Detailed Description

Browses the service types being published on a domain.

This class is mostly useful for generic utilities for browsing all the published service types on a local network. Applications that wish to find out about available services of a particular type (such as web servers) should use ServiceBrowser.

ServiceTypeBrowser provides a list of all the service types published by at least one service on a given domain.

Constructor & Destructor Documentation

KDNSSD::ServiceTypeBrowser::ServiceTypeBrowser ( const QString domain = QString(),
QObject parent = nullptr 
)
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
domaina browsing domain to search
parentthe parent object (see QObject documentation)

startBrowse() and ServiceBrowser::isAvailable()

Member Function Documentation

void KDNSSD::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.

See also
serviceTypeAdded() and serviceTypeRemoved()
bool KDNSSD::ServiceTypeBrowser::isRunning ( ) const
inline

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

Deprecated:
since 4.0, just call startBrowse() again.

Definition at line 87 of file servicetypebrowser.h.

void KDNSSD::ServiceTypeBrowser::serviceTypeAdded ( const QString type)
signal

A new type of service has been found.

Parameters
typethe service type
See also
serviceTypeAdded() and finished()
void KDNSSD::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
typethe service type
See also
serviceTypeAdded() and finished()
QStringList KDNSSD::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 147 of file avahi-servicetypebrowser.cpp.

void KDNSSD::ServiceTypeBrowser::startBrowse ( )

Starts browsing.

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

Browsing stops when the ServiceTypeBrowser object is destroyed.

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

serviceTypeAdded(), serviceTypeRemoved() and finished()
