[flexcoders] Preserving loaded applications styles
Hi, I've built a flex 3 application, called application A, that uses compiled css, in which I set Application type selector to set all text default color to white. Now I've got application B that uses type selector styles (Application, Label, etc). Application B loads application A and I want application A to be displayed the same way it renders when running alone in the flash plyaer. As far as I know the only way to achieve that, is that app B will load application B into new partitioned ApplicationDomain. This worked just fine when testing on demo project that only uses some labels to indicate their styles. However, when I load the real application A into application B with new ApplicationDomain, I get all sort of obscure of runtime errors from the flex framework: Panel/showTitleBar() Error: Error #1023: Stack overflow occurred. at Object$/_hasOwnProperty() TypeError: Error #1009: Cannot access a property or method of a null object reference. at mx.managers::PopUpManagerImpl/findPopupInfoByOwner() Please help me with this if you've got any tips for preserving styles on loaded apps or if you've ever been into that kind of errors. Thanks in advance, Almog Kurtser.

[flexcoders] Re: Datagrid Counting row and total value
I haven't seen a really simple way and it is not natively supported by the datagrid component. You may want to check out the advanced data grid, which I haven't used and I'm sure others can comment on. I ended up writing a custom component which has two data grids, one containing the data and another which has one row which contains the totals of the selected rows. It was a reasonable amount of work to get it going, especially as this method of implementation comes with problems like the column widths having to be managed on the total grid. Other issues which I had and you may or may not want to consider are: - is your total a straightforward sum of the values? I was adding up percentages in one column, so I needed some different rules for summation, e.g. Average. - do you have ratios and therefore the post-aggregation division problem? Often the total for a ratio is sum(A)/sum(B) rather than sum(A/B). Sometimes A or B are not columns in the grid. This gives some complexity to calculating the totals. - is there any formatting involved in any of your values, e.g. currencies? - if there are multiple currencies in the table how do you sum their values? It did take me a couple of days to get the component working as I wanted, but I now use it everywhere and it is a very valuable feature. I thought about asking Adobe for help, but the reality is that there is enough which is specific to my application that I would be very surprised if a generic solution was desirable. If enough people ask I will publish my TotalGrid. Simon --- In flexcoders@yahoogroups.com, Harry Saputra [EMAIL PROTECTED] wrote: Yups, thanks, I have use arrayname.length, and its working.

[flexcoders] How to deep copy an ArrayCollection?
Hi, In my application I am using ArrayCollections to store data for series on a line chart. I need to be able to make a deep copy of these ArrayCollections so that I can make changes to the data in the copies without affecting the original data. I've searched for a while but I can't seem to find any straightforward way of doing this, all the solutions I've seen still ultimately reference the same data objects. Is there any way to do this without having to explicitly create new objects and copy values across for each item? Thanks, Iain
[flexcoders] Re: creating a new Livecycle DS project
If you are using a J2EE server like JBoss rather than ColdFusion, then you need to supply a full file path so that the compiler can upload the flex-config.xml file and build in connections to your services at compile time. I understand that you may be sharing a server for deployment, but I think I agree with Tom's comments that for your own compiling and development you should probably install JBoss locally. If you are deploying your mxml files directly to the server and compiling them there rather than producing an swf and deploying that, then you will have a slightly more complex configuration which uses a server file path for your source code folders. I have never taken this route because I consider it too risky in terms of code clashes, so I can't help. If you are in a multi-developer (multi-site) environment, then I strongly recommend that you install your own copy of JBoss and you sync locally with your source code repository and then put your code back there once you are sure it works. I don't see how deployment of swf's directly to a shared server would work in a multi-developer environment. Aren't you continually overwriting each other's last deployed swf? Test your changes locally on your own box before you submit them, demo it from there if you have to, but keep the shared server reflecting the state of the overall project, rather than the last thing someone threw up there. Isn't that total chaos? In truth I think you should have a manufacturing process which is separate to development and happens at agreed moments. That should produce your swf and jar fles and deploy it to your shared JBoss instance. If you have Java code on the back end than you can build that at the same time and pack it all up into a WAR/EAR and deploy to whatever server you use to have a common view of the current state of the code, e.g. for testing/design review. This is very clean, very reliable and very simple. You don't even need to drop your server, you can just re-deploy the WAR/EAR. This also ensures that you and your fellow developers are all using the same code base and your code will work together when the curtain goes up. If this sounds like too much process, then it needn't be, it is just a moment at which you clean a machine and build the entire project from the head of the code stream. If you have a spare box that can do the compile, then that's even better. If you aren't doing this then I wonder how you will ever know what code constitutes which released swf. If there are only two of you in development, then it is still worth it and I bet you do something not dissimilar already informally by shouting across the room. If you are deploying code directly to a production server where live users interact with your data and code, then you must be a) the perfect coder and b) have b*lls of steel - in which case I salute you.
[flexcoders] Re: How to deep copy an ArrayCollection?
In my application I am using ArrayCollections to store data for series on a line chart. I need to be able to make a deep copy of these ArrayCollections so that I can make changes to the data in the copies without affecting the original data. IIRC you can write the whole lot into a ByteArray, which serialises it as AMF in memory, and then read it back out again. Classes in your array need [RemoteClass] in order to get correctly typed objects back. ie. var ba:ByteArray = new ByteArray(); ba.writeObject(yourData); var newCopy = ba.readObject(); Stephen

Re: [flexcoders] RemoteObject call...No Result Handler: performance question
Thanks, Seth. That's kind of what I figured and was hoping to hear, but it's nice to get a qualified response instead of guessing.I was looking at recording in a little more detail that I think is justifiable, considering that it would be a significant impact on the SQL Server as well as the client. I have been looking/playing with using the CF event gateways, too, which might be an option if I decide to go forward, and bundle data to reduce requests. Thanks again! Tom Seth Hodgson wrote: When you invoke a RemoteObject, it's going to send a request via HTTP to your server which will do some processing. Regardless of whether your server returns a result or not, an HTTP response must be returned to the browser/player. That'll be parsed by the browser networking stack, passed into the player, and from there will make its way back to your RemoteObject as a ResultEvent. As far as your Flex client is concerned, you're effectively turning your invocation into a fire-and-forget operation by not registering a result handler. There's practically no overhead in the player when you don't register a result handler. All your overhead will be spent in the network roundtrip and in the TCP and HTTP stacks on the client and server. The HTTP protocol requires that a response is returned for every request, so as you're looking to tune your app just keep that in mind.

My question is this, though: If I don't define the result event, does Flex look for it anyway? That is to say, do I incur any overhead even though I don't want to do anything with a result? Using ServiceCapture, I can see that if the RO method returns data to the caller, it is passed back in the response header. But did the Flex client actually receive it? And if it did, what did it do? Did deserialization (or anything else) occur? (The minimum I can return would be a null, and I've confirmed that.) It also seems to improve overall performance if I remove the busy cursor and fault event. Basically, I just want to do something like shipping off a thread for recording actions or whatever, but not have to worry about the impact. If these RO calls were frequent enough, what kind of impact would they incur (client side)? I thought about saving a number of records/items and shipping them off in a single shot, but the idea is to collect metrics, and I don't really care for the idea of losing data just because the user left the application without logging off (ie, a bookmark or something).

I think you just need to change the to '' like so:
dataProvider={chartXML.lastResult.month.(@month_name=='01').day}
However, you might be better off doing:
dataProvider={chartXML.lastResult..month.(@month_name=='01').day}

The issue with the @attribute==blah syntax was that I have month_name
as an element instead of an attribute.
Just learned about attributes. I'm creating the xml myself in php
(which is querying oracle). So I can put the attribute in there. It
looks like it gives you much more powerful search capabilities (as well

[flexcoders] Re: How to deep copy an ArrayCollection?
this will work for just one level of depth.
i mean, if your item has a reference to another object in the model, you
will just clone the item not the object so you will have two items
referencing the same object.
Are you sure? The following works for me:
---
// set up a data structure with a few levels in it
var data = {name:'steve',
address:{city:'london', country:'uk'},
preferences:{numbers:[3,5,7,9],
drink:{name:'beer',
temperature:'warm',
brewery:{name:'fullers',
location:'chiswick'}
}
}
};
var sd:ByteArray = new ByteArray();
var dat = [data,data]; // set up an array of the objects
sd.writeObject(dat); // serialise
sd.position = 0; // need to reset the pointer before deserialising
var deser = sd.readObject(); // deserialise
---
That is the object tree 'deser' read out of the byte array is completely
distinct to the original 'data' object tree, i.e. none of the objects read
from the byte array are just references to the older objects. It's hard to
see how it could be otherwise since the original objects could easily be out
of scope by the time the deserialisation happens.

RE: [flexcoders] Re: container width parent container's width when vertical scrollbar present
Yeah, you're caught in a no-win situation. To get this right, we'd have to visit the children twice, once to figure out we need scrollbars and then again to give them final sizes. We opted to go with the current one-visit scheme for performance reasons. There's probably some way you can detect that the scrollbar is there, change the scrollpolicy and force a relayout. From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of dfalling Sent: Monday, February 04, 2008 7:33 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: container width parent container's width when vertical scrollbar present Yes, I've found that as one fix, but am not fond of it either... The application I'm working on will be run on a wide range of monitor resolutions, and it's likely that many users will not need the scrollbars in order to see the content. For them, I don't want to chop a bit of their screen real estate away in order to display an unnecessary scrollbar. At the same time, if a user doesn't have the vertical space, I'd like for flex to show the scrollbar. The hack I'm currently using is to add extra padding to the right side and disable horizontal scrolling. If the vertical bars show up, they crop that padding. This is less than ideal, as at one point (either before the bar is displayed or after) the padding will not be consistent around the content. This also steals screen space from people who don't need the bars, so it isn't ideal. I just wish there was a way to get containers to subtract the scrollbar's width from the width that they allow their children to use. They're percentage-based, so it's obvious that the intention was for them to take up as much (but no more) space available to them. --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , Alex Harui [EMAIL PROTECTED] wrote: I spend a couple of minutes on this. The rules are that, when verticalScrollPolicy=auto (default), the verticalScrollBar is not factored into the measurements and overlaps content, otherwise it would cause the scrollbar ripple. The simplest change to remove the horizontal scrollbar is to set verticalScrollPolicy=on on the outer Canvas. That way the verticalScrollBar is factored in. Because the widths are preset in this example, it is safe to do that since you know the verticalScrolLBar has to be on.

Re: [flexcoders] Loading Image Sequence into Movie Programmatically/Dynamically Generate SWF
I saw some posts on this topic and didn't see any solution to this yet. Is there a way to use Actionscript 3.0 in Flex/AIR to generate .SWF at runtime? I guess I can't call the mxml/as compiler directly. They were probably my posts on the topic... I was looking to accomplish the same thing. There's no official way to do this, i.e. you can't create MovieClip objects using any AS3 API. The only route would be to generate the SWF byte code by hand in a ByteArray then load from that (similar to what some of the mixing audio libraries do). It'd be awesome if Adobe officially provided API for this... ahem! There's also no straightforward way to do this offline, i.e. generate a SWF from a folder full of PNGs. You can do this manually in the Flash IDE; and it appears as if there is some way to do this using the MXML compiler by chaining loading frames, but I wasn't able to work out how to do it. My solution ended up being this: I created a PHP script that scanned a folder for PNGs and generated an AS class containing all of the images as embeds. The class implemented an interface that allowed the images to be queried, listed, etc. I then compiled that class to a SWF I'd load at runtime. Nothing clever, just brute force code generation. I am kind of disappointed that Adobe hasn't created any toolchain for assets to go along with Flex, everyone seems to be rolling their own. It would be dead simple for them (with their knowledge of SWF bytecode internals) to create a command-line tool that transformed a directory full of images and sounds into a SWF library. I get the vibe that compc (the component compiler, SWC's) kinda does this, but I don't quite understand if those SWC's can be used at runtime or if they're like LIB files and only usable as compilation units. I'd love to spend a few weeks building some of these tools as I don't think they'd be any kind of rocket science. I'd love to see a SWF bytecode API (in AS3) that can generate assets (code would be a bonus), and an offline toolset that can do the same. Swfmill basically did this (for offline), but it hasn't been updated to Flash9/AS2 (last I checked). Troy.

Re: [flexcoders] Re: Fail to apply UITextFormat to UITextField in custom Component
Styles can override text formating when the parent of a UITextField is
invalidated, but only having some formatting overridden is a little weird.
Functionality for setting format based on style is in the UITextField class,
I think the function is validateNow(), but I not 100% certain about that.
For future reference, I asked about font type because embeding fonts
incorrectly could account for the described behavior (as I originally
understood it), and the rendering engine for device fonts (in very few and
specific cases) also has its own quirks.

[flexcoders] Re: container width parent container's width when vertical scrollbar present
Yes, I've found that as one fix, but am not fond of it either... The application I'm working on will be run on a wide range of monitor resolutions, and it's likely that many users will not need the scrollbars in order to see the content. For them, I don't want to chop a bit of their screen real estate away in order to display an unnecessary scrollbar. At the same time, if a user doesn't have the vertical space, I'd like for flex to show the scrollbar. The hack I'm currently using is to add extra padding to the right side and disable horizontal scrolling. If the vertical bars show up, they crop that padding. This is less than ideal, as at one point (either before the bar is displayed or after) the padding will not be consistent around the content. This also steals screen space from people who don't need the bars, so it isn't ideal. I just wish there was a way to get containers to subtract the scrollbar's width from the width that they allow their children to use. They're percentage-based, so it's obvious that the intention was for them to take up as much (but no more) space available to them. --- In flexcoders@yahoogroups.com, Alex Harui [EMAIL PROTECTED] wrote: I spend a couple of minutes on this. The rules are that, when verticalScrollPolicy=auto (default), the verticalScrollBar is not factored into the measurements and overlaps content, otherwise it would cause the scrollbar ripple. The simplest change to remove the horizontal scrollbar is to set verticalScrollPolicy=on on the outer Canvas. That way the verticalScrollBar is factored in. Because the widths are preset in this example, it is safe to do that since you know the verticalScrolLBar has to be on.

[flexcoders] Loading Image Sequence into Movie Programmatically/Dynamically Generate SWF
I saw some posts on this topic and didn't see any solution to this yet. Is there a way to use Actionscript 3.0 in Flex/AIR to generate .SWF at runtime? I guess I can't call the mxml/as compiler directly. The problem I am having now is that I want to load an image sequence as a movie programmatically. At first, I got it working by loading each image with URLLoader whenever I want to play the movie, but the initial load time was just too much. Then, I tried appending all the images into one big bitmap and calling URLLoader once, but the 2880 bitmap pixel limit screwed me up. So now, I am trying to put each picture as a frame of the movieclip. My objective is to have a dead simple process for creating movie clips from image sequence, and a fast playback of the movie. I appreciate any suggestions or directions, thanks! -- View this message in context: http://www.nabble.com/Loading-Image-Sequence-into-Movie-%3E%3E-Programmatically-Dynamically-Generate-SWF-tp15261040p15261040.html Sent from the FlexCoders mailing list archive at Nabble.com.
[flexcoders] CustomComponent property refresh problem
Hi List,
I'm developing an application with custom components and custom Value
Objects in combination with the Cairngorm Framework.
It is a reporting application and the idea is to have a central TableVO
which contains the report data and several UI elements like a Datagrid
and several charts are attached to the TableVO. The TableVO object
resides in a Cairngorm Model Locator object and is [Bindable].
A snippet of my TableVO object:
public class TableVO extends EventDispatcher
{
public static var CHANGE_EVENT_NAME:String = tableVoChange;
private var __columns:XAxisVO;
private var __mapTableContent:ArrayCollection;
private var __chartValues:ArrayCollection;
public function TableVO(){
super();
}
[Bindable]
public function get columns():XAxisVO{
return __columns;
}
public function set columns( arg:XAxisVO ):void{
__chartValues = null;
__columns = arg;
dispatchEvent(new Event(Event.CHANGE));
}
public function set mapTableContent( arg:ArrayCollection ):void{
__chartValues = null;
__mapTableContent = arg;
dispatchEvent(new Event(Event.CHANGE));
}
[Bindable]
public function get mapTableContent():ArrayCollection{
return __mapTableContent;
}
}
The Datagrid and the charts are custom components which extend the Flex
Datagrid and Chart components.
My application runs fine but I have problems with filter-functions. The
filter function affect the property mapTableContent in TableVO and I'd
like to see the filter effect directly in my custom components.
This works fine in the Datagrid component but the chart components seem
to be not aware of changes in TableVO.mapTableContent, nothing changes.
I tried to find a hint in the documentation but I wasn't able to find
the reason why my code doesn't work.
What I would like to have:
* a filter function is applied to TableVO.mapTableContent
* my custom chart component gets aware of changes in
TableVO.mapTableContent and executes a method for redrawing the chart
Any hint is appreciated.
Regards,
Christoph
Re: [flexcoders] Re: How to deep copy an ArrayCollection?
this will work for just one level of depth. i mean, if your item has a reference to another object in the model, you will just clone the item not the object so you will have two items referencing the same object. i had this issue and developed a system for this. All my object can be serialized to xml and deserialized from xml. by the way xml generation process is recursive.(when an item's toXML method is called it also calls it's children' toXML methods) this give 100% copy. it may be seemed a bit hard, you may start with learning XSD (xml schema definition) by the way, i just realized that the same recursive approach can be applied using byteArrays. Stephen Allison wrote On 02/04/2008 01:38 PM: In my application I am using ArrayCollections to store data for series on a line chart. I need to be able to make a deep copy of these ArrayCollections so that I can make changes to the data in the copies without affecting the original data. IIRC you can write the whole lot into a ByteArray, which serialises it as AMF in memory, and then read it back out again. Classes in your array need [RemoteClass] in order to get correctly typed objects back. ie. var ba:ByteArray = new ByteArray(); ba.writeObject(yourData); var newCopy = ba.readObject(); Stephen

Been looking at the http://coenraets.org/blog/2007/10/offline- synchronization-using-air-and-livecycle-data-services/ example for using LCDS as an OCA built in Flex 3. Great example to get started; however, when we try to use multiple services in the same app we're getting some really weird results. On disconnect the Managed Collections are emptied automatically [while when using just the one service the app automatically reads/writes to cache].

[flexcoders] Re: Event Propigation
Thanks for the reply and apologies for the late response.
Unfortunately, your second idea may not be practical in my application
as it will only be certain modules listening for these events (what
modules listen to what events would be determined at load time as an XML
configuration file is loaded).
I have tried your other idea, setting the event listener on the module
as it is being dynamically created and then dispatching the event from
the parent, unfortunately that did not seem to work. Code samples below:
RootApplicationFunctions.as(script included on root most application
file so this would be the parent application)
* NOTE: This function is a couple functions down the chain, originating
from a loop which is iterating over the XML configuration file. It tells
the applications what modules to load. *
private function moduleLoadComplete(event:ModuleEvent):void
{
// The module itself as a Display Object.
var visual:DisplayObject = event.module.factory.create() as
DisplayObject;
// The module container.
var modContainer:ModuleWrapper = new ModuleWrapper();
modContainer.id = module_container + this._moduleIndex;
// Add event listeners to the modContainer.
modContainer.addEventListener(profileDataUpdated,profileDataUpdatedHan\
dler);
// Add module to the container.
modContainer.addChild(visual);
// Add module container to workspace canvas.
root_canvas.workspace_canvas.addChild(modContainer);
this._moduleIndex++;
}
private function sendEvent():void
{
dispatchEvent(new Event(profileDataUpdated));
}
I did know if it would be looking for profileDataUpdatedHandler in the
parentApplication or in the moduleWrapper as file itself, so at present
this function exists in both spots:
public function profileDataUpdatedHandler(event:Event):void
{
Alert.show(module container heard the event: +
event.target.toString());
}
RootApplication.mxml (this is the file which includes
RootApplicationFunctions.as above)
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:view=view.*
layout=absolute
width=100%
height=100%

mx:Script source=RootApplicationFunctions.as /
mx:XML id=OEMConfiguration source=xml/oemConfiguration.xml /
view:RootCanvas id=root_canvas /
mx:Button click=sendEvent() /
/mx:Application
As of yet, I have not been able to get this to work. If I click on the
button on the root, it does fire sendEvent(), but module being loaded is
not responding (technically it is the ModuleWrapper listening, but the
ModuleWrapper passes instructions to the module contained within).
I have other options available to me I suppose, however this is the way
I would like to do it because it seems like the cleanest way.

Hi Everyone,
I have been charged to architect a fairly large scale Flex

I have not worked with events too much, but I understand the default
three phases it goes through (capture,target,bubble). The

poll the parent for that data to get the new information.
Based on everything I have read, events don't propigate in that

then climbs back up). However, is it possible to make it go the
other
way? Can children hear events of the parent? If this is impossible,
does anyone have any thoughts or suggestions for an alternative to
my

One option would be to change the chart's viewable area, as in modify

This problem has to do with me NOT wanting to write 100+ reports to
generate 100+ separate xml files to access.
I need to track the metrics of several internal groups over the year
via
charting. I want to drill down into individual months (by day) and
--
maybe, days by hour. I also want to track into the sub groups per
month and per day-in-month for each of these groups as well.
The data is network event traffic and doing the queries live will
just
not work. Users wont use the slicing and dicing

[flexcoders] Re: Fail to apply UITextFormat to UITextField in custom Component
dan, thanks for your answer. I'm using device and/or embedded fonts,
but right here I don't really care about the fonts. I'm just puzzled
why the formatting doesn't seem to work for me. I'm using UITextFormat,
because of the options it gives me with anti-aliasing and measuring. A
I tried using TextFormat but that wont help. I did not look at styling
and skinning, so I'm not sure if the formats get overriden by styles
in a later stage by the framework.

[flexcoders] Re: newbie: pushing data changes back to server
Basically, to make any changes to the data in the datagrid you just need to make changes to the dataProvider you specified. Say, if it was an ArrayCollection, then you would just update the array collection. Then you would want to send the changes back to the server using an HTTPService, RemoteObject, or other call to the server and process the call with some server side scripting. Here's a few good tutorials: http://blog.paranoidferret.com/index.php/2007/08/24/flex-php-json-mysql-advanced-updating/ http://blog.paranoidferret.com/index.php/2007/11/02/sending-flex-data-to-php-using-xml/ http://blog.paranoidferret.com/index.php/2007/07/27/flex-friday-feature-datagrid-component/ Hope that helps, -- William --- In flexcoders@yahoogroups.com, andrew_sinning [EMAIL PROTECTED] wrote: I've been working with Flash in AS2 for quite a while, but so far I've only just worked through the tutorials in Flex.

Re: [flexcoders] AIR - including other files
First, you need to have the files somewhere within your source directory (well, it's easiest anyway). When you're building the release version, once you've entered in your information for the digital signing, click next instead of Finish. It will now give you a list of files and directories to include/exclude. Now, not all files can be included, but images and db files can. I tried including a swc, but it wouldn't let me, so I had to change the extension, then use the file API to have the application rename it back when I wanted to work with it.

[flexcoders] default Image dimensions
Normally, when using the Image class, if you omit the dimensions, Flex will default the image to its real width/height. However, I'm running into a situation in that Flex is defaulting the dimensions to 0,0 (if omitting explicit dimensions). Has anyone else ever encounted this issue? As for some general details of its useage, I'm instantiating a new instance of the Image() class (rather then using the mx:Image tag), and it's being used as private class variable in a custom container (based off the Container class). The image is being defined as a class variable and then instantiated with its source in the createChildren() method. Being as though this is a runtime image (and therefore won't know and won't be able to hardcode the dimensions), I'm having to listen for the image load complete event to detect what the dimensions should be, and then set them explicitly. This works, but I'd like to find out why the default sizing behavior isn't working correctly.
[flexcoders] Re: Event Propigation
Update
I was thinking that maybe the reason the below did not work was because
I was adding the event listener before the object was added to the

to workspace_canvas. Unfortunately that did not help. Updated function
follows:
private function moduleLoadComplete(event:ModuleEvent):void
{
// The module itself as a Display Object.
var visual:DisplayObject = event.module.factory.create() as
DisplayObject;
// The module container.
var modContainer:ModuleWrapper = new ModuleWrapper();
modContainer.id = module_container + this._moduleIndex;
// Add module to the container.
modContainer.addChild(visual);
// Add module container to workspace canvas.
root_canvas.workspace_canvas.addChild(modContainer);
// Add event listeners to the modContainer.
modContainer.addEventListener(profileDataUpdated,profileDataUpdatedHan\

this._moduleIndex++;
}

Unfortunately, your second idea may not be practical in my application
as it will only be certain modules listening for these events (what
modules listen to what events would be determined at load time as an
XML
configuration file is loaded).
I have tried your other idea, setting the event listener on the module
as it is being dynamically created and then dispatching the event from
the parent, unfortunately that did not seem to work. Code samples
below:
RootApplicationFunctions.as(script included on root most application
file so this would be the parent application)
* NOTE: This function is a couple functions down the chain,
originating
from a loop which is iterating over the XML configuration file. It
tells
the applications what modules to load. *
private function moduleLoadComplete(event:ModuleEvent):void
{
// The module itself as a Display Object.
var visual:DisplayObject = event.module.factory.create() as
DisplayObject;
// The module container.
var modContainer:ModuleWrapper = new ModuleWrapper();
modContainer.id = module_container + this._moduleIndex;
// Add event listeners to the modContainer.
modContainer.addEventListener(profileDataUpdated,profileDataUpdatedHan\
\
dler);
// Add module to the container.
modContainer.addChild(visual);
// Add module container to workspace canvas.
root_canvas.workspace_canvas.addChild(modContainer);
this._moduleIndex++;
}
private function sendEvent():void
{
dispatchEvent(new Event(profileDataUpdated));
}
I did know if it would be looking for profileDataUpdatedHandler in the
parentApplication or in the moduleWrapper as file itself, so at
present
this function exists in both spots:
public function profileDataUpdatedHandler(event:Event):void
{
Alert.show(module container heard the event: +
event.target.toString());
}
RootApplication.mxml (this is the file which includes
RootApplicationFunctions.as above)

As of yet, I have not been able to get this to work. If I click on the
button on the root, it does fire sendEvent(), but module being loaded
is
not responding (technically it is the ModuleWrapper listening, but the
ModuleWrapper passes instructions to the module contained within).
I have other options available to me I suppose, however this is the
way
I would like to do it because it seems like the cleanest way.

[flexcoders] mx:Tile changing its height unfavorably
So I have an mx:Tile element whose width is 100% and height is unspecified. I want its height to grow as needed as I addChild(uicomponent). (after it fills up the first row it will make a second row and increase its height). However, It uses up about half the width and when I add another element, its height doubles for no apparent reason. Quick ascii example: After two addChild() -- 00 00 -- After three -- 00 00 00 -- this leaves a large unused portion of my app right in the middle of the screen, and it annoying. Perhaps I am using the Tile component incorrectly? Should I be using some other component to accomplish this? Any help is appreciated. Seth

[flexcoders] Re: Fail to apply UITextFormat to UITextField in custom Component
Styles can override text formating when the parent of a UITextField is
invalidated, but only having some formatting overridden is a little
weird.
no, all of the formatting is overridden.
Functionality for setting format based on style is in the
UITextField class,
I think the function is validateNow()
thanks dan, that pointed me to the right direction. I traced
validateNow() in UITextField where the format is set using styles -
overriding all of the formatting that might have been applied using
UITextFormat. I did toggle styleChangedFlag to false and voilà - all
the formatting using UITextFormat were applied. Now I have the choice
to extend UITextFormat and to override validateNow() or just use
Styles for all the formatting and forget about UITextFormat, which is
probably the recommended way - just getting started with flex you see.
thanks again, solved.

For future reference, I asked about font type because embeding fonts
incorrectly could account for the described behavior (as I originally
understood it), and the rendering engine for device fonts (in very
few and
specific cases) also has its own quirks.

Re: [flexcoders] Databinding in component

Clicking the button will generate a collection change event, but will
not trigger data binding because the value of _dataProvider is not
changing (no assignment is being made to the _dataProvider member). If
you want to know when items are added to/removed from the collection you
will need to listen for events as follows.
public function set dataProvider (_dp:ArrayCollectio n) :void
{
_dataProvider = _dp;
//listen for collection change events, use weak references so we
don't cause a leak
_dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE,

RE: [flexcoders] Re: Event Propigation
You appear to be dispatching the event from the Application but
listening for it on a ModuleWrapper which is some descendant of the
Application. That's not how events work. Unless you use the capture or
bubble phases, you have to register on the object which is dispatching
the event. And if you do use the capture or bubble phases, you have to
listen on an ancestor of the object which is dispatching the event.

private function moduleLoadComplete(event:ModuleEvent):void
{
// The module itself as a Display Object.
var visual:DisplayObject = event.module.factory.create() as
DisplayObject;
// The module container.
var modContainer:ModuleWrapper = new ModuleWrapper();
modContainer.id = module_container + this._moduleIndex;

root_canvas.workspace_canvas.addChild(modContainer);
this._moduleIndex++;
}
private function sendEvent():void
{
dispatchEvent(new Event(profileDataUpdated));
}
I did know if it would be looking for profileDataUpdatedHandler in the
parentApplication or in the moduleWrapper as file itself, so at
present
this function exists in both spots:
public function profileDataUpdatedHandler(event:Event):void
{
Alert.show(module container heard the event: +
event.target.toString());
}
RootApplication.! mxm l (this is the file which includes
RootApplicationFunctions.as above)

/mx:Application
As of yet, I have not been able to get th! is to work. If I click on
the
button on the root, it does fire sendEvent(), but module being loaded
is
not responding (technically it is the ModuleWrapper listening, but the
ModuleWrapper passes instructions to the module contained within).
I have other options available to me I suppose, however this is the
way
I would like to do it because it seems like the cleanest way.

Re: [flexcoders] Strange behavior....
You are seeing correct behavior. See:
http://livedocs.adobe.com/flex/201/langref/package.html#Boolean()
If you want to do what your code intends to do you have to check for the
string true manually:
(variable == true ? true : false);

RE: [flexcoders] PopUpButton not working in AIR Beta 3
Jeff, This sounds like this bug: https://bugs.adobe.com/jira/browse/SDK-14470. Unfortunately, this bug was deferred for this release because we are at the end of the cycle, but, there is a workaround in the bug to reset the PopUpButton. HTH.

[flexcoders] ActionScript multidimensional Associative array question
Hello, I need to create a 3D array, first two dimensions are associative arrays and the 3rd one is indexed. Here is what I am trying to do: myArray[1992][February] -- this will generate an array of objects which will be used as dataprovider for my chart. BTW the number of elements are unknown, the number of Associative string are also unknown, so I do have to create the array dynamically. Please suggest or point me to an example. The example in http://livedocs.adobe.com was not enough for my inquiry. Regards

[flexcoders] generate unique colors for per-item fill
How do I generate a list of unique colors dynamically in AS? similar to how Flex does in default charts, except in a per-item fill scenario? CONTEXT I want to color code an Hlist of categories to match the dot colors in a per-item filled Plot Series. I have an arrayCollection dataProvider that is a list of categories [categoryid,category]. (number of categories is unknown/unlimited). I'd like to generate a unique color number corresponding to each category in the array and update that arrayCollection with the generated color numbers.[categoryid,category,color] I'd like to use this resulting [categoryid,category,color] arrayCollection as a dataProvider to a horizontalList (dynamic legend list) and a PlotChart per-item fill (Ifill) to color code the dots for each category. User clicks on a color/cat in Hlist, filters the dots for the selected category. Colors in the Hlist match the corresponding colors in the plotchart. I know how to color code the horizontalList, build the fillFunction, and do the filterFunction... but I don't know how to generate the unique colors (much like Flex does for the default colors in charts) in a per-item fill scenario. I'm assuming I'd loop through the arrayCollection of categories and update the color dynamically using some color generator? The colors need to be as unique as possible. It would be cool if I could somehow use Flex's built-in default unique colors for chart series in the per-item fill case? I could create a color column in the category table in the database, and store colors there for each one, but seems to me that AS might be a better approach. Thanks! Don
