Detailed Description

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::StelApp ( StelMainView * parent )

Parameters

parent the QObject parent The configFile will be searched for in the search path by the StelFileMgr, it is therefore 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

Member Function Documentation

◆ addProgressBar()

StelProgressController* StelApp::addProgressBar ( )

Returns: a controller which can be used to indicate the current status. The StelApp instance remains the owner of the controller.

◆ ensureGLContextCurrent

void StelApp::ensureGLContextCurrent ( )

slot

This is always the case during init() and draw() calls, but if OpenGL access is required elsewhere, this MUST be called before using any GL functions.

◆ getCommandlineArguments()

static QStringList StelApp::getCommandlineArguments ( )

static

You can use the CLIProcessor class to help parse it.

Returns: the arguments passed to Stellarium on the command line concatenated with the STEL_OPTS environment variable

◆ getCore()

StelCore* StelApp::getCore ( ) const

inline

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

Returns: the StelCore instance of the program

◆ getDefaultFBO

quint32 StelApp::getDefaultFBO ( ) const

inlineslot

Note that this is usually not the same as QOpenGLContext::defaultFramebufferObject(), so use this call instead of the Qt version! Valid through a StelModule::draw() call, do not use elsewhere.

◆ getDevicePixelsPerPixel()

float StelApp::getDevicePixelsPerPixel ( ) const

inline

Usually this value is 1, but for a mac with retina screen this will be value 2.

◆ getFps

float StelApp::getFps ( ) const

inlineslot

Returns: the FPS averaged on the last second

◆ getGlobalScalingRatio()

float StelApp::getGlobalScalingRatio ( ) const

inline

When this ratio is 1, all pixel sizes used in Stellarium will look OK on a regular computer screen with 96 pixel per inch (reference for tuning sizes).

◆ getInstance()

static StelApp& StelApp::getInstance ( )

inlinestatic

Returns: the StelApp singleton instance

◆ getLocaleMgr()

StelLocaleMgr& StelApp::getLocaleMgr ( ) const

inline

Returns: the font manager to use for loading fonts.

◆ getLocationMgr()

StelLocationMgr& StelApp::getLocationMgr ( ) const

inline

Returns: the Location manager to use for managing stored locations

◆ getModule()

StelModule* StelApp::getModule ( const QString & moduleID ) const

This is a shortcut for getModleMgr().getModule().

Returns: the module pointer.

◆ getModuleMgr()

StelModuleMgr& StelApp::getModuleMgr ( ) const

inline

Returns: the module manager.

◆ getSkyCultureMgr()

StelSkyCultureMgr& StelApp::getSkyCultureMgr ( ) const

inline

Returns: the sky cultures manager

◆ getStelObjectMgr()

StelObjectMgr& StelApp::getStelObjectMgr ( ) const

inline

Returns: the StelObject manager to use for querying from all stellarium objects .

◆ getTextureManager()

StelTextureMgr& StelApp::getTextureManager ( ) const

inline

Returns: the texture manager to use for loading textures.

◆ reportFileDownloadFinished

void StelApp::reportFileDownloadFinished ( QNetworkReply * reply )

slot

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

◆ setAppFont

void StelApp::setAppFont ( QFont font )

slot

To retrieve, you can use QGuiApplication::font(). emits fontChanged(font)

◆ setGui()

void StelApp::setGui ( StelGuiBase * b )

inline

The caller is responsible for destroying the GUI.

◆ setViewportEffect()

void StelApp::setViewportEffect ( const QString & effectName )

Parameters

effectName must be one of 'none', 'framebufferOnly', 'sphericMirrorDistorter'
