Member Type Documentation
enum QLineF::IntersectType
| Constant | Value | Description |
|---|---|---|
QLineF::NoIntersection | 0 | Lines do not intersect. |
QLineF::UnboundedIntersection | 2 | Lines intersect, but not within the range defined by their lengths. |
QLineF::BoundedIntersection | 1 | Lnes intersect within the range defined by their lengths. |
Member Function Documentation
qreal QLineF::angle(const QLineF &line) const
Returns the angle (in degrees) between this line and the given line, taking the direction of the lines into account. If the lines do not intersect within their range, it is the intersection point of the extended lines that serves as origin (see QLineF::UnboundedIntersection).
 |  |
When the lines are parallel, this function returns 0 if they have the same direction; otherwise it returns 180.
