You'd embed a Flex app in a web page just as you would any Flash content,
basically. Flex compiles to a SWF file, which runs in the Flash player. As long
as facebook allows you to add Flash content, you should be just fine.

FYI- a Flex "widget" usually refers to a stand-alone desktop application
created in Flex, but compiled to run in Adobe AIR, not Flash. Hence the
confusion in terminology. I looked at the url you provided and it is simply a
SWF file. They are simply saying it can be embedded in a web page which
contains other content, and this is true.

Just remember: Normal Flex applications run in a web browser, AIR applications
do not. But they both are created in Flex.

Thanx a million! I've never looked into programming at any level & I recently
started studying XML code so your last email was greatly appreciated. Its truly
a vast hidden universe from just UI's & doing graphic design....Thanx
