Ok, giving some context: the mediabrowser applet we use in PMC takes
advantage of an AbstractItemView written from scratch (aka not inheriting
from QAbstractItemView).
This means that the QAbstractItemModel passed is handled internally. If the
set model makes use of KDirModel::FileItemRole additional capabilities are
enabled:
this means that not only the name and the icon is drawn but now, through the
given KFileItem, the view has access to the URL of the file and can, for
example, retrieve previews.
Unfortunately I cannot make use of KDirOperator as long as PMC has this
particular structure. My concern now is: is there a way to get the file url
for the particular nepomuk search result?
I might go for Nepomuk::Resource::property(Vocabulary::NIE::url()) i don't
know how to build the resource from the given QModelIndex.

Hints appreciated :p

Thank you.

P.S.: forgot to mention that I'm using Nepomuk::Query::toSearchUrl too,
passing it to the KDirLister->openUrl() method.
