After a more deeper investigation, I got it working. As I'm hacking this into
Qt, I was trying to minimize things to patch in their code, so I was using
PasteboardCreate(NULL) in order to obtain the exact same global pasteboard
they were using in their code (based on what's described at
http://developer.apple.com/documentation/Carbon/Reference/Pasteboard_Reference/Reference/reference.html#/ /apple_ref/c/func/PasteboardCreate
). However, it seems I was in fact not obtaining the same pasteboard, but a
different one? (at least it's the only explanation I have at the moment).
So I tried to export the exact PasteboardRef Qt is using internally, replaced
my PasteboardCreate() calls by this ref, and now it works perfectly!

Excellent! I'm glad you got things working. Yes, PasteboardCreate( NULL ) is equivalent to PasteboardCreate( kPasteboardUniqueName ). This will give you a completely new, unique pasteboard. Probably not what you want. In general, you can get the drag pasteboard via GetDragPasteboard in Drag.h.



Btw, is is possible to reuse Finder's own copy dialog box in order to display
progress for the files I'm copying (through a particular AppleEvent?),
or am I forced to manually reimplement the same thing in my application?

I believe there are AppleEvents for this. Try looking at Finder with Script Editor to see what AppleEvent services it offers.
