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);

Note: The examples/dials example shows how to use QwtAnalogClock.

◆ QwtAnalogClock()

QwtAnalogClock::QwtAnalogClock ( QWidget * parent = NULL )

explicit

Constructor

Parameters

parent Parent widget

◆ ~QwtAnalogClock()

QwtAnalogClock::~QwtAnalogClock ( )

virtual

Destructor.

Member Function Documentation

◆ drawHand()

void QwtAnalogClock::drawHand	(	QPainter *	painter,
		Hand	hd,
		const QPointF &	center,
		double	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

Definition at line 239 of file qwt_analog_clock.cpp.

◆ drawNeedle()

void QwtAnalogClock::drawNeedle	(	QPainter *	painter,
		const QPointF &	center,
		double	radius,
		double	direction,
		QPalette::ColorGroup	colorGroup
	)		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.
colorGroup	ColorGroup

See also: drawHand()

Reimplemented from QwtDial.

Definition at line 202 of file qwt_analog_clock.cpp.

QwtDialNeedle * QwtAnalogClock::hand ( Hand hd )

Returns: Clock hand

Parameters

hd	Specifies the type of hand

See also: setHand()

Definition at line 146 of file qwt_analog_clock.cpp.

◆ hand() [2/2]

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

void QwtAnalogClock::setCurrentTime ( )

slot

Set the current time.

Definition at line 167 of file qwt_analog_clock.cpp.

◆ setHand()

void QwtAnalogClock::setHand	(	Hand	hand,
