The QNetworkConfigurationManager class manages the network configurations provided by the system.
QNetworkConfigurationManager provides access to the network configurations known to the system and enables applications to detect the system capabilities (with regards to network sessions) at runtime.
A QNetworkConfiguration abstracts a set of configuration options describing how a network interface has to be configured to connect to a particular target network. QNetworkConfigurationManager maintains and updates the global list of QNetworkConfigurations. Applications can access and filter this list via allConfigurations(). If a new configuration is added or an existing one is removed or changed the configurationAdded(), configurationRemoved() and configurationChanged() signals are emitted respectively.
The defaultConfiguration() can be used when intending to immediately create a new network session without caring about the particular configuration. It returns a QNetworkConfiguration::Discovered configuration. If there are not any discovered ones an invalid configuration is returned.
Some configuration updates may require some time to perform updates. A WLAN scan is such an example. Unless the platform performs internal updates it may be required to manually trigger configuration updates via QNetworkConfigurationManager::updateConfigurations(). The completion of the update process is indicated by emitting the updateCompleted() signal. The update process ensures that every existing QNetworkConfiguration instance is updated. There is no need to ask for a renewed configuration list via allConfigurations().

Returns the list of configurations which comply with the given flags. By default this method returns a list of all the defined and undefined configurations. If flags is empty this method returns all possible configurations.
A wireless network with a particular SSID may only be accessible in a certain area despite the fact that the system has a valid configuration for it. Therefore the filter flag may be used to limit the list to discovered and possibly connected configurations only.
This method returns the states for all configurations as they are known at the time of this method call. If a configuration of type WLAN is defined, the system may have to perform a WLAN scan in order to determine whether it is actually available. To obtain the most accurate state updateConfigurations() should be used to update each configuration's state. This operation may be slow. The completion is signalled by updateCompleted().
In the absence of a configuration update this method returns the best estimate at the time of the call. Therefore, if WLAN configurations are of interest, it is recommended that updateConfigurations() is called once after QNetworkConfigurationManager instantiation (WLAN scans are too time consuming to perform in constructor). After this, the data is kept automatically up todate as the system reports any changes.
