Detailed Description
An analog clock.
Example.RS 4
#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::HandHand type
See also:
- setHand(), hand()
Constructor & Destructor Documentation
QwtAnalogClock::QwtAnalogClock (QWidget * parent = NULL) [explicit]Constructor
Parameters:
- parent Parent widget
QwtAnalogClock::~QwtAnalogClock () [virtual]
Destructor.
Member Function Documentation
void QwtAnalogClock::drawHand (QPainter * painter, Hand hd, const QPoint & center, int 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
void QwtAnalogClock::drawNeedle (QPainter * painter, const QPoint & center, int radius, double direction, QPalette::ColorGroup cg) 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.
QwtDialNeedle * QwtAnalogClock::hand (Hand hd)Returns:
- Clock hand
Parameters:
- hd Specifies the type of hand
See also:
- setHand()
const QwtDialNeedle * QwtAnalogClock::hand (Hand hd) constReturns:
- Clock hand
Parameters:
- hd Specifies the type of hand
See also:
- setHand()
QwtText QwtAnalogClock::scaleLabel (double value) 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 (Hand hand, 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
