Detailed Description

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:

DNSSD::ServiceModel *serviceModel = new ServiceModel(
    new DNSSD::ServiceBrowser("_http._tcp")
    );
QComboBox *serviceCombo = new QComboBox();
serviceCombo->setModel(serviceModel);

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:

void onSelected(const QModelIndex &selection) {
    DNSSD::RemoteService::Ptr service =
        selection.data(DNSSD::ServiceModel::ServicePtrRole)
                 .value<DNSSD::RemoteService::Ptr>();
}

Member Enumeration Documentation

enum DNSSD::ServiceModel::AdditionalRoles

The additional data roles provided by this model.

Enumerator
ServicePtrRole	gets a RemoteService::Ptr for the service

Definition at line 73 of file servicemodel.h.

enum DNSSD::ServiceModel::ModelColumns

The default columns for this model.

If service browser is not set to resolve automatically, then the model will only ever have one column (the service name).

Enumerator
ServiceName
Host
Port

Constructor & Destructor Documentation

DNSSD::ServiceModel::ServiceModel ( ServiceBrowser *  browser, QObject *  parent = 0  )

explicit

Creates a model for the given service browser and starts browsing for services.

The model takes ownership of the browser, so there is no need to delete it afterwards.

You should not call ServiceBrowser::startBrowse() on browser before passing it to ServiceModel.
