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.

See Also
StelObjectModule for StelModule managing collections of StelObject.
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

)
inlineprotected

convenience methods to add an action to the StelActionMgr object.

Definition at line 149 of file StelModule.hpp.

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 139 of file StelModule.hpp.

virtual void StelModule::deinit ( )
inlinevirtual

Called before the module will be delete, and before the openGL context is suppressed.

Deinitialize all openGL texture in this method.

Reimplemented in SolarSystem.

Definition at line 68 of file StelModule.hpp.

virtual void StelModule::draw ( StelCore core)
inlinevirtual

Execute all the drawing functions for this module.

Parameters
corethe core to use for the drawing

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

Definition at line 72 of file StelModule.hpp.

virtual QString StelModule::getAuthorEmail ( ) const
inlinevirtual

Get the email adress of the module author.

Definition at line 85 of file StelModule.hpp.

virtual QString StelModule::getAuthorName ( ) const
inlinevirtual

Get the name of the module author.

Definition at line 82 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

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
