The CreateRoundRectRgn function creates a rectangular region with rounded corners.
HRGN CreateRoundRectRgn(
int nLeftRect, |
// x-coordinate of the region’s upper-left corner |
int nTopRect, |
// y-coordinate of the region’s upper-left corner |
int nRightRect, |
// x-coordinate of the region’s lower-right corner |
int nBottomRect, |
// y-coordinate of the region’s lower-right corner |
int nWidthEllipse, |
// height of ellipse for rounded corners |
int nHeightEllipse |
// width of ellipse for rounded corners |
); |
If the function succeeds, the return value is the handle to the region.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
