Detailed Description

ServiceModel servicemodel.h DNSSD/ServiceModel 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>();
 }

__init__	(	self,
		DNSSD.ServiceBrowser	browser,
		QObject	parent=0
	)

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.
