-    \title Item Model Example
-    \ingroup qtdatavisualization_examples
-    \brief Using an item model as data source for Q3DBars.
-
-    The item model example shows how to make a simple 3D bar graph using Q3DBars and how to modify
-    the data being drawn at run-time. The example shows how to:
-
-    \list
-        \li Create an application with Q3DBars and widgets
-        \li Use QItemModelBarDataProxy to set data to the graph
-        \li Use a table widget to modify the data in the graph
-    \endlist
-
-    For instructions about how to interact with the graph, see \l{Qt Data Visualization Interacting with Data}{this page}.
-
-    \image itemmodel-example-2.png
-
-    \include examples-run.qdocinc
-
-    \section1 Creating the Application
-
-    First, in main.cpp, we create a QApplication, instantiate Q3DBars and a window container for it:
-
-    \snippet itemmodel/main.cpp 0
-
-    The call to QWidget::createWindowContainer is required, as all data visualization graph classes
-    (Q3DBars, Q3DScatter, and Q3DSurface) inherit QWindow. Any class inheriting QWindow cannot be used
-    as a widget any other way.
-
-    Then we'll create a layout and add the graph and the table widget into it:
-
-    \snippet itemmodel/main.cpp 1
-
-    The table widget is going to be used to display the numerical data being inserted into the
-    graph, and to modify it (See \l {Adding data to the graph} and \l {Interacting with the data}).
-
-    We need to instantiate QItemModelBarDataProxy and a QBar3DSeries for it, and give the series
-    to the graph:
-
-    \snippet itemmodel/main.cpp 2
-
-    Here we tell the proxy to directly map the model's rows and columns into the proxy's rows and
-    columns instead of defining row and column roles to map for them. Then we give the model from
-    the table widget to the proxy. We also create a series instance and set the proxy to it.
-    We customize the series visuals a bit by changing the object mesh to pyramids, and finally
-    add the series to the graph.
-
-    Next, let's create another class to handle the data addition and other interaction with the
-    graph. Let's call it \c GraphDataGenerator (See \l {Setting up the graph} and
-    \l {Adding data to the graph} for details) and connect some signals between QBar3DSeries,
-    \c GraphDataGenerator, and QTableWidget (See \l {Interacting with the data} for a closer look):
-
-    \snippet itemmodel/main.cpp 3
-
-    The application main is done and we can show the graph and start the event loop:
-
-    \snippet itemmodel/main.cpp 4
-
-    \section1 Setting up the Graph
-
-    Let's set up the visual attributes for the graph in the constructor of \c GraphDataGenerator:
-
-    \snippet itemmodel/main.cpp 5
-    \snippet itemmodel/main.cpp 6
-    \snippet itemmodel/main.cpp 7
-
-    First we set bar thickness ratio to 1.0, which means bars will be as wide as they are deep. 1.0
-    is also the default value, so the line is basically unnecessary. It's left there so you could
-    easily try how changing it affects the graph. The second line sets bar spacings to 0.2, which
-    means there will be a gap of 20% of the bar's thickness between the bars in both directions.
-
-    We want to be able to select rows of data for a closer inspection, so we set the selection mode
-    to slice item and row. This means that whenever we select a bar in the graph, the whole row will be
-    displayed separately and the selected bar will be highlighted.
-
-    We don't want to use the default colors, so we set one of the predefined themes as the active theme.
-
-    Next line sets the font to \c Impact. If your system doesn't have it, it will be replaced by
-    the system default.
-
-    And finally, we set the camera position to one of the predefined camera positions.
-    Now the initial graph settings are done.
-
-    \note You do not need to set any of these in case you're happy with the defaults. You can
-    easily try them by commenting out the contents of the constructor.
-
-    \section1 Adding Data to the Graph
-
-    We created the data generator in the application main and gave it the graph and the table
-    widget as parameters:
-
-    \code
-    GraphDataGenerator generator(graph, tableWidget);
-    \endcode
-
-    We added a separate start method to the generator, so that it wouldn't start doing anything
-    until everything else is set up. We then called the method when starting the application:
-
-    \code
-    generator.start();
-    \endcode
-
-    Let's have a look at the contents of the \c start() method:
-
-    \snippet itemmodel/main.cpp 8
-
-    The main thing \c start() does is set up the data model. It also activates a timer for getting
-    the accurate dimensions of the table widget after it's been filled with data. The reason we
-    do this is that the widget doesn't know its final visual domensions until all the data has been
-    inserted to it and it has been shown. The data timer usage is not vital for the
-    application, so we won't take a closer look at it. It's just there to make QTableWidget look better.
-
-    In \c setupModel() we first introduce the row and column labels, and the actual data:
-
-    \snippet itemmodel/main.cpp 9
-
-    Then we set up the axes:
-
-    \snippet itemmodel/main.cpp 10
-
-    Next we will set up the table widget:
-
-    \snippet itemmodel/main.cpp 11
-
-    After that all that's left is adding the data to the table widget:
-
-    \snippet itemmodel/main.cpp 12
-
-    Now we have a bar graph and a table widget, both displaying the same data.
-
-    You're probably wondering how the data can be displayed in the graph, as the only thing we did
-    was add it to the table widget? That's because of what we did earlier, in the application main:
-
-    \snippet itemmodel/main.cpp 2
-
-    We created QItemModelBarDataProxy instance, and gave the proxy the model of the table widget
-    we just created. The proxy maps the rows and the columns in the model of the table widget into
-    rows and columns for itself directly, as we set the QItemModelBarDataProxy::useModelCategories
-    property to true, and the graph gets the data to be displayed via the series that owns the proxy.
-
-    \section1 Interacting with the Data
-
-    We made a couple of signal connections in the application main earlier:
-
-    \snippet itemmodel/main.cpp 3
-
-    Now we'll find out what these were for.
-
-    The first one connects a signal from Q3DBars to the \c GraphDataGenerator. Signal
-    QBar3DSeries::selectedBarChanged() is emitted when a bar is selected from the series. We connect
-    that to a method in the data generator that selects the same data item in the table widget:
-
-    \snippet itemmodel/main.cpp 13
-
-    The second connection does the opposite; it connects a signal from the table widget to a
-    method in the data generator. The method then selects the corresponding bar in the series:
-
-    \snippet itemmodel/main.cpp 14
-
-    You can even select an item in the widget and change the value of it, and the new value is
-    updated to the graph. This is handled again by the proxy with mapping between the data
-    in the table widget and itself.
