       Example


           #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);

Constructor & Destructor Documentation
   QwtAnalogClock::QwtAnalogClock (QWidget * parent = NULL) [explicit]
       Constructor

       Parameters
           parent Parent widget

Member Function Documentation
   void QwtAnalogClock::drawHand (QPainter * painter, Hand hd, const QPointF &
       center, double radius, double direction, QPalette::ColorGroup cg) const
       [protected],  [virtual]
       Draw a clock hand

       Parameters
           painter Painter
           hd Specify the type of hand
           center Center of the clock
           radius Maximum length for the hands
           direction Direction of the hand in degrees, counter clockwise
           cg ColorGroup

       Definition at line 239 of file qwt_analog_clock.cpp.

   void QwtAnalogClock::drawNeedle (QPainter * painter, const QPointF &
       center, double radius, double direction, QPalette::ColorGroup
       colorGroup) const [override],  [protected],  [virtual]
       Draw the needle. A clock has no single needle but three hands instead.
       drawNeedle() translates value() into directions for the hands and calls
       drawHand().

       Parameters
           painter Painter
           center Center of the clock
           radius Maximum length for the hands
           direction Dummy, not used.
           colorGroup ColorGroup
