| 27 | * \brief Model for list of Zeroconf services. |
| 28 | * |
| 29 | * This class provides a Qt Model for ServiceBrowser to allow easy |
| 30 | * integration of service discovery into a GUI. For example, to |
| 31 | * show the HTTP servers published on the local network, you can do: |
| 32 | * \code |
| 33 | * KDNSSD::ServiceModel *serviceModel = new ServiceModel( |
| 34 | * new KDNSSD::ServiceBrowser("_http._tcp") |
| 35 | * ); |
| 36 | * QComboBox *serviceCombo = new QComboBox(); |
| 37 | * serviceCombo->setModel(serviceModel); |
| 38 | * \endcode |
| 39 | * |
| 40 | * After the user makes a selection, the application typically needs |
| 41 | * to get a pointer to the selected service in order to get the host |
| 42 | * name and port. A RemoteService::Ptr can be obtained from |
| 43 | * a QModelIndex using: |
| 44 | * \code |
| 45 | * void onSelected(const QModelIndex &selection) { |
| 46 | * KDNSSD::RemoteService::Ptr service = |
| 47 | * selection.data(KDNSSD::ServiceModel::ServicePtrRole) |
| 48 | * .value<KDNSSD::RemoteService::Ptr>(); |
| 49 | * } |
| 50 | * \endcode |
| 51 | * |
