QwtSymbol::QwtSymbol | ( | ) |
Default Constructor
The symbol is constructed with gray interior, black outline with zero width, no size and style 'NoSymbol'.

Specify the symbol's size.
If the 'h' parameter is left out or less than 0, and the 'w' parameter is greater than or equal to 0, the symbol size will be set to (w,w).
w | width | |
h | height (defaults to -1) |

void QwtSymbol::setBrush | ( | const QBrush & | br | ) |
Assign a brush.
The brush is used to draw the interior of the symbol.

void QwtSymbol::draw | ( | QPainter * | painter, | |
const QRect & | r | |||
) | const [virtual] |
Draw the symbol into a bounding rectangle.
This function assumes that the painter has been initialized with brush and pen before. This allows a much more performant implementation when painting many symbols with the same brush and pen like in curves.
painter | Painter | |
r | Bounding rectangle |
