Detailed Description

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
