           isNull()

       Definition at line 65 of file qwt_point_3d.h.

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

       Definition at line 84 of file qwt_point_3d.h.

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.

       Definition at line 97 of file qwt_point_3d.h.

   bool QwtPoint3D::operator!= (const QwtPoint3D & other) const [inline]
       Returns
           True if this rect and other are different; otherwise returns false.

       Definition at line 171 of file qwt_point_3d.h.

   bool QwtPoint3D::operator== (const QwtPoint3D & other) const [inline]
       Returns
           True, if this point and other are equal; otherwise returns false.

       Definition at line 165 of file qwt_point_3d.h.

   double & QwtPoint3D::rx () [inline]
       Returns
           A reference to the x-coordinate of the point.

       Definition at line 121 of file qwt_point_3d.h.

   double & QwtPoint3D::ry () [inline]
       Returns
           A reference to the y-coordinate of the point.

       Definition at line 127 of file qwt_point_3d.h.

   double & QwtPoint3D::rz () [inline]
       Returns
           A reference to the z-coordinate of the point.

       Definition at line 133 of file qwt_point_3d.h.

   QPointF QwtPoint3D::toPoint () const [inline]
       Returns
           2D point, where the z coordinate is dropped.

       Definition at line 159 of file qwt_point_3d.h.

   double QwtPoint3D::x () const [inline]
       Returns
           The x-coordinate of the point.

       Definition at line 103 of file qwt_point_3d.h.

   double QwtPoint3D::y () const [inline]
       Returns
           The y-coordinate of the point.

       Definition at line 109 of file qwt_point_3d.h.

   double QwtPoint3D::z () const [inline]
       Returns
           The z-coordinate of the point.
