[flexcoders] How To Disable Module Screen Updates....
We have up to 30 small modules that are getting loaded at startup and notice that the accumulative perceived loading effect is slow when creating the modules via... _module.factory.create() as IVisualElement; ... as all of the modules are competing for CPU to draw themselves. So, is there a way to disable all component rendering (i.e. screen updates) in each module until the user selects focus for each particular container/module? There's no reason to draw everything at the same time when all of them can't be seen at the same time. Imagine each module is added to a tab in tabnavigator and that only the first visible tab/module has been rendered, when any other tab is selected, the module then and only then renders itself.

[flexcoders] Re: Modules, TabNavigator, Force Render...
Follow-up #1... Use a simple 100ms timer so each tab is selected programmatically. Each tab is rendered normally although the tab stays visible throughout the rendering process and switches to the next tab when completed. A workaround is to hide the tabnavigator and restore visibility at the end. Because the tabnav isn't visible but still renders each tab, there must be a way to manually force each tab to render the contents. Hack or otherwise. Using a simple two tab TabNavigator, two modules are loaded via ModuleManager.load. A bitmap is being generated for each tab as a preview to what content exists on each tab. The first visible tab displays the bitmap normally. The second tab (not yet clicked on or shown) bitmap comes up empty as it would appear as if it hasn't rendered yet. The creationPolicy for all the associated containers is set to all. Clicking on the second tab instantly shows the content as expected. Is there a manual method to forcing the second tab to render itself so that the preview bitmap can be generated without having to click on the second tab? As a side-solution, if each tab (3 tabs in this scenario) are selected programmatically for one second, will that force a render to occur even though the next programmatically selected tab (tab three) has also been selected? i.e. first tab is visible second tab is programmatically selected wait 1 second third tab is programmatically selected

[flexcoders] Re: You are the product
As a devoted Flex Developer, Flex has been very, very good to me. I also know that technology advancements require change (I say additions). I can remember when programming in 8086 assembler wondering when I wouldn't need to use that silly old segment/offset hack, er, architecture. Segment/offset was finally rescued years later but after writing millions of lines of code. To adapt, I had to bite the bullet and added the newer architectures to my list of skills. Now here I am again, ahem, 30 years later doing the same thing. Almost six years invested into Flex and voila, gotta add something new to the resume to keep up. For me, it's not as much a change as valuing it as an opportunity to add even more skills to my toolbox. I've spent some time in the past month evaluating JS equivalents to Flex. Pickins' are slim but Sencha seemed to land nicely in my spacious Flex townhouse. If you are considering adding something to your toolbox, consider Sencha. It's as close to Flex as you're probably going to get with some nice MVC abilities for instance. I've written a couple of demo apps. and rarely have to deal with the DOM. Yes, that's right folks, none of that JS - DOM yakkity-yak. They even offer a Screen Designer to eliminate the screen layout guesswork. If you can't tell, I'm happy with Sencha thus far and can now say that I'm a Flex Developer AND a Sencha Developer. Give it a whirl or any try any other JS solution. Your resume will only grow. ;)
[flexcoders] Flex, HTML5, Javascript...oh my!
As a devoted flex developer of over five years now, I'm getting the nudge by management to get as comfortable with HTML5/Javascript as I currently am with MXML/Actionscript. Not my decision. That said, I figured this forum would be better suited to answer a few questions about html5/javascript rather than a endure throught a few flash-hater filled javascript forums. ;) Knowing the following about common flex development practices, what are the analogs with flex when using javascript, if any at all? FlashBuilder = ? (i.e. dreamweaver?) MXML = HTML Actionscript = Javascript RobotLegs = ? AS3Signals = ? Others, feel free to contribute... Also, Using Robotlegs affords many comforts towards MVC development practices. In that context, can other analogs be made in HTML5/Javascript where separate files are used for each of these areas? Links and/or examples would be great. View = ? Mediator = ? Service = ? Model = ? Controller = ? Dependency Injection = ? Signals = ? It would appear as if SproutCore shares some of the attributes we enjoy in Flex but would like to hear what Javascripts frameworks are most friendly to Flex Developers. Thanks in advance!
[flexcoders] IE8/ActiveX FlashPlayer Bug?
I believe there is an anomaly within the ActiveX Flash Player that is causing a 1009 error when trying to center a simple popup. This logic runs fine on all non-IE OSX and Windows browsers thus causing me to think it's specific to ActiveX Flash. One thing that may be unique here is that we are using loadForCompatibility=true.

[flexcoders] Flash Player Detection / ServerSide
Does anyone have any knowledge of how to detect whether or not a simple REST
call to a server (java/php/etc.) is from the Flash Player (flex app)?
It would appear that application/x-shockwave-flash can be detected by the
server in the HTTP_ACCEPT header as long as the type is defined in the html
wrapper like this...
embed src=${swf}.swf quality=high bgcolor=${bgcolor}
width=${width} height=${height}
name=${application} align=middle
play=true
loop=false
quality=high
allowScriptAccess=sameDomain
type=application/x-shockwave-flash
pluginspage=http://www.adobe.com/go/getflashplayer;
/embed
Outside of this methodology, is there another approach or perhaps something the
flash player sends along with each request?
I saw this reference as well so any additional comments are welcome.
The HTTP_X_FLASH_VERSION HTTP field, which returns the players
FLASH version in a server side script, only appears to be available when
opening a .swf in Internet Explorer.
Nothing is returned for HTTP_X_FLASH_VERSION
when opening the same .swf in Google Chrome
or Firefox 3+.

Based upon the Steve Jobs thread, we all have an opinion on what we believe is the Holy Grail for creating/deploying cloud applications.

[flexcoders] Re: how to handle remote requests the never return or get lost?
I agree with Rick. For all net calls, I have a timer going and a simple queue that is populated when sending each request. When and if they return sometime later, they are removed from the queue. If requests aren't received by some set timeout, they are ignored. I employ the use of tokens for each request so I know if I should ignore them or not if they are expired by my timeout. You could also log the failure to the server or trace if you want to track them. james --- In flexcoders@yahoogroups.com, Rick Genter rick.gen...@... wrote: On Mon, May 3, 2010 at 1:14 PM, Baz li...@... wrote: If you send a request to a web service, and for some reason that request never returns because it got lost on the net, or some other failure.

[flexcoders] Re: XMLListCollection DataGrid Performance vs Any Other DataProvider Type
This code will convert for you...
You need to replace the xmllist.myxmldata with your own xml structure names.
private function convertXmlToArrayCollection( myxml:String
):ArrayCollection
{
var xml:XMLDocument = new XMLDocument( myxml );
var decoder:SimpleXMLDecoder = new
SimpleXMLDecoder();
var data:Object = decoder.decodeXML( xml );
var array:Array =
ArrayUtil.toArray(data.xmllist.myxmldata);
return new ArrayCollection( array );
}
A quick follow-up after I made this tweak to use objects vs xml.
In my case, performance increased by about 20% when scrolling on a 24 monitor
browser full-size by reducing the number of renderers from 10 to 3. I then
pre-translated the original xml data in the conversion so that I didn't need to
do it with a label function.
Performance is now acceptable in full-screen (24) mode.
Bottom-line, avoid renderers. Label functions are better but are still taxing
on the performance if there is a bunch of computing going on in those
functions. Pre-render data when converting from xml to objects.

[flexcoders] Re: How to identify which child of tabNavigatoris clicked?
The oldIndex is the tab that was current before you click on another tab. So
if you have two tabs (like in the demo) with the indices of 0 and 1 and you
click on the second tab, the oldIndex will be zero (0) and the new tab will be
one (1). If you then click on tab 1, oldIndex will be 1 and newIndex will be 0.
The demo app. posted outputs that information in the trace window.

[flexcoders] Re: Do you guys consider Flex3/4 be a niche(Market)?
This is an open-ended question but I'll give it a whirl... I don't see Flex per se as the linchpin in defining a niche market. I see it as a vehicle to help bring real-world software engineering practices to web-based applications. I've spent over twenty-five years in strict software engineering practices organizations primarily using C++ and Java. Both of these languages have been the foundation for large applications (standalone web-based) for many years as they are easily scalable as well as being highly maintainable and they offer/promote strong reuseability. Flex/AS3 is a nice addendum to both C++ and Java. It scales nicely and promotes / forces you into writing maintainable and reusable code using packages and true OOP classes. Depending on whether or not the so-called rich-client continues to expand, Flex/AS3 will always flourish especially when the application becomes tens of thousands of lines of code. I don't see Javascript in its' current form (Object-based vs Object-Oriented) a strong foundation in promoting the maintainability / reuseability that Flex/AS3 offers in large-scale rich-clients. I have yet to write a javascript based application that is near the size/complexity of applications I've written in Flex/AS3. It gets too unwieldy very quickly and un-manageable for large development teams. For example, I have a Flex/AS3 application that is roughly a megabyte (compiled using external RSL's) in size and the number of packages/files is enormous as is the number of lines of source. No management team would ever consider taking this on in JS. With all this said, there will always be a demand for good Flex/AS3 developers especially in companies that require strong software engineering practices. I also think the solutions that are now appearing that convert MXML/AS3 to iPhone/Android applications will also keep it alive and well. Let the bashing begin... --- In flexcoders@yahoogroups.com, fred44455 fred44...@... wrote: I wonder if you consider Flex being still a niche market or something extremely popular?

[flexcoders] Re: Vertical separator in MenuBar
Here's a starting point for you.
To get a leg up on this the next time around you need to do something special
like this, dive into the base class source code (menubar.as in this case) and
look around to get a feel for what is happening within the default component.
For this question, I dove right in and noticed that the updateDisplayList was
looping through each menu item. From there I created a new class based upon
MenuBar and over-rode the updateDisplayList method. Voila, a quick and easy
answer.
Also, it would be considerate for all who respond to these type of questions to
post working code that can be easily pasted into FB as well as describe in
detail what you did to solve it. It doesn't help too much when we push off the
answer and not explain how to solve it the next time. I spent 10 minutes to
create the sample and respond which will go a long way for all the other
developers who will google flex MenuBar vertical line.

1. You should not be setting a loaderContext. It doesn't affect this

2. I thought the original goal was to get the sub-apps popup to center

between two lines. If the goal is to center in the main app, I
adjusted the code to look like this:

The upper/left-hand corner of the dialog appears between the two

I didn't see that small note to move the loadForCompatibility before the load. Now that I have done that, I get this error when sending the test event message.

I've moved the loadForCompatibility and the resizing event is now marshalled. However, the child sub-app is 3.2sdk and the parent is 3.4sdk and nobody is complaining with/without the compatibility flag. It used to though. ;( Is there a way to show an Alert from within a SWF to show which SDK it is leveraging? I've clear the flash cache with http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html so I know it isn't locally cached. http://71.36.29.20:/SubAppTestParent.html Shows the current version with... loader.trustContent = true; loader.visible = true; loader.loadForCompatibility = true; loader.load(http://71.36.29.20:/SubAppTestChild.swf;); // this is where resize events will return... loader.loaderInfo.sharedEvents.addEventListener(ResizeEvent.RESIZE_EVENT, newText); --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: You need to set loadForCompatility=true before the load() in order to force the child into its own applicationdomain and therefore isolate it from the version of the SDK in the parent app. Doing so will then give the parent and child different versions of ResizeEvent as you would want and expect in version isolation otherwise a change to ResizeEvent could cause a failure in the child app. The correct technique is to marshal all events going between applicationdomains. If you don't set loadForCompatibility=true before the load() and the child is truly on a different version of the SDK, you should see verify errors. If both parent and child are on the same SDK, it will work, but as soon as the parent gets a newer SDK, you will start to see verify errors.

[flexcoders] SubApplications Chapter Deux...
I've been trying to center a dialog in a sub application but haven't had any
success. All SubApplication experts can pitch-in here...
Backgrounder...SubApps are cool because two SWF's can be compiled with
different SDK's and can still work together.
The upper/left-hand corner of the dialog appears between the two HRule's
because that is where the SWFLoader resides in the parent MXML. The dialog
isn't clipped in any way.
I've tried many combinations to get the dialog to center but it won't budge.

LoaderContext is available for those who really know what they are doing and
need explicit control for some configuration we don't support with the
Marshall Plan, usually for controlling the policy file parameter. The
marshall plan does not support re-using an appdom. LoadForCompatibility
refreshes the loaderContext before each load.

[flexcoders] Flex Printing...
I've spent two days researching and playing with printing in Flex 3.4. I was somewhat excited to learn this area of Flex which I had not previously explored but have only one word (for now): Disappointing. Primarily because there are many, many unresolved defects with various parts of the printing system that render it unusable. There are a couple of alternatives but they are unprofessional at best. The PrintDataGrid works awesome if you have simple no-wrap/no-renderer rows and no more than one page and forget multi-page printing, it's a mess. Dear Adobe Flex Engineer Folk, Can anybody with authority speak openly and honestly why very little effort has been devoted to delivering something that will work out of the box? I haven't run across any other portion of the Flex SDK that is as unusable and you should be commended for that effort. It might be useful to remove all printing related documentation until it is all verified and working so others don't waste time trying to get it to work. Based upon the Bug System, very little/if any has improved for the V4 release and fixing printing defects remains low on the defect review team list. Perhaps you can help us outsiders understand the overall Print Strategy for Flex? Sincerely, Flex Developers Without Printing Folk p.s. If you need help, let's assemble a Tiger Team to get it working. ;)

[flexcoders] Re: Using URLLoader with AsyncToken
This is another starting point

--- In flexcoders@yahoogroups.com, Karthik Kailash kart...@... wrote:
Hi all,
I was trying to retrieve binary data over HTTP for my Flex application, and
was running into some stumbling blocks. HTTPService did not seem to deal
with binary data well, people said to use URLLoader. But URLLoader does not
have the nice AsyncToken/IResponder interface that HTTPService provides.
So, I did some searching and could not find anyone extending URLLoader to
provide this kind of functionality. I went ahead and took a stab at it
myself: http://pastebin.com/d7369d0e0 http://pastebin.com/d7369d0e0
Basically it wraps a URLLoader and an AsyncToken, and maps the COMPLETE,
IO_ERROR, and SECURITY_ERROR events from URLLoader to results/faults that
get raised on the AsyncToken.
Basic usage:
var tidbitLoader:AsyncURLLoader = new AsyncURLLoader();
tidbitLoader.dataFormat = URLLoaderDataFormat.BINARY;
var asyncToken:AsyncToken = tidbitLoader.load(new
URLRequest(http://localhost/SampleTidbit.swf;));
asyncToken.addResponder(this);
public function result(resultEvent:Object):void
{
trace(result);
}
public function fault(faultEvent:Object):void
{
var fault:FaultEvent = faultEvent as FaultEvent;
trace(fault: + fault.toString());
}
Is this the right way to approach the problem? Are there existing solutions?
I would love to hear feedback.
Thanks,
Karthik

A reminder that pre 3.5sdk there is a bug where the responder can get called
twice.
Bug SDK-22883 Incorrectly Functioning HTTPService responders are called twice
Steps to reproduce:
1. Run HTTPServiceTest.mxml from the attached zip file. It calls one service
that should succeed and one service that should fail.
Actual Results:
The result and the fault method of the AsyncToken responder are called twice.
Expected Results:
Each method should be called only once.
Workaround (if any):
Add a result and a fault listener to the HTTPService directly. Then the result
and the fault method of the AsyncToken responder are called only once as
expected.

[flexcoders] Re: HorizontalList itemRenderer size does not resize on refresh
I had a similar predicament recently...
In my renderer code, I setup a listener to respond to external data changes.
In my case, I just needed to call invalidateDisplayList but you could reset

ReportHorizontalList(this.parent.parent).dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,

I am using a horizontallist as an answer bar in an e-learning app. The

This works fine when the dataProvider is set. BUT there is another
requirement: after a wrong answer is clicked, there is feedback and the
answers are scrambled.
protected function tryAgain(event:Event):void
{
answers=CollectionUtils.noRepeatRandomizeXMLList(answers);
answerListRef.dataProvider=answers;

After the scrambling, the text values are represented in their new places,
and the itemRenderers are resized--but all at the minimum size, so any over
the min size need scrollbars. The resize code is called it seems before the
data is set.
I should mention that I have a similar vertical list, with
variableRowHeight set to true as well, and there the same code works fine.
How do I force the HorizontalList to resize the renderers en masse after the

[flexcoders] Re: Progress for synchronous operation
It depends on what you want to display. If you put up some kind of progress or
other status UI then immediately jump into your sync. operation, it's unlikely
the status UI will have been rendered by the time you entered it. No different
than an infinite loop in the flash player.
A couple of ideas...that I've cooked up before.
1. Break up your sync. operation by using a timer or enter frame
2. Put up a Please Wait UI and when that is visible, fire off a timer to do
your sync. work.
A reminder that Flex is event driven so if you don't let events fly, nothing
will fly.
I'm sure there are other options but I run across these often.

That to me says that it can be generated asynchronously but like I said
I really dont know.
As far as showing progress during a synchronous call it is not possible.
This is because the synchronous call does not return until it is done and
thus the UI will never get a chance to update during the process.
If you want to show something before that is possible. You could use a
timer or you may want to look at the callLater method of displayObject as
this will wait one frame before calling the method you want. This would
allow you to show say a pop up or something so they user could at least
see
something.

[flexcoders] Re: how to update a progress bar when uploading an image
There isn't a way to do this. You can simulate a progress bar but for whatever
reason, this functionality doesn't exist. If you have a look at speedtest.net,
they show download progress nicely but their upload progress is simulated.
I've thought about making another (different) request to the server to get the
number of bytes transferred, but that's a nasty hack. It also depends on how
big your files that are being uploaded. If they are all fairly large then that
might work for you.
Perhaps someone can explain the limitations within the browser framework to
help us understand why we can't get upload status. Alternatively, if you are
ambitious, go get the Firefox source Firefox and figure it out for yourself.
Anyone else have a different opinion/solution?

Does anyone know, or have a link to an example, for a tutorial on how to
repeat a background for a component? I want to apply a repeating texture to
either a Canvas or VBox but cannot seem to find a good working example. Found
a ton that work for the Application. Thanks!
[flexcoders] Re: The Alert box is at the Top Left.
You can always just move the Alert yourself...
private function popUpAlert():void{
var myMenu:Menu = new Menu();
var popUpButton:PopUpButton = new PopUpButton();
addChild(popUpButton);
popUpButton.x = this.width / 2;
popUpButton.y = this.height / 2;
var dp:Object = [{label: Alpha}, {label: Beta}, {label:
Gamma}];
myMenu.dataProvider = dp;
myMenu.selectedIndex = 0;
myMenu.addEventListener(itemClick, itemClickHandler);
popUpButton.popUp = myMenu;
}
private function itemClickHandler(evt:MenuEvent):void{
var alert:Alert = Alert.show(Are you sure? \n\n There is no
Un-Do,
'Delete *All Completed* ?',
Alert.YES| Alert.NO,
null,
responseToDeleteAllCompletedHandler,
null,
Alert.NO);
alert.move (parentDocument.width / 2 - alert.width/2,
parentDocument.height /2 - alert.height / 2);
}
private function
responseToDeleteAllCompletedHandler(evt:CloseEvent):void{
if(evt.detail == Alert.YES)
trace(Yes);
else
trace(No);

Thanks TH. That's weird, there must be something else in my code, then as
I'm still not able to get it to the center.
My hierarchy in my main.mxml is
mx.Application mainPanel myPopupButton
I tried
this.parent as Sprite
and
mainPanel.parent as Sprite
And a couple of other things..
TH,
I'm not waiting on a solution from you specifically, because you were just
explaining the facts about the popup specifically, and the need to cast that
parameter.
Maybe someone else will see this who has run into this specific situation.

Hi Steve,
Popups exist outside the normal DisplayList, so you can work around it
by setting the Alert's parent like this:
Alert.show(your text, your title, 4, parentApplication as Sprite);

Seems like until now, my Alert boxes appear in the center ok.
However, now that I am using a PopUpButton, and in response to one of
the menu item clicks I am calling Alert.show(), the popup box is stuck
at the upper left.
My popupbutton handler:
private function itemClickHandler(event:MenuEvent):void {
switch (event.index) {
case 0:
...
case 1:
Alert.show( Are you sure? \n\n There is no Un-Do,
'Delete *All Completed* ?',
Alert.YES| Alert.NO,
null,
responseToDeleteAllCompletedHandler,
null,
Alert.NO);
default:
}
}
For the parent parameter - which is supposed to be a Sprite - I tried
this.parent, hoping this would fix it, but complained of type mismatch.
Weird that the Alert works fine when calling it in response to normal
buttons on my main panel, but all of a sudden the Alert is confused
about the parent when calling the Alert.show in response to a *popup*
type button.
( maybe I should download an updated Flex sdk? it's been a couple of
months)
Any advice would help
tx,
Steve
