const CPoint & | end | |||
) | [virtual] |
add a bezier curve to the path. A subpath must begin before

add a line to the path. A subpath must begin before
void addPath | ( | const CGraphicsPath & | path, | |

) | [virtual] |
add another path to the path. Begins a new subpath if no elements were added before.

add a rectangle to the path. Begins a new subpath if no elements were added before.
void beginSubpath | ( | const CPoint & | start | ) | [virtual] |
begin a new subpath.
