QwtAnalogClock::QwtAnalogClock (QWidget * parent = NULL) [explicit]
Constructor
Parameters:
parent Parent widget
Member Function Documentation
void QwtAnalogClock::drawHand (QPainter * painter, Hand hd, const QPointF & center, double 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
void QwtAnalogClock::drawNeedle (QPainter * painter, const QPointF & center, double radius, double dir,
QPalette::ColorGroup colorGroup) 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
dir Dummy, not used.
colorGroup ColorGroup
