Detailed Description

An analog clock.

analogclock.png
Example
QwtAnalogClock *clock = new QwtAnalogClock(...);
clock->scaleDraw()->setPenWidth(3);
clock->setLineWidth(6);
clock->setTime();
// update the clock every second
QTimer *timer = new QTimer(clock);
timer->connect(timer, SIGNAL(timeout()), clock, SLOT(setCurrentTime()));
timer->start(1000);
Note
The examples/dials example shows how to use QwtAnalogClock.

Member Function Documentation

void QwtAnalogClock::drawHand ( QPainter *  painter,
Hand  hd,
const QPointF &  center,
double  radius,
double  direction,
QPalette::ColorGroup  cg 
) const
protectedvirtual

Draw a clock hand

Parameters
painterPainter
hdSpecify the type of hand
centerCenter of the clock
radiusMaximum length for the hands
directionDirection of the hand in degrees, counter clockwise
cgColorGroup

Definition at line 232 of file qwt_analog_clock.cpp.

void QwtAnalogClock::drawNeedle ( QPainter *  painter,
const QPointF &  center,
double  radius,
double  dir,
QPalette::ColorGroup  colorGroup 
) const
protectedvirtual

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
painterPainter
centerCenter of the clock
radiusMaximum length for the hands
dirDummy, not used.
