Constructs a CPoint object.

CPoint( ) throw( ); 
CPoint(
    int initX,
    int initY 
) throw( );
CPoint(
    POINT initPt 
) throw( );
CPoint(
    SIZE initSize 
) throw( );
CPoint(
    LPARAM dwPoint 
) throw( );

Parameters

initX
Specifies the value of the x member of CPoint.
initY
Specifies the value of the y member of CPoint.
initPt
POINT structure or CPoint that specifies the values used to initialize CPoint.
initSize
SIZE structure or CSize that specifies the values used to initialize CPoint.
dwPoint
Sets the x member to the low-order word of dwPoint and the y member to the high-order word of dwPoint.

Remarks

If no arguments are given, x and y members are set to 0.

Example

CPoint   ptUndefined;
CPoint   ptTopLeft(0,0);

// works from a POINT, too

POINT   ptHere;
ptHere.x = 35;
ptHere.y = 95;

CPoint   ptMFCHere(ptHere);

// works from A SIZE

SIZE   sHowBig;
sHowBig.cx = 300;
sHowBig.cy = 10;

CPoint ptMFCBig(sHowBig);

// or from a DWORD

DWORD   dwSize;
dwSize = MAKELONG(35, 95);

CPoint ptFromDouble(dwSize);
ASSERT(ptFromDouble == ptMFCHere);
