CPoint Class

Similar to the Windows POINT structure.

class CPoint : public tagPOINT

Members

Public Constructors

Name	Description
CPoint::CPoint	Constructs a CPoint.

Public Methods

Name	Description
CPoint::Offset	Adds values to the x and y members of the CPoint.

Public Operators

Name	Description
CPoint::operator -	Returns the difference of a CPoint and a size, or the negation of a point, or the size difference between two points, or the offset by a negative size.
CPoint::operator !=	Checks for inequality between two points.
CPoint::operator +	Returns the sum of a CPoint and a size or point, or a CRect offset by a size.
CPoint::operator +=	Offsets CPoint by adding a size or point.
CPoint::operator -=	Offsets CPoint by subtracting a size or point.
CPoint::operator ==	Checks for equality between two points.

Remarks

It also includes member functions to manipulate CPoint and POINT structures.

A CPoint object can be used wherever a POINT structure is used. The operators of this class that interact with a "size" accept either CSize objects or SIZE structures, since the two are interchangeable.

Note

This class is derived from the tagPOINT structure. (The name tagPOINT is a less commonly used name for the POINT structure.) This means that the data members of the POINT structure, x and y, are accessible data members of CPoint.
