Member Function Documentation
| QwtText QwtCompassScaleDraw::label | ( | double | value | ) | const [virtual] |
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, or QString::null
- See also:
- labelMap(), setLabelMap()
Reimplemented from QwtAbstractScaleDraw.

| QMap< double, QString > QwtCompassScaleDraw::labelMap | ( | ) | const |
- Returns:
- map, mapping values to labels
- See also:
- setLabelMap()

| 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
