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.
