ServiceTypeBrowser (const QString &domain=QString(), QObject *parent=nullptr) | |
Create a ServiceTypeBrowser for a domain. | |
bool | isRunning () const |
This method is unnecessary, since it is safe to call startBrowse() multiple times. | |
QStringList | serviceTypes () const |
All the service types currently being published. | |
void | startBrowse () |
Starts browsing. | |
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.

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

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.
