53/** \brief functor used to draw a custom JKQTPGraphSymbols
54 * \ingroup jkqtptools_drawing
55 *
56 * Draw the symbol with these properties:
57 * - center at (0,0)
58 * - width 1, i.e. x=-0.5...0.5
59 * - height 1, i.e. y=-0.5...0.5
60 * - you can assume that a proper pen and brush is set with the correct properties
61 * - scaling to the final size is donw by JKQTPPlotSymbol()
62 * - drawing is protected by surronding \c p.save(); and \c p.restore(); in JKQTPPlotSymbol()
63 * .
64 *
65 * As an example, the following code-snippet:
66 * \code
67 * [](QPainter& p) {
68 * p.drawEllipse(QPointF(-0.2, -0.2), 0.3, 0.3);
69 * p.setBrush(Qt::NoBrush);
70 * p.drawEllipse(QPointF(0.2, -0.2), 0.3, 0.3);
71 * p.drawEllipse(QPointF(0, 0.2), 0.3, 0.3);
72 * };
73 * \endcode
74 * generates this symbol: \image html symbols/symbol_custom.png
