class  NavStars

class  NavStarsCalculator
 

Detailed Description

The Navigational Stars plugin marks the 58 navigational stars of The Nautical Almanac and the 2102-D Rude Star Finder on the sky. Alternatively, the French, German, and Russian selection of navigational stars or alignment stars for various telescopes are also available.

The NavStars class is the main class of the plug-in. It manages the list of navigational stars and manipulate show/hide markers of them. Markers are not objects!

The plugin is also an example of a custom plugin that just marks existing stars.

Configuration

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

Member Function Documentation

◆ configureGui()

bool NavStars::configureGui ( bool  show)
overridevirtual

Detect or show the configuration GUI elements for the module.

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.

◆ deinit()

void NavStars::deinit ( )
overridevirtual

Called before the module will be deleted, and before the OpenGL context is suppressed.

Deinitialize all OpenGL texture in this method.

Reimplemented from StelModule.

◆ draw()

void NavStars::draw ( StelCore core)
overridevirtual

Execute all the drawing functions for this module.

Parameters
corethe core to use for the drawing

Reimplemented from StelModule.

◆ getCallOrder()

double NavStars::getCallOrder ( StelModuleActionName  actionName) const
overridevirtual

Return the value defining the order of call for the given action For example if stars.callOrder[ActionDraw] == 10 and constellation.callOrder[ActionDraw] == 11, the stars module will be drawn before the constellations.

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.

◆ init()

void NavStars::init ( )
overridevirtual

Initialize itself.

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

Implements StelModule.

◆ loadConfiguration()

void NavStars::loadConfiguration ( void  )

Read (or re-read) settings from the main config file.

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

◆ oneRowTwoCells

static QString NavStars::oneRowTwoCells ( const QString &  a,
const QString &  b,
const QString &  extra,
bool  tabulatedView 
)
staticslot

Given two QStrings return in a format consistent with the property setting of "withTables".

Parameters
QStringa The cell left value
QStringb The cell right value
Returns
QString The representation of the extraString info.

◆ restoreDefaultConfiguration()

void NavStars::restoreDefaultConfiguration ( void  )

Set up the plugin with default values.

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

◆ update()

void NavStars::update ( double  deltaTime)
overridevirtual

Update the module with respect to the time.

Parameters
deltaTimethe time increment in second since last call.

Reimplemented from StelModule.
