详细描述

Directed rectangle representing bounding rectangle and orientation of a column

QwtColumnRect is a data structure that stores the horizontal and vertical intervals defining a column's extent, along with a direction that indicates how the column should be drawn. It is used by QwtColumnSymbol to determine the column's orientation and boundaries.

成员枚举类型说明

Direction

enum QwtColumnRect::Direction
