NAME
QwtAnalogClock
SYNOPSIS
Inherits QwtDial.
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 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 - Definition at line 191 of file qwt_analog_clock.cpp.
- References QwtDialNeedle::draw(), and hand().
- Referenced by drawNeedle().
- 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.
