To connect a model to QML, one is supposed to provide a QHash<int, QByteArray> MapLocationModel::roleNames() function that returns a role -> attribute-name hash. That was realized by filling the hash in the constructor, storing it as a member variable, using static strings that were declared in the class-definition and defined in the translation unit. Adding a new role was a pain and the whole thing was totally pointless as the attribute names were used nowhere else and the roleNames() function is called only once. Simply do, what we do everywhere else: initialize the hash in the roleNames() function and use normal string literals. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
