-    \title Simple Widget Mapper Example
-    \ingroup examples-itemviews
-    \brief The Simple Widget Mapper example shows how to use a widget mapper to display
-    data from a model in a collection of widgets.
-
-    \image simplewidgetmapper-example.png
-
-    The QDataWidgetMapper class allows information obtained from a
-    \l{Model Classes}{model} to be viewed and edited in a collection of
-    widgets instead of in an \l{View Classes}{item view}.
-    Any model derived from QAbstractItemModel can be used as the source of
-    data and almost any input widget can be used to display it.
-
-    The example itself is very simple: we create \c Window, a QWidget subclass
-    that we use to hold the widgets used to present the data, and show it. The
-    \c Window class will provide buttons that the user can click to show
-    different records from the model.
-
-    \section1 Window Class Definition
-
-    The class provides a constructor, a slot to keep the buttons up to date,
-    and a private function to set up the model:
-
-    \snippet itemviews/simplewidgetmapper/window.h Window definition
-
-    In addition to the QDataWidgetMapper object and the controls used to make
-    up the user interface, we use a QStandardItemModel to hold our data.
-    We could use a custom model, but this standard implementation is sufficient
-    for our purposes.
-
-    \section1 Window Class Implementation
-
-    The constructor of the \c Window class can be explained in three parts.
-    In the first part, we set up the widgets used for the user interface:
-
-    \snippet itemviews/simplewidgetmapper/window.cpp Set up widgets
-
-    We also set up the buddy relationships between various labels and the
-    corresponding input widgets.
-
-    Next, we set up the widget mapper, relating each input widget to a column
-    in the model specified by the call to \l{QDataWidgetMapper::}{setModel()}:
-
-    \snippet itemviews/simplewidgetmapper/window.cpp Set up the mapper
-
-    We also connect the mapper to the \uicontrol{Next} and \uicontrol{Previous} buttons
-    via its \l{QDataWidgetMapper::}{toNext()} and
-    \l{QDataWidgetMapper::}{toPrevious()} slots. The mapper's
-    \l{QDataWidgetMapper::}{currentIndexChanged()} signal is connected to the
-    \c{updateButtons()} slot in the window which we'll show later.
-
-    In the final part of the constructor, we set up the layout, placing each
-    of the widgets in a grid (we could also use a QFormLayout for this):
-
-    \snippet itemviews/simplewidgetmapper/window.cpp Set up the layout
-
-    Lastly, we set the window title and initialize the mapper by setting it to
-    refer to the first row in the model.
-
-    The model is initialized in the window's \c{setupModel()} function. Here,
-    we create a standard model with 5 rows and 3 columns, and we insert some
-    sample names, addresses and ages into each row:
-
-    \snippet itemviews/simplewidgetmapper/window.cpp Set up the model
-
-    As a result, each row can be treated like a record in a database, and the
-    widget mapper will read the data from each row, using the column numbers
-    specified earlier to access the correct data for each widget. This is
-    shown in the following diagram:
-
-    \image widgetmapper-simple-mapping.png
-
-    Since the user can navigate using the buttons in the user interface, the
-    example is fully-functional at this point, but to make it a bit more
-    user-friendly, we implement the \c{updateButtons()} slot to show when the
-    user is viewing the first or last records:
-
-    \snippet itemviews/simplewidgetmapper/window.cpp Slot for updating the buttons
-
-    If the mapper is referring to the first row in the model, the \uicontrol{Previous}
-    button is disabled. Similarly, the \uicontrol{Next} button is disabled if the
-    mapper reaches the last row in the model.
-
-    \section1 More Complex Mappings
-
-    The QDataWidgetMapper class makes it easy to relate information from a
-    model to widgets in a user interface. However, it is sometimes necessary
-    to use input widgets which offer choices to the user, such as QComboBox,
-    in conjunction with a widget mapper.
-
-    In these situations, although the mapping to input widgets remains simple,
-    more work needs to be done to expose additional data to the widget mapper.
-    This is covered by the \l{Combo Widget Mapper Example}{Combo Widget Mapper}
-    and \l{SQL Widget Mapper Example}{SQL Widget Mapper}
-    examples.
