[Interest] QEvent::FileOpen : opening single vs. multiple documents

Judging from the behaviour of native Mac applications like Preview.app there must be a distinction in the LaunchServices messages being sent when the user requests the opening of a single document vs. a collection of documents. Preview.app for instance will open a new window for each request, containing all the documents of that request in individual tabs.

Qt doesn't seem to allow that but sends QFileOpenEvents for each individual document. In my experience one can typically do a QCoreApplication::processEvents() immediately after installing the event filter to catch all documents "with which" the application was launched. Has anyone found a simple way to regroup subsequent QFileOpenEvents?
