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 ( 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.

QPointF QwtPoint3D::toPoint ( ) const
inline

Rounds 2D point, where the z coordinate is dropped.
