Constructor & Destructor Documentation

DNSSD::ServiceTypeBrowser::ServiceTypeBrowser ( const QString &  domain = QString(), QObject *  parent = 0  )

explicit

Create a ServiceTypeBrowser for a domain.

The link-local domain (the LAN subnet for this computer) will be used if no domain is given. DomainBrowser can be used to get a list of browsing domains.

Note that WAN domains may not support service type browsing.

Parameters

domain	a browsing domain to search
parent	the parent object (see QObject documentation)

Member Function Documentation

void DNSSD::ServiceTypeBrowser::finished ( )

signal

Emitted when the list of published service types has settled.

This signal is emitted once after startBrowse() is called when the types of all the services that are currently published have been reported (even if no services are available or the DNS-SD service is not available). It is emitted again when a new batch of service types become available or disappear.

For example, if a new host is connected to network and announces services of several new types, they will be reported by several serviceTypeAdded() signals and the whole batch will be concluded by finished().

This signal can be used by applications that just want to get a list of the currently available service types (similar to a directory listing) and do not care about adding or removing service types that appear or disappear later.

bool DNSSD::ServiceTypeBrowser::isRunning

)

const

Deprecated:

This method is unnecessary, since it is safe to call startBrowse() multiple times.

Definition at line 43 of file dummy-servicetypebrowser.cpp.

void DNSSD::ServiceTypeBrowser::serviceTypeAdded ( const QString &  type )

signal

A new type of service has been found.

Parameters

type	the service type

serviceTypeAdded() and finished()

void DNSSD::ServiceTypeBrowser::serviceTypeRemoved ( const QString &  type )

signal

Emitted when there are no more services of this type.

Warning

This signal is not reliable: it is possible that it will not be emitted even after last service of this type disappeared

Parameters

type	the service type

serviceTypeAdded() and finished()

QStringList DNSSD::ServiceTypeBrowser::serviceTypes

(

)

const

All the service types currently being published.

Returns

a list of service types, in the form _type._tcp or _type._udp

Definition at line 37 of file dummy-servicetypebrowser.cpp.

void DNSSD::ServiceTypeBrowser::startBrowse

(

)

Starts browsing.

Only the first call to this function will have any effect.

Browsing stops when the ServiceBrowser object is destroyed.

Warning

The serviceTypeAdded() signal may be emitted before this function returns.
