Detailed Description
QwtPoint3D class defines a 3D point in double coordinates.
Constructor &; Destructor Documentation
QwtPoint3D::QwtPoint3D () [inline] Constructs a null point.
See also:
isNull()
QwtPoint3D::QwtPoint3D (doublex, doubley, doublez = 0.0) [inline]
Constructs a point with coordinates specified by x, y and z.
QwtPoint3D::QwtPoint3D (const QwtPoint3D &other) [inline] Copy constructor. Constructs a point using the values of the point specified.
QwtPoint3D::QwtPoint3D (const QPointF &other) [inline] Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0.
Member Function Documentation
bool QwtPoint3D::isNull () const [inline] Returns true if the point is null; otherwise returns false.
A point is considered to be null if x, y and z-coordinates are equal to zero.
bool QwtPoint3D::operator!= (const QwtPoint3D &other) const [inline]
Returns true if this rect and other are different; otherwise returns false.
bool QwtPoint3D::operator== (const QwtPoint3D &other) const [inline]
Returns true if this point and other are equal; otherwise returns false.
double & QwtPoint3D::rx () [inline]
Returns a reference to the x-coordinate of the point.
double & QwtPoint3D::ry () [inline]
Returns a reference to the y-coordinate of the point.
double & QwtPoint3D::rz () [inline]
Returns a reference to the z-coordinate of the point.
void QwtPoint3D::setX (doublex) [inline]
Sets the x-coordinate of the point to the value specified by x.
void QwtPoint3D::setY (doubley) [inline]
Sets the y-coordinate of the point to the value specified by y.
void QwtPoint3D::setZ (doubley) [inline]
Sets the z-coordinate of the point to the value specified by z.
QPointF QwtPoint3D::toPoint () const [inline] Rounds 2D point, where the z coordinate is dropped.
double QwtPoint3D::x () const [inline]
Returns the x-coordinate of the point.
double QwtPoint3D::y () const [inline]
Returns the y-coordinate of the point.
double QwtPoint3D::z () const [inline]
Returns the z-coordinate of the point.
