Detailed Description

Widget class for graphical representation of sequence lines.

A sequence lifeline consists of the object widget at the top and a vertical line starting at the bottom edge of the object widget at half its width. The line grows downward when sequence messages are added such that the line always extends far enough to act as the background for all messages. This class represents only the line part of the lifeline.
