RoundRect info  Overview  Group

The RoundRect function draws a rectangle with rounded corners. The rectangle is outlined by using the current pen and filled by using the current brush.

BOOL RoundRect(

HDC hdc,	// handle of device context
int nLeftRect,	// x-coord. of bounding rectangle’s upper-left corner
int nTopRect,	// y-coord. of bounding rectangle’s upper-left corner
int nRightRect,	// x-coord. of bounding rectangle’s lower-right corner
int nBottomRect,	// y-coord. of bounding rectangle’s lower-right corner
int nWidth,	// width of ellipse used to draw rounded corners
int nHeight	// height of ellipse used to draw rounded corners
);

Parameters

hdc

Identifies the device context.

nLeftRect

Specifies the x-coordinate of the upper-left corner of the rectangle.

nTopRect

Specifies the y-coordinate of the upper-left corner of the rectangle.

nRightRect

Specifies the x-coordinate of the lower-right corner of the rectangle.

nBottomRect

Specifies the y-coordinate of the lower-right corner of the rectangle.

nWidth

Specifies the width of the ellipse used to draw the rounded corners.

nHeight

Specifies the height of the ellipse used to draw the rounded corners.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The current position is neither used nor updated by this function.

Windows 95: The sum of the coordinates of the bounding rectangle cannot exceed 32,767. The sum of nLeftRect and nRightRect or nTopRect and nBottomRect parameters cannot exceed 32,767.
