void operator +=( SIZE size );
void operator +=( POINT point );
Parameters
size
Contains a SIZE structure or CSize object.
point
Contains a POINT structure or CPoint object.
Remarks
The first overload adds a size to the CPoint.
The second overload adds a point to the CPoint.
In both cases, addition is done by adding the x (or cx) member of the right-hand operand to the x member of the CPoint and adding the y (or cy) member of the right-hand operand to the y member of the CPoint.
For example, adding CPoint(5, -7) to a variable which contains CPoint(30, 40) changes the variable to CPoint(35, 33).
