Member Enumeration Documentation

   enum QwtIntervalSymbol::Style
       Symbol style.

       Enumerator:

       NoSymbol
              No Style. The symbol cannot be drawn.

       Bar    The symbol displays a line with caps at the beginning/end. The size of the caps
              depends on the symbol width().

       Box    The symbol displays a plain rectangle using pen() and brush(). The size of the
              rectangle depends on the translated interval and the width(),

       UserSymbol
              Styles >= UserSymbol are reserved for derived classes of QwtIntervalSymbol that
              overload draw() with additional application specific symbol types.
