Use this operator to offset CPoint by a CPoint or CSize object, or to offset a CRect by a CPoint.
CPoint operator +(
SIZE size
) const throw( );
CPoint operator +(
POINT point
) const throw( );
CRect operator +(
const RECT* lpRect
) const throw( );
Parameters
Return Value
A CPoint that is offset by a size, a CPoint that is offset by a point, or a CRect offset by a point.
Remarks
For example, using one of the first two overloads to offset the point CPoint(25, -19) by a point CPoint(15, 5) or size CSize(15, 5) returns the value CPoint(40, -14).
Adding a rectangle to a point returns the rectangle after being offset by the x and y values specified in the point. For example, using the last overload to offset a rectangle CRect(125, 219, 325, 419) by a point CPoint(25, -19) returns CRect(150, 200, 350, 400).
Example
CPoint ptStart(100, 100);
CSize szOffset(35, 35);
CPoint ptEnd;
ptEnd = ptStart + szOffset;
CPoint ptResult(135, 135);
ASSERT(ptResult == ptEnd);
// also works on SIZE
ptStart = CPoint(100, 100);
SIZE sz;
sz.cx = 35;
sz.cy = 35;
ptEnd = ptStart + sz;
ASSERT(ptResult == ptEnd);
