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

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
¢er, 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 ¢er,
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

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
