| QwtPoint3D::QwtPoint3D |
( |
const QPointF & |
other | ) |
|
|
inline |
Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0.
| bool QwtPoint3D::isNull |

( |
const QwtPoint3D & |
other | ) |
const |
|
inline |
- Returns
- True, if this point and other are equal; otherwise returns false.
| double & QwtPoint3D::rx |
( |
