Detailed Description

A MeteorShower object represents one meteor shower on the sky.

Details about the meteor showers are passed using a QVariant which contains a map of data from the json file.

Definition at line 37 of file MeteorShower.hpp.

Constructor & Destructor Documentation

MeteorShower::MeteorShower ( MeteorShowersMgr mgr,
const QVariantMap &  map 
)

Constructor.

Parameters
mapQVariantMap containing all the data about a Meteor Shower.
MeteorShower::~MeteorShower ( )

Destructor.

Member Function Documentation

void MeteorShower::draw ( StelCore core)

Draw.

bool MeteorShower::enabled ( ) const

Checks if this meteor shower is being displayed or not.

Returns
true if it's being displayed
virtual double MeteorShower::getAngularSize ( const StelCore core) const
inlinevirtual

Return the angular radius of a circle containing the object as seen from the observer with the circle center assumed to be at getJ2000EquatorialPos().

Returns
radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

Definition at line 124 of file MeteorShower.hpp.

QString MeteorShower::getDesignation ( ) const

Gets the meteor shower id //!

Returns
designation
virtual QString MeteorShower::getEnglishName ( void  ) const

Definition at line 119 of file MeteorShower.hpp.

virtual Vec3f MeteorShower::getInfoColor ( void  ) const
virtual

Get a color used to display info about the object.

Reimplemented from StelObject.

virtual QVariantMap MeteorShower::getInfoMap ( const StelCore core) const
virtual

Return a map like StelObject, but with a few extra tags:

  • status
  • id
  • type (translated string "meteor shower")
  • speed (km/s)
  • pop-idx (population index)
  • parent
  • zhr-max (information string)

Reimplemented from StelObject.

virtual QString MeteorShower::getInfoString ( const StelCore core,
const InfoStringGroup &  flags 
) const
virtual

Write I18n information about the object in QString.

Parameters
corethe StelCore object to use
flagsa set of InfoStringGroup flags which are used to filter the return value - including specified types of information and altering the output format.
Returns
an HTML string containing information about the StelObject.

Implements StelObject.
