Detailed Description

The Equation of Time plugin shows the solution of the equation of time.

The equation of time describes the discrepancy between two kinds of solar time. These are apparent solar time, which directly tracks the motion of the sun, and mean solar time, which tracks a fictitious "mean" sun with noons 24 hours apart. There is no universally accepted definition of the sign of the equation of time. Some publications show it as positive when a sundial is ahead of a clock; others when the clock is ahead of the sundial. In the English-speaking world, the former usage is the more common, but is not always followed. Anyone who makes use of a published table or graph should first check its sign usage.

Configuration

The plug-ins' configuration data is stored in Stellarium's main configuration file (section [EquationOfTime]).

Member Function Documentation

virtual bool EquationOfTime::configureGui ( bool  show)
virtual

This is to be used with plugins to display a configuration dialog from the plugin list window.

Parameters
showif true, make the configuration GUI visible. If false, hide the config GUI if there is one.
Returns
true if the module has a configuration GUI, else false.

Reimplemented from StelModule.

virtual void EquationOfTime::deinit ( )
virtual

Deinitialize all openGL texture in this method.

Reimplemented from StelModule.

virtual void EquationOfTime::draw ( StelCore core)
virtual
Parameters
corethe core to use for the drawing

Reimplemented from StelModule.

virtual double EquationOfTime::getCallOrder ( StelModuleActionName  actionName) const
virtual
Parameters
actionNamethe 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.

virtual void EquationOfTime::init ( )
virtual

If the initialization takes significant time, the progress should be displayed on the loading bar.

Implements StelModule.

void EquationOfTime::readSettingsFromConfig ( void  )

This will be called from init and also when restoring defaults (i.e. from the configuration dialog / restore defaults button).

void EquationOfTime::restoreDefaults ( void  )

This means clearing out the EquationOfTime section in the main config.ini (if one already exists), and populating it with default values.

virtual void EquationOfTime::update ( double  deltaTime)
inlinevirtual
Parameters
deltaTimethe time increment in second since last call.

Implements StelModule.
