Detailed Description
A special scale draw made for QwtCompass.
QwtCompassScaleDraw maps values to strings using a special map, that can be modified by the application
The default map consists of the labels N, NE, E, SE, S, SW, W, NW.

Map a value to a corresponding label
- Parameters
-
value Value that will be mapped
label() looks in the labelMap() for a corresponding label for value or returns an null text.
- Returns
- Label
- See also
- labelMap(), setLabelMap()
Reimplemented from QwtAbstractScaleDraw.
Definition at line 102 of file qwt_compass.cpp.
| QMap< double, QString > QwtCompassScaleDraw::labelMap | ( | ) | const |
- Returns
- map, mapping values to labels
- See also
- setLabelMap()
Definition at line 85 of file qwt_compass.cpp.
| void QwtCompassScaleDraw::setLabelMap | ( | const QMap< double, QString > & | map | ) |
Set a map, mapping values to labels.
- Parameters
-
map Value to label map
The values of the major ticks are found by looking into this map. The default map consists of the labels N, NE, E, SE, S, SW, W, NW.
- Warning
- The map will have no effect for values that are no major tick values. Major ticks can be changed by QwtScaleDraw::setScale
