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 |
); |
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.
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.
