Using <java.lang.Class>:forName with define-simple-class

[alex mitchell]

I'm trying to get a kawa-based application to be aware of MacOS application
events such as Apple-Q, and would like to avoid having to change my source
code when compiling on other platforms. I've got this working except for one
problem. When I define a class implementing ApplicationAdapter as follows:

(define-simple-class <my-application-adapter>
(<com.apple.eawt.ApplicationAdapter>)
...)

everything works fine on a Mac, but I'm assuming I won't be able to compile
this on non-Mac platforms, since com.apple.eawt.ApplicationAdapter won't be
there. Instead, I've tried this:

(define-simple-class <my-application-adapter> ((<java.lang.Class>:forName
"com.apple.eawt.ApplicationAdapter"))
...)

However, I get an "invalid super type" compile-time error.

I would like to be able to implement com.apple.eawt.ApplicationAdapter at
runtime. For now I'm commenting out the line where the file containing this
code is required when I compile, but this is not ideal.

Anyone have any suggestions as to how to do this?

thanks,
Alex
