It stores an OR combination of Capability values. The Capabilities type is a typedef for QFlags. If this flag is set the platform requires that a network session is created before network operations can be performed. QNetworkConfigurationManager::NetworkSessionRequired If this flag is set QNetworkSession can provide statistics about transmitted and received data. QNetworkConfigurationManager::DataStatistics The application does not have any control over this process and has to reconnect its active sockets. The system disconnects an existing access point and reconnects via a more suitable one. QNetworkConfigurationManager::ForcedRoaming Applications can initiate roaming (in case the current link is not suitable) and are consulted if the system has identified a more suitable access point. The system gives applications control over the systems roaming behavior. QNetworkConfigurationManager::ApplicationLevelRoaming In general mobile platforms have such support whereas most desktop platform lack this capability. If the platform session support is missing this API can only ensure the above behavior for network sessions within the same process. If this flag is set the underlying platform ensures that a network interface is not shut down until the last network session has been closed(). QNetworkConfigurationManager::SystemSessionSupport This option is platform specific and may not always be available. This may be useful when two interfaces can reach overlapping IP ranges or an application has specific needs in regards to target networks. Any packet that passes through the socket goes to the specified network interface and thus disregards standard routing table entries. Network sessions and their sockets can be bound to a particular network interface.
QNetworkConfigurationManager::DirectConnectionRouting On some platforms this feature may require elevated user permissions. If this flag is not set QNetworkSession can only monitor but not influence the state of access points. Network sessions and their underlying access points can be started and stopped. QNetworkConfigurationManager::CanStartAndStopInterfaces There is no need to ask for a renewed configuration list via allConfigurations().

The update process ensures that every existing QNetworkConfiguration instance is updated. The completion of the update process is indicated by emitting the updateCompleted() signal. Unless the platform performs internal updates it may be required to manually trigger configuration updates via QNetworkConfigurationManager::updateConfigurations(). Some configuration updates may require some time to perform updates. If there are not any discovered ones an invalid configuration is returned. It returns a QNetworkConfiguration::Discovered configuration. The defaultConfiguration() can be used when intending to immediately create a new network session without caring about the particular configuration.
If a new configuration is added or an existing one is removed or changed the configurationAdded(), configurationRemoved() and configurationChanged() signals are emitted respectively. Applications can access and filter this list via allConfigurations(). QNetworkConfigurationManager maintains and updates the global list of QNetworkConfigurations. 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.Ī QNetworkConfiguration abstracts a set of configuration options describing how a network interface has to be configured to connect to a particular target network.
