QwtPoint3D::QwtPoint3D()[inline]
       Constructs a null point.

       Seealso:isNull()QwtPoint3D::QwtPoint3D(constQwtPoint3D&other)[inline]
       Copy constructor. Constructs a point using the values of the point specified.

   QwtPoint3D::QwtPoint3D(constQPointF&other)[inline]
       Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0.

QwtPoint3D class defines a 3D point in double coordinates.

boolQwtPoint3D::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.

   boolQwtPoint3D::operator!=(constQwtPoint3D&other)const[inline]Returns:
           True if this rect and other are different; otherwise returns false.

   boolQwtPoint3D::operator==(constQwtPoint3D&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.

   QPointFQwtPoint3D::toPoint()const[inline]Returns:
           2D point, where the z coordinate is dropped.

   doubleQwtPoint3D::x()const[inline]Returns:
           The x-coordinate of the point.

   doubleQwtPoint3D::y()const[inline]Returns:
           The y-coordinate of the point.

   doubleQwtPoint3D::z()const[inline]Returns:
           The z-coordinate of the point.
