Is playerglobal.swc the only dependency of the Flex SDK needed to build a swf file?

I am trying out FDT and it has several bundled SDKs. Some of them are labele开发者_JS百科d pure and only contain the playerglobal.swc. Is this to compile ActionScript 3 only swfs?

Yes.

Also keep in mind that AS3 Project Types will also have some Flex SDK SWCs referenced as well, e.g. the 'flex.swc' and 'core.swc'. This is because for certain types of metadata embedding, you'll need those extra Flex classes.

In these cases, don't worry about using the 'Flex Framework' and getting a very large SWF. These classes are very lightweight and IF you use them, they will be small.
