A numeric formatter which returns a text representation of a direction/bearing.
QVariantMap configuration(const QgsReadWriteContext &context) const override
Returns the current configuration of the formatter.
static void setBearingFormat(const QgsBearingNumericFormat *format)
Sets the default bearing format, which controls how angular bearings are displayed.
static QgsBearingNumericFormat * bearingFormat()
Returns the default bearing format, which controls how angular bearings are displayed.
The class is used as a container of context for various read/write operations on other objects.
