[flexcoders] Matching colors between Photoshop and Flash/Flex
So I'm having some trouble matching colors between Photoshop and Flash. As I understand Flash is sRGB, and I believe my photoshop file is sRGB (not totally sure). However, obviously something is off because the colors aren't matching. I can't seem to find any information about matching Flex and Photoshop colors. I'm seeing problems with the hex values I pick up from the interface as well as an image I export. So what's the secret sauce? I'm sure this is simple, but I'm new to this matching color junk. Thanks Charlie

[flexcoders] Getting started with Fluint
I'm trying to setup my project to use Fluint for unit testing, and I've read the documentation. I'm doing an AIR app so I've trying to test my sqlite db layer, and model objects using Fluint. However, the details of how get a simple test running are very vague. There's a whole discussion around defining your testsuites in a module that the Air runner then loads in order to execute your tests. Sounds good, but how do I get that running in FlexBuilder 3? I've defined my module and I see in bin-debug my module's swf. So how do I run my tests? Can I easily setup some run/debug configuration to fire off my unit tests? Is there something in the fluint swc that I configure as another Application? Thanks Charlie
Re: [flexcoders] Re: Passing data providers to drop-in item editors/renderers
You can access the instance members of your surrounding document using a
special property *outerDocument* from within the mx:Component tag when
using inline renderers.
mx:Component
mx:ComboBox dataModel={outerDocument.choices}/
/mx:Component
outerDocument allows you to access any special data or functions you've
defined outside the mx:Component. It works nicely when you need to inject
data/behavior that is not associated with the data field from the model.
Remember itemRenders/editors are unique per row so there's no way to inject
data into them since you're not in control of constructing them. This is
the only way I've found around this little snafu.
If you don't use inline components you can always wrap your custom component
inside an inline and pass data form the outerDocument in as properties to
your custom component thus keeping the code nice and straight forward. No
tricky code.

Basically, I just need to supply a list of Realm objects to my itemeditor

Re: [flexcoders] Re: Working with images of varying proportions
I seem to remember encountering this problem as well a while back. I think
the problem is that you are accessing the loader's info before the loader
has a chance to finishing loading them.
If you're inside complete event dispatcher you might try callLater() and see
if that works. I wish I could remember the solution, but it's something
like that.

they cause the function to stop execution when executing the Flex app

[flexcoders] Performance and UI failing to update?
I'm writing an AIR application where I have a very long operation that
I need to run in the background. I know Actionscript doesn't have
threads so I'm trying to simulate that using cooperative multi-tasking
by breaking up my job into smaller pieces. I'm basically trying to
parse an XML file, iterating over the nodes in that XML document,
parsing the file that node refers to, add an entry to the SQL lite DB.
The parsing of the XML is done separately from the iteration, and
each iteration of the loop over the nodes is done using
UIComponent.callLater(). So my algorithm looks pretty close to
something of this form:
function doIteration( currentIndex : int, totalIndex: int ) : void {
var current : Object = objects[ currentIndex ];
doSomething( current );
callLater( doIteration, [ currentIndex + 1, totalIndex ] );
}
My expectation is that by using callLater that will allow my UI to
paint and update between each iteration of my loop. However, that
doesn't seem to be the case. When my application starts this process
it updates very infrequently, and freezes most of the time. I can put
trace statements in my loop and see that it's processing loads of
files very quickly, but the UI never gets updated.
How does Flash behave when it's under a load like this? It runs as 12
frames/s, and I know that callLater is done at the end of each frame.
What happens if that process run is longer than 80ms/frame (1000ms/s
divided by 12 frames / s)? Does it ever catch up?
Thanks
Charlie
Re: [flexcoders] Performance and UI failing to update?
Tracy,
Before I started parsing the file it actually worked simply iterating
over the files and adding them to the DB without processing them.
After I started parsing the files I started getting this halting of
the UI.
Do you have any more details about how your technique was different?
Maybe a quick excerpt of code could help clarify your technique.

Manish,
Thanks that's more like the info I was looking for. Just some details
as to how Flash events and frame rates work in relation to
callLater(). Using a timer has one distinct advantage that you can
control how fast something is running where my technique ran every
frame (or so I thought). Right now the processor is being killed so
maybe if I use a high cycle timer I can control that better.

You should consider a timer-based approach rather than a frame-based one.
I remember looking at this library and thinking it was nice:

Re: [flexcoders] Re: AIR SQLLite, ints, and NULLs
Ok thanks Johannes. Very good point. Number's can't really be NULL either.
However, it just so happens that NaN is interpreted as NULL to the datatype
conversion layer in AIR and it just happens to work out. Maybe this slight
difference between NaN and NULL doesn't really matter, but it's good to know
that it exists.
My temptation is to write a real object that encapsulates int's as a true
Object data type that can really be NULL, but the draw back here is that it
would be incompatible with AIR's handy databinding (itemClass on
SQLStatement since AIR will convert database integers to Numbers instead of
my abstraction).
I guess more investigation is needed in these matters.

Re: [flexcoders] Re: AIR SQLLite, ints, and NULLs
Thanks Amy, but I was really asking for what I can use as a substitute data type for an int since you can't have NULLs for an int. So far from what I'm finding is I can use Number in place of int and also get a null value for a Number into the DB. At least it seems that way so far. If I change all of my int's to Number's then I start getting NULLs as expected for values that are unset. So I guess I really trying to validate that fact with other Actionscripters out there to see if this is acceptable or if not is there a better option. Can I use Number place of int and not run into any problems down the road?

[flexcoders] FileReference's DataEvent.UPLOAD_COMPLETE_DATA event being dropped randomly
I'm having trouble getting a DataEvent.UPLOAD_COMPLETE_DATA event when uploading many FileReferences. It randomly drops events, but I get all of the progress events, and Event.COMPLETE.

I'm aware that UPLOAD_COMPLETE_DATA is not sent if the server doesn't return any data, but I'm sending data for all of these uploads (because it all traverses through he same code). So if I get even one callback I should get all of them in theory. My first theory was that my server process was taking too long and flash timed out the response so I offloaded what was taking so long, but that didn't improve anything. Any idea what's going on here? Any other ideas on what I can try? I'm using a Ruby on Rails server backend. Charlie
Re: [flexcoders] FileReference's DataEvent.UPLOAD_COMPLETE_DATA event being dropped randomly
Thanks Jeff. That just might work for what I'm doing. What a pain in the ass, but your suggestion is pragmatic. I'm sure others have encountered this problem. Any explanation about why Flex/Flash is not upholding it's end of the bargain? Is it just a simple issue of Flash's URLRequest timing out waiting on the serverr? My server is responding in about 500ms on the low end at around 200ms on the upper end. But, it still just drops some of the requests.

[flexcoders] Getting an ItemEditEnd event to fire from a customer itemEditor (Focus?)
Hi, I have a customer item editor that handles a 5 star rating system. If the user clicks on the component it will rate it 1-5 stars. I've gotten everything working except I can't get the DataGrid to fire an itemEditEnd event when I click on the component. I figured it would work similar to CheckBox, but I think my missing piece is that CheckBox is focusable where my HBox with 5 Image components is probably not. What actually triggers the DataGrid to know when an editor is done editting? Should my customer editor fire the itemEditEnd event? Or is that DataGrid's responsibility? If it is, what event can I fire to force DataGrid to fire it's ItemEditEnd event? Thanks Charlie
[flexcoders] Stump the Flex Nerd: Getting reference to the set method of a property
Ok, I think I've got a pretty difficult question here. I want to the setter method given a string containing the name of a property. With normal methods I can always do something like obj.myFunction to get a reference to that function, then I can invoke that function with a func.call(). However, if you do obj.someProperty that calls the get method. I already tried obj[ propertyName ] which returned null so that's out. It's almost like you need another language feature. obj-property= and obj-property for ( reference to setter and getter of this property). Charlie
Re: [flexcoders] Stump the Flex Nerd: Getting reference to the set method of a property
Well that was a quick answer thanks. Too bad you can't do this :-( I
noticed in my debugger if I drop a breakpoint inside the set property
function it reports the name of the function as set property with a
space. I haven't tested if obj[set property] would really return that
function or not, but I guess not.
I'm trying to save myself extra typing by going meta with my framework.
I'm trying to map the results coming back from say a RemoteObject onto a a
model's property inside the object receiving the server's response. It's
really just trying to save myself the extra work of writing a bunch of tiny
little functions that just do a property set. For example:
var token : AsyncToken = parent.getAllUsers( orderBy );
token.addResponder( new AsyncResponder( generateEvent(usersLoaded, users
), generateError(usersFailed), token ) );
return token;
The meat of this example is the generateEvent() and generateError()
methods. These methods simply return a listener function that will generate
the event specified in the first parameter, and in the case of generateEvent
it will assign the results from the server to the property users. This
allows the model to load the data form the server asynchronously, then when
the results arrive back it fires a domain level event so the Controller can
grab that event and respond to it, or just use simple Bindable on the
property to update the view if it's a simple response.
My work around is the following:
var token : AsyncToken = parent.getAllUsers( orderBy );
token.addResponder( new AsyncResponder( generateEvent(usersLoaded,
function( result : Object ) : void { users = result as ArrayCollection; }),
generateError(usersFailed), token ) );
return token;
It just saves me from having to inline an anonymous function that sets the
result onto the property. Makes it slightly cleaner. I'll probably
refactor the whole addResponder mess so that it's even less messy, but I
won't be able to reduce the inline function needed to route the result onto
the property.

Re: [flexcoders] New to flex, wonder why one works and the other doesn't...
Right. Image is a UIComponent, and TextArea is a UIComponent.
UIComponent's can't contain other UIComponents without being a
subclass of Container or implementing the IContainer interface. Not a
simple task.
addChild() is defined in DisplayObject which apart of the Flash API
not the Flex API. BitmapAsset is a sublcass of DisplayObject and not
UIComponent. So you can add it to the text area directly using this
code:
var img : BitmapAsset = new imgCls() as BitmapAsset;
img.x = txtArea.mouseX;
img.y = txtArea.mouseY;
txtArea.addChild( img );
Now, try that out, and you'll start to see some issues that you'll
have to asess if this is going to work for what you're trying to do.
Since the bitmap is not apart of the document in the TextArea you are
going to get clipping or scrolling. If you want to do that you'll
have to get really dirty with the TextArea API. Probably even
ditching TextArea altogether and writing your own, or modifying rich
text editor.

Re: [flexcoders] Drilldown ideas
I think you're asking what's the best UI metaphor for displaying hierarchal data from a dataGrid. While popup windows are cheap and easy. This work well if your user will be edtting the data once they see it. The Ok-Cancel metaphor on the popup window makes editing easy to use. Adding editing with these other options can be difficult. However, I think navigating around in data they are pain, plus the pop always is smaller than your screen real estate of your main window. I favor more a fluid UI by dividing the UI into the dataGrid on top and the content on bottom. Click a row displays the data in the bottom panel. You can orient the two areas anyway you like. Left and right if your data lends itself to being displayed easily that way. But, with tables they always seem less cramped if it's a top bottom orientation. This way your users can quickly navigate through the data and see the content with one window. If the bottom portion doesn't have enough space. Surround your table in a tab UI, then allow them to open up the content in a sibling tab so that they have all the screen space they need. And, that allows for a quick bookmark like work flow allowing the user to refer back to previously found objects. TreeTable grids work if the columns of the table match the columns you'll display when you drill down on a row. If the UI shown for drill down has different data requirements than the table's you'll find it too limiting or akward to display other types of data in the table. Ultimately, TreeTables can limit your ability to modify the UI in the future.

Re: [flexcoders] Scaling via Streaming???
Streaming is the ability to jump around a video stream without having to download the prior content. The user clicks play and then jumps 1 hour into the video. Streaming will allow you to jump to the hour mark without downloading the first hour. You have to use a special server to do this though. You have two options Flash Media Server (commercial and it starts at $5K and goes up depending on how many clients you have), or you can try Red5 server (open source). Red5 team has done a heck of a job reverse engineering rtmp protocols, and figuring out adobe's proprietary code, but it's still pretty early on and in beta. The other alternative is progressive downloads which means you download just a little bit of the video and start playing it once you have enough that won't cause a skip in playback. The idea is that if you give the downloader a head start he can continue to download the video fast enough that the playhead won't catch up to the video being played. To contrast this with streaming it means that if you haven't downloaded the the first 1hour you can't jump past it. You can only jump around in the portion you have downloaded, and the download progresses linearly (i.e. it downloads the 1st hour, the 2nd hour, etc ). This is the youtube approach, and it doesn't require any exotic technologies to accomplish this. A plain ole web server is all you need, and properly encoded video. (i.e. the meta data in the video stream that tells you how long a video is, etc has to be located in the front of the video stream). Most encoders will move that data up to the front for you. Personally, streaming I think sucks from a user's experience perspective. With streaming you can't cache the video that you download. Once the play head has passed that block rewinding is treated as another request for a different part in the stream so that means back to the server and wait while it buffers up the request. There's a lot of hurry up and wait with streaming that makes it worse that progressive downloading. Plus if you don't need to jump around in the stream then it's not worth it to you, and you get the crappy experience with it. I think what you want is a combination between the two which there is no just plug and play technology that satisfies what you want. But, if you cut up your streams along smaller boundaries (i.e. between the interactive parts) that would allow you to do progressive download on video they currently want to watch. When the interactive part starts, then you download the next segment they want to watch. Provided you can fetch that segment relatively quickly then the user will only have to wait say 5s before the next portion starts. If you really wanted to get fancy with it you could download all possible next scenarios while they are watching the current segment. As for can 36 students simultaneously watch/download the episode over a DSL. I can't say. But as a test, try getting those 36 students to download the same video from youtube and see what happens. You're using a nice P2P distributed model which is going to help you a lot since students at a location won't need to go out the DSL to get episodes another students has already downloaded.

[flexcoders] Netstream.play() arguments and caching video
Hi, I'm trying to download a video up front and cache it in memory before playing it. I understand how to use the Netstream.play() and passing it a URL. However, I want to download a video stream up front before playing it and cache it either in memory or the filesystem (I know this is probably not possible). Then at the right time pass that cached copy to the netstream to play it back. The documentation says play() can take several args, of unknown type, but they don't really explain what are all the possible types that can be passed. And, the examples only show it passing strings to urls. The docs do say you can tell it a local file, but I haven't seen any examples of that. Anyone have any information on how I could do this?
