Detailed Description

This class used to be called Telescope, but it has been renamed to TelescopeClient in order to resolve a compiler/linker conflict with the identically named Telescope class in Stellarium's main code.

Member Function Documentation

◆ getAngularSize()

virtual double TelescopeClient::getAngularSize ( const StelCore core) const
radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

◆ getID()

QString TelescopeClient::getID ( ) const

The ID should be unique for all objects of the same type, but may freely conflict with IDs of other types, so getType() must also be tested.

With this it should be possible to at least identify the same object in a different instance of Stellarium running the same version, but it would even be better if the ID provides some degree of forward-compatibility. For some object types (e.g. planets) this may simply return getEnglishName(), but better candidates may be official designations or at least (stable) internal IDs.

An object may have multiple IDs (different catalog numbers, etc). StelObjectMgr::searchByID() should search through all ID variants, but this method only returns one of them.

Implements StelObject.

◆ getInfoString()

QString TelescopeClient::getInfoString ( const StelCore core,
const InfoStringGroup &  flags 
) const
  • Name
  • RaDecJ2000
  • RaDec
  • PlainText
    corethe StelCore object
    flagsa set of InfoStringGroup items to include in the return value.
    a QString containing an HMTL encoded description of the Telescope.

Implements StelObject.

◆ move()

virtual void TelescopeClient::move ( double  angle,
double  speed 

Reimplemented in TelescopeClientASCOM, and TelescopeClientINDI.
