◆ getCallOrder()

virtual double ConstellationMgr::getCallOrder ( StelModuleActionName actionName ) const

virtual

Parameters

actionName the 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

See also: getConstellationDisplayStyle()

◆ 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

Parameters

inEnglish list 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
