Detailed Description

An abstract base class that should never be used directly, only inherited.

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

◆ create()

static TelescopeClient* TelescopeClient::create ( const QString &  url)
static

example url: My_first_telescope:TCP:J2000:localhost:10000:500000 split to: name = My_first_telescope type = TCP equinox = J2000 params = localhost:10000:500000

The params part is optional. We use QRegularExpression to validate the url and extract the components.

◆ getID()

QString TelescopeClient::getID ( ) const
inlineoverridevirtual

Returns a unique identifier for this object.

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
overridevirtual

TelescopeClient supports the following InfoStringGroup flags:

  • Name
  • RaDecJ2000
  • RaDec
  • PlainText
    Parameters
    corethe StelCore object
    flagsa set of InfoStringGroup items to include in the return value.
    Returns
    a QString containing an HMTL encoded description of the Telescope.

Implements StelObject.

◆ getObjectType()

QString TelescopeClient::getObjectType ( void  ) const
inlineoverridevirtual

Return object's type.

It should be English lowercase name of the astronomical type of the object. The purpose of this string is a distinction or further refinement over object class name retrieved with getType(): Planet objects can be planets, moons, or even the Sun. The Sun should however return "star". Nebula objects should return their actual type like "open cluster", "galaxy", "nebula", ...

Implements StelObject.

◆ isAbortSlewSupported()

virtual bool TelescopeClient::isAbortSlewSupported ( ) const
inlinevirtual

report whether this client can abort a running slew.

Can be used for GUI tweaks

Reimplemented in TelescopeClientDummy, and TelescopeClientASCOM.

◆ isTelescopeSyncSupported()

virtual bool TelescopeClient::isTelescopeSyncSupported ( ) const
inlinevirtual

report whether this client can respond to sync commands.

Can be used for GUI tweaks

Reimplemented in TelescopeClientINDI, and TelescopeClientASCOM.

◆ move()

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

move

Parameters
angle[0,360). 0=South, 90=West, 180=North, 270=East
speed[0,1] The default implementation does nothing but emit a warning.

Reimplemented in TelescopeClientINDI.

◆ telescopeAbortSlew()

virtual void TelescopeClient::telescopeAbortSlew ( )
virtual

Send command to abort slew.

Not all telescopes support this, base implementation only gives a warning. After abort, the current position should be retrieved and displayed.

Reimplemented in TelescopeClientDummy, and TelescopeClientASCOM.

◆ telescopeSync()

virtual void TelescopeClient::telescopeSync ( const Vec3d j2000Pos,
StelObjectP  selectObject 
)
inlinevirtual

Some telescopes can synchronize the telescope with the given position or object.

The base client does nothing. Derived classes may override this command

Reimplemented in TelescopeClientINDI, and TelescopeClientASCOM.
