[flexcoders] Re: how to show a preloader (loading spinner) when loading images in a flex app.
Hi i tried using states to archive this but i dont know how to listen for
completion of image loading. this is what i have so far.
mx:Canvas width=75 height=75
controls:SuperImage width=75 height=75
source=assets/homeprofile_pics/{data.img} borderStyle=none x=0 y=0
creationComplete=imgLoaded(event)/
mx:SWFLoader source=assets/wait.swf x=29.5
y=32.5 id=swfloader1/
/mx:Canvas
i put the image and the spinner.swf in a canvas, the create another state where
the spinner is taken out.
mx:states
mx:State name=remove_loader
mx:RemoveChild target={swfloader1}/
/mx:State
/mx:states
then i call a function to change states once the image is fully loaded
private function imgLoaded(event:Event):void{
currentState = 'remove_loader';
}
this doesn't seem to work. any help?
[flexcoders] Re: Custom ItemRenderer still not working...
Well, I found a work-around...
I added the following code inside my ComboBox ItemRenderer:
override protected function focusInHandler(event:FocusEvent):void {
listOfFees.refresh();
}
For some reason, with this in there, you have to double-click on the combo box
to open it, but the drop-down shows the correct data 100% of the time. Good
enough for now.

Re: [flexcoders] Flex Builder 3 - A little to be desired [1 Attachment]
I have not filed a bug yet because i dont really think im good enough to technically describe the issue. When i went to help new bug i just got a page saying the module is missing or deactive on jira. The best way i can describe it in both FB3 and FB4 is that the actionscript editor does not notify FB that a change in the editor has been made. I dont know if i can attach images to this mailing list but the attached screenshot shows the issue. Joint2 is invalid so i got a runtime error in red. I then commented out the offending line and resaved it but still the problem persists. The screenshot shows the offending line of code along with its error AFTER i have hit save. Note that this is a completely seperate project to my first email. Running FB2 and FB3 under 32x never gave me any problems, and if it did, not with enough frequency to be noticible in the 2 years i used them. Running FB3 under VISTA Home 64x AMD 64 has this issue Running FB4 under 7 Ultimate 64x Intel i7, i5 has this issue It seems there is an inherited bug somewhere which effects 64x OS Windows or architecture.. When googling this i found little so if you do experience this issue and can let describe it well, please reply with details. As far as im concerned even an option to tick to force a clean on save would save alot of hassle. Also is there any keyboard shortcut to clean? Cheers.

[flexcoders] How to navigate up when dealing with the class path?
This might be a stupid question. I have an /assets/ folder which contains a Fla. In this scenario i need to hookup a package /assets/assets.fla /assets/assets.swc /assets/assets.swf /src/code/SomeCode.as If assets.fla needs to extend SomeCode.as then how can i set the class path or is this not possible? Both my Actionscript project and my assets.fla need to reference SomeCode.as but i tend to use a folder outside of my src folder for the purposes of non-as files. The reasoning behind this escapes me. Cheers,
RE: [SPAM] [flexcoders] Re: Custom ItemRenderer still not working...
Refresh() is intended to re-apply a sort of filter to a collection. If it
is working in your case it is a side effect.
I couldn't find your previous post to look at the code, but I still suspect
recycling issues. For a combo box, you have to do two actions on set data
(actually in commitProperties, of course). You must re-assign to
dataProvider, and you must set the selectedIndex (you can only use
selectedItem if your items are simple strings or numbers). Are you doing
both of those things?

RE: [SPAM] Re: [flexcoders] Encoding XML Character Entity References *properly*
As far as I know, there is not built-in way to do this. There are many different solutions, including tricks with xml, and a base 64 encoder that apparently does this as a side effect, and I saw one manual replacement class that looked very complete.

[flexcoders] rendering HTML markup in AdvancedDataGrid
I am considering using an AdvancedDataGrid in hierarchical mode but am not sure it can do what my app needs to do, or if it can, whether the approach will be efficient--execute quickly and use up a lot of memory. I haven't worked with the AdvancedDataGrid before. The grid will look like this: [v] Category A [v] Title 1 * passage one blah blah blah * passage two [v] Title 2 [v] Title 3 . . . [v] Title n [v]Category B [v] Title 1 [v] Title 2 [v] Title 3 . . . Title n etc etc When the user clicks on a Title node to expand it, some passages excerpted from the corresponding document would be fetched from the database, already formatted as HTML like this: span class='foo'this is an excerpt span class='abc'100 to 1000/span characters in length/span. A style sheet must control how the css classes in the passage excerpts are rendered. The grid might have as many as 100 rows, and each row could contain a couple of paragraphs of html text. Up to 1K each, but more typically around 100-200 characters. If I create an item-renderer using TextArea, will 100 TextAreas be created if the grid has 100 Title rows even if only 3 titles are expanded by the user?

Thanks for the reply, Tracy, about the ItemRenderers. +1 on the htmlText warning. I've used the htmlText of the TextArea in an AIR app, which I'm converting from local DB to webservice mode now. The html rendering in Flex of the sort of html markup example I gave below is better than bad but is far from rich. Adobe gets a very low passing grade from me on its htmlText + CSS rendering in Flex. I don't need typographic control (kerning, ligatures, etc) but I do want support for basic CSS-- I could never get padding and margins to work. Font-family, bold, italics, font-size do work.

Re: [SPAM] [flexcoders] Size of an application
In my experience the smallest app using the flex framework weighs in at about 120KB. I expect that will get bigger with each version iteration. The size of your app will depend on what parts of the framework you are using. eg, the charting classes add about 100KB to your app if you use them. If size is an issue for you then you need to carefully look at what you include and perhaps consider using modules to split your app up a bit into pieces you can lazy-load.

Re: [flexcoders] Size of an application
I've seen online Flex apps range from 500k to 9MB without RSLs. Generally speaking, Flex app size is no longer an serious issue. A SD YouTube video can be 50MB and the user doesn't even notice the bandwidth. It makes sense to optimize in extremely large distribution (i.e. Zynga serving 30M+ apps daily) but not so much for small scale. -radley On Feb 6, 2010, at 2:46 PM, Christophe wrote: Hello, My application has a size of 900 Kb.

[flexcoders] Record audio to the hard drive
Is there a way to record an audio stream (microphone stream) to the users hard drive and THEN upload it to the server. I don't want to stream it to a server.
Re: [flexcoders] Adobe technical support dropped for Flex 3!
I really doubt that is true. Flex Builder 3 is the only official version. Flex 4 is still pre-release. Try again and see if you can get their response in writing.

I am very disappointed as I just bought Flex builder this week after I carefully evaluated the product during the trial period. I had an issue activating my product, and needed support to remove some conflict with the trial version that did not disappeared even after uninstalling and deleting completely the trial version. Customer Service was very nice but no technical support was offered. That shows the commitment of Adobe to this product.

Re: [flexcoders] Re: Custom ItemRenderer still not working...
Maybe Tracy can figure it out from just the renderer code, but I think I need a
complete (but small) test case with some sample data.
The only thing I see that looks unusual (besides calling refrehs() is setting
both selectedItem and selectedIndex. One should be good enough.

Refresh() is intended to re-apply a sort of filter to a collection. If it
is working in your case it is a side effect.
Yeah, I figured as much. I noticed that if I opened then closed then re-opened
the drop-down, the data would sync itself properly. Adding this refresh()
statement was a way to force that to happen -- the user clicks on the combo
box, the refresh happens (forcing the box closed), then the second click opens
the drop-down with the proper data... Total hack-job, but it works.
I couldn't find your previous post to look at the code, but I still suspect
recycling issues. For a combo box, you have to do two actions on set data
(actually in commitProperties, of course). You must re-assign to
dataProvider, and you must set the selectedIndex (you can only use
selectedItem if your items are simple strings or numbers). Are you doing
both of those things?
Here's my code as it stands right now. Thanks for taking a look:
