CRect::PtInRect

  • 项目

BOOLPtInRect(POINTpoint**)const;**

Return Value

Nonzero if the point lies within CRect; otherwise 0.

Parameters

point

Contains a POINT structure or CPoint object.

Remarks

Determines whether the specified point lies within CRect. A point is within CRect if it lies on the left or top side or is within all four sides. A point on the right or bottom side is outside CRect.

Note   The rectangle must be normalized or this function may fail. You can call NormalizeRect to normalize the rectangle before calling this function.

Example

CRect rect(5, 5, 100, 100);
CPoint pt1(35, 50);
CPoint pt2(125, 298);

// this is true, because pt1 is inside the rectangle
ASSERT(rect.PtInRect(pt1));

// this is NOT true, because pt2 is outside the rectangle
ASSERT(!rect.PtInRect(pt2));

// note that the right and the bottom aren't inside
ASSERT(!rect.PtInRect(CPoint(35, 100)));
ASSERT(!rect.PtInRect(CPoint(100, 98)));

// but the top and the
ASSERT(rect.PtInRect(CPoint(5, 65)));
ASSERT(rect.PtInRect(CPoint(88, 5)));

// and that PtInRect() works against a POINT, too
POINT pt;
pt.x = 35;
pt.y = 50;
ASSERT(rect.PtInRect(pt));
