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

See also:: setHand(), hand()

Constructor & Destructor Documentation

QwtAnalogClock::QwtAnalogClock ( QWidget * parent = NULL )

explicit

Constructor

Parameters:

parent Parent widget

Member Function Documentation

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

protectedvirtual

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

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:

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.

const QwtDialNeedle * QwtAnalogClock::hand ( Hand hd ) const

Returns:: Clock hand

Parameters:

hd	Specifies the type of hand

See also:: setHand()

QwtDialNeedle * QwtAnalogClock::hand ( Hand hd )

Returns:: Clock hand

Parameters:

hd	Specifies the type of hand

See also:: setHand()

QwtText QwtAnalogClock::scaleLabel ( double value ) const

protectedvirtual

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
