Member Function Documentation

double ConstellationMgr::getArtIntensityMaximumFov ( ) const
slot

The default is 2.0.

double ConstellationMgr::getArtIntensityMinimumFov ( ) const
slot

See LP:#1294483. The default is 1.0.

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.

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

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
