<h2>Detailed Description</h2>
<p>The QNetworkConfigurationManager class manages the network configurations provided by the system.</p>
<p>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.</p>
<p>A <a href="qnetworkconfiguration.html">QNetworkConfiguration</a> 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 <a href="qnetworkconfigurationmanager.html#allConfigurations">allConfigurations</a>(). If a new configuration is added or an existing one is removed or changed the <a href="qnetworkconfigurationmanager.html#configurationAdded">configurationAdded</a>(), <a href="qnetworkconfigurationmanager.html#configurationRemoved">configurationRemoved</a>() and <a href="qnetworkconfigurationmanager.html#configurationChanged">configurationChanged</a>() signals are emitted respectively.</p>
<p>The <a href="qnetworkconfigurationmanager.html#defaultConfiguration">defaultConfiguration</a>() can be used when intending to immediately create a new network session without caring about the particular configuration. It returns a <a href="qnetworkconfiguration.html#StateFlag-enum">QNetworkConfiguration::Discovered</a> configuration. If there are not any discovered ones an invalid configuration is returned.</p>
<p>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 <a href="qnetworkconfigurationmanager.html#updateConfigurations">QNetworkConfigurationManager::updateConfigurations</a>(). The completion of the update process is indicated by emitting the <a href="qnetworkconfigurationmanager.html#updateCompleted">updateCompleted</a>() signal. The update process ensures that every existing <a href="qnetworkconfiguration.html">QNetworkConfiguration</a> instance is updated. There is no need to ask for a renewed configuration list via <a href="qnetworkconfigurationmanager.html#allConfigurations">allConfigurations</a>().</p>

<p>Returns the list of configurations which comply with the given <i>filter</i>.</p>
<p>By default this function returns all (defined and undefined) configurations.</p>
<p>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.</p>
<p>If <i>filter</i> is set to zero this function returns all possible configurations.</p>
<p>Note that this function returns the states for all configurations as they are known at the time of this function call. If for instance 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 <a href="qnetworkconfigurationmanager.html#updateConfigurations">updateConfigurations</a>() should be used to update each configuration's state. Note that such an update may require some time. It's completion is signalled by <a href="qnetworkconfigurationmanager.html#updateCompleted">updateCompleted</a>(). In the absence of a configuration update this function returns the best estimate at the time of the call. Therefore, if WLAN configurations are of interest, it is recommended that <a href="qnetworkconfigurationmanager.html#updateConfigurations">updateConfigurations</a>() is called once after <a href="qnetworkconfigurationmanager.html">QNetworkConfigurationManager</a> instantiation (WLAN scans are too time consuming to perform in constructor). After this the data is kept automatically up-to-date as the system reports any changes.</p>

<p>Initiates an update of all configurations. This may be used to initiate WLAN scans or other time consuming updates which may be required to obtain the correct state for configurations.</p>
<p>This call is asynchronous. On completion of this update the <a href="qnetworkconfigurationmanager.html#updateCompleted">updateCompleted</a>() signal is emitted. If new configurations are discovered or old ones were removed or changed the update process may trigger the emission of one or multiple <a href="qnetworkconfigurationmanager.html#configurationAdded">configurationAdded</a>(), <a href="qnetworkconfigurationmanager.html#configurationRemoved">configurationRemoved</a>() and <a href="qnetworkconfigurationmanager.html#configurationChanged">configurationChanged</a>() signals.</p>
<p>If a configuration state changes as a result of this update all existing <a href="qnetworkconfiguration.html">QNetworkConfiguration</a> instances are updated automatically.</p>
