Detailed Description

       A legend label.

       QwtLegendItem represents a curve on a legend. It displays an curve identifier with an
       explaining text. The identifier might be a combination of curve symbol and line. In
       readonly mode it behaves like a label, otherwise like an unstylish push button.
