Member Function Documentation

computeEclipticDatePartitions()

static void SkyLine::computeEclipticDatePartitions ( int  year = std::numeric_limits< int >::min() )

static

Compute eclipticOnDatePartitions for.

Parameters

year.

Trigger a call to this from a signal StelCore::dateChangedByYear()

setCulturalPartitions()

void SkyLine::setCulturalPartitions ( QList< QList< double >>  cParts )

inline

setup the small partitions in a ECLIPTIC_CULTURAL or EQUATORIAL_CULTURAL line, in degrees.

Element nr.0 is a vector of the major divisions. It is not used directly, just here for completion. Element nr.1 is a vector of all main divisions of all major divisions. This may be 10-degrees in a 12x30 degree zodiac, or the quarter-lines in the Indian 27-part nakshatras. Element nr.2 is a vector of all minor divisions, like the 5-degrees in a 12x30 degrees zodiac defined as [12 3 2 5]. Element nr.3 is a vector of all sub-minor divisions, like the 1-degrees in a 12x30 degrees zodiac defined as [12 3 2 5]. Up to these 4 lists is supported with drawing ever-smaller sub-ticks
