Oh, my understanding is as follows. I think Adobe's intent is to support IA2 on Windows, and possibly ATSPI on Linux, and the Apple Accessibility Protocol on the Mac. I am not sure about the platforms other than Windows, but Adobe Flex and Flash are intended as cross-platform technologies, so that would make sense if accessibility was also to be cross-platform. As far as I know, Adobe chose IA2 over UIA. I think the latest UIA now includes bridges between UIA and MSAA in both directions, so an assistive technology client might still get accessibility support through UIA, but it would not be more than what is automatically translated from IA2 to MSAA to UIA, as far as I know.
Feel free to continue to discuss, and I hope others join, too. I think that Flash is a popular enough and pervasive enough technology area that, despite other frustrations with Adobe, I think we should try to take advantage of accessibility APIs that they say they have now implemented.

Jamal, Right right, but what I am saying is what interface will it be exposed through? You mentioned that MSAA is a subset of IA2, and in a way that's right, but even the subset features could be exposed via some other MIDL defined thing, right? So for example, to be quite technical, what function calls are being used to consume the information? The reason I'm wondering is this. Does this then mean that differing amounts, levels, and paradigms of accessibility are available into flex dependant upon the hosting application/process? For example, UIA has what, 28 or so roles that it can expose, and then compossits of any of those, whereas IA2 has a differing amount.

Hopefully, however, this could inspire others to go further than a fruit basket program with more sophisticated apps that took better advantage of IA2. I am still trying to understand this, but think there are different ways of running a Flex/Flash app, some more embedded within an HTML page and others more in a separate Flash window. I want to experiment through this process in learning the accessibility implications of different approaches. My understanding is that, with IE, the Flash Player is an ActiveX component that uses COM, whereas in most other browsers, including Firefox, it is a browser plug-in with some other binary interface (. I don't know more than that at this point. Jamal On 4/9/2011 11:49 AM, Sina Bahram wrote: > Jamal, are you thinking then that it will work via firefox?
