comparison chart that they can post, that would be nice. hth, g On 12/27/06, Rich Tretola [EMAIL PROTECTED] wrote: Anyone have any links to share?
