Member Function Documentation¶
void QwtAnalogClock::drawHand (QPainter *painter, Handhd, const QPointF ¢er, doubleradius, doubledirection, QPalette::ColorGroupcg) const [protected], [virtual]¶
Draw a clock handParameters:
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
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 ¢er, doubleradius, doubledir, QPalette::ColorGroupcolorGroup) 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
center Center of the clock
radius Maximum length for the hands
dir Dummy, not used.
colorGroup ColorGroup
