如何测试与qgraphicspathitem大纲的接近程度?

发布问题后,我找到了以下解决方案:

    path = QPainterPath(...)   # Path we are testing against
    point = QPointF(...)       # Current position

    stroker = QPainterPathStroker()
    stroker.setWidth(10)        # Distance which we consider "on" the path 
    stroke = stroker.createStroke(path)

    if stroke.contains(point):
        # point is on path
