Re: [flexcoders] Parsley MVC :: some thoughts

Re: [flexcoders] Parsley MVC :: some thoughts
Not exactly, asynchronous simply means your event handler will fire some time in the future, rather than when you call addEventListener(). Not everything is a blocking dispatch, either IIRC.

Re: [flexcoders] Parsley MVC :: some thoughts
Jules, I confess I actually misread your original post - I had anticipated that when an event is despatch it wouldn't be actioned until the current code section had been completed then the player would act upon events awaiting despatch. On the face of it, if events are despatched and all handlers invoked synchronously before the next statement runs then there's an opportunity for an unexpected race condition if handlers are updating the same data structures as the code that despatched the event. Like you I would be surprised at this behaviour and I might try and check that out for myself later today. So you are right my comments don't match your findings. I don't have a problem with the event despatcher invoking all handlers for an event in sequence - event handling has a predefined order through the display list, but there's no guarantee that multiple handlers at the same place in the hierarchy will be invoked in a set sequence. I'm somewhat surprised at your assertion that despatching an event will invoke handlers for that event synchronously - it would be interesting to get a better handle on this from someone who knows thelow-level mechanism more intimately than I do. My event handling code doesn't anticipate that despatched events are handled syncronously and as i've already said, there's always a danger of an unexpected race condition if that were true. In my previous life writing a lot of code running on multiprocessor systems we took great care to control asynchronous behaviour and to protect data structures from multiple updates using semaphores. In a faux system like the flash player, there isn't true concurrency, but if what you say is true there would be a real potential of getting an unwanted side-effect since effectively shared data structures would be open to being updated unexpectedly whenever an event is despatched. So, I'm kinda with you.

[flexcoders] huge AMF messages
Hi all,
I planning to build an AIR application. In this application the user
can create libraries that consist of multiple value Entry objects.
Each EntryVO should look like this (there will be more properties of
course) :
package vo
{
[RemoteClass(alias=vo.EntryVO)]
import flash.net.registerClassAlias;
import flash.utils.ByteArray;
public class EntryVO
{
[Bindable]
public var image_data:ByteArray;
[Bindable]
public var image_name:String;
public static function register():void
{
registerClassAlias(vo.EntryVO, EntryVO);
}
}
}
To simplify the uploading and downloading process I want to transfer
images as ByteArrays to a .NetBackend.
My question: What are my limitations here file size wise? Let's say I
have 10 EntryVO. An each of these
has an 1 MB byte array embedded.
That means that my libraryVO (10 x 1 MB EntryVO) would have a file
size of 10 MB.
Will this work at all? Is there a progress event for remote
operations? I guess it will take a while to transfer
a 10 MB AMF message.
Thanks for any input!
Cheers
Robin

[flexcoders] vertical scrollbar problems...Please help i am freaking out :-)
Hello all, I do not know how many hours i have spend playing around with scroll policies, heights, tops and bottoms...but still no solution. The application layout is the following: HBOX LEFT VBOX RIGHT VBOX --PANEL --VIEW STACK PANEL 1 (lets say 200 pixels height) PANEL 2 (lets say 500 pixels height) Initialy, The viewstack show Panel 1, and when i play with smaller screen sizes, ie make firefox smaller than my monitor's full height a vertical scroll bar appears correctly (when panel 1 bottom reaches the bottom of the browser window)... The problem appears when i switch to the second panel in the viewstack (selectedIndex==1). The scrollbar appears and disappears, but it seems that the measuredHeight is wrong! The scrollbar only appears when the screen becomes less than the height of the first panel which is 300 pixels less height than the second panel making the application not usable as 300 pixels of panel 2 are hidden... Does it pop any ideas? The viewstack's resizeToContent is true... Thanks, Fotis

RE: [flexcoders] Flex Builder caching PNGs
From what I can tell FB will not detect changes in files (images, and I believe css files) by itself, so if you change one then run/debug it will think nothings different and just show the last compiled version. When I'm doing stuff like that, I've got into the habit of just adding/deleting a space character to one of the mxml or .as files in the project, which FB will then notice and force a recompile that *does* update the resource in the build. It's at least easier than renaming a whole file. If there's a better way then I'm unaware of it I'm afraid.

Re: [flexcoders] Parsley MVC :: some thoughts
I'm confused. Let's clarify what we are talking about. The event dispatching is fully synchronous. If you call dispatchEvent, all event handlers are called, before the next statement is executed. Some processes (eg loading something from the backend or a timer) dispatch events in an asynchronous manner. So they call dispatchEvent at some unknown point in time I think, this is how it works.

I'd advise simplifying things as much as possible, like creating a simple page that accepts an HTTPService request (no parameters) and returns a hard coded value (I advise xml). Then, make that page an echo page, that takes a single querystring parameter and returns it to the Flex client. Test that from a browser before you try it from Flex (using GET). Then use an htm form to submit the parm, then POST from Flex.. When you get that, you will be pretty much in business. Ah, also try it without https.

[flexcoders] AIR Application - Positioning.
Hi, I have a requirement for an application, it provides extensions based on a name entry box.

Re: [flexcoders] Defining, but not adding to parent in MXML
That's it exactly. Basically, we have a number of situations where we need
to add pop-up details to elements in our application, so I thought I'm
trying to make reusable non-visual component that orchestrates that, like
this:
mx:Whatever id=summary/
mx:Canvas id=myPopUp
mx:Label text=All sorts of useful information/
/mx:Canvas
*my:PopUpDetail
target={summary}
popUp={myPopUp}
popUpOnRollover=true
popUpOnFocus=true /*
So I've dug around in PopUpButton to see how it manages its pop-up, and that
looks simple enough. But PopUpButton uses the existence of popUp.parent to
determine whether it is managing the pop up yet (no parent, and it assumes
that it isn't) - so it seemed that, along with my not knowing about
includeInLayout=false, creating the popup control in some sort of
parentless way was important.

That's not exactly what you're after, in this case the object will be
added to the list of children, it's just not positioned on
parent.updateDisplayList() or counted during parent.measure().
The only way I can think of off the top of my head to do what you're after
is wrap it in mx:Array. Here's a quick example:
http://pastie.textmate.org/private/hjd33kkztkuojpzltd2ylw
You can use mx:component to do thins kind of like this, but
mx:component defines classes, not interfaces, and IIRC, mxmlc is kinda
picky as to where it'll let you do it.

*Subject:* [flexcoders] Defining, but not adding to parent in MXML
Is it possible to define a component but somehow cause it to be omitted
from the enclosing component's list of children? Essentially:
mx:VBox
mx:Label text=This is added as a child of the vbox, as normal./
mx:Label visible=false text=This is invisible.. but is there some
way to not have it be a child of the vbox at all?/
/mx:VBox
An obvious question is, Why are you defining the component there if it's
not supposed to be a child?
I've got a datagrid inline item renderer that always shows a (summary)
piece of information, but I want a pop-up to appear on rollover of the
summary. The problem I'm having is that the detail is (of course) added to
the container that holds the summary, which causes the datagrid cell to blow
open too big.
mx:itemRenderer
mx:Component
mx:Box
!-- This always shows up, which is fine and dandy --
mx:MySummary data={data} popUp={detail} /
* !-- It would be nice if this was never added to the parent box,
so that it's free to be used as a popup --
mx:MyDetail id=detail data={data}/*
/mx:Box
/mx:Component
/mx:itemRenderer
Defining the detail outside the itemrenderer entirely seems one way to go,
except that this would mean there's only one pop up for all of the rows of
the data grid.
Can you do this sort of thing with a nested component?
mx:itemRenderer
mx:Component
mx:Box
!-- This always shows up, which is fine and dandy --
mx:MySummary data={data}
mx:popUp
* mx:Component
mx:MyDetail id=detail data={data}/
/mx:Component*
/mx:popUp
/mx:MySummary
/mx:Box
/mx:Component
/mx:itemRenderer
Any tips would be appreciated!

[flexcoders] Please Help: Shift data Up|Down in array/datagrid
Hi everyone, hope someone can offer a suggestion to solve this, or at least let me know if it possible within Flex/ActionScript. Here is my sample data: Date Var1 Var2 - Mon 34 45 Tues67 87 Wed 83 12 Thurs 89 23 Fri 12 98 ... ...... Lets say there is more data, but this is what is visible at the moment. Question: How could I adjust the Var2 column by essentially moving it up or down within its column? So if I moved it down (perhaps adding a null reference to the first row) 45 would appear in the Tues row, however Var1 would not be changed. If we were to move it up, the 45 would be removed and the 98 in the Fri row would move to Thurs. At best, it would be good to be able to do this with a slider control and have it return to normal without destroying the original data loaded in the array. I was thinking of a custom filter function, however could not find any references that indicated it could be used in this manner. Would IViewCursor be capable of doing this? As long as the datagrid showed the changes, I would be able to perform the necessary calculations on the adjusted data - correlation. Any thoughts whatsoever would be greatly appreciated. -- Blair

Re: [flexcoders] Parsley MVC :: some thoughts
Hi Ralf, That's my understanding now too. What I'm slowly coming to terms with are the facts you so lucidly summarise below :) I (and I think Paul too) had always assumed that control returned from the dispatchEvent function immediately. I'm still a little bit shocked about it. In this light, dispatchEvent just routes function calls through a common object. It's too early to say whether it'll make much difference to how I code in Flex. I hate stories that end with a deus ex machina :) On Wed, Dec 10, 2008 at 02:47, Ralf Bokelberg [EMAIL PROTECTED] wrote: I'm confused. Let's clarify what we are talking about. The event dispatching is fully synchronous. If you call dispatchEvent, all event handlers are called, before the next statement is executed.

On the face of it, if events are despatched and all handlers invoked synchronously before the next statement runs then there's an opportunity for an unexpected race condition if handlers are updating the same data structures as the code that despatched the event. Like you I would be surprised at this behaviour and I might try and check that out for myself later today. So you are right my comments don't match your findings. I don't have a problem with the event despatcher invoking all handlers for an event in sequence - event handling has a predefined order through the display list, but there's no guarantee that multiple handlers at the same place in the hierarchy will be invoked in a set sequence. I'm somewhat surprised at your assertion that despatching an event will invoke handlers for that event synchronously - it would be interesting to get a better handle on this from someone who knows thelow-level mechanism more intimately than I do. My event handling code doesn't anticipate that despatched events are handled syncronously and as i've already said, there's always a danger of an unexpected race condition if that were true. In my previous life writing a lot of code running on multiprocessor systems we took great care to control asynchronous behaviour and to protect data structures from multiple updates using semaphores. In a faux system like the flash player, there isn't true concurrency, but if what you say is true there would be a real potential of getting an unwanted side-effect since effectively shared data structures would be open to being updated unexpectedly whenever an event is despatched.

Asynchronous means that control returns from the function call immediately although the transaction triggered by the call may still be ongoing. To me, that absolutely *requires* concurrency, even if it's simulated through a timeslicing scheduler or some such. I'm pretty sure for something to be asynchronous there has to be some sort of interleaving. That's the whole point of what I just realised: there is no such interleaving within the Flex framework. Event dispatch in Flex/Flash is a *blocking* operation. There's no scheduler or anything within the event bus. Maybe your handlers will make calls to a truly asynchronous API like network calls or something, but until they make that call and return control to the code that dispatched the event, the next line of code in your event producer object will *not* execute. I'm just freaked out that I never realised this. How have my applications even been *usable* until now?!?!? Pure luck and good API design from Adobe/Macromedia. Cheers to the Player team!

--- In flexcoders@yahoogroups.com, Paul Andrews [EMAIL PROTECTED] wrote: Jules, I confess I actually misread your original post - I had anticipated that when an event is despatch it wouldn't be actioned until the current code section had been completed then the player would act upon events awaiting despatch. On the face of it, if events are despatched and all handlers invoked synchronously before the next statement runs then there's an opportunity for an unexpected race condition if handlers are updating the same data structures as the code that despatched the event. Like you I would be surprised at this behaviour and I might try and check that out for myself later today. So you are right my comments don't match your findings. I don't have a problem with the event despatcher invoking all handlers for an event in sequence - event handling has a predefined order through the display list, but there's no guarantee that multiple handlers at the same place in the hierarchy will be invoked in a set sequence. I'm somewhat surprised at your assertion that despatching an event will invoke handlers for that event synchronously - it would be interesting to get a better handle on this from someone who knows thelow-level mechanism more intimately than I do. My event handling code doesn't anticipate that despatched events are handled syncronously and as i've already said, there's always a danger of an unexpected race condition if that were true. In my previous life writing a lot of code running on multiprocessor systems we took great care to control asynchronous behaviour and to protect data structures from multiple updates using semaphores. In a faux system like the flash player, there isn't true concurrency, but if what you say is true there would be a real potential of getting an unwanted side-effect since effectively shared data structures would be open to being updated unexpectedly whenever an event is despatched. So, I'm kinda with you. I actually had this very thing happen in my code a couple of weeks ago. I normally expect that the code in a function will all run as a block unless, of course, I'm calling out to another function. But in one case, one of the statements I was using (addEventListener, I think), opened up enough of a timing hole in my code that some other code (not the function that was being added in the event listener, which might have been partially understandable) ran unexpectedly at that point. The only solution I found was to make sure I put all of the other code that _had_ to run in that block before anything else happened above the addEventListener code. -Amy

[flexcoders] Digest Authentification in Flex
Hello, I'm trying to wrap my head around digest authentification in Flex. The point is, using a proxy is not an option. Using the HTTPService object, Base authentification is straightforward, I just add the required headers. Now, in the case of Digest auth, the problem is that the Server first sends an 401 unauthorized message, together with some initial values (nonce, qop) that have to be used later on in negotiating. The big question: how do I access these values? There are Flash/Flex classes that support digest authentification (although via proxy), so that shouldn't be a fundamental problem. However, I don't know how, and some posts on the web seem to imply that the Flash player *can't* access HTTP headers - but I can't believe this, since digest auth (by any flash or mx class) simply requires access to the nonce and qop values in the HTTP headers. May someone please shed some light on this issue. TIA, best regards, Christoph

[flexcoders] Cannot Tab to MovieClips from Flash SWF Loaded with SWFLoader
Title pretty much says it all: I have a Flex 3 application which can basically be summed up as a SWF player which loads SWF's created in Flash CS3. When the SWF's are loaded, I can interact with them using the mouse (click/mouseover, etc). However, these items cannot be tabbed to. I've been hacking around on this all morning, without much luck. I've ensured that every item in the application either has a tabIndex and is .tabEnabled or has tabEnabled=false and tabChildren=true. I've even resorted to enumerating over the child MovieClips in the swf (using swfLoaderInstance.content.getChildAt()) and setting tabEnabled and focusRect are both true, and confirming that the tabIndex on these mc's was preserved. I'm at a serious loss as to what to do next -- I can't have controls/interactions that the user can't tab to. Am I missing something simple? A setting on the SWFLoader? The Application? Hope someone's had to deal with this before and knows a solution. Jer

So say you wanted to call the setMyText(text) method of your swf, once the swf is loaded, you can simply call MovieClip(swfLoaderInstance.content).setMyText(hello from Flex) ; Google livedocs for SWFLoader for more information.

When using the locale en_US everything works fine. If we change the
locale within the additional.compiler.arguments to de_AT no swf is
created. But there is also no error message!
We are using SDK 3.2.0. Locale de_AT has been created by calling:

Within Flex Builder the build works with the de_AT locale!

Re: [flexcoders] speed of the for each looping
If you're trying to speed up your application, you should use the
profiler. Something like the difference between a manually indexed for
loop and a for-each loop is almost certain to be trivial.
If you don't have the profiler, run an ad-hoc perf test by doing
something like
// we need to construct something to iterate over:
var iterations:int = 100;
var arr:Array = [];
for (var i:int = 0; i iterations; i++) arr.push(i);
var dummy:int = 0;
var forBeginning:Number = new Date().getTime();
for (var j:int = 0; j iterations; j++)
{
// we need to do something in the loop so the whole thing
// is not just optimized out (not sure if FP does this, but
// it can), but we don't want to use trace() since I/O is
// relatively expensive compared to the cost of the loop itself
dummy = arr[j];
}
trace(for loop took + (new Date().getTime() - forBeginning) +
milliseconds);
var forEachBeginning:Number = new Date().getTime();
for each (var k:int in arr)
{
dummy = k;
}
trace(for-each loop took + (new Date().getTime() - forEachBeginning)
+ milliseconds);
That should give you an idea of the difference (but run this many times
and average it, and vary the order of the loops). Also, keep in mind
that most of the time, you won't be iterating over a million items.
Bottlenecks can occur in surprising places (though they're often found
in common places too, like Container layout code). Don't try to optimize
things that *seem like* they would be slow without actually confirming
not only that they *are* slow, but that they are affecting the overall
speed or responsiveness of your application. It makes no sense to make a
10x performance improvement in one part of your code that accounts
for .01% of your application's CPU usage.

Sorry about that. Its not really my fault. Its the flexcoder list system.
Actually I emailed one at 5pm yesterdays, waited for it to show up but it
didnt.
So I sent another one about 8:30 pm, it didn't show up either.
Then I sent one this morning and it didn't show up for an hour (when all 3

Hi wkolcz,
try not to post the same message more than once. If people don't take
the time to answer it is because the information is easily available

[flexcoders] RE: services-config.xml: compc or just mxmlc?
Hi Maciek, I don't have any practical experience with attempting to compile service config and associated classes into modules and I don't know whether compc would support it or not, but based on some informal discussions with Alex and Jeff I wouldn't recommend it. The core issue is that AMF serialization mappings (client to server class aliases) within Flash Player aren't scoped per module or even app domain as loaded classes are - unfortunately they're scoped to a security domain (broader scope). This means that if the root swf loads two or more modules (each will be loaded in its own child ApplicationDomain by default), where these modules bake in overlapping sets of classes that use [RemoteClass] metadata things won't work. The modules will effectively trample each other's registered class aliases to point to their respective local classes. Say you have a class Foo ([RemoteClass(alias=com.Foo)]), that you've compiled into both modules. You now have two separate class defs on the client (one per module/sub app domain), but only one alias registered (scoped to the security domain both of these app domains belong to). When the loosing module receives a Foo off the network it will fail to deserialize correctly because the alias mapping points to the class def in the other module, which this module doesn't have access to. I think the best approach for now is to place your service config and all shared classes with [RemoteClass] metadata into your root swf, and then expose this to your modules through a controlled API - say a registry of network services or operations the modules can use. You may be able to get away with keeping non-shared classes with [RemoteClass] metadata in specific modules, but I haven't tried that.

If I compile a .swc component with compc with one set of services defined, but then change the services-config.xml file and build a .swf with mxmlc, are the mxmlc service definitions used for everything? Is it some weird combination? I know I can probably poke at this through experimentation, but the docs explicitly *don't* list service-config as an option that does not apply to compc, so I was curious. -Maciek

A block of code is always running through without any interuption. I think this has been part of the discussion in the thread. While it is what I would expect, if dispatching events causes all listening event handlers to be called synchronously, it means that any block of code dispatching an event is going to be interrupted and potentially unknown event listeners called during the execution of that code block. Here's an interesting scenario: If I have a block of code building a data structure and it has an object reference to some model. It could be that it encounters some situation and dispatches an event. The event handler may then interrogate the model, modify the model and control then returns to the executing block which is then unaware of the model change and still iterating through the model. My expectation would be that dispatch event would add the event to a queue of events ready to be handled, but those would not be handled until the code block had completed. In other systems/languages my code blocks would include semaphore handling to protect such data structures, but there's no option for me to do that in actionscript. You may argue that the developer should 'know' what may potentially happen when writing code and despatching events, but in practice who knows who may add a new event handler to the application in future and may introduce a problem. I don't have a problem with all event handlers being called when an event is fully despatched, but that's potentially dangerous if it's done in the middle of a code block. Anyway it's just a thing to keep in mind. I would agree that it's a marginal and unlikely scenario. Paul Colin Moock has a good chapter of how all this works in his nice AS3 book. Cheers Ralf.

[flexcoders] Automating Flex Modules
Hi everyone, We have a Flex app that generates various charts that also need to find their way into printed reports. While we offer on-line functionality to export displayed charts and convert them into bitmaps, we also need to allow users to generate the preconfigured charts without displaying the flash component that generates them in the browser. In other words, we need to be able to generate the charts on the server. Are there components that allow to open a flash file from the server and interact with it? Would AIR be helpful with this? Any kind of guidance or direction would be greatly appreciated. Regard, Denis

RE: [flexcoders] Call Flex from JavaScript
You need to pop a Javascript alert in your trackClosing() method to keep the
browser from closing until the user clicks the OK button.
This technique is a hack, but an alert generally leads to a long enough delay
in user interaction (say a second or two) to finish making your call into the
Player before the browser process exits.

RE: [flexcoders] Call Flex from JavaScript
Not that I'm aware of. Javascript alert is the only way to block a page close,
and even then only until the user clicks OK. The various close-related events
in Javascript exhibit subtle differences across browsers/versions and allowing
a script to force a page to remain open (for any length of time
programmatically including potentially indefinitely) would be a serious
security and usability issue.

I've also considered defining some interfaces and providing XML-backed implementations that would point back to the nodes in the original DOM, perhaps with binding support and caching of the typed objects.

[flexcoders] clearing out mx:DateField

RE: [flexcoders] huge AMF messages
If you sent these in a RemoteObject call, that 10MB worth of data would go to
the server in the body of a single HTTP POST. No progress events, and depending
on the receiving server it may enforce size limits on body content of HTTP
requests but they'd likely be higher than 10MB.

Subject: [flexcoders] huge AMF messages
Hi all,
I planning to build an AIR application. In this application the user can
create libraries that consist of multiple value Entry objects.
Each EntryVO should look like this (there will be more properties of course) :
package vo
{
[RemoteClass(alias=vo.EntryVO)]
import flash.net.registerClassAlias;
import flash.utils.ByteArray;
public class EntryVO
{
[Bindable]
public var image_data:ByteArray;
[Bindable]
public var image_name:String;
public static function register():void
{
registerClassAlias(vo.EntryVO, EntryVO);
}
}
}
To simplify the uploading and downloading process I want to transfer images as
ByteArrays to a .NetBackend.
My question: What are my limitations here file size wise? Let's say I have 10
EntryVO. An each of these
has an 1 MB byte array embedded.
That
means that my libraryVO (10 x 1 MB EntryVO) would have a file size of 10 MB.
Will this work at all? Is there a progress event for remote operations? I guess
it will take a while to transfer
a 10 MB AMF message.
Thanks for any input!
Cheers

[flexcoders] getBitmapData from a scaled display object
I'm trying to figure out the easiest way to get bitmapdata from a
displayobject that has had its scalex/scaley altered. In the test
example I have listed below, I have a canvas container that has 3
children (swfLoader components). I set the scalex/scaley of the canvas
container to 2 and its' children are scaled up proportionally;
however, when I try to get bitmapdata from the canvas, it does not
recognize the scaled size of the canvas container and as such when I
create a new bitmap using the data it is still at the original size.
Any ideas on how I can get bitmapdata that will match the width/height
of the scaled canvas would be greatly appreciated!

RE: [flexcoders] WebDAV and Flex - Any sample code or opensource widgets available . . ?
Agreed, but one caution: Implementing things from scratch on top of flash.net.Socket may be an option for some limited use cases, but without the direct browser integration it doesn't make for a great general solution (in the case of WebDAV, or for general HTTP) You lose integrated auth (NTLM for instance), security (SSL/certificate truststore and UI to manage it), state (cookies - whether you love them or hate them), etc. that the Player gets for free when it uses the browser's HTTP stack.

RE: [flexcoders] errorTip fontSize break the tooltip? Possible bug?
I'd say that's a bug. Tooltip doesn't re-measure correctly. Note that it
would never auto-resize once it did measure correctly since parents size their
children in Flex so you'd have to size the Tooltip later.
ToolTip basically expects its styles to be set in the errorTip style
declaration and should evaluate that properly within createToolTip. You can
provide an alternative ToolTipClass that handles your situation.

If you're trying to speed up your application, you should use the

something like

var arr:Array = [];

// we need to do something in the loop so the whole thing

var forEachBeginning:Number = new Date().getTime();
for each (var k:int in arr)

That should give you an idea of the difference (but run this many times
and average it, and vary the order of the loops). Also, keep in mind
that most of the time, you won't be iterating over a million items.
Bottlenecks can occur in surprising places (though they're often found
in common places too, like Container layout code). Don't try to optimize
things that *seem like* they would be slow without actually confirming
not only that they *are* slow, but that they are affecting the overall
speed or responsiveness of your application. It makes no sense to make a
10x performance improvement in one part of your code that accounts
for .01% of your application's CPU usage.

That's it exactly. Basically, we have a number of situations where we need to
add pop-up details to elements in our application, so I thought I'm trying to
make reusable non-visual component that orchestrates that, like this:
mx:Whatever id=summary/

mx:Label text=All sorts of useful information/
/mx:Canvas
my:PopUpDetail
target={summary}
popUp={myPopUp}
popUpOnRollover=true
popUpOnFocus=true /
So I've dug around in PopUpButton to see how it manages its pop-up, and that
looks simple enough. But PopUpButton uses the existence of popUp.parent to
determine whether it is managing the pop up yet (no parent, and it assumes that
it isn't) - so it seemed that, along with my not knowing about
includeInLayout=false, creating the popup control in some sort of parentless
way was important.

That's not exactly what you're after, in this case the object will be added to

The only way I can think of off the top of my head to do what you're after is
wrap it in mx:Array. Here's a quick example:

You can use mx:component to do thins kind of like this, but mx:component
defines classes, not interfaces, and IIRC, mxmlc is kinda picky as to where

problem I'm having is that the detail is (of course) added to the container
that holds the summary, which causes the datagrid cell to blow open too big.
mx:itemRenderer
mx:Component
mx:Box
!-- This always shows up, which is fine and dandy --
mx:MySummary data={data} popUp={detail} /
!-- It would be nice if this was never added to the parent box, so that
it's free to be used as a popup --
mx:MyDetail id=detail data={data}/
/mx:Box
/mx:Component
/mx:itemRenderer
Defining the detail outside the itemrenderer entirely seems one way to go,
except that this would mean there's only one pop up for all of the rows of the
data grid.
Can you do this sort of thing with a nested component?
mx:itemRenderer
mx:Component
mx:Box
!-- This always shows up, which is fine and dandy --
mx:MySummary data={data}
mx:popUp
mx:Component
mx:MyDetail id=detail data={data}/
/mx:Component
/mx:popUp
/mx:MySummary
/mx:Box
/mx:Component
/mx:itemRenderer
Any tips would be appreciated!
Michael

RE: [flexcoders] speed of the for each looping
For each should be much slower than a basic iterator as it has to walk the
object's properties.
For each (var p:* in someObject)
And
For (var p:String in SomeObject)
Probably run at the same rate.

Subject: [flexcoders] speed of the for each looping
Hi, all you experts :)
I'm tying to speed up my application and I use a lot of
exsample
for (var i:int = 0; i 5; i++)
{
trace(i);
}
so is the for each looping faster ?
RE: [flexcoders] Please Help: Shift data Up|Down in array/datagrid
What do your datastructures look like before and after? From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of cox.blair Sent: Tuesday, December 09, 2008 4:44 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Please Help: Shift data Up|Down in array/datagrid Hi everyone, hope someone can offer a suggestion to solve this, or at least let me know if it possible within Flex/ActionScript. Here is my sample data: Date Var1 Var2 - Mon 34 45 Tues 67 87 Wed 83 12 Thurs 89 23 Fri 12 98 ... ... ... Lets say there is more data, but this is what is visible at the moment. Question: How could I adjust the Var2 column by essentially moving it up or down within its column? So if I moved it down (perhaps adding a null reference to the first row) 45 would appear in the Tues row, however Var1 would not be changed. If we were to move it up, the 45 would be removed and the 98 in the Fri row would move to Thurs. At best, it would be good to be able to do this with a slider control and have it return to normal without destroying the original data loaded in the array. I was thinking of a custom filter function, however could not find any references that indicated it could be used in this manner. Would IViewCursor be capable of doing this? As long as the datagrid showed the changes, I would be able to perform the necessary calculations on the adjusted data - correlation. Any thoughts whatsoever would be greatly appreciated. -- Blair
RE: [flexcoders] Re: Item Renderer focus on subcomponent in List
That sounds like you're still calling preventDefault on the keyFocusChange
event.

Subject: [flexcoders] Re: Item Renderer focus on subcomponent in List
I fixed the run time error by writing a function to pass the two text
box variables back to the data provider. (ItemEditEnd=func(event);)
Fixed it. So now I can tab into the List's first component but once
focus is on the first renderer I can only tab and shift between the
two boxes in the first renderer. It's like the focus is stuck there.
Any ideas.
Here is the code I added for the ItemEditEnd function. Not sure if
that messes up tabbing and focus.
---
public function endEditRenderer(event:ListEvent):void {
event.preventDefault();
list.editedItemRenderer.data.first=
Renderer(event.currentTarget.itemEditorInstance).firstName.text);
list.editedItemRenderer.data.last=
Renderer(event.currentTarget.itemEditorInstance).lastName.text;
list.destroyItemEditor();
list.dataProvider.itemUpdated(list.editedItemRenderer);
}
RE: [flexcoders] getBitmapData from a scaled display object
You may have to play with some of the positioning, but use the second
parameter of the bitmapData.draw() function to pass in the object's
transform matrix as a start. This should get you closer...
bitmapdata.draw( displayObject2, displayObject2.transform.matrix );
HTH,

Subject: [flexcoders] getBitmapData from a scaled display object
I'm trying to figure out the easiest way to get bitmapdata from a
displayobject that has had its scalex/scaley altered. In the test
example I have listed below, I have a canvas container that has 3
children (swfLoader components). I set the scalex/scaley of the canvas
container to 2 and its' children are scaled up proportionally;
however, when I try to get bitmapdata from the canvas, it does not
recognize the scaled size of the canvas container and as such when I
create a new bitmap using the data it is still at the original size.
Any ideas on how I can get bitmapdata that will match the width/height
of the scaled canvas would be greatly appreciated!

[flexcoders] Locally generated Flex content not working with IE7
I'm having difficulty with locally generated Flex content not showing up in IE7. When attempting to view Flex-generated content from a local dev server in IE7 I get the message: Alternate HTML content should be placed here. This content requires the Adobe Flash Player. Get Flash The same content works fine in FF3. I've uninstalled the Flash players using uninstall_flash_player.exe, reinstalled Flex 3.0.2, installed the included debug versions Flash players (http://www.mediacollege.com/adobe/flash/player/version/show.html shows version 9,0,124,0 installed on both IE7 and FF3). Tried also to uninstall Flash players and to install the latest version (10,0,12,36) for both browsers. The problem doesn't go away. Flex content from elsewhere (on the web) works fine in IE7 - just not locally generated content. The -use-network switch should not be applicable because the development server is separate from my workstation (but I've tried it with true/false values and it made no difference). Any thoughts as to what could be causing the problem, and how I might be able to resolve it? Thanks! Ville
RE: [flexcoders] Locally generated Flex content not working with IE7
Sounds like an issue with the javascript in the html template you are using rather than an issue with the generated flex swf file. Check your ie browser javascript settings...
