CPoint::operator +=
The first overload adds a size to the CPoint.
void operator +=(
SIZE size
) throw( );
void operator +=(
POINT point
) throw( );
Parameters
Remarks
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).
Example
CPoint ptStart(100, 100);
CSize szOffset(35, 35);
ptStart += szOffset;
CPoint ptResult(135, 135);
ASSERT(ptResult == ptStart);
// also works on SIZE
ptStart = CPoint(100, 100);
SIZE sz;
sz.cx = 35;
sz.cy = 35;
ptStart += sz;
ASSERT(ptResult == ptStart);
