[PyQt] Extracting QMap<int, QVariant> from a QDataStream

[Paul Giannaros]

I'm trying to receive drops on my widget from a QListWidget. As the Qt4 
documentation is fairly bad regarding what data is stored in the QMimeType of 
a QDropEvent, I've been looking at the source. The data is packed into a 
QDataStream with the following:

int r, c;
QMap<int, QVariant> v;
stream >> r >> c >> v;

Where r and c are row and column respectively (extracting with a readUInt32 
from my drop event confirms that). I think the QMap maps column to text.
How do I extract that QMap from the data stream? I imagine it's not going to 
be straightforward as QMap isn't present in the bindings.
