         Display the pixmap when the

    \value Active
         Display the pixmap when the

        the user is interacting with the icon, for example, moving the

  \class QIcon

  \brief The QIcon class provides scalable icons in different modes
  and states.

  \ingroup multimedia
  \ingroup shared
  \mainclass

  A QIcon can generate smaller, larger, active, and disabled pixmaps
  from the set of pixmaps it is given. Such pixmaps are used by Qt
  widgets to show an icon representing a particular action.

  The simplest use of QIcon is to create one from a QPixmap file or
  resource, and then use it, allowing Qt to work out all the required
  icon styles and sizes. For example:

  \code
    QToolButton *button = new QToolButton;
    button->setIcon(QIcon("open.xpm"));
  \endcode

  Use the QImageReader::supportedImageFormats() and
  QImageWriter::supportedImageFormats() functions to retrieve a
  complete list of the supported file formats.

  When you retrieve a pixmap using pixmap(QSize, Mode, State), and no
  pixmap for this given size, mode and state has been added with
  addFile() or addPixmap(), then QIcon will generate one on the
  fly. This pixmap generation happens in a QIconEngine. The default
  engine scales pixmaps down if required, but never up, and it uses
  the current style to calculate a disabled appearance. By using
  custom icon engines, you can customize every aspect of generated
  icons. With QIconEnginePlugin it is possible to register different
  icon engines for different file suffixes, so you could provide a SVG
  icon engine or any other scalable format.

  \section1 Making Classes that Use QIcon

  If you write your own widgets that have an option to set a small
  pixmap, consider allowing a QIcon to be set for that pixmap.  The
  Qt class QToolButton is an example of such a widget.

  Provide a method to set a QIcon, and when you draw the icon, choose
  whichever pixmap is appropriate for the current state of your widget.
  For example:
  \code
    void MyWidget::drawIcon(QPainter *painter, QPoint pos)
    {
        QPixmap pixmap = icon.pixmap(QSize(22, 22),
                                       isEnabled() ? QIcon::Normal
                                                   : QIcon::Disabled,
                                       isOn() ? QIcon::On
                                              : QIcon::Off);
        painter->drawPixmap(pos, pixmap);
    }
  \endcode

  You might also make use of the \c Active mode, perhaps making your
  widget \c Active when the mouse is over the widget (see \l
  QWidget::enterEvent()), while the mouse is pressed pending the
  release that will activate the function, or when it is the currently
  selected item. If the widget can be toggled, the "On" mode might be
  used to draw a different icon.
