[RT] DPI dependent code was. Flex: New user interface design

I am all for it. I have implemented that for JavaScript before. My 
problem with the javascript implementation is to make it "easy". In 
other words: Without a "id" it is not possible to implement a generic 
ID. I have started with a implementation of JavaScript Modules but 
haven't had time to finish back then [1].

Martin.

Yeah, completely experimental code.

It does following things:

  * It replaces the embed codes in the html without id and with the same 
url as the swf that is running to
     embed codes with a proper id
  * It allows to create "JavaScript" code that receives directly a 
reference to the embed code it comes from
      (important if you have more than one Flash running on the same page)
  * It automatically takes care of error handling

What is your script trying to do exactly? I see it handling divs and
rewriting the Flash div for some reason? I'm not really sure what the .as
and .js file are working to do together. I guess I might have misunderstood
what you wanted to do with the JS bridge you originally mentioned to Erik.
Do the browsers give a more accurate value for the dpi? I haven't tried
querying for that value in any projects yet.
