-    \example network/bearercloud
-    \title Bearer Cloud Example
-
-    The Bearer Cloud example shows how to use the Bearer Management API to monitor the
-    connectivity state of the local device.
-
-    \image bearercloud-example.png Screenshot of the Bearer Cloud example
-
-    Bearer Management provides the QNetworkConfigurationManager class which can be used to monitor
-    changes in the available \l {QNetworkConfiguration}{network configurations} and the
-    QNetworkSession class which is used to \l {QNetworkSession::open()}{open} and
-    \l {QNetworkSession::close()}{close} a session bringing a network interface up or down if
-    necessary.
-
-    This example displays all known \l {QNetworkConfiguration}{network configurations} in a cloud
-    orbiting the local device.  There are four orbits representing the four possible
-    \l {QNetworkConfiguration::StateFlags}{states} that the network configuration can be in.
-    The closer the orbit the more useful the network configuration is in its current state.
-    The inner orbit is populated with network configurations that are in the
-    \l {QNetworkConfiguration::Active}{Active} state.  The second orbit is populated with network
-    configurations that are in the \l {QNetworkConfiguration::Discovered}{Discovered} state.  The
-    third orbit is populated with network configurations that are in the
-    \l {QNetworkConfiguration::Defined}{Defined} state.  Finally the outer orbit is populated by
-    configurations that are in the \l {QNetworkConfiguration::Undefined}{Undefined} state.
-
-    Hovering the mouse over a network configuration will display information about the network
-    configuration in a tool tip.
-
-    Double clicking on an Active or Discovered network configuration will
-    \l {QNetworkSession::close()}{close} or \l {QNetworkSession::open()}{open} a network session,
-    respectively.
-
-    Lastly you can reorganize the cloud without changing the state of the network configurations by
-    dragging them around.
-
-    This example consists of two main classes, the BearerCloud and Cloud classes.  The Cloud class
-    represents a single network session and associated network configuration.  The BearerCloud
-    class implements a Graphics View scene and manages the life-cycle of Cloud
-    objects in response to notification signals from QNetworkConfigurationManager.
-
-    \section1 Setting the Scene
-
-    When constructing the scene we first calculate some random offsets using \l
-    QRandomGenerator. We will use these offsets to scatter the initial position
-    of new Cloud objects.
-
-    Next we place a text item in the center of the scene to represent the local device and
-    surround it with four concentric circles to help visualize the orbits.
-
-    Finally we connect up the network configuration notification signals and queue the initial
-    population of the scene during the next iteration of the event loop.
-
-    \snippet examples/network/bearercloud/bearercloud.cpp 0
-
-    Populating the scene with the initial list of known network configuration is easy.  Iterate
-    over the list returned by QNetworkConfigurationManager::allConfigurations(), calling our
-    configurationAdded() slot on each one.
-
-    We finishing off by calling cloudMoved() to ensure that animations are started.
-
-    \snippet examples/network/bearercloud/bearercloud.cpp 1
-
-    The configurationAdded() slot gets called when a new network configuration is added to the
-    system.
-
-    It stores the \l {QNetworkConfiguration::identifier()}{identifier} of the network
-    configuration in the \e {configStates} map, which is used to keep a count of the number of
-    network configurations in each state.  This in turn is used to calculate the initial position
-    of new Cloud objects.
-
-    Next we create a new Cloud object for this network configuration.  Set its initial position
-    and store it in the \e {configurations} hash.
-
-    The last step is to add it to the scene by calling QGraphicsScene::addItem().
-
-    \snippet examples/network/bearercloud/bearercloud.cpp 2
-
-    The configurationRemoved() slot gets called when a network configuration is removed from the
-    system.
-
-    First we remove all references to the network configuration from the \e {configStates} and
-    \e {configurations} member variables.
-
-    Next we initiate animation by setting a final scale value on the Cloud object associated with
-    the removed network configuration.
-
-    Finally we flag the Cloud object to delete itself after it has finished animating.
-
-    \snippet examples/network/bearercloud/bearercloud.cpp 3
-
-    The Cloud object will take care of most of the work required when a network configuration
-    changes.  All we do in the configurationChanged() slot is update the \e {configStates} member
-    variable.
-
-    \snippet examples/network/bearercloud/bearercloud.cpp 4
-
-
-    \section1 Responding to Changes
-
-    Each network session and associated network configuration known to the system is represented in
-    the scene as a Cloud object.
-
-    In the Cloud constructor we first initialize member variables.  Then we create a new
-    QNetworkSession object bound to the network configuration.  Next we connect the QNetworkSession
-    signals which we use to monitor it for state changes.
-
-    Next we set some QGraphicsItem properties.  The QGraphicsItem::ItemIsMovable flag enables mouse
-    interaction with the Cloud object.
-
-    The Cloud object consists of an icon and a text caption, these are constructed here.  We will
-    assign values to them later, as these will change as the sessions state changes.
-
-    Next we set the initial animation state and call our newConfigurationActivated() slot to finish
-    setting up the Cloud object based on the state of network session.
-
-    \snippet examples/network/bearercloud/cloud.cpp 0
-
-    The newConfigurationActivated() slot is called when a session has successfully roamed from one
-    access point to another.
-
-    The first thing we do is set the icon, inserting it into a shared SVG renderer cache if it is
-    not already available.  Next we set the text caption to the name of the network configuration.
-
-    We then set the position of the icon and text caption so that they are centered horizontally.
-
-    Finally we call our stateChanged() slot.
-
-    \snippet examples/network/bearercloud/cloud.cpp 1
-
-    The stateChanged() slot is called when the session state changes.
-
-    In this slot we set lower the opacity of Cloud objects with network sessions that cannot be
-    \l {QNetworkSession::open()}{opened}, and set a detailed tool tip describing the sessions
-    state.
-
-    \snippet examples/network/bearercloud/cloud.cpp 2
-
-    In our reimplementation of the QGraphicsItem::mouseDoubleClickEvent() function we call
-    QNetworkSession::open() or QNetworkSession::close() to open or close the session in response
-    to a double left click.
-
-    \snippet examples/network/bearercloud/cloud.cpp 3
-
-    As we support the user dragging Cloud objects around we need to restart animations when the
-    position of the Cloud object changes.  This is accomplished by reimplementing the
-    QGraphicsItem::itemChanged() function and calling the cloudMoved() function of the BearerCloud
-    object.
-
-    \snippet examples/network/bearercloud/cloud.cpp 4
-
-    The remainder of the code for the Cloud object implements the animations.  The
-    calculateForces() function calculates the new position of the Cloud object based on the
-    position of all the other Cloud objects in the scene.  The new position is set when the
-    advance() function is called to update the Cloud object for the current animation frame.
