CRect::operator -=

void operator -=( POINT point );

void operator -=( SIZE size );

void operator -=( LPCRECT lpRect );

Parameters

point

A POINT structure or CPoint object that specifies the number of units to move the rectangle.

size

A SIZE structure or CSize object that specifies the number of units to move the rectangle.

lpRect

Points to a RECT structure or CRect object that contains the number of units to deflate each side of CRect.

Remarks

The first two overloads move CRect by the specified offsets. The parameter’s x and y (or cx and cy) values are subtracted from CRect.

The third overload deflates CRect by the number of units specifed in each member of the parameter. Note that this overload functions like DeflateRect.

Example

CRect   rect1(100, 235, 200, 335);
CPoint   pt(35, 65);

rect1 -= pt;

CRect   rectResult(65, 170, 165, 270);
ASSERT(rect1 == rectResult);
