Detailed Description

Else it behaves like the Julian calendar. setDate can take either 2 or 4 elements. In the first case, month/day are taken from the current Julian calendar date.

Member Function Documentation

getDateStrings()

virtual QStringList OlympicCalendar::getDateStrings ( ) const

virtual

Olympiad, Year

Reimplemented from JulianCalendar.

setDate()

virtual void OlympicCalendar::setDate ( QVector< int >  parts )

virtual

The elements only change years. The calendar is else based on the Julian, so unless given explicitly, months and days in the Julian calendar will not be changed. parts={olympiad, year [, month, day]}

Reimplemented from JulianCalendar.
