hi all,
when i run the drop site example and drag an file into the application.it will not show the mime data about the file type. the results are always like those:

application/x-qt-windows-mime;value="Shell IDList Array"
application/x-qt-windows-mime;value="DragImageBits"
application/x-qt-windows-mime;value="DragContext"
application/x-qt-windows-mime;value="InShellDragLoop"
text/uri-list
application/x-qt-windows-mime;value="FileName"
application/x-qt-windows-mime;value="FileNameW"

i think if i drag a *.txt file, there will be an item named text/plain.
why?
