Detailed Description

Singleton main Stellarium application class.

This is the central class of Stellarium. Only one singleton instance of this class is created and can be accessed from anywhere else. This class is the access point to several "Manager" class which provide application-wide services for managment of font, textures, localization, sky culture, and in theory all other services used by the other part of the program.

The StelApp class is also the one managing the StelModule in a generic manner by calling their update, drawing and other methods when needed.

Constructor & Destructor Documentation

StelApp::StelApp ( QObject *  parent = NULL  ) 

Create and initialize the main Stellarium application.

argc The number of command line parameters
argv an array of char* command line arguments
parent the QObject parent The configFile will be search for in the search path by the StelFileMgr, it is therefor possible to specify either just a file name or path within the search path, or use a full path or even a relative path to an existing file

virtual StelApp::~StelApp (  )  [virtual]

Deinitialize and destroy the main Stellarium application.

StelAudioMgr* StelApp::getStelAudioMgr (  )  [inline]

Get the audio manager.

StelCore* StelApp::getCore (  )  [inline]

Get the core of the program.

It is the one which provide the projection, navigation and tone converter.

the StelCore instance of the program

StelLoadingBar* StelApp::getStelLoadingBar (  )  [inline]

Get the main loading bar used by modules for displaying loading informations.

the main StelLoadingBar instance of the program.

QNetworkAccessManager* StelApp::getNetworkAccessManager (  )  [inline]

Get the common instance of QNetworkAccessManager used in stellarium.

void StelApp::updateI18n (  ) 

Update translations, font for GUI and sky everywhere in the program.

void StelApp::updateSkyCulture (  ) 

Update and reload sky culture informations everywhere in the program.

QSettings* StelApp::getSettings (  )  [inline]

Return the main configuration options.

const StelStyle* StelApp::getCurrentStelStyle (  )  [inline]

Return the currently used style.

void StelApp::update ( double  deltaTime  ) 

Update all object according to the deltaTime in seconds.

void StelApp::draw (  ) 

Draw all registered StelModule in the order defined by the order lists.

the max squared distance in pixels that any object has travelled since the last update.

bool StelApp::drawPartial (  ) 

Iterate through the drawing sequence.

This allow us to split the slow drawing operation into small parts, we can then decide to pause the painting for this frame and used the cached image instead.

true if we should continue drawing (by calling the method again)

void StelApp::glWindowHasBeenResized ( float  x,
float  y,

void StelApp::reportFileDownloadFinished ( QNetworkReply *  reply  )  [slot]

Report that a download occured.

This is used for statistics purposes. Connect this slot to QNetworkAccessManager::finished() slot to obtain statistics at the end of the program.
