with @jsinterop you can (untested of course)
@JsType(isNative = true)
public class JavaScriptFile {
public String filename;
public String anotherMember;
}
then __if__ you can cast JavaScriptObject to the @jsinterop type you can
acces its fields directly.
with jsni you can do that (also untested)
public native String getFile(JavaScriptObject jsfile) /*-{
return jsfile.filename;
}-*;
Afaik JSNI is not the proffered way of doing things in the GWT world.
Hope that helps
