QwtPoint3D(3) Qwt User's Guide QwtPoint3D(3)NAMEQwtPoint3D - QwtPoint3D class defines a 3D point in double coordinates.SYNOPSIS#include <qwt_point_3d.h> Public Member Functions QwtPoint3D () QwtPoint3D (double x, double y, double z) QwtPoint3D (const QwtPoint3D &) QwtPoint3D (const QPointF &) bool isNull () const double x () const double y () const double z () const double & rx () double & ry () double & rz () void setX (double x) void setY (double y) void setZ (double y) QPointF toPoint () const bool operator== (const QwtPoint3D &) const bool operator!= (const QwtPoint3D &) const 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.
