RoundRect
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(

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.
