I would try to change the class from <Is a QMultimap> to <Has a
QMultimap>. If I remember correctly from a short look yesterday, nowhere
in the code are the QMultimap methods of AppointmentIntervalList used,
beside within the implementation of AppointmentIntervalList itself.
So maybe using the follwing construct will work:
class AppointmentIntervalBase
{
// all your existing methods go here
private:
QMultiMap<QDate, AppointmentInterval> m_data;
};
