Question

POINT和CPoint有甚么区别！？

Answer 1

typedef struct tagPOINT{LONG x;LONG y;} POINT, *PPOINT, NEAR *NPPOINT, FAR *LPPOINT;//CPoint类复杂一些 class CPoint : public tagPOINT{public:// Constructors // create an uninitialized pointCPoint();// create from two integers CPoint(int initX, int initY); // create from another point CPoint(POINT initPt); // create from a size CPoint(SIZE inITSize); // create from a dword: x = LOWORD(dw) y = HIWORD(dw) CPoint(DWORD dwPoint);// Operations// translate the point void Offset(int xOffset, int yOffset); void Offset(POINT point); void Offset(SIZE size); BOOL operator==(POINT point) const; BOOL operator!=(POINT point) const; void operator+=(SIZE size); void operator-=(SIZE size); void operator+=(POINT point); void operator-=(POINT point);// Operators returning CPoint values CPoint operator+(SIZE size) const; CPoint operator-(SIZE size) const; CPoint operator-() const; CPoint operator+(POINT point) const;// Operators returning CSize values CSize operator-(POINT point) const;// Operators returning CRect values CRect operator+(const RECT* lpRect) const; CRect operator-(const RECT* lpRect) const;};. 编程论坛 5 个网友回答： MSDN上都有。 .
