Please don't, as I've found a way to make it work, e.g.:

class Preview(QLabel):
    def __init__(self, parent = None):
        QLabel.__init__(self, parent)
        self.preview = QFilePreview()
        self.preview.previewUrl = self.previewUrl

BTW, did you notice the decode problem in the dirview example. 
Dropping an item somewhere always decodes as an empty list:

            # currently used:
            lst = QStringList()
            QUriDrag.decodeLocalFiles(e, lst)

            # similar as in dirview.cpp:
            lst = []
            QUriDrag.decode(e, lst)

I already tried to keep references on the dragged items, but that 
doesn't change the picture.

Could you take another look into this? In return, I can offer an 
adapted qdir example, which also uses dirview.

Have a nice weekend,
