Flex 3 makes accessibility for the standard components quite easy. However, when creating ActionScript custom visual components, things get, well, murky. I haven’t found too many posts at all about this out there, so I’m going to document the work that I am doing right now, so that myself and others could possibly benefit from it later on.
Here are the links I have found so far. I’ll post more of my discoveries as I am able.
