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.

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()
