25 \brief A class for drawing markers
26
27 A marker can be a horizontal line, a vertical line,
28 a symbol, a label or any combination of them, which can
29 be drawn around a center point inside a bounding rectangle.
30
31 The setSymbol() member assigns a symbol to the marker.
32 The symbol is drawn at the specified point.
33
34 With setLabel(), a label can be assigned to the marker.
35 The setLabelAlignment() member specifies where the label is
36 drawn. All the Align*-constants in Qt::AlignmentFlags (see Qt documentation)
37 are valid. The interpretation of the alignment depends on the marker's
38 line style. The alignment refers to the center point of
39 the marker, which means, for example, that the label would be printed
40 left above the center point if the alignment was set to
41 Qt::AlignLeft | Qt::AlignTop.
42
43 \note QwtPlotTextLabel is intended to align a text label
44 according to the geometry of canvas
45 ( unrelated to plot coordinates )
