QwtAnalogClock -

#include <qwt_analog_clock.h>

Inherits QwtDial.


enum Hand { SecondHand, MinuteHand, HourHand, NHands }


void setCurrentTime ()
void setTime (const QTime &=QTime::currentTime())


QwtAnalogClock (QWidget *parent=NULL)
virtual ~QwtAnalogClock ()
const QwtDialNeedle * hand (Hand) const
QwtDialNeedle * hand (Hand)
virtual void setHand (Hand, QwtDialNeedle *)


virtual void drawHand (QPainter *, Hand, const QPoint &, int radius, double direction, QPalette::ColorGroup) const
virtual void drawNeedle (QPainter *, const QPoint &, int radius, double direction, QPalette::ColorGroup) const

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.

Hand type

See also:

setHand(), hand()

Constructor

Parameters:

parent Parent widget

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

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.

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.

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

Set a clockhand

Parameters:

hand Specifies the type of hand
needle Hand

See also:

hand()

Set a time

Parameters:

time Time to display
