  \class QFontDialog qfontdialog.h
  \ingroup dialogs
  \mainclass
  \brief The QFontDialog class provides a dialog widget for selecting a font.

  The usual way to use this class is to call one of the static convenience
  functions, e.g. getFont().

  Examples:

  \code
    bool ok;
    QFont font = QFontDialog::getFont(
                    &ok, QFont("Helvetica [Cronyx]", 10), this);
    if (ok) {
        // the user clicked OK and font is set to the font the user selected
    } else {
        // the user canceled the dialog; font is set to the initial
        // value, in this case Helvetica [Cronyx], 10
    }
  \endcode

    The dialog can also be used to set a widget's font directly:
  \code
    myWidget.setFont(QFontDialog::getFont(0, myWidget.font()));
  \endcode
  If the user clicks OK the font they chose will be used for myWidget,
  and if they click Cancel the original font is used.
