Detailed Description

Display and manage the constellations. It can display constellations lines, names, art textures and boundaries. It also supports several different sky cultures.

Member Function Documentation

◆ deselectConstellation

void ConstellationMgr::deselectConstellation ( const QString &  englishName)
slot

Calling this method will enable isolated selection for the constellations if it is not enabled yet.

Parameters
englishNamethe English name of the constellation
// example of usage in scripts: remove selection from the Orion constellation
Note
all constellations will be hided when list of selected constellations will be empty

◆ getArtIntensityMaximumFov

double ConstellationMgr::getArtIntensityMaximumFov ( ) const
slot

The default is 2.0.

◆ getArtIntensityMinimumFov

double ConstellationMgr::getArtIntensityMinimumFov ( ) const
slot

See LP:#1294483. The default is 1.0.

◆ getCallOrder()

virtual double ConstellationMgr::getCallOrder ( StelModuleActionName  actionName) const
virtual
Parameters
actionNamethe name of the action for which we want the call order
Returns
the value defining the order. The closer to 0 the earlier the module's action will be called

Reimplemented from StelModule.

◆ getConstellationDisplayStyleString

static QString ConstellationMgr::getConstellationDisplayStyleString ( ConstellationMgr::ConstellationDisplayStyle  style)
staticslot

◆ init()

virtual void ConstellationMgr::init ( )
virtual

Reads from the configuration parser object and updates the loading bar as constellation objects are loaded for the required sky culture.

Implements StelModule.

◆ listAllObjects()

virtual QStringList ConstellationMgr::listAllObjects ( bool  inEnglish) const
virtual
Parameters
inEnglishlist names in English (true) or translated (false)
Returns
a list of matching object name by order of relevance, or an empty list if nothing matches

Implements StelObjectModule.

◆ searchAround()

virtual QList<StelObjectP> ConstellationMgr::searchAround ( const Vec3d v,
double  limitFov,
const StelCore core 
) const
virtual

The function searches in a disk of diameter limitFov centered on v. Only visible objects (i.e. currently displayed on screen) should be returned.

Parameters
vequatorial position at epoch J2000 (without aberration).
limitFovangular diameter of the searching zone in degree.
corethe StelCore instance to use.
Returns
the list of all the displayed objects contained in the defined zone.

Implements StelObjectModule.

namethe english object name

Implements StelObjectModule.

◆ searchByName()

virtual StelObjectP ConstellationMgr::searchByName ( const QString &  name) const
virtual
Returns
the matching constellation if exists or Q_NULLPTR
