Re: [flexcoders] Re: Styling AdvancedDataGridItemRenderer
As a very general word of warning, I'd advise you to be more careful and expect more pain when working with the following classes (and all associated base classes, etc): AdvancedDataGrid, OLAPDataGrid, GroupingCollection. I'll try to be extremely politically correct here, but I assume you'll catch my drift... These classes were written by a different part of the Flex team, in a different part of the world, and they are quite different than the standard Flex framework code base. They often don't follow the same coding standards, and in my opinion they are not up to the same quality level that I have come to expect from the Flex framework. I'll stop at that before I make too many Adobeans mad at me, but just know that I've learned to expect a whole new kind of pain when working with those classes.

I missed the requirement to preserve leaf icons and such. Is there a reason this doesn't meet your needs, because you seem to have known this already? I didn't know that I could use my patched AdvancedDataGridGroupItemRenderer as the regular itemRenderer as well and have it just work. I assumed that there are two distinctly and yes irritatingly different classes for a reason. It turns out I am having a problem dynamically setting the icon on leaf nodes... when I use an iconFunction, the function returns the right thing but it is never drawn (even with changing out the itemRenderer). When I use a groupIconFunction, it only runs for the items that are parents. That, at least, was solved relatively painlessly. Before I realized there were two different classes handling the rendering, I forced the first column to my patched regular ADGItemRenderer (because that put the color in more rows in that column). So the only time it used my GroupItemRenderer was when it actually was displaying a group, which seems to override the hardcoded itemRenderer.
Re: [flexcoders] Re: itemRender Debug Warnings
The issue is that you are creating Objects and adding these Objects to your
dataprovider. Objects are not bindable. For a quick fix just do this:
var objDG:Object = {itemID: myID, index: myAC[myID].id, display:
gridDisplay, toolTip: tipText};
myList.dataProvider.addItem( new ObjectProxy(objDG) );
But it would be much better to get strongly-typed objects back gfrom the
server, or convert the items to strongly-typed objects instead of generic
Objects. So define a class called MyItem (or whatever) and make it a simple
class with bindable properties for itemID, index, display, and toolTip. THen
when you get your objects back from the server do this instead:
var objDG:MyItem = new MyItem();
obj.itemID = myID;
obj.index = myAC[myID].id
obj.display = gridDisplay;
obj.toolTip = tipText;
BTW, I'd argue that storing the index of the item in the collection doesn't
belong in the item itself..
Doug
myList.dataProvider.addItem( new ObjectProxy(objDG) );

I totally missed the last post or two on this topic, but I still need
to resolve this.
The full warning message looks like this, each time the itemRenderer
is used:
warning: unable to bind to property 'display' on class 'Object'
(class is not an IEventDispatcher)
warning: unable to bind to property 'toolTip' on class 'Object'
(class is not an IEventDispatcher)
The itemRenderer looks like this:
mx:Canvas xmlns:mx=http://www.adobe. com/2006/
mxmlhttp://www.adobe.com/2006/mxml
width=80
height=18 verticalScrollPolic y=off horizontalScrollPol icy=off
mx:Label text={data. display} height=100% width=100%
buttonMode= true fontSize=9 color=#535353
toolTip={data. toolTip} textAlign=center /
/mx:Canvas
My list is defined like this:
mx:List id=lstD0 left=0 top=15 right=0 bottom=0
editable=false horizontalScrollPol icy=off
itemRenderer= myComponents. myItemRenderer dataProvider= []/
The data coming back from the RO call is assiged to the
ArrayCollection like this:
private function onResult(event: ResultEvent) :void {
myArrayColl. source = event.result as Array;
}
I loop through myArrayColl and addItems to the list dataProvider
based on certain criteria.
Re: [flexcoders] Looking for the right loop
There's nothing wrong with your code. You can also use a for each loop
instead, which might be a bit faster, but doesn't give you elements in any
kind of order.
But you could try this for each loop:
for each(var thing:Object in things) {
if(thing.selected == false) {
//whatever
}
}
Just note that using a for loop from 0 to the number of items will give you
those items in order, but a for each loop will give you them in
non-sequential order.

Re: [flexcoders] Flex Efficiency
The first step here is to verify that it's really the SWFs that are causing the problem. Can you replace the animated SWFS with static assets (like very simple non-animated SWFs, or even just blank Sprite objects)? Then test and see if the performance is better. If not then it's a Flex problem. If it turns out to really be your SWFs then you're more or less stuck trying to go back and make those SWFS not take up so much CPU. I second Josh's suggestion of checking any filters on your SWFs. Try to make them as simple as possible to test. Second, what is holding the 25 SWFs that you are moving around? The biggest issue I can see if that if you're using a typical container, then moving one of the SWfs or changing it's size might be triggering an invalidation, which means that for every frame rendered there's a full loop over every item in the display list. Might be worth using a custom component to hold these 25 swfs instead of one of the Flex containers. Also, nobody has addressed the issue of why the CPU would spike after adding a popup with the PopUpManager. I was originally going to say that I thought this was probably due to the PopUpManager adding the blur effect, but if the popup is non-modal then the PopUpManager shouldn't add any blur effect to the app, so it doesn't make any sense to me why that would make the CPU usage spike.

But if there are too many they'll just post to them all. There are 2 types of crossposting people - the ones who did not receive the answer in the previous forum and the ones who cross post from the get go. The first type is OK - moderator or users can point them to a different forum. There are periods in flexcomponents that every second message gets RTFM or go to flexcoders responses. The second type needs some discipline. Here is what moderators and users do - saying this is not appropriate forum, remove the message to make life easier for the rest, giving warning bans for a day - however harsh it sounds, it works. The goal is to service the community - not to do somebodies homework. If the forums are speedy and high quality the crossposting ceases. I have seen heavily moderated product forums on compuserve (yes, before Internet) 15 years ago. You had less then one hour response (datetime US) time on 90+% of the questions. The volume was about 500 messages across 20 forums. General list was getting about 100 threads, the rest were much smaller, The answers would be actually correct ones. Vendors would have team of community moderators that would answer 50%+ of the questions in their domain - with multiple moderators per topic.

To me, the volume of emails to the list was intimidating, until I decided to manage my lists a little better through Thunderbird filtering, and be disciplined about the time I take every day to review the list, so it doesn't impact my productivity, much like I do every day with the MXNA. So I'm not convinced that splitting up the list simply to make things more efficient and the volume less intimidating for some people outweighs the potential risks. I agree with Tim Hoff (16/06/2008 10:53 PM) -- my concern is less for new users and lurkers than it is for frequent posters who are the lifeblood of this community, having to divide their precious attention from one list to however-many, which would dilute the quality of all lists, and could ultimately lead to abandonment by regular users on all lists. A community such as this must be a delicate balance between questions and answers, new users and advanced users, lurkers and frequent contributors. My concern is that for many, the formula works, our numbers are steady, and there is still a huge number of A-list participation. In attempting to improve the list, we could be killing it -- so we need to be very sure of our data before proceeding IMO. A FAQ would be very welcome, as would Doug's recommendation for most commonly asked threads, as would tags, regardless of what the decision is on the split. But I would request that FAQ links and tag keywords be indicated in the signature of each email from the list, so that the many users who don't use the yahoo list's web interface can easily find the info and know what tags to use without having to switch between their mail client and a browser, otherwise having a FAQ and anything else apart from the emails is pointless. In fact, just having a FAQ and encouraging the use of tags could help many with list post management, and provide this list the boost it needs without taking drastic measures. This would be my request, and my recommendation. In addition, we could even include in the FAQ some post management strategies, such as filtering, tagging and colour-coding to help users manage the flow. And I would suggest an automated email generated by an algorithm with some text like You have not posted in ___ months... or You have now unsubscribed... followed by please help us make flexcoders a better community experience by telling us why you have _ This would be a far less intrusive and intimidating follow up and data collection method than an email personally send from a moderator, especially one from Adobe. Some people might perceive such attention as singling them out, and using an autogenerated email would eliminate the manpower necessary to collect data on infrequent/unsubscribed accounts. If we do decide to split the list at all, I would keep the number small just to make sure. My recommendation would be to split things into just three lists: flexcoders flexnewbie flexenterprise Even though the definitions are a little fuzzy, I think flexnewbie could be defined as not the difficulty of the question but the experience the user perceives themselves to be at, so there may very well be advanced and newbie questions on both lists, and that's okay. Likewise there will probably be some crossover into the flexenterprise list. I think it's fair to say that questions involving a substantial amount of Java/data services/large teams/enterprise workflows would qualify, without requiring the definition of enterprise be defined with scientific precision to participate. Too narrow a definition is a recipe for failure, any new the list needs to be defined without being too exclusive IMO.

Re: [flexcoders] Re: Splitting FlexCoders in smaller, focused groups
How about an agreed list of acronyms that we use to prepend the Subject line with: NEWB, MXML, AS3, DESIGN, HTTP, ALL, etc., and we do the sorting ourselves with the mail rules? You can't force people to add keywords to their subjects (I'd also argues that any categories you come up with are inherently flawed and topics usually apply to many categories), since people unfamiliar with the list won't do it, and the biggest problem I see has to do with people new to Flex and this list (note that I highly support new developers getting involved and asking questions, but they should do a little research first and not ask someone to do their work for them). If people start tagging their subjects it might catch on and people might be smart enough to see the traffic on the list and adhere to the standard before posting, but I give it a very small chance. And if someone replied and changed the subject line then threading gets all jacked, which is why I suggested someone replying with a certain tag in the body of the message that we can use to filter the threads (not to categorize legit threads, simply to filter out illegitimate ones).

Re: [flexcoders] Re: Splitting FlexCoders in smaller, focused groups
Actually, this is worth going back to, because your initial email said that the group was stagnant and has plateaued with the number of new users and questions. Except your reason for bringing it up is that the traffic has gotten too much for you to read every message. So clearly the level of traffic isn't stagnant. Unless what you're saying is that about 6 months ago the traffic reached a critical level where you couldn't deal with the traffic but then it stopped growing. So I guess I'm saying I question the claim that this list is stagnant. Almost 10,000 members and an average of 100 messages a day. Are you saying that these stats have been the same for the past 6 months? And even if that is true (although I'd like to see numbers before I accept that) then I don't even necessarily think that this indicates that there's a problem. There's a simple fact that a ton of questions have already been accurately answered by this list. I would hope that the archived knowledge of the list serves to answer more and more questions that newcomers have, meaning they don't need to post the questions over and over. What is the real problem? I haven't heard anyone say that the traffic on this single list has stopped them from asking any questions (although I'm open to the possibility that this is true, and just hasn't been voiced). And largely I think that the number of people answering questions has remained high and the response times are still good. I have heard that the traffic level has stopped people from reading the questions that others ask (I certainly skim and sometimes skip entire days). I'd argue that a combination of self-moderated subject tagging, as well as more aggressive pointing repeat questions to cached answered (and then tagging the entire thread as a repeat) will largely solve this problem. So do you have numbers that indicate the stagnation you are worried about?

Re: [flexcoders] Re: Splitting FlexCoders in smaller, focused groups
I plan on gathering a complete archive of the list over the next week and doing some analysis. I'll post the full dataset once I get it compiled to let others play with it too. I'm working on a variety of ways to get a compiled list of all messages, but I think between either scraping the mail archive site and scraping the yahoo group site I should have it figured out in another week. Then of course I'll build some flex apps to crunch some of the data :) Doug On Tue, Jun 17, 2008 at 6:20 PM, Matt Chotin [EMAIL PROTECTED] wrote: As far as stats, we've had about 100 people join in the last week.

Also hard to know how many of the folks who joined are spammers, but I don't think that many :-) This is a tough position for me to comment on because we want the community to thrive and have a life of its own that isn't controlled by Adobe. That said, we clearly want to see it succeed and will involve ourselves as necessary to try to make that happen. Based on the comments I'm seeing in this thread I don't see the big clamor to divide the list. I see folks who have figured out workflows that work for them, and suggestions for how to make things more manageable. That said, the issue that Anatole raises is whether we are preventing new users from getting help, or preventing advanced users from participating. Most of those folks who have been hurt we can assume are folks who are not on the list anymore, so it's difficult to really know without some sort of data as to why they left the list. If people are willing to wait a few weeks, maybe we could work on trying to gather that data and make a decision after. Another piece of data we could use is an analysis of the kinds of posts that have happened recently, perhaps compared to posts from a year ago, and see if the skill level of posters is increasing, how many threads are going un answered, semi-subjective view of signal vs. noise. This would help us understand if there is meaning behind the low rate of increase in total number of members, as well as the generally flat nature of posts per month. Does doing this kind of analysis interest anyone? Are the folks who advocate separating the list interested in waiting for this kind of analysis? For me, it seems kind of critical to have real data before making this kind of decision, as we're going with hunches as to what's really happening here. I'd have a hard time getting behind a real split when we don't know if doing so would actually improve things.

As far as splitting lists, I still think if people want to propose potential new lists, they need to be much more explicit about what the list will be for. I'll take the enterprise example. Let's assume for a second it has only one correct meaning (which is an assumption I agree with, but many people disagree with me on that). Enterprise has become a buzzword with many different commonly understood meanings, and most of those meanings are vague. There's no way for everyone on the list to be sure that we're talking about the same thing unless someone explicitly spells out what we are talking about (I'm not going to because I'm against having a enterprise list given every way I know to interpret the word).

Lastly, I'm going to reiterate my opinion that we shouldn't separate the lists based on skill/level difficulty. The distinction is too fuzzy (Too much cross-posting and too much posting to the wrong list). Sometimes you don't know if you're question is advanced or not until you get the answer.

I'm bowing out of this discussion. Things have gotten far too polarized and nit-picky. However, I still feel it is worthwhile to at least chime in one more time because I think some of the points raised here leave developers with wrong and dangerous information. The overall opinion that you don't need to worry about re-using your source code from other clients' projects is simply false, and has the potential to get you into a lot of legal trouble. If you find yourself copying code from work you did for a previous client, please please go back and re-read the contract you signed, and be sure that you properly understand what you're doing and the legal implications. When it comes to these issues it is always better to err on the side of caution. I'll stop giving my opinion on what's right or wrong, and just say that as a developer, you need to have a thorough understanding of IP law before you go down that road, so read up and please don't rely on mailing lists for legal advice :) Doug On Thu, Jun 12, 2008 at 5:44 AM, b_alen [EMAIL PROTECTED] wrote: You can use it again definitely otherwise no one here would be allowed to do even a sorting algorithm ever again.

In reality such algorithms may be patentable or considered trade secrets. Depends, but usually there are changes for the better in each iteration.

I don't think you can do field.subField but you could use
labelFunctions to accomplish essentially the same thing. Heck, you
might even be able to set dataField = field.subField and then use a
generic labelFunction that does something like return
data[column.dataField]. Just a guess on that part but labelFunction is
definitely the core of what you'll need.

Re: [flexcoders] Re: OOP and Work for Hire
What if you spin it as a PR opportunity for the company, and ask to be able to use the code you write as the basis for explanatory tutorials, without giving away any company-specific trade secrets, and give credit to the company for contributing the code? Could be a win-win for everyone involved. You get to blaze the path for other eLearning developers, the client company gets to be seen as open and contributing back to the community, they get their name out in the blogopshere a bit with a positive spin. But get that in writing, otherwise I'd say you'll have to do the project, then write whatever tutorials you want to do from scratch. Depends on the company of course and how willing they'd be to do something like that, most large companies I've dealt with are simply too beuracratic to ever deviate from the standard agreements the lawyers drafted up. It often doesn't matter what your argument is, the lawyers wrote an agreement and that's the only one they'll ever get you to sign.

It's been almost a year since Authorware's EOD was announced, and people need something else they can do to with this type of content.

Re: [flexcoders] Re: OOP and Work for Hire
The company is buying the code that you write. They are not buying your time. They might pay you based on how long it takes you to write the code, but in the end all they care about is owning that code. If they pay you $10,000 to write code, and then you turn around to another company and bid on a similar project for $500 because you already wrote the code and you just use the same codebase, they're going to be rightly upset. Anything you store in your head is yours (lessons learned, techniques used, etc). But anything you write is theirs. That's just the way this world works. I'm surprised at the previous response about not giving ownership of the code but instead only signing a non-compete. That's a pretty sweet deal if you can swing it, but I'd be really surprised if you found a large company that would go for that. For consulting projects I know that we sometimes ask for the IP of certain portions of code (ie things not specific to the project or general utility classes), but every time we do, we explicitly ask for exactly what IP we want to hold onto (and every time it is a huge legal hurdle). Whatever you do, be completely up-front from the beginning about what, if any, pieces of what you're writing is not the client's exclusive IP. Also be sure that you have an understanding about any open source code that you are using in a client's project. Sometimes clients can be very adamant about not allowing open source code of any kind, since they don't own the exclusive rights to that. But they often change their mind after you tell them how much money they will save if you don't have to reinvent what the open source community has already done. But it's important that you and the client have the same clear understanding about all this stuff.

Re: [flexcoders] Re: SWC Encrypt 2.0 - Does it work?
Just to clarify, Andrew is in fact talking about encryption, not obfuscation. The NitroLM product (which I have not used) actually does raw byte encryption on your swf, which then gets loaded by a wrapper swf and decrypted at runtime based on a secret key that gets sent over a secure connection after valid credentials are passed to the server. You would have to be able to crack the swf encryption before a decompiler would even be able to give you any decompiled code.

Re: [flexcoders] Re: SWC Encrypt 2.0 - Does it work?
That last comment isn't true. The Sothink decompiler works just fine on Flex swfs. Here's my experience with SWF Encrypt and SWC Encrypt: - We ran SWCEncrypt on a Flex SWC and then tried decompiling a Flex app created with the encrypted SWC versus the unencrypted SWC. I could not tell any difference whatsoever. Both decompiled just fine, it appeared as if SWCEncrypt did absolutely nothing to the SWC file. I don't know if we were doing soemthing wrong (although really how can you? you just run it on a SWC), or if the encryptor doesn't support Flex SWCs specifically. - SWFEncrypt, on the other hand, works. But it does not work for Flex swfs. If you try to encrypt a full Flex SWF the encryptor goes overboard and jacks up the Flex framework code and makes your SWF unrunnable. - What did seem to work was creating a SWF module that did not include the Flex framework code, encrypting that, and loading that module into a wrapper Flex app. - Neither SWCEncrypt nor SWFEncrypt seems to actually encrypt anything, All of it can still be decompiled with the Sothink decompiler (maybe the decompiler just knows how to decrypt whatever encryption is used). SWFEncrypt does seem to obfuscate the code though. A decompiled SWF that has been run through SWFEncrypt is harder to read than a non-obfuscated one.

Re: [flexcoders] Casting Problem.. Type Coercion Failed
ALL_USERS isn't a collection of UserVO objects it seems. Looks like it's a collection of generic Objects. How did you create the collection? Did you use AMF? Did you load from XML? Somehow the objects that got created did not get created as the proper UserVO objects. So check the collection when it gets set, it's not getting set right. If you're using AMF then you might need to include a reference to the UserVO class so the compiler knows to include it, otherwise it won't get deserialized right. If you're using some other method (like loading XML, etc) then make sure in the parsing of the data that you are explicitly creating UserVO objects.

Re: [flexcoders] Performance issues while creating several instances of DisplayObject at the same
A few suggestions: - don't set explicitWidth in updateDisplayList, use setActualSize() - like Alex said, Container does extra processing, so use UIComponent as the base of both ParentView and ChildView. SInce you are managing the layout of the children manually and you don't require scrolling or clipping these componentns you don't need to overhead of Canvas - take out the updateDisplayList method of ChildLayoutContainer. Instead, use the built in layout stuff in VBox by setting the percentWidth property of the chioldren when you add them. Your method adds an additional uneccessary loop over all the children. - use UITextField instead of Label if appropriate. THe UITextField class is a bit faster when it comes to measurement and layout. Label adds the ability for the text to be truncated with ..., but that's about all you get. So if either you a) don't care if the text has ... or is simply cut off or b) the text doesn't need truncation (like for your numbers) then use UITextFiled instaed of Label - No need for the call to invalidateDipslayList in addChildView method in ParentView. This probably doesn't add much to the total time, but it's an uneeded call (adding a child automatically invalidates) With some modifications I got your sample running in under 300 milliseconds. If I converted to UITextField objects that got down to under 200 milliseconds (using UITextField and the textWidth property for measurement).

Re: [flexcoders] 5,000 record dataset needs love
Figure out where the real bottleneck is. I just did a demo app that loads over 35,000 records from an uncompressed CSV file (over 2 meg). It's all doable, you just have to figure out which part is slow. You basically have these possibilities in terms of what's taking the most time: 1. Loading 2. Parsing 3. Rendering If the time is spent loading the file then simply compressing the file and sending the compressed version across the wire might help. Using a binary protocol like AMF will get you the best transfer speed though. I actually like CSV files because they're small and easy to export from Excel. If parsing the data is taking a long time then examine what you are doing as you parse the data. Moving away from JSON will likely save time, since JSON has to be decoded and processed even before your own processing happens. I'd guess that XML would be faster than JSON, although I don't know that. If you use AMF then you mostly get this step for free, since AMF decodes as native AS3 objects (although that takes time, but it's fast). Assuming you're doing the conversion to your VOs manually, a few tips: - the big thing here is make sure that your VOs do not use databinding. If your VOs are Bindable objects or have bindable properties you will want to remove those and control the binding manually. You can still have bindable properties, but you should control the bindings yourself. - Do not parse the records into an ArrayCollection. Parse them into an Array. If you use addItem() of an ArrayCollection then the collection dispatches an event every time you add an item. Instead, parse into a simple Array, and if you want to use an ArrayCollection in your app then create your AC after the parsing and set the source of the collection. - Do the parsing in batches. If you can split up the parsing then you can keep your app UI from locking up. I usually parse around 500 records at a time This won't speed up the processing (in fact, it will add to the total time a tiny bit), but this lets you show progress as your are parsing. I have my parsers dispatching progress events as they process batches and I show that progress in a progress bar. And if the most proessing time is spent after you have your data loaded and parsed then figure out what you're doing to render that data. Try to show less items, or group the items, or something. I assume you don't need to create 5,000 renderers all at once. Use the list controls to take advantage of item renderers, etc. In my example app that loads 35,000 records the loading of the 2 meg file takes about 10 seconds. Looping over all the records and turning them into AS3 value objects takes about 2-3 seconds. Then post-processing those records to group them takes about 10 seconds (this loops over the entire dataset and does some aggregation calculations). So all in all that takes almost 30 seconds, but it's 35 thousand frickin records and during the entire process the app is responsive and progress is shown for each step.

Re: [flexcoders] Re: Large application strategy - Flex or Flash?
No current requirement for Flex components That seems like a relevant factor in the decision.. I'd argue that the lack of a need for any Flex controls is an argument for not using the Flex framework, but not necessarily for not using Flex Builder as the development tool. Even if you are doing an AS3 only Flash project, it might still make sense to use Flex Builder (or Flash Develop or FDT, I don't have experience with those). The fact that Eclipse has plugins that support SVN and CVS for version control, Mylyn for trac integration, supports ant and maven, supports code hinting, etc etc are all reasons to use FB as the dev tool. So assuming you can put your timeline-needing Flash devs in a room and give them Flash authoring and your devs can just get SWFs they don't have to edit, then it sounds like Flex Builder is probably the way to go. But if you need to tweak timeline animations you'll need to crank open Flash Authoring. But crank it up, do your work, and get the hell out so you can get back to a decent dev environment with code hinting and all the good stuff. Doug

Re: [flexcoders] binding problems
You're creating a bindable Array that is full of non-bindable Objects.
Since your Array is bindable you would be able to bind to the Array itself,
and bindings would get fired when the Array changes (ir you do something
like objs = new Array()). But inside that Array are simple Objects that are
not bindable. So no bindings will ever fire when: a) objects are added and
removed from the array, if you wanted that you should use ArrayCollection
and getItemAt(), and b) no bindings fire when properties of those Objects
get updated.
So one way to change your example is to use a VO class to hold the data that
is in those objects, and make the entire class, or certain properties,
bindable. So if you had a VO class that had x, y, percent, and type
properties that were all bindable then your example would work. If you want
a quick but pretty dirty solution try just wrapping your objects in the
ObjectProxy class, so your Array creation line might look like this:
public var objs:Array = new Array(new ObjectProxy({x:30, y:22, percent:20,
type:community}) ... );
But it's worth having a proper undertanding of how binding really works, so
I'd advise against using ObjectProxy to force binding to work.

Re: [flexcoders] binding problems
yeah, you have the right idea, VO just means Value Object (sorry, too many
business apps start to make you talk funny), and I only meant create a
specific class that has the correct bindable properties. So a class called
Circle that has a bindable property for percent (and any of the others that
would need binding supported).
And yeah, if you're loading a bunch of XML to create those circles, I'd say
convert the XML into an array of real Circle objects to get binding to work.
That also makes things a lot easier to debug, since you can investigate and
not have to wade through XML to figure out what's going on. So when you load
your XML, loop over all the circle nodes, create new Circle objects (which
have bindable properties) and set those in your array.
The main issue is just that using a generic Object, or XML doesn't make the
properties bindable. So you need to use a class that explicitly makes them
bindable.

Originally I had a class called CircleData that was a singleton, and
binding to the currentData variable; of course everytime I loaded in a new
xml, everything would change properly, but the minute I'd try changing the
data of one circle's percent, nothing on stage would be updated. Same
problem as above it seems.
So you think creating a new Circle class and binding the buttons to each
circle in an array, when changing the array(circle1.percent) (yeah, fake) --
should be enough.
By the way, love the blog. 2 thumbs up.

Re: [flexcoders] Re: What do you think of UM Cairngorm Extensions,especially for Modular Apps?
BTW, the EventGenerator class in the UM extensions is specifically for sequencing events. You can wrap a bunch of events in the EventGenerator and tell the generator whether the events should run in sequence or in parallel. Then you fire off the generator and it will queue up all the events and make sure they fire in the right order (and will wait for each one to come back, etc and give you a final result event once they all finish). Maybe EventSequencer or EventManager would have been a more self-explanatory name, but I think the idea behind the name is that the EventGenerator is responsible for creating and firing (generating) events, in order, with the option of queueing them in sequence. And yeah, there aren't many public examples out there yet that use all this stuff, but it is used internally on a lot of projects. I assume we'll be pushing out more examples, especially of how to use the EventGenerator since that's something I think a lot of people have needed to do.

For the best chance of getting your question answered be sure to use a subject similar to this: Flex is broken!!! Plz fix this bug I'm thinking about making a little flexcoders leader board to see who has answered the most questions on this list. I'm curious to see who would win between Tracy and Alex Harui. Sorry for additional unimportant blabber on the list :) Just wanted to thank Tracy for his dedication to helping everyone out.
Re: [flexcoders] how do I know when a component is invisible
Ugly way #1: Try adding a listener to SystemManager for the FlexEvent.SHOW and FlexEvent.HIDE event using the capture phase. Then when that comes in loop over all the children of the component that is being shown and do whatever it is you need to do when you find a certain component is being shown or hidden Ugly way #2: monkey patch UIComponent.

If the UIComponent has normal visibility set to true, then check if it has a parent, if so return the parent's visibility (and since you're monkey patching UIComponent that would trickle all the way up the display list) What is it exactly that you need to do if somewhere up in the display list a parent has visible set to false?

Re: [flexcoders] how do I know when a component is invisible
I did say ugly :P
If you can rely on calling a method to check for visibility something
like this in your custom component should work I'd think:
public function isReallyVisible():Boolean {
var isVisible:Boolean = visible;
var parent:UIComponent = this.parent;
while(parent != null isVisible) {
isVisible = parent.visible;
parent = parent.parent;
}
return isVisible;
}
FYI I haven't run that code at all.

Re: [flexcoders] Re: Selecting item in comboBox drop down.
Just to play devil's advocate, is there any reason you're not just
using one of the auto complete components out there? There's an
auto-complete text component in Yahoo's astra flex component set.
There's also another auto-complete text box done by some adobe peeps

google).
And some of my fellow coworkers came up with what I think is the exact

Subject: [flexcoders] Selecting item in comboBox drop down.
I am creating an enhanced ComboBox component. The feature I am
currently adding is the ability to type the letters b, o, b
and
have it find bob in the dropdown. I have the code working
reasonably well, in that it finds what I am looking for, and
selects
it.
The problem I am having is that if the dropdown is visible, it
displays the correct item, but doesn't move the list to coincide
with
the item selected so I end up with;
bob - The item selected
abel
bill
bob
chuck
what I would like is;
bob - The item selected
bill
bob - highlighted
chuck
don
Does anyone know the method that will cause the dropdown to scroll
to
and highlight the selectedItem?
As a kludge, I can close and reopen the combobox, but that looks
nasty as a person is typing.
On a related note, is there a way of telling whether the comboBox
is
open or closed?

Re: [flexcoders] Writing text directly to Graphics object.
You can draw a TextField to a BitmapData object (using the draw() method) and then use graphics.beginBitmapFill and pass in that BitmapData (make sure to specify the right matrix for where to start the fill). But no, as far as I know there is not way to do it directly, I often use BitmapData as an intermediary to do stuff like that.

My application is setup pretty basic also. I have the normal C clamp design. ie: banner on top, footer on bottom, middle is two columns (left column is nav, right column is content). I also have a button at the top of the nav column which will collapse the width of the nav column as well as expand it back so that we can maximize the area of the content area. Very standard application setup. Well, here is the issue. I check a checkbox in the DataGrid and then I click the button that shrinks the width of the nav column to widen the content area. When I do this the checkbox view becomes unchecked?!?!?!?!? But wait, there's more. The checkbox is still marked as selected. I added a change event to the checkbox and it is fired when I select the checkbox, but it is not when I change the width of the nav column, even though the check mark disappears. Any ideas?

Re: [flexcoders] Pros and cons of bindable versus dispatching one's own events?
You can make read-only properties bindable. In your case your age property is a read-only property since it only has a getter. The normal bindable stuff doesn't work on that because bindable properties require both a getter and a setter to work. But if you define only a getter you can still use the [Bindable] metadata tag, but you have to dispatch a custom event that tells everything that the value has updated. Check out these links: http://www.rubenswieringa.com/blog/binding-read-only-accessors-in-flex http://dynamicflash.com/2006/12/databinding-to-read-only-properties-in-flex-2/ (I googled for 'flex binding read only') Doug On 2/29/08, JustusLogan [EMAIL PROTECTED] wrote: I'm very new to Flex, and am trying to work through some structural issues. I'm trying to plan out my model-view separation, and am exploring how the UI listens to changes in the model. For the sake of discussion, I've attached two simplistic examples. Each example has class Human (my model) with three properties: name, date of birth (dob) and age. Name and dob have instance fields, but age doesn't since it simply does some arithmetic and returns a value. There are two custom components: one that views Human properties, and one that edits them. The question sort of focuses on the age property, with some ramifications. The first versionhttp://www.rahder.com/junk/bindable/Main%20Bindable.swf has Human defined as bindable, then binds its name and dob to fields in the UI. That works since those properties are backed by variables. But there is no age variable, so it's impossible to bind on that property. (Right?) Run the first version -- the one that uses [Bindable] on the class. If you change the person's DOB or name you see the change propogate, as expected. But if you scroll way over and choose a DOB from a few years back, you'll notice that the age do not change. So what's the right way to write the view code so it updates itself as age changes? Hopefully this can be done in a way that's the same as it handles name and dob. I *could* have Human subclass EventDispatcher (or implement IEventDispatcher, or add an event dispatcher property) and have the Human age and dob setters fire a change event -- the views could add a listener in their person setter. But that seems inconsistent: it would mean the view needs to be aware that the age property isn't backed by a variable, which seems like pretty poor encapsulation. The second version http://www.rahder.com/junk/not_bindable/Main.swfdoesn't bind Human, but instead, uses an event dispatcher for all changes to Human. The UI's code is a little more complex, but at least it consistently handles changes rather than having to handle some property changes one way and other changes another way. Is this a case where people go ahead and use a bindable business class, and accept the inconsistent handling of the property that's not associated with an instance field, with a it's no biggie, that's life attitude, or is it better in the long run to forget automatic binding and do it manually through one's own event dispatcher? Thanks for your advice! :-)

Re: [flexcoders] Re: Am I the only one who wishes EventDispatcher exposed its listeners?
It's a feature of the flex compiler, which will take the newest version of any of the classes that it finds and use that version in the final app. So when you name classes exactly the same as the Flex framework classes (in this case mx.core.FlexSprite) then the compiler will use your local version instead of the version in the framework. On other languages similar functionality is called monkey patching, so that name has kind of stuck for this approach.

Re: [flexcoders] Setting custom component properties in MXML
To go back to your original example, it does seem a bit kludgy to me too. In
this case I would use databinding like so:
mx:Canvas xmlns:mx=http://www.adobe.com/2006/mxml; width=500
height=800
mx:Script
![CDATA[
[Bindable]
public var imageSource:String;
]]
/mx:Script
mx:Panel x=100 y=100
mx:Image source={imageSource} x=10 y=10/
/mx:Panel
/mx:Canvas
If I'm making MXML components I often do stuff like that and just use
bindable public properties to pass through variables, which works well for
these simple cases.

If you are defining your component in MXML, then no, id cannot be

being public. The only way to create a component with a private id
attribute is to create the component in ActionScript, extend a subclass
of UIcomponent, then override the id getter setter. And this goes for
'redefining' any built-in property of a UIComponent class.

Bonus question - is there a way to make the component ids inside of the
main component private? (i.e., in the example above, make the id for
the mx:Image component private). Because when I see code hinting, I
see both the public property imageSource, but also the Image component's
id, userPhotoImage, which I would prefer to keep private.

Re: [flexcoders] Aha... did someone say C/C++ to AS3???
Yes, the player is fantastic. But how will adobe make money out of it if... their business model ( with regards to the flash platform ) now revolves around development tools and data/media infrastructure, not the player itself which, licensed as you say it is, didn't cost me or anyone I know a single penny. They make mad money off the player in mobile devices. So they are, in a sense, putting things at risk by maximizing portability and lending their technology for others to leverage against their mainstream products. Where's the risk? Adobe doesn't make bank from Flex Builder. They make nothing form the Flex framework itself. I don't know the numbers for how much they make from Flash Authoring, but the point is that these tools are all a means to an end. That end is getting licensable versions of the player (ie mobile) onto as many handsets as possible and selling licenses of their enterprise-level LiveCycle stuff. That's where the money is. Being able to port c++ code to AS3 has no negative impact whatsoever. All it means is that more and more code will run on the Flash Player, which generates more revenue from embedded devices and likely sells more copies of LiveCycle.

Re: [flexcoders] Tween Motion along a path
For starters, the presentation you're referring from Michael Labriola to was
just posted online: http://blogs.digitalpri
mates.net/codeSlinger/index.cfm/2007/10/28/Max-Presentation
The basic idea that I think makes sense for you to approach the problem with
is that you want a function that lays out all your items for any given
rotation of the circle. This function doesn't do anything in terms of
animating. All it does is lays out your items given a particular rotation of
your circle. So if you have a method like:
function layoutItems(angle:Number):void {
//layout all your items here for the given angle passed in
}
then you just make sure to call that function whenever you change the
rotation of your circle. You can make that happen in a setter for a property
on your class, and then you can tween that property. Not sure if that's all
making sense. Take a look at the code from the MAX preso in the link above.
You'll see a setter for a property called currentPosition. That setter calls
invalidateDisplayList(), and in updateDisplayist he's got the code that
moves all the items to their proper positions given whatever currentPosition
has been set to.
Then what he does is tweens the currentPosition property. So he doesn't have
to have a bazillion tweens running for each of his items. He tweens a single
property, and then when that property gets set, he makes sure to re-layout
the items.
If you want to go completely overboard and learn how to do crazy stuff with
animating on paths (in 2D and in 3D) then you can read up on Jim Armstrong's
blog: http://algorithmist.wordpress.com He has tons of stuff about animating
along curves and gets into the crazy math you need. That's overkill for what
you're trying to do, but worth checking out.

that the math for the path was done entirely in Flex, and it was not
using a Flash CS3 generated path. The movement was nice and smooth.
I'm trying to do my own tweening along a circular path but in a flat
2d manner. I've done all the math in action script 3 to find the
circular path but I am having trouble getting objects to move smoothly
along the path. Basically I pick a number of points along the path
and use Move effects from point to point. The more points I pick the
closer it appears to be on a true circle. I've tried both manually
kicking off each individual move effect from the effect end event and
also putting the move effects in a sequence effect. Both methods
cause the motion to be either extremely slow (if I set each move
duration to be large) or pretty jerky (if I set the move duration to
be very small like 0-2). It appears that there is a pause between the
end of each move effect before the next move effect starts.
The reason I want to do it all in code is that I want to be able to
vary the radius of my circular path dynamically. Anyone have ideas on
how I can get smoother motion along my path? Thanks in advance.

Re: [flexcoders] Re: Import Statement keeps disappearing
I noticed this prior to Beta 2 as well, basically organize imports removes a
few things that you don't want removed. mx_internal is one, and getTimer is
another I know has issues. I think this has been a problem and might have
become noticeable with beta 2 because like Jeff said, organize imports is
toggled on by default now.
Another thing I noticed that really sucked is that I had a SWC with a
certain package structure, and I also had local package structure that was
the same as the SWC package structure. Organize imports removed all the
import statements that referenced my local AS classes (ie weren't in the
compiled SWC). Yeah, that was a fun one to manually fix by hand...

Actually from what you describe I can sort of understand the issue,
in this case to access a variable in a framework super class it
required mx_internal namespace to be declared but it didnt require it
to be explicitly used in a reference.
ie to access isShowingDropdown I only need to use namespace
mx_internal I dont need to do mx_internal::isShowingDropdown.
However if I dont do mx_internal::isShowingDropdown then randomly the
import statement will be removed.

Subject: [flexcoders] Import Statement keeps disappearing
FB3 Beta2.
I have a class where I need to use the mx_internal namespace.
So I import mx.core.mx_internal and declare use namespace
mx_internal.
OK fine so far and it compiles and runs..
BUT about every 4 or 5 compiles I get an error telling me the
namespace is unknown and lo and behold the import statement has
gone.
I put it back in and off I go until the next time it occurs. In
between occurences the class files have never been closed, its just
open in my editor and I am working on it and the import only
vanishes
during the compile process.
This only happens with mx_internal but it does happen with every
class that uses mx_internal.
Has anyone seen this issue and if so what is the way to stop it
happening.
Tks.

Re: [flexcoders] possible solution for RTL (right to left) text input
let me save you a bajillion hours of work: give up on this one. RTL is too hard. Wait for player 10, which will support bi-di text. I normally don't try to shoot down people's ideas, but seriously, you're not going to solve this one. It's really damn hard. That said I'll be pretty damn impressed if you actually do it.

Re: [flexcoders] JPGEncoder with progress support?
This is doable, but requires a little more work than you probably think. To
do this you would modify JPEGEncoder, if you're using Moxie take a look at
the JPEGEncoder class around line 121. You'll see this double for loop:
for (var ypos:int = 0; ypos height; ypos += 8)
{
for (var xpos:int = 0; xpos width; xpos += 8)
{
RGB2YUV(source, xpos, ypos, width, height);
DCY = processDU(YDU, fdtbl_Y, DCY, YDC_HT, YAC_HT);
DCU = processDU(UDU, fdtbl_UV, DCU, UVDC_HT, UVAC_HT);
DCV = processDU(VDU, fdtbl_UV, DCV, UVDC_HT, UVAC_HT);
}
}
As far as I can tell that's where the bulk of the processing happens. What
you're going to want to do is add progress events dispatching in there. But
simply dispatching progress events isn't going to be enough. That would
effectively give you notifications for progress of encoding, but since flash
player is single threaded, your display won't ever have time to update while
those for loops are running.
So you'll need to split the processing up into smaller tasks and insert idle
times between them. You'll want to use the Timer class to make your code
wait for a given period (I've found that even just a few milliseconds is
enough for the display to update).
I would split up the algorithm to process one row at a time (so basically
that inner for loop gets turned into its own function). Then have the
function that processes a row start a timer once it's completed, and once
that timer completes, then run the function for the next row and so on until
you finish. That was you can dispatch a progress event for each row and the
display will have time to update.
Hope some of that makes sense.

Re: [flexcoders] Adding buttons to an Accordion header
I might try to do a full post about this soon, but you can try checking out the CanvasButton component in FlexLib. Basically this is a subclass of Button that works like Canvas, so you can easily add whatever children to it that you want. So you would use that to create your header renderer, which you can set as a header renderer because it actually subclasses Button.

Re: [flexcoders] Re: Adding buttons to an Accordion header
I'm using Flex Builder 3 and the example I posted seems to work for me. Yeah, you might not get to use Design View, but then just don't use Design View :) I didn't even realize this since I rarely ever use DV, but yeah, it won't let you drop stuff on the CanvasButton. I have no problems adding via MXML though. You're saying that if you add children in the MXML file then FB3 won't compile that? BTW, you should get the latest flexlib source code to use the CanvasButtonAccordionHeader that I just added.

Re: [flexcoders] How can I get the Accordion headerRender instances
To not answering your question and instead ask another one: Why do you need access to the header renderer? If you want to alter the label, or blank out the label, you can use a custom extension of Button and set that as your header renderer (ie if you wanted header renderers that always converted the labels to uppercase or something). Or if you just want to get access to the labels, that's simply the label property of each child, so looping over the children will get you what you need.

Re: [flexcoders] Re: Breakpoint jumps away
I've seen this mostly when you're debugging code that was compiled, then you
altered the code and are still debugging the old one. So if you're debugging
and then you add in 2 whitespace lines to the code, the debugger gets thrown
off by two lines. I've also seen this when I try to debug a module and the
app has a compiler error but the IDE didn't catch it and pretended like it
compiled anyway. The basic idea is your code doesn't match the code that was
compiled.
If you're in the middle of a debug session, you add in a bunch of code, then
you try to add a breakpoint to your new code it won't work until you stop
the debug session.
This might not be your issue at all, but that's the only time I've
experienced weird jumping of break points.

The problem i'm troubleshooting is related to that array -
listOfTitles. So
I figured at least I could stay inside the function if I'd put a dummy
assignment on the line below the push. The breakpoint _still drops
down to
the next function.
public function MenuItem ( value:String, ordinal:int )
{
this.value = value;
this.ordinal = ordinal;
listOfTitles.push(value);
}
public function get list():Array
{
return listOfTitles;

I've set a breakpoint at a specific line - a blue dot verifies the
accuracy of my double click...then when I click debug the dot jumps
all the way out of the function to a spot of zero interest to me.
whatzzthat?

Re: [flexcoders] Where to learn intermediate/advanced Flex?
Dive into the Framework source. IMO that's the best thing to study. Figure out how Adobe made all the components in the Framework. Pick something that you don't like about one of the framework components and try to change it. Subclass the framework class you want to alter and hack away. If you want some fun things to figure out try understanding how the scrolling classes work (ListBase, DataGrid, etc), that should occupy you for a while :) An approach I took was listen for what kinds of components people are asking for on flexcoders or on their blogs and try to make them. That's how nearly all my components in flexlib started.

Re: [flexcoders] Re: Using [Event...] in Custom Classes
Yeah, here's the way I think it works in the current FB 3 release anyway
(which is the way ben described too):
You put metadata in your class, something like:
[Event(name=myEvent, type=com.me.MyEvent)]
So then you type: myClass.addEventListener( and then the auto events come up
in the list that allows you to select one of the possible events. The IDE
knows that there is an event named myEvent, which is defined by the
metadata. The IDE does not know what static constant myEvent is actually
defined by, but the IDE does try to substitute in a static constant from the
MyEvent class. It just converts the string that is in the metadata tag into
a format like MY_EVENT. It converts all characters to uppercase, and then
anywhere that there is a change in case in your event it adds in an
underscore. So if you had metadata that defined an event called
myReallyCoolEvent, then the IDE would bring up code hinting that read like
this: MyEvent.MY_REALLY_COOL_EVENT.
So in you MyEvent class, if you don't have the event defined with that
naming convention, then the code autocomplete isn't going to work for you.
You'll type .addEventListener(, get the list of events that the IDE thinks
should be defined in certain constants, and then you'll have to change it
after the fact to redefine the proper const names.
I've taken to just naming my stuff based on what the IDE assumes. So if I
define an event of type myEvent, I know that I need to have MY_EVENT
constant in the event class.
There are actually a few cases of this not working with the framework
classes. I don't remember where I've seen it, but some of the internal
framework source defines events that don't conform to the proper naming
convention, so when you get the autocomplete for the addEventListener call
it actually fills in with undefined constants that won't compile.

Event metadata is definitely not ignored in AS. Take a look at just
about any class in the framework and you'll see plenty [Event] tags.
It is there specifically to provide code hinting and support for
binding in MXML.
The problem here is that the code completion engine is offering class
constants that don't exist. They seem to be based on the constant
value, with some reformatting applied to convert to all uppercase and
inserting underscores anywhere there is a lowercase next to uppercase.
So MyEvtClass.FLY = flyAway appears in the completion list as
MyEvtClass.FLY_AWAY

Jurgen,
I believe the problem here is that you are setting up a metadata tag
on
your class in actionscript which is not needed and I think it was said
that Event meta tags are ignored by the compiler in ActionScript
classes. Someone here can clear that up for us. I am not sure why,
but
it is only needed on MXML when setting up an event. Because you are
extending your class as an EventDispatcher, you only just need to
dispatch the event you are setting up.
package components
{
import flash.events.Event;
public class MyClass extends EventDispatcher
{
public static const MY_EVENT:String = myEvent;
private function myFunction():void
{
dispatchEvent(new Event(MyClass.MY_EVENT));
}
}
}
THEN you can instantiate a MyClass variable and add an event listener:
var mine:MyClass = new MyClass();
mine.addEventListener(MyClass.MY_EVENT,someHandlerFunction);
The code assist is trying to show you the events on the event
dispatcher
and there really is just the two by default (activate and deactivate).
Don't ask me why though. I always set up my Event types as constant
vars on my class, so I know I need to access them off my class name.
This should work the same way for custom Events also.
Maybe an adobe flex expert can explain this better than I, but that is
my understanding.

Tony
P.S. ( you were borrowing (some call it hijacking) another thread and
I
think it was getting missed.)

There seems to be an issue using a custom class' event metadata in an

When using an instance of that class and creating an addEventListener

Re: [flexcoders]Can't convert XML to ArrayCollection in AS3
XMLListCollection has a toArray() method.
So maybe:

it might be a bit nicer written on more than one line, but you get the idea.

Re: [flexcoders] Trouble skinning HSlider
Extend mx.controls.sliderClasses.SliderThumb
override the measure() function with something like this:
override protected function measure():void
{
super.measure();
measuredWidth = THE_WIDTH_YOU_WANT;
measuredHeight = THE_HEIGHT_YOU_WANT;
}
Then set the sliderThumbClass attribute of your Slider to the class
reference for your extended thumb class. The default SliderThumb class has a
width and height of 12 hardcoded in.

I want the slider to appear like the slider on the right. However, once it

The graphics were done in Flash CS3, and have been exported into a swf.
The CSS rule I've

Slider {

I've been searching for ways to specify the height of the thumb for a
