Detailed Description

Main class of the Solar System Editor plug-in.

Author: Bogdan Marinov

Solar System bodies are identified by their names in Stellarium, but entries in the configuration file are identified by their group (section) names. This makes more difficult the detection of duplicates.

Definition at line 59 of file SolarSystemEditor.hpp.

Member Enumeration Documentation

enum SolarSystemEditor::UpdateFlag

Flags to control the updateSolarSystemConfigurationFile() function.

Enumerator
UpdateNameAndNumber	Update the name and minor planet number, if any.
UpdateType	Update objects that lack the "type" parameter.
UpdateOrbitalElements	Update the orbital elements, including the orbit function.
UpdateMagnitudeParameters	Update the values in the two parameter system, or add them if they are missing and the type allows.

Definition at line 181 of file SolarSystemEditor.hpp.

Member Function Documentation

bool SolarSystemEditor::appendToSolarSystemConfigurationFile ( SsoElements object )

Adds a new entry at the end of the user solar system configuration file.

This function writes directly to the file. See the note on why QSettings was not used in the description of appendToSolarSystemConfigurationFile(QList<SsoElements>) Duplicates are removed: If any section in the file matches the "section_name" value of the inserted entry, it is removed.

bool SolarSystemEditor::appendToSolarSystemConfigurationFile ( QList< SsoElements > )

Adds new entries at the end of the user solar system configuration file.

This function writes directly to the file. QSettings was not used, as:

Using QSettings with QSettings::IniFormat causes the list in the "color" field (e.g. "1.0, 1.0, 1.0") to be wrapped in double quotation marks (Stellarium requires no quotation marks).
Using QSettings with StelIniFormat causes unaccepptable append times when the file grows (>~40 entries). This most probably happens because StelIniParser uses QMap internally for the entry list. QMap orders its keys (in the case of strings - alphabetically) and it has to find the appropriate place in the ordering for every new key, which takes more and more time as the list grows.

Duplicates are removed: If any section in the file matches the "section_name" value of a new entry, it is removed. Invalid entries in the list (that don't contain a value for "section_name" or it is an empty string) are skipped and the processing continues from the next entry.

virtual bool SolarSystemEditor::configureGui ( bool show )

virtual

called when the "configure" button in the "Plugins" tab is pressed

virtual void SolarSystemEditor::deinit ( )

virtual

called before the plug-in is un-loaded.

Useful for stopping processes, unloading textures, etc.

virtual void SolarSystemEditor::draw ( StelCore * core )

virtual

draws on the view port.

Dialog windows don't need explicit drawing, it's done automatically. If a plug-in draws on the screen, it should be able to respect the night vision mode.

QString SolarSystemEditor::getCustomSolarSystemFilePath ( ) const

inline

returns the path

Definition at line 218 of file SolarSystemEditor.hpp.

QHash<QString,QString> SolarSystemEditor::getDefaultSsoIdentifiers ( )

inline

Returns the names of the objects listed in the default ssystem.ini.

The default solar system configuration file is assumed to be the one in the installation directory.

Definition at line 198 of file SolarSystemEditor.hpp.

virtual void SolarSystemEditor::init ( )

virtual

called when the plug-in is loaded.

All initializations should be done here.

Implements StelModule.

QHash<QString,QString> SolarSystemEditor::listAllLoadedSsoIdentifiers ( )

Lists the objects listed in the current user ssystem.ini.

As the name suggests, the list is compiled when the function is run.

SolarSystemEditor::Q_DECLARE_FLAGS	(	UpdateFlags	,
		UpdateFlag
	)

Updates entries in the user solar system configuration file.

Parameters

objects	a list of data for already existing objects (non-existing ones are skipped);
flags	flags controlling what is being updated. See UpdateFlag.

Returns: false if the operation has failed completely for some reason.

SsoElements SolarSystemEditor::readMpcOneLineCometElements ( QString oneLineElements )

Reads a single comet's orbital elements from a string.

This function converts a line of comet orbital elements in MPC format to a hash in Stellarium's ssystem.ini format. The MPC's one-line orbital elements format for comets is described on their website: http://www.minorplanetcenter.org/iau/info/CometOrbitFormat.html

Returns: an empty hash if there is an error or the source string is not a valid line in MPC format.

QList<SsoElements> SolarSystemEditor::readMpcOneLineCometElementsFromFile ( QString filePath )

Reads a list of comet orbital elements from a file.

This function reads a list of comet orbital elements in MPC's one-line format from a file (one comet per line) and converts it to a list of hashes in Stellarium's ssystem.ini format. Example source file is the list of observable comets on the MPC's site: http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft00Cmt.txt readMpcOneLineCometElements() is used internally to parse each line.

SsoElements SolarSystemEditor::readMpcOneLineMinorPlanetElements ( QString oneLineElements )

Reads a single minor planet's orbital elements from a string.

This function converts a line of minor planet orbital elements in MPC format to a hash in Stellarium's ssystem.ini format. The MPC's one-line orbital elements format for minor planets is described on their website: http://www.minorplanetcenter.org/iau/info/MPOrbitFormat.html

Returns: an empty hash if there is an error or the source string is not a valid line in MPC format.

QList<SsoElements> SolarSystemEditor::readMpcOneLineMinorPlanetElementsFromFile ( QString filePath )

Reads a list of minor planet orbital elements from a file.

This function reads a list of minor planets orbital elements in MPC's one-line format from a file (one comet per line) and converts it to a list of hashes in Stellarium's ssystem.ini format. Example source file is the list of bright asteroids on the MPC's site: http://www.minorplanetcenter.org/iau/Ephemerides/Bright/2010/Soft00Bright.txt readMpcOneLineMinorPlanetElements() is used internally to parse each line.

SsoElements SolarSystemEditor::readXEphemOneLineElements ( QString oneLineElements )

Reads a single object's orbital elements from a string.

This function converts a line of orbital elements in XEphem format to a hash in Stellarium's ssystem.ini format. http://www.clearskyinstitute.com/xephem/help/xephem.html#mozTocId468501 It recognises only the 'e', 'h' and 'p' types of orbits in XEphem's format (comets and minor planets). It is used in handling on-line search queries to the MPC's Minor Planet and Comet Ephemeris System, as using the MPC format causes long object names to be truncated due to the fixed width of the columns. An object's type (comet or asteroid) is determined based on its name.

QList<SsoElements> SolarSystemEditor::readXEphemOneLineElementsFromFile ( QString filePath )

Reads a list of Solar System object orbital elements from a file.

This function reads a list of Solar System object orbital elements in XEphem's one-line format (one object per line, comment lines starting with # are skipped) and converts it to a list of hashes in Stellarium's ssystem.ini format. XEphem's file format is described in its manual: http://www.clearskyinstitute.com/xephem/help/xephem.html#mozTocId468501 Example source file can be any of the lists of objects on the MPC site: http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft03Cmt.txt http://www.minorplanetcenter.org/iau/Ephemerides/Bright/2010/Soft03Bright.txt readXEphemOneLineElements() is used internally to parse each line.

bool SolarSystemEditor::removeSsoWithName ( QString name )

Removes an object from the user Solar System configuration file.

Reloads the Solar System on successfull removal.

name true name of the object ("name" parameter in the configuration file)
Returns
true if the entry has been removed successfully or there is no such entry

false if there was an error

void SolarSystemEditor::resetSolarSystemToDefault ( )

slot

Resets the Solar System configuration file and reloads the Solar System.
