我从Qgraphicview类中获得哪种类型的单元度量?
我在 QGraphicsView 中找到了两个点,它们映射到我的场景(QGraphicsScene)。这两个点基于用户创建的 mousecliked(mousePressEvent),这些点作为一条线的两个端点。我使用求两点距离的公式获得了直线的距离。我不确定我获得的测量单位是什么,是像素吗?
I have located two points in my QGraphicsView which is map to my scene(QGraphicsScene).The two points are based on the mousecliked(mousePressEvent) made by the user, these points serve as the two endpoints of a line. I obtained the distance of the line using the formula to find the distance of two points. I am not sure what unit of measurement does I obtain, is it in pixel?
