QwtPoint3D class defines a 3D point in double coordinates.

Constructs a null point.

See also:

isNull()

Copy constructor. Constructs a point using the values of the point specified.

Constructs a point with x and y coordinates from a 2D point, and a z coordinate of 0.

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.

Returns:

True if this rect and other are different; otherwise returns false.

Returns:

True, if this point and other are equal; otherwise returns false.

Returns:

A reference to the x-coordinate of the point.

Returns:

A reference to the y-coordinate of the point.

Returns:

A reference to the z-coordinate of the point.

Returns:

2D point, where the z coordinate is dropped.

Returns:

The x-coordinate of the point.

Returns:

The y-coordinate of the point.

Returns:

The z-coordinate of the point.
