I am working on getting the included/imported files watched as well. I have 
worked out this little snippet for getting imports:

    TopDUContext* context = DUChainUtils::standardContextForUrl(url);
    if (context) {
        QVector<DUContext::Import> imports = context-
>importedParentContexts();
        Q_FOREACH(DUContext::Import import, imports) {
            qDebug() << "indexed url for import: " << 
import.indexedContext().indexedTopContext().url().str();
        }
    } else {
        qDebug() << "No context for url";
    }

Is that the right way to do it? Of course, I would need to update the list 
every time the file is parsed, and I think I would need to reparse any new 
files in that list (otherwise, I cannot see how to avoid a race where the file 
is changed after passing but before the import is reported to the watching 
mechanism). 

The above needs to be done recursively: is there a smarter way to go about 
this?
