-    \example itemviews/pixelator
-    \title Pixelator Example
-    \ingroup examples-itemviews
-    \brief The Pixelator example shows how delegates can be used to customize the way that
-    items are rendered in standard item views.
-
-    \image pixelator-example.png
-
-    By default, QTreeView, QTableView, and QListView use a standard item delegate
-    to display and edit a set of common data types that are sufficient for many
-    applications. However, an application may need to represent items of data in a
-    particular way, or provide support for rendering more specialized data types,
-    and this often requires the use of a custom delegate.
-
-    In this example, we show how to use custom delegates to modify the appearance
-    of standard views. To do this, we implement the following components:
-
-    \list
-    \li A model which represents each pixel in an image as an item of data, where each
-       item contains a value for the brightness of the corresponding pixel.
-    \li A custom delegate that uses the information supplied by the model to represent
-       each pixel as a black circle on a white background, where the radius of the
-       circle corresponds to the darkness of the pixel.
-    \endlist
-
-    This example may be useful for developers who want to implement their own table
-    models or custom delegates. The process of creating custom delegates for editing
-    item data is covered in the \l{Spin Box Delegate Example}{Spin Box Delegate}
-    example.
-
-    \section1 ImageModel Class Definition
-
-    The \c ImageModel class is defined as follows:
-
-    \snippet itemviews/pixelator/imagemodel.h 0
-
-    Since we only require a simple, read-only table model, we only need to implement
-    functions to indicate the dimensions of the image and supply data to other
-    components.
-
-    \section1 ImageModel Class Implementation
-
-    The constructor is trivial:
-
-    \snippet itemviews/pixelator/imagemodel.cpp 0
-
-    The \c setImage() function sets the image that will be used by the model:
-
-    \snippet itemviews/pixelator/imagemodel.cpp 1
-
-    The QAbstractItemModel::reset() call tells the view(s) that the model
-    has changed.
-
-    The \c rowCount() and \c columnCount() functions return the height and width of
-    the image respectively:
-
-    \snippet itemviews/pixelator/imagemodel.cpp 2
-    \snippet itemviews/pixelator/imagemodel.cpp 3
-
-    Since the image is a simple two-dimensional structure, the \c parent arguments
-    to these functions are unused. They both simply return the relevant size from
-    the underlying image object.
-
-    The \c data() function returns data for the item that corresponds to a given
-    model index in a format that is suitable for a particular role:
-
-    \snippet itemviews/pixelator/imagemodel.cpp 4
-
-    In this implementation, we only check that the model index is valid, and that
-    the role requested is the \l{Qt::ItemDataRole}{DisplayRole}. If so, the function
-    returns the grayscale value of the relevant pixel in the image; otherwise, a null
-    model index is returned.
-
-    This model can be used with QTableView to display the integer brightness values
-    for the pixels in the image. However, we will implement a custom delegate to
-    display this information in a more artistic way.
-
-    The \c headerData() function is also reimplemented:
-
-    \snippet itemviews/pixelator/imagemodel.cpp 5
-
-    We return (1, 1) as the size hint for a header item. If we
-    didn't, the headers would default to a larger size, preventing
-    us from displaying really small items (which can be specified
-    using the \uicontrol{Pixel size} combobox).
-
-    \section1 PixelDelegate Class Definition
-
-    The \c PixelDelegate class is defined as follows:
-
-    \snippet itemviews/pixelator/pixeldelegate.h 0
-
-    This class provides only basic features for a delegate so, unlike the
-    \l{Spin Box Delegate Example}{Spin Box Delegate} example, we subclass
-    QAbstractItemDelegate instead of QItemDelegate.
-
-    We only need to reimplement \l{QAbstractItemDelegate::paint()}{paint()} and
-    \l{QAbstractItemDelegate::sizeHint()}{sizeHint()} in this class.
-    However, we also provide a delegate-specific \c setPixelSize() function so
-    that we can change the delegate's behavior via the signals and slots mechanism.
-
-    \section1 PixelDelegate Class Implementation
-
-    The \c PixelDelegate constructor is used to set up a default value for
-    the size of each "pixel" that it renders. The base class constructor is
-    also called to ensure that the delegate is set up with a parent object,
-    if one is supplied:
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 0
-
-    Each item is rendered by the delegate's
-    \l{QAbstractItemDelegate::paint()}{paint()} function. The view calls this
-    function with a ready-to-use QPainter object, style information that the
-    delegate should use to correctly draw the item, and an index to the item in
-    the model:
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 1
-
-    The first task the delegate has to perform is to draw the item's background
-    correctly. Usually, selected items appear differently to non-selected items,
-    so we begin by testing the state passed in the style option and filling the
-    background if necessary.
-
-    The radius of each circle is calculated in the following lines of code:
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 3
-    \snippet itemviews/pixelator/pixeldelegate.cpp 4
-
-    First, the largest possible radius of the circle is determined by taking the
-    smallest dimension of the style option's \c rect attribute.
-    Using the model index supplied, we obtain a value for the brightness of the
-    relevant pixel in the image. The radius of the circle is calculated by
-    scaling the brightness to fit within the item and subtracting it from the
-    largest possible radius.
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 5
-    \snippet itemviews/pixelator/pixeldelegate.cpp 6
-    \snippet itemviews/pixelator/pixeldelegate.cpp 7
-
-    We save the painter's state, turn on antialiasing (to obtain smoother
-    curves), and turn off the pen.
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 8
-    \snippet itemviews/pixelator/pixeldelegate.cpp 9
-
-    The foreground of the item (the circle representing a pixel) must be
-    rendered using an appropriate brush. For unselected items, we will use a
-    solid black brush; selected items are drawn using a predefined brush from
-    the style option's palette.
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 10
-
-    Finally, we paint the circle within the rectangle specified by the style
-    option and we call \l{QPainter::}{restore()} on the painter.
-
-    The \c paint() function does not have to be particularly complicated; it is
-    only necessary to ensure that the state of the painter when the function
-    returns is the same as it was when it was called. This usually
-    means that any transformations applied to the painter must be preceded by
-    a call to QPainter::save() and followed by a call to QPainter::restore().
-
-    The delegate's \l{QAbstractItemDelegate::}{sizeHint()} function
-    returns a size for the item based on the predefined pixel size, initially set
-    up in the constructor:
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 11
-
-    The delegate's size is updated whenever the pixel size is changed.
-    We provide a custom slot to do this:
-
-    \snippet itemviews/pixelator/pixeldelegate.cpp 12
-
-    \section1 Using The Custom Delegate
-
-    In this example, we use a main window to display a table of data, using the
-    custom delegate to render each cell in a particular way. Much of the
-    \c MainWindow class performs tasks that are not related to item views. Here,
-    we only quote the parts that are relevant. You can look at the rest of the
-    implementation by following the links to the code at the top of this
-    document.
-
-    In the constructor, we set up a table view, turn off its grid, and hide its
-    headers:
-
-    \snippet itemviews/pixelator/mainwindow.cpp 0
-    \dots
-    \snippet itemviews/pixelator/mainwindow.cpp 1
-
-    This enables the items to be drawn without any gaps between them. Removing
-    the headers also prevents the user from adjusting the sizes of individual
-    rows and columns.
-
-    We also set the minimum section size to 1 on the headers. If we
-    didn't, the headers would default to a larger size, preventing
-    us from displaying really small items (which can be specified
-    using the \uicontrol{Pixel size} combobox).
-
-    The custom delegate is constructed with the main window as its parent, so
-    that it will be deleted correctly later, and we set it on the table view.
-
-    \snippet itemviews/pixelator/mainwindow.cpp 2
-
-    Each item in the table view will be rendered by the \c PixelDelegate
-    instance.
-
-    We construct a spin box to allow the user to change the size of each "pixel"
-    drawn by the delegate:
-
-    \snippet itemviews/pixelator/mainwindow.cpp 3
-
-    This spin box is connected to the custom slot we implemented in the
-    \c PixelDelegate class. This ensures that the delegate always draws each
-    pixel at the currently specified size:
-
-    \snippet itemviews/pixelator/mainwindow.cpp 4
-    \dots
-    \snippet itemviews/pixelator/mainwindow.cpp 5
-
-    We also connect the spin box to a slot in the \c MainWindow class. This
-    forces the view to take into account the new size hints for each item;
-    these are provided by the delegate in its \c sizeHint() function.
-
-    \snippet itemviews/pixelator/mainwindow.cpp 6
-
-    We explicitly resize the columns and rows to match the
-    \uicontrol{Pixel size} combobox.
