It's been a while since I looked at this sort of thing, and the example I
hoped would help me remember doesn't actually do anything with URLs...

You need to set the URL of the MIME data you create when you start a drag
operation:

I seem to remember that you have to supply URLs for certain things to work
on certain systems, and this may mean that you have to save data to a
temporary file, then set the URL of that file, when filling in the MIME data.

Here is one way to do it that doesn't use a temporary file:

The Drop Site example in Qt is useful for looking at the MIME types of data
dragged from other applications. It would be useful if someone ported that
to PyQt.
