This seems not to be the case however, as mentioned here (by Adobe too):

read the comments:

“SWCs generated in Flash, especially with the Flex Component Kit for
Flash CS3 (http://labs.adobe.com/wiki/index.php/Flex_Component_Kit_for_Flash_CS3)
work in Flex. SWCs made in Flex usually will not work correctly in Flash. Specifically,
you cannot get the Flex components to work in Flash by packaging them as SWCs, or by
trying to use the framework.swc that comes with Flex.

So while there is compatibility, it is effectively one way at this time.”

I managed to get automate the whole patching of a Flex SWC to work in CS3 – I’ve gotten LivePreview working too.

But whenever I run from within CS3, any components I dropped in are dropped from the SWF. Strangely, inspectable parameters *and* LivePreview works… all very bizarre.

I should mention. LivePreview works – but the DiplayObject size information is completely lost, and everything drag-drops at 500 x 375.

I’m going to experiment with some very simple visual only classes and see whether with the aid of a hex edit I can find out what is going on. The ABC dumps for library.swf are a little different from CS3 and Flex:

—- Flash
size [Rect -480 -840 1160 800]
frame rate 12
frame count 1
FileAttributes 4b 0%
SetBackgroundColor 3b 0%
undefined 11b 0%
DoABC2 792b 1%

—- Flex
size [Rect 0 0 10000 7500]
frame rate 24
frame count 1
FileAttributes 4b 0%
77 (invalid) 458b 0%
EnableDebugger2 31b 0%
DebugID 16b 0%
ScriptLimits 4b 0%
SetBackgroundColor 3b 0%
ProductInfo 26b 0%
DoABC2 7503b 10%

Disappointing so far. Flex exports share ready classes but not shapes. Flash exports share ready shapes and no classes.

Pfft.

“It isn’t completely clear from your post if you’re creating a component to use in Flash or simply a class that can be used in Flash.”

Derek, I was creating a component to use in Flash. It served as a base class just like UIMovieClip does but I wanted it to show up in the component palette just like UIMovieClip does. I have found out that you can simply point an FLA at a SWC in the classpath and use classes in the SWC, but in my case we were creating a MXP for 3rd party use.

Going the AS3 project route wasn’t an option. See what I wrote above. I realize I wasn’t very clear in my post regarding my exact situation. My goal was to create a MXP which contained a SWC that I authored in Flex (for the reasons stated above). I’m pretty sure this is how Adobe created the SWC in the Flex Component Kit for Flash.

I’d like to look at this, I’ll email you. I would think we could get this to work.

Nils said the compiler flag worked for him. I’ll give it a try with the project I originally used this approach for.

Same thing here, I can’t make it work for Flex 3.0. Do you have anything new on that issue?

Thanks
