Detailed Description

This is the common base class for all the main components of stellarium.

Standard StelModules are the one displaying the stars, the constellations, the planets etc.. Every new module derived class should implement the methods defined in StelModule.hpp. Once a module is registered into the StelModuleMgr, it is automatically managed by the program. It can be called using the GETSTELMODULE macro, passing as argument its name, which is also the QObject name Because StelModules are very generic components, it is also possible to load them dynamically, thus enabling creation of external plug-ins for stellarium.

Plugins for documentation on how to develop external plugins.

There are several signals that StelApp emits that subclasses may be interested in: laguageChanged() Update i18n strings from english names according to current global sky and application language. This method also reload the proper fonts depending on the language. The translation shall be done using the StelTranslator provided by the StelApp singleton instance. skyCultureChanged(const QString&) Update sky culture, i.e. load data if necessary and translate them to current sky language if needed. colorSchemeChanged(const QString&) Load the given color style

Member Function Documentation

virtual bool StelModule::configureGui ( bool  show = true)
inlinevirtual

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.

Definition at line 141 of file StelModule.hpp.

virtual void StelModule::deinit ( )
inlinevirtual

Called before the module will be deleted, and before the renderer is destroyed.

Deinitialize all textures in this method.

Definition at line 65 of file StelModule.hpp.

virtual void StelModule::draw ( StelCore core,
class StelRenderer renderer 
)
inlinevirtual

Execute all the drawing functions for this module.

Parameters
corethe core to use for the drawing
rendererRenderer to draw with.

Reimplemented in GridLinesMgr, ScreenImageMgr, ConstellationMgr, StarMgr, LandscapeMgr, SolarSystem, NebulaMgr, LabelMgr, StelMovementMgr, MeteorMgr, MilkyWay, StelSkyLayerMgr, and StelObjectMgr.

Definition at line 70 of file StelModule.hpp.

virtual bool StelModule::drawPartial ( StelCore core,
class StelRenderer renderer 
)
virtual

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.

Returns
true if we should continue drawing (by calling the method again)
virtual QString StelModule::getAuthorEmail ( ) const
inlinevirtual

Get the email adress of the module author.

Definition at line 93 of file StelModule.hpp.

virtual QString StelModule::getAuthorName ( ) const
inlinevirtual

Get the name of the module author.

Definition at line 90 of file StelModule.hpp.

virtual double StelModule::getCallOrder ( StelModuleActionName  actionName) const
inlinevirtual

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 in GridLinesMgr, ScreenImageMgr, ConstellationMgr, StarMgr, LandscapeMgr, SolarSystem, NebulaMgr, LabelMgr, MeteorMgr, MilkyWay, and StelSkyLayerMgr.

Definition at line 135 of file StelModule.hpp.

virtual QString StelModule::getModuleVersion ( ) const
virtual

Get the version of the module, default is stellarium main version.

virtual void StelModule::handleKeys ( class QKeyEvent *  e)
inlinevirtual

Handle key events.

Please note that most of the interactions will be done through the GUI module.

Parameters
ethe Key event
Returns
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

Definition at line 110 of file StelModule.hpp.

virtual void StelModule::handleMouseClicks ( class QMouseEvent *  )
inlinevirtual

Handle mouse clicks.

Please note that most of the interactions will be done through the GUI module.

Returns
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

Definition at line 97 of file StelModule.hpp.

virtual bool StelModule::handleMouseMoves ( int  x,
int  y,
Qt::MouseButtons  b 
)
inlinevirtual

Handle mouse moves.

Please note that most of the interactions will be done through the GUI module.

Returns
true if the event was intercepted

Reimplemented in StelMovementMgr.

Definition at line 105 of file StelModule.hpp.

virtual void StelModule::handleMouseWheel ( class QWheelEvent *  )
inlinevirtual

Handle mouse wheel.

Please note that most of the interactions will be done through the GUI module.

Returns
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

Definition at line 101 of file StelModule.hpp.

virtual void StelModule::init ( )
pure virtual

Initialize itself.

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

Implemented in GridLinesMgr, ScreenImageMgr, ConstellationMgr, StarMgr, LandscapeMgr, NebulaMgr, SolarSystem, LabelMgr, StelMovementMgr, MeteorMgr, StelSkyLayerMgr, MilkyWay, StelObjectMgr, and StelGeodesicGridDrawer.

virtual void StelModule::update ( double  deltaTime)
pure virtual

Update the module with respect to the time.

Parameters
deltaTimethe time increment in second since last call.

Implemented in GridLinesMgr, ScreenImageMgr, ConstellationMgr, StarMgr, LandscapeMgr, SolarSystem, NebulaMgr, LabelMgr, MeteorMgr, MilkyWay, StelMovementMgr, StelSkyLayerMgr, StelObjectMgr, and StelGeodesicGridDrawer.
