Detailed Description

       An analog clock.

       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);

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

       Note:
           The examples/dials example shows how to use QwtAnalogClock.

Member Enumeration Documentation

   enum QwtAnalogClock::Hand
       Hand type

       See also:
           setHand(), hand()

Constructor & Destructor Documentation

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

       Parameters:
           parent Parent widget

Member Function Documentation

   void QwtAnalogClock::drawHand (QPainter *painter, Handhd, const QPoint &center, intradius,
       doubledirection, QPalette::ColorGroupcg) 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

   void QwtAnalogClock::drawNeedle (QPainter *painter, const QPoint &center, intradius,
       doubledirection, QPalette::ColorGroupcg) const [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.
           cg ColorGroup

       See also:
           drawHand()

       Reimplemented from QwtDial.

   const QwtDialNeedle * QwtAnalogClock::hand (Handhd) const
       Returns:
           Clock hand

       Parameters:
           hd Specifies the type of hand

       See also:
           setHand()

   QwtDialNeedle * QwtAnalogClock::hand (Handhd)
       Returns:
           Clock hand

       Parameters:
           hd Specifies the type of hand

       See also:
           setHand()

   QwtText QwtAnalogClock::scaleLabel (doublevalue) const [protected],  [virtual]
       Find the scale label for a given value

       Parameters:
           value Value

       Returns:
           Label

       Reimplemented from QwtDial.

   void QwtAnalogClock::setCurrentTime () [slot]
       Set the current time. This is the same as QwtAnalogClock::setTime(), but Qt < 3.0 can't
       handle default parameters for slots.

   void QwtAnalogClock::setHand (Handhand, QwtDialNeedle *needle) [virtual]
       Set a clockhand

       Parameters:
           hand Specifies the type of hand
           needle Hand

       See also:
           hand()

   void QwtAnalogClock::setTime (const QTime &time = QTime::currentTime()) [slot]
       Set a time

       Parameters:
           time Time to display
