[Qgis-developer] Getting and setting attribute field names and values for vector layers

[Ole Nielsen]

Thanks for that - I wouldn't have known where to look. But this does the
trick - although for my application I did have a need to explicitly convert
the QString types to unicode.
I looked at methods toAscii() and toLatin1() but neither produced the
python string types I was expecting. Can you comment on that?

Many thanks again
Ole
