Descripción detallada

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.

Nota:

The examples/dials example shows how to use QwtAnalogClock.

Documentación de las funciones miembro

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

Draw a clock hand

Parámetros:

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().

Parámetros:

painter	Painter
center	Center of the clock
radius	Maximum length for the hands
direction	Dummy, not used.
cg	ColorGroup
