Re: [flexcoders] Air App loads swf loads image
If I can guess, then, probably you've loaded the SWF into the same domain, and if the URLs were relative to the loaded SWF they become relative to the loading SWF. Does it make sense?
Re: [flexcoders] Air loading Swf loading image
When you embed an image, the path is resolved relative to the file, where you put the Embed meta. If you load it, the path is resolved relatively to the file that loads an image.
Re: [flexcoders] Air loading Swf loading image
Julian. That's really not so relevant... if you embed an image, the image goes inside SWF, when you load it, it remains outside of the SWF, just lives somewhere on the HD. When loading, the way you load a SWF may affect the how the player will resolve relative URLs. I believe, that if the SWF is loaded into the same application domain as the loading SWF (especially, if that SWF was loaded using Loader.loadBytes()), there's no reason to think that URLs should be resolved relatively to the loaded SWF original domain simply because it may not even have one.

[flexcoders] DataProvider in AdvancedDataGrid itemRenderer
Can someone tell me what's wrong with this code? It generates the error:

List exists, but it seems like the scope of the DropDownList can't see
it? I've seen other example like this...how can I bind to the
dataProvider on the list if the property/var lives in the parent
container?

[flexcoders] How to display a LARGE dataset of images
I have a request to create an application that allows up to 20,000 images to be uploaded and displayed on a component using a DataGroup using a TileLayout. It starts out displaying the images 10px x 10px, then, as you mouse over it, it explands to 50px x 50px. The application starts by displaying a logo taken from a single image, then as people upload their images to specific places, the logo is replaced. As you can imagine, the application crashes if I go above 1000 images. Any way to do that and not have it blow up?
Re: [flexcoders] How to display a LARGE dataset of images
Load them and draw to a single bitmapdata and then unload? Anyways, just out of curiosity, what kind of application would need to display that many images at once?
Re: [flexcoders] How to display a LARGE dataset of images
One of those 'community' photo wall type apps. Do you know of an example of your solution or what I should google. Thanks!

Re: [flexcoders] How to display a LARGE dataset of images
Just have one Loader and one Bitmap (or probably 16 or about that number in the second case). When you handle the load complete you get the loader's content and draw it to the bitmapdata, remember where it was the last time, load next image, draw again and so on... However it will work, I would imagine that it will take some time to load all the images... I still don't understand why would anyone want to view so many images simultaneously... Can you maybe convince the customer that seeing 2 images at once isn't the best user experience? I mean, what will they see on an image 10x10? you won't be even able to tell if that's a man portrait or a flowers pot...
Re: [flexcoders] How to display a LARGE dataset of images
how about an image pool - so you cache a number of images - better if you have
thumbnails available to load otherwise, i would recommend resizing the bitmap
data ...
2 at once is a lot - if it's a list type thing you want, I found Spark
lists with a custom item-renderer worked well with pools of images - especially
as the spark list uses pools of object for it's list items - so you wont have
to load all that at once.. your app should load the images as required... it's
what i used for the AIR app @ http://gedit.kurst.co.uk/ - but - well,
definitely not tested for so many images.
MXML List I used :
s:List
id=imageList
itemRenderer=com.kurst.galleryEditor.skins.DataListItemRenderer
dataProvider={galleryData.imageCollection}
creationComplete={dataController.imageList = imageList}
left=10
right=0
top=0
bottom=0
dragEnabled=true
dropEnabled=true
dragMoveEnabled=true
borderVisible=false borderAlpha=0.0 contentBackgroundAlpha=0.0
!-- ++ --
!-- DATA - IMAGE LIST LAYOUT--
!-- ++ --
s:layout
s:TileLayout columnWidth=130 rowHeight=130
horizontalGap=10 verticalGap=10 /
/s:layout
/s:List
Item Renderer:
http://kurst.co.uk/transfer/DataListItemRenderer.mxml
And object pool:
http://kurst.co.uk/transfer/DataListItemController.as
won't compile but might give you and idea, the only thing i did not build into
the pool was a size limit.
code is is not commented ( sorry ), but might help... and not tested for 2
images... but that should be the concept.
good luck

Re: [flexcoders] DataProvider in AdvancedDataGrid itemRenderer
Try {outerDocument.list} or {parentDocument.list} ?

[flexcoders] Flex 4.1 , automation_spark.swc and OSMF 1.o issues
Hi ,
There seems to an issue when trying to compile in the automation libraries
into a Flex 4.1 app that also includes the OSMF1.0 swc.
I get the compiler error:
Description Resource Path Location Type
1046: Type was not found or was not a compile-time constant:
DimensionEvent. Test Unknown Flex Problem
The app is essentially a basic empty mxml application, with the OSMF 1.0 swc
added to the build path-libraries and the following mxmlc arguments:
-include-libraries ${flexlib}/libs/automation/automation.swc
${flexlib}/libs/automation/automation_dmv.swc
${flexlib}/libs/automation/automation_agent.swc
${flexlib}/libs/automation/automation_spark.swc
Is there some way to workaround this ?
TIA,
