+    \example feature
+    \title KNX Tunneling Features Example
+    \ingroup qtknx-examples
+
+    \brief A KNX client for handling KNXnet/IP tunneling features.
+
+    \image features.png "KNX tunneling features example"
+
+    The \e{KNX Tunneling Features} user interface contains various
+    Qt Widgets, most prominently a \l QTreeWidget to display detailed
+    information about sent and received KNX tunneling feature messages.
+
+    To get started, users select one of the network interfaces on their
+    machine in the \uicontrol {Interface} field. Once that is done, the
+    application automatically performs a continuous search for available
+    KNXnet/IP devices and displays the results in the \uicontrol {Device}
+    field.
+
+    To connect to a KKXnet/IP device, either the one preselected in the
+    \uicontrol {Device} can be used or a different one must be chosen from
+    the list of discovered devices.
+
+    The application also supports KNXnet/IP secure devices, but to be able to
+    connect to such a device, a KNX ETS keyring file needs to be imported via
+    the \uicontrol {File} menu.
+
+    Once a connection is successfully established, the user has the possibility
+    to send tunneling feature get or set commands and to monitor incoming tunnel
+    feature info messages.
+
+    The application consists of two classes:
+
+    \list
+        \li \c MainWindow is a \l QMainWindow that renders the general layout
+            of the application.
+        \li \c DeviceItem is a \l QStandardItem that is used to display
+            and store information about discovered KNXnet/IP devices.
+    \endlist
+
+    \section1 Main Window Class Definition and Implementation
+
+    \quotefromfile feature/mainwindow.h
+    \skipto class MainWindow :
+    \printuntil /^\}/
+
+    The \c MainWindow class uses a \l QKnxNetIpServerDiscoveryAgent instance
+    that allows discovering KNXnet/IP servers by sending continuous search
+    requests to the network that the client is connected to. It also saves an
+    instance of the \l QKnxNetIpTunnel used to establish the connection to the
+    KNX network and a list of imported KNX \l QKnxNetIpSecureConfiguration
+    secure configurations.
+
+    There are signal handlers installed for every signal emitted by the
+    \l QKnxNetIpTunnel. Here is an example of the setup capturing the
+    signals emitted when an event occurs targeting the KNXnet/IP connection.
+    In this specific example, we will also see how to set up the KNXnet/IP
+    tunnel and connect to the KNXnet/IP device:
+
+    \quotefromfile feature/mainwindow.cpp
+    \skipto MainWindow::MainWindow
+    \printuntil {
+    \dots
+    \skipto QKnxNetIpTunnel::connected
+    \printuntil MainWindow::onErrorOccurred);
+    \dots
+    \skipto /^\}/
+    \printuntil /^\}/
+    \skipto void MainWindow::on_connection_clicked
+    \printuntil /^\}/
+
+    The \c QKnxNetIpServerDiscoveryAgent is initialized and started after the
+    user interface has been set up and the necessary tunnel connections have
+    been made. Here is the code snippet doing it:
+
+    \quotefromfile feature/mainwindow.cpp
+    \skipto MainWindow::MainWindow
+    \printuntil {
+    \dots
+    \skipto m_discoveryAgent.setTimeout
+    \printuntil /^\}/
+
+    There is a signal handler installed for the device discovered signal
+    emitted by the discovery agent.
+    When the signal \l QKnxNetIpServerDiscoveryAgent::deviceDiscovered is
+    triggered, the function \c MainWindow::onDeviceDiscovered() is called.
+    It adds a new device item to the \uicontrol {Device} if it is not already
+    there.
+
+    \quotefromfile device/mainwindow.cpp
+    \skipto void MainWindow::onDeviceDiscovered
+    \printuntil /^\}/
+
+    At this point, users can select one of the available devices to establish
+    a connection, create and send the different types of frames or monitor the
+    KNX tunneling feature info messages.
+    The \c MainWindow::on_devices_currentIndexChanged method saves the selected
+    KNXnet/IP device in the the \c MainWindow instance.
+
+    In this last example, after the user has triggered the \uicontrol {Read}
+    button and a valid tunneling feature response was received, the function
+    \c MainWindow::setText() is called and the frame content gets extracted
+    and visually processed:
+
+    \quotefromfile feature/mainwindow.cpp
+    \skipto MainWindow::setText
+    \printuntil /^\}/
+
+    \section1 The Main Function
+
+    The KNX tunneling feature example \c main() function does not have any
+    special handling. It looks like the main function for any Qt application:
+
+    \quotefromfile feature/main.cpp
+    \skipto #include
+    \printuntil /^\}/
