Re: [flexcoders] openGL overlayed on Flash
Try calling the updateAfterEvent() method of the MouseEvent you're
using to track the mouse (probably in MOUSE_MOVE, I'm guessing).
e.g.
public function onMouseMove(ev:MouseEvent):void
{
_myCursor.x = stage.mouseX;
_myCursor.y = stage.mouseY;
ev.updateAfterEvent();
}

Re: [flexcoders] How to get X, Y position/coordinates of a specific character/letter in a text field
Oh - sorry, should have said - you'll need to get at the .textField property of (for example) your mx.controls.Text object, which will give you back the raw flash.text.TextField for you to then call getCharBoundaries() on it. Unfortunately, .textField is a protected property of mx.controls.Text, so can't be seen from outside the class. The simplest way to get at it is to extend mx.controls.Text - build your own component that inherits from Text. That will give you access to the .textField property you need; then you can call methods on it as appropriate.

Re: [flexcoders] RegExpValidator Not working with code-behind

Try:
public var validIPExpression:RegExp =
/^(([01]?[0-9]\{1,2\}|2[0-4][0-9]|25[0-5])\.)\{3\}([01]?[0-9]\{1,2\}|2[0-4][0-9]|25[0-5])$/;

Could be because by directly specifying the expression, the MXML-AS
parser correctly decides to treat it as a RegExp. But when directly
binding to the value, binding sees it just as a String.

We use the code-behind technique to attach AS to MXML. Doing this has caused

In the following example, if you type about 20 zeroes into the IP field it
goes from invalid, to valid, and back to invalid. Obviously it should be
invalid after the first zero is typed and stay that way unless a proper IP
is entered. However, if you take the same regExp string and put it in the

Re: [flexcoders] Strange type-coercion error message! Ideas?
Looks like your objects belong to different ApplicationDomains. By which I mean - object 1 is created from a class called Tools.dal.dataObjects.dataInvestmentAllocation defined by module 1, and object 2 is created from a class called Tools.dal.dataObjects.dataInvestmentAllocation defined by module 2. As far as Flex knows, they are _different classes_, because they are defined in different ApplicationDomains. To fix this, make sure your module loading code passes ApplicationDomain.currentDomain, so the modules all share the same definition space.

Re: [flexcoders] Re: AIR app, need MouseMove events NOT bounded by screen
Tracy, Can't you take a different approach? This is for panning the map, yes? How about, every frame: - if the mouseX is less than a certain amount (e.g. is in the left third of the screen), pan your map left. - if the mouseX is greater than a certain amount (e.g. the right third of the screen), pan your map right. You could add more complication than that - the further it is to the edge of the screen, the higher the move acceleration or whatever. That should get around your problem - not sure if it'll give you the user experience you desire, but it could be worth trying.

var moduleName:String = contentRowItem.Module;
var topicXML:XML = new XML(topic /);

if (topicsList.length()!=1)
throw new Error(Can't find single subsection with

My general approach to this type of stuff is: break it down. Store and
trace out each part of your e4x statement in a separate variable, bit
by bit. That'll show you where it's going wrong.

That's a perfectly reasonable error. Both things compile to a class called CustomSkin - and you can't have two classes in the same project called CustomSkin.

Re: [flexcoders] Re: Why would as keyword not work
Steve, My guess at what is going on - based on my limited understanding of what you're doing - is: - You have your class definition (DetailData) compiled in to your main application and into your module. - You load your module into your main application - Because you have not specifed that you want your module to be in the same ApplicationDomain as the main application, its class definitions remain segregated from the main application's class definition. - Your module creates the DetailData (whether on return from remoting call or not) by instantiating it's own definition of DetailData (call it class DetailDataA, if that helps). - The event fires from your module to your application. - Your event handler tries to cast the created object - which is of type DetailDataA - to its _own_ definition of DetailData (call it class DetailDataB). Hence your error. No matter that the two class definitions are actually identical - because they are not in the same ApplicationDomain, the code treats them as separate. Now, if you alter your module loading so that you pass in ApplicationDomain.currentDomain as the domain you want the module to load into, the problem should go away. (ModuleLoader.applicationDomain=ApplicationDomain.currentDomain) I hope that makes some sort of sense. Of course, I may have totally misunderstood your situation!

[flexcoders] AS3 loading AS2 getBounds() issue
Hi guys, (This is an AS3 issue rather than Flex per se, but might be of interest.) I've discovered a strange bug with the AS2 MovieClip.getBounds() and MovieClip.getRect() methods. As far as I can tell, it only happens in this situation: AppA is an _AS3_ application. AppA loads AppB. AppB is an AS2 application. AppB loads AppC. AppC is an AS2 application. If you run AppA, then any getBounds() or getRect() calls on objects in AppC fail, but they work as expected in AppB. (If you just run AppB, then everything works as expected.) I've tried various variants of this; if, instead of loading AppB, you embed it into AppA at compile-time, the problem still occurs. It appears to be something to do with loading one VM1 movie into another one within a VM2 shell. For the curious, here's a Zip containing a minimal test setup: http://www.wildwinter.net/public/getBoundsBug.zip All suggestions for workarounds welcomed, as this is a real nuisance for what we're currently working on. (For reference, this is in Flash Player 9,0,115,0, using either Flex compiler 2.01 or Flex Compiler 3.0 for the AS3 and using Flash 8.0 or MTASC for the AS2.) Cheers, Ian
Re: [flexcoders] AS3 loading AS2 getBounds() issue
Hello Alex, This is nothing to do with communication between the VMs. As it happens, for our actual production app, we are using Grant Skinner's SWFBridge to communicate via LocalConnection. But the sample Zip I've provided shows the bug, and has nothing to do with VM-VM communication - a simple Loader component shows the problem. To restate the simplest test case: AS3 app A loads AS2 app B (via a Loader component) AS2 app B loads AS2 app C (via MovieClipLoader) MovieClip.getRect() and MovieClip.getBounds() _fail_ within app C, and work within app B. No communication (other than loading) required. Thanks, Ian On Tue, Mar 11, 2008 at 5:23 PM, Alex Harui [EMAIL PROTECTED] wrote: AS3 and AS2 are different VMs and cannot access each other.

Re: [flexcoders] Take two: dynamic asset creation
Hi Alex, I've submitted this as a feature request on the Flex tracker. As an aside, the simplest solution is (I think) a very straightforward change to the Flex API. If the expected data fields were extended so that as well as 'icon' you passed in 'iconArguments' and those arguments, if present, were used as arguments to the asset constructor it would solve it all. And I don't think it would impact performance appreciably - the only difference is that internally Flex would call new SomeAssetClass(someArgs) instead of new SomeAssetClass(). The parameterisation of those constructors would open up so much more potential.

[flexcoders] Dynamic class creation?
Hi all,
Got a bit of a tricky problem here that I'm banging my head against...
If you assume I have some function that returns a Class object - for
example:
getAssetClass(id:String):Class
This returns a Class object which, at some future time, will be called
with new SomeClass() to construct an instance of an object.
Let's assume that the body of the function looks something like this:
function getAssetClass(id:String):Class
{
return GenericAssetClass;
}
However, the actual behaviour I need changes depending on the value of
'id'. Effectively what I want to happen is for the returned class to
be parameterised in some way - so that when new SomeClass() is called it
evaluates to new GenericAssetClass(id).
In AS2, this was possible because constructors were just functions. I
could happily say:
function getAssetClass(id:String):Function
{
return function():Object {return new GenericAssetClass(id);}
}
However, in AS3 this won't work, as Class is quite a different thing from
Function.
Changing GenericAssetClass.prototype.constructor doesn't help, as it's
static and applies to all instances of GenericAssetClass.
Doing something like this:
function getAssetClass(id:String):Class
{
GenericAssetClass.id=id;
return GenericAssetClass;
}
class GenericAssetClass
{
public static id:String;
public function GenericAssetClass()
{
// Do something that depends on 'id'
}
}
won't help either, because as soon as you change the static
GenericAssetClass.id, that change applies to all the constructors you've
handed out.
I could do something like this:
function getAssetClass(id:String):Class
{
if (id==id1)
return GenericAssetClass1;
else if (id==id2)
return GenericAssetClass2;
// etc. as required
}
but the trouble is that there is only one, parameterised GenericAssetClass
and I can't define all the options up front - it truly is dynamic.
*sigh*
I've a feeling this ought to be possible, I just can't for the life of me
think how. Is there any way I can hook into the new Class() call somewhere?
Or uniquely identify each reference to GenericAssetClass that I've handed
out, so that I can use a lookup table during the construction phase?
Thanks in advance,
Ian
Re: [flexcoders] Dynamic class creation?
Hi Christophe, Unfortunately not, but thanks. To explain, I'll copy a response email that I just posted to Flash_tiger: - I know of getDefinitionByName, but that won't work for me as I'm not returning back different class definitions - I'm returning the _same_ class definition each time, but want to parameterise it. As to why I'm doing this / what I'm hoping to achieve... I'm writing a framework that integrates with the Flex components but which is agnostic about where its assets come from. I have (for example) a BitmapData object - never mind how I got it - and want to be able to transform it into a BitmapAsset class to pass to (say) a TileList. To do that I need to be able to pass a Class rather than an instance - a descendant of BitmapAsset. I can't pass new BitmapAsset(bitmapData), because that's an instance, not a class. I can't pass just BitmapAsset, because it doesn't have the relevant bitmapData and has no way of getting it. I need to pass some sort of dynamic class or class function which can have new X() called on it and is parameterised with the appropriate bitmapData. Does that make any sense?

Re: [flexcoders] Take two: dynamic asset creation
Thanks Arul,
The more I delve in to this and experiment with it the more I'm beginning
to think it's not possible.
Ben Stucki has an interesting post on a similar solution:
http://blog.benstucki.net/?p=42
But it relies on you needing to know exactly which component container the
resulting object is destined for, and that won't work in TileLists (because
ItemRenderers get reused).
Josh Tynjala has a slightly different solution:
http://www.zeuslabs.us/2007/09/28/actionscript-3-bitmap-image-classes-with-functions-and-loaders
But it hits the same issue that I did, which is that in AS3 Function!=Class
any more.
It feels like it _ought_ to be easy.
If it's really true that we can't use runtime-created assets with the Flex
framework without handrolling a load of different ItemRenderers or creating
our own subclasses of the Flex components, then that's very depressing and
seems ill-thought-out. :-(
Cheers,
Ian

Here's an easier way to explain the problem I posted about earler.
If I create some BitmapAssets manually rathern than using embed:
var b1:BitmapAsset=new BitmapAsset(someBitmapData1);
var b2:BitmapAsset=new BitmapAsset(someBitmapData2);
var b3:BitmapAsset=new BitmapAsset(someBitmapData3);
How do I then pass them to something like a TileList, which expects an
icon property of type Class:
var rowData:Object={label:Some Label,icon:WhatGoesHere};
Where WhatGoesHere can't be BitmapAsset (that just produces an empty
bitmap). Nor can it be b1, because that's not of type Class.
The goal here is to achieve this without creating a new ItemRenderer.
Thanks in advance,
Ian
Re: [flexcoders] Take two: dynamic asset creation
Thank you, Alex. But as I said, that's what I'm trying to avoid doing; it means that I can't supply runtime-created asset data via any other means than rewriting/extending every single Flex component that I need to do it for. That seems completely backwards, and seems an ill-thought-out strategy in the creation of the Flex framework.

It feels like it _ought_ to be easy.

Re: [flexcoders] Take two: dynamic asset creation
Thanks Arul - I've wrestled with it for about 6 hours now and am going to take a break for the night. A bunch of different avenues seem to be closed off: - You can't subclass Class - You can't replace the constructor() function of a class - You can't set any static data on the Class instance that you return, because that static data will apply to _all_ objects calling the constructor. - You can't clone a Class (effectively creating a new Class object dynamically) - You can't call new() on a Class and as said before - You can't pass a Function as the constructor as you could in AS2, or replace the constructor as you could in AS2 Ideally what we're looking for is some sort of ClassFactory or ClassProxy that can be passed as a Class. But because you can't subclass Class, that's looking impossible. I've taken a look at the native serialisation but can't see anything obvious there. Ben Stucki actually suggested creating a .swf on-the-fly in memory (as a ByteArray) - and including a new, dynamically created class in it - then loading it as a class library using Loader. That's a possibility, but it's going to be both tricky, asynchronous (I'm guessing!), inelegant and (comparatively) slow. Hopefully some brainwave will come to me overnight. :-) Cheers, Ian On 10/22/07, Arul [EMAIL PROTECTED] wrote: Dear Ian, Thanks for the links Right now I'm stuck in the same place as Josh Tynjala . old school style Function prototypes are not treated as Class. since flex components expect a class it fails But I'm going to dig further in the morning (now its 1 am in Singapore) Regards, Arul

Dan, Thanks for that; I don't think so (I'd already looked at it). As far as I can see it's only useful for things expecting a ClassFactory, not a Class.

Re: [flexcoders] Take two: dynamic asset creation
Thanks Alex. Bitmaps are only an example, here - any kind of derived Asset class suffers from the same issues. I can understand your comments about CSS skinning etc.; and that the Flex framework is designed for embedding. The particular situation I am working in requires - specifically - that image data in data-driven elements - for example, a TileList - is not from embedded images, but is from runtime-generated images (whether they are bitmaps or not is immaterial - I was using bitmaps as an example). And we are in the process of building a framework that is completely agnostic about where resources come from - from embeds, from external libraries, from user-generated code, from cloning other resources, from ByteArrays fetched across sockets etc. As I'm sure you can see, making that resource framework play nicely with existing (or future) Flex components is very much on the agenda, and we'd prefer not to have to customize existing Flex components (even via ItemRenderers etc.) if we can just use them out of the box. (This is an API which is being handed to other coders, and should therefore be as clean as possible). At the root of it all, I do find it odd that if I have dynamically generated, say, a BitmapAsset (without embedding) that I can't just pass it into a Flex Component at the point at which it needs a BitmapAsset. The trouble is, Flex needs a Class, and all I have is a (perfectly valid) instance. That seems wrong. It seems there should be some way of me being able to go backwards from my instance and find the original class. And there is, of course, but it's useless to just pass a vanilla BitmapAsset class in to Flex because you'll end up with a blank bitmap. Hence my problem. :-) On 10/22/07, Alex Harui [EMAIL PROTECTED] wrote: Anyway, if you absolutely have to do this, and you know the total number of different assets you are going to create, you can make different Bitmap subclasses that clone their bitmap data at instantiation time and assign the dynamic assets to those Bitmap subclasses. -- I don't quite get this - could you possibly expand on it further?

Regardless of what goes on on the server, if you enter some path info after the .com part of the url, the server thinks it is getting its data from that location (foo.com/bar/ for example). Not quite true. You can use mod_rewrite (on Apache) to chop up the URL - everything after the foo.com/ can be altered internally to be a request to something else entirely, without affecting the browser. e.g. the client enters foo.com/bar/monkey internally, mod_rewrite alters it to foo.com/index.php?page=bar/monkey, but the user still sees foo.com/bar/monkey in his browser. I've done it lots, I know it works. :-) You can then enter your application at any point you like based on a complete URL - e.g. passing it through to Flash as flashvars via PHP. But as you say, unless we then update the browser's location bar when we move through the app, it doesn't help much. :-) Cheers, Ian

Re: [flexcoders] Tamarin, Adobe open source the Flash player ?
Hi Tom, Just came across the same thing myself - that's a stunning contribution, if I'm reading it right. It basically looks like Adobe are providing the source of the AVM2 bytecode interpreter/runtime engine to Mozilla so that Mozilla can use it as the execution engine for their ECMAscript/Javascript engine (SpiderMonkey).

[flexcoders] Loading AVM1 content into AVM2
Hi guys, I've hit a huge hurdle when trying to communicate between AVM1 and AVM2. I've been trying to create a component - call it AVM1Loader - which will allow simple communication between an AVM2 flex app and a contained AVM1 file. In theory, it's pretty simple: - Use Loader to load the file. - Create a LocalConnection for AVM2 to talk to AVM1 - Create a LocalConnection for AVM1 to talk to AVM2 This all works fine, and communications all work. However, the problem comes with the naming of the LocalConnections. Clearly each AVM1Loader instance wants to have a differently named pair of LocalConnections; otherwise you'll get into trouble if you're trying to have two AVM1Loaders running together at the same time - or even two instances of the same Flex app running together at the same time. Generating a unique ID is easy, but I can't for the life of me work out how to communicate it to the contained AVM1 file. The obvious way would be to pass it as a parameter: e.g. _loader.load(new URLRequest(AVM1File.swf?key=+someUniqueKey)); That works, but only (apparently) once. The next time you try to load AVM1File.swf with a _different_ key (under a whole new instance of AVM1Loader) something very odd happens. The key value does get transmitted correctly on the second run, but the _root of the contained movie gets screwed up. These simple trace statements are on the root of AVM1File.swf: trace(_root); trace(_root.clip); // (Clip is an instance defined on the stage of AVM1File) trace(_parent); On the first (successful) load (i.e. loading AVM1File.swf?key=someUniqueKey), I get: _root _root.clip undefined Which is as expected. On the second run through (i.e. loading AVM1File.swf?key=someOtherKey), I get: _root _level0.App0.Panel4.contentPane.AVM1Loader40.instance55.instance56.clip _level0.App0.Panel4.contentPane.AVM1Loader40.instance55 Which is very strange - suddenly my AVM1 code is seeing its AVM2 instance name. And from that point on, the AVM1 code stops working correctly - loading clips etc. fails. If I change the URL to just AVM1File.swf it all works fine, but obviously my unique key doesn't get transmitted. Similarly, fixing the URL - sending AVM1File.swf?key=dummy each time - works fine. Somethings up when you alter the parameter. It's a new instance of Loader() - I'm not reusing anything. So - that's clearly some sort of bug, and I seem to have hit a blank wall there. If anyone's got any ideas on that peculiarity then great. But that aside, if anyone's got any brainwaves on how to simply communicate a unique ID to an AVM1 file I'm loading, that'd be great. :-) Yours in frustration, Ian -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!

Re: [flexcoders] Loading AVM1 content into AVM2
Hi Daniel, Thanks for that. If I understand you correctly, you're suggesting creating a known LocalConnection which acts as an 'ID server' in AVM2. I had thought about something similar. The issue is that I can't see how the pairing up works between an AVM1Loader (the AS3 component) and it's contained AVM1 movie. I can understand using a known point for the AVM1 movie to talk to, but can't see how you can guarantee that the right IDs can be guaranteed to be known by both parent and child if, for example, two such pairs are being created at the same time. You can't queue it - e.g. FIFO - because you can't guarantee that the first AVM1 movie loads faster than the second. And you can't even do it by URL mangling or somesuch, because we might be dealing with loading the same movie into two different components (which is the case in my setup). Additionally, I think the known server fails if (for example) two copies of the same Flex app were running at the same time - although I guess you could get around that by querying LC_DAEMON to see if it already exists before creating it. I'll play around with the idea and see if I can make sense of it; unless you've any other light to shed. :-) Thanks for the Adobe info - I'll create a simple test case and drop a note to them.Cheers, IanOn 9/16/06, Daniel Wabyick [EMAIL PROTECTED] wrote: That most definitely sounds like a bug ... I think the following would work: - Create a class LocalConnectionDaemon in AVM2 that is connected under a hardcoded LC name. ( e.g. LC_DAEMON ); - Create a class LocalConnectionDaemon in AVM1 that does the following: - Generates a unique LocalConnection URL based on the current-time-millis ( e.g. var clientId:String = LC_CLIENT_1324343243243 ) - Send a command to LocalConnectionDaemon via - LC_SERVER .. createClient( clientId ) - Listen for a command (on that same LocalConnection, or one the server can figure out) called onClientCreated( otherClientId:String ) - LocalConnectionDaemon should have a method createClient( clientId:String ) that takes the ID, and transforms it to a guaranteed unique name (e.g. var newClientId:String = clientId + _AVM2) and sends onClientCreated( newClientId ); Definitely more painful, but doable. I should point out that one big issue with LocalConnection is that messages are limited to 40kb. You may need to chunk your requests over if they are large.
