示例1: draw
void RadialAnimation::draw(Painter &p, const QRect &inner, int32 thickness, const style::color &color) {
float64 o = p.opacity();
p.setOpacity(o * _opacity);
QPen pen(color->p), was(p.pen());
pen.setWidth(thickness);
p.setPen(pen);
int32 len = MinArcLength + a_arcEnd.current();
int32 from = QuarterArcLength - a_arcStart.current() - len;
if (rtl()) {
from = QuarterArcLength - (from - QuarterArcLength) - len;
if (from < 0) from += FullArcLength;
}
