  \brief An analog clock

  \image html analogclock.png

  \par Example
  \verbatim #include <qwt_analog_clock.h>

  QwtAnalogClock *clock = new QwtAnalogClock(...);
  clock->scaleDraw()->setPenWidth(3);
  clock->setLineWidth(6);
  clock->setFrameShadow(QwtDial::Sunken);
  clock->setTime();

  // update the clock every second
  QTimer *timer = new QTimer(clock);
  timer->connect(timer, SIGNAL(timeout()), clock, SLOT(setCurrentTime()));
  timer->start(1000);

  \endverbatim

  Qwt is missing a set of good looking hands.
  Contributions are very welcome.

  \note The examples/dials example shows how to use QwtAnalogClock.
