/**
* @class ServiceModel servicemodel.h DNSSD/ServiceModel
* @short Model for list of Zeroconf services
*
* This class provides a Qt Model for ServiceBrowser to allow easy
* integration of service discovery into a GUI. For example, to
* show the HTTP servers published on the local network, you can do:
* @code
* DNSSD::ServiceModel *serviceModel = new ServiceModel(
* new DNSSD::ServiceBrowser("_http._tcp")
* );
* QComboBox *serviceCombo = new QComboBox();
* serviceCombo->setModel(serviceModel);
* @endcode
*
* After the user makes a selection, the application typically needs
* to get a pointer to the selected service in order to get the host
* name and port. A RemoteService::Ptr can be obtained from
* a QModelIndex using:
* @code
* void onSelected(const QModelIndex &selection) {
* DNSSD::RemoteService::Ptr service =
* selection.data(DNSSD::ServiceModel::ServicePtrRole)
* .value<DNSSD::RemoteService::Ptr>();
* }
* @endcode
*
* @since 4.1
