-    \example accontrol
-    \ingroup qtopcua-examples
-    \title Using QOpcUaClient in a basic UI application
-
-    \section1 Prerequisites
-    This example expects a server with a certain node structure. The
-    testserver from \l tests/freeopcua-testserver/ can be used. The server
-    has to be started before the client and if it does not listen on the
-    default opc.tcp://localhost:43344, you will have to provide a command
-    line option "-e" to the client to connect to the right place.
-
-    \section1 Used features of QOpcUaClient
-    This example uses QOpcUaClient to connect to an OPC UA server which has
-    a model of an air conditioner.
-    Subscriptions are used to update progress bars with a server side value,
-    data from a slider is written to the server, data and units are read from
-    the server, methods are called and Event messages are written to a label.
-
-    \section1 Implementation
-
-    \quotefromfile accontrol/accontroltest.cpp
-
-    First, the UI is modelled using the Designer. For convenience, all elements
-    are given speaking names to simplify using them from the C++ code.
-    This also creates a C++ class in which we include member variables and
-    methods for the communication with the OPC UA server.
-
-    In the constructor, we create a QOpcUaClient object using the
-    QOpcUaProvider and connect it to the OPC UA server.
-
-    \skipto m_pProvider
-    \printuntil createClient();
-    \codeline
-
-    \skipto bool
-    \printuntil }
-
-    After a successful connect, three data change subscriptions are requested
-    and the valueChanged signal is connected to different slots.
-    Two of them update the progress bars, the third one enables and disables
-    the buttons used to trigger server side actions.
-
-    \skipto QOpcUaACControlTest
-    \printuntil updateTemperature
-
-    The slider is connected to a slot which writes the value to the server
-
-    \skipto ui.horizontalSlider
-    \printuntil ;
-
-    \quotefromfile accontrol/accontroltest.cpp
-    \skipto QOpcUaACControlTest::writeValue
-    \printuntil }
-
-    Slots are created and connected to the clicked signal of the buttons. They
-    implement the OPC UA function calls to trigger the server side actions.
-
-    \quotefromfile accontrol/accontroltest.cpp
-    \skipto ui.stopButton
-    \printuntil ;
-
-    \codeline
-
-    \quotefromfile accontrol/accontroltest.cpp
-    \skipto QOpcUaACControlTest::start
-    \printuntil }
-
-    \section1 Usage
-    Dragging the slider updates the setpoint value on the server and via the
-    subscription, the progress bar is also updated with the current server
-    value.
-
-    Clicking the Start and Stop buttons changes the status on the server which
-    toggles the activity of the two buttons. A message is written to the label
-    each time a button is clicked.
