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

NSApplicationDelegate has a method which is called when a request to open multiple files is made.
Qt does indeed enumerate the files in this list and issue a separate file open event for each: https://github.com/qt/qtbase/blob/5.10/src/plugins/platforms/cocoa/qcocoaapplicationdelegate.mm#L297
What we should do instead is allow QFileOpenEvent to store a list of files instead of just a single one. Trying to re-group the events after the fact is probably not a good idea.

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?
