creating a user defined type

[Nikhil Kadu]

Hi Everybody,

How can I create a user defined class like nsAString and make it
available to idl file?

for eg. if my defined  class is 'nsFoo' then my idl file should look like:

#include "nsISupports.idl"
[scriptable, uuid(AB6F946A-0E56-4120-A020-2DC2E6AC7E12)]
interface nsIXPDBC : nsISupports
{
    nsFoo myFunction(nsFoo);
}

As far as I know u just have to define the class and its methods and
create a static library. No need of making any xpcom component. But how will the idl file know that nsFoo is a user defined type?

Thanking you,
Nikhil Kadu
