示例1: testToFillPolygons
void tst_QPainterPath::testToFillPolygons()
{
QPainterPath path;
path.lineTo(QPointF(0, 50));
path.lineTo(QPointF(50, 50));
path.moveTo(QPointF(70, 50));
path.lineTo(QPointF(70, 100));
path.lineTo(QPointF(40, 100));
const QList<QPolygonF> polygons = path.toFillPolygons();
QCOMPARE(polygons.size(), 2);
QCOMPARE(polygons.first().count(QPointF(70, 50)), 0);
