It ensures layout is consistent + * and in general takes care of the details + * needed for making a module available in an interface. A KCModuleProxy + * can be treated as a QWidget, without worrying about the details specific + * for modules such as library loading. KCModuleProxy is not a sub class of KCModule + * but its API closely resembles KCModule's.\n + * Usually, an instance is created by passing one of the constructors a YService::Ptr, + * KCModuleInfo or simply the name of the module and then added to the layout as any + * other widget. \n + * When the user has changed the module, changed(bool) as well as changed(KCModuleProxy *) + * is emitted. KCModuleProxy does not take care of prompting for saving - if the object is deleted while + * changes is not saved the changes will be lost. changed() returns true if changes are unsaved. \n + * \n + * KCModuleProxy does not take care of authorization of KCModules. \n + * KCModuleProxy implements lazy loading, meaning the library will not be loaded or + * any other initialization done before its show() function is called. This means + * modules will only be loaded when they are actually needed as well as it is possible to + * load many KCModuleProxy without any speed penalty. + * + * KCModuleProxy should be used in all cases where modules are embedded in order to + * promote code efficiency and usability consistency. + * + * @author Frans Englich + * @author Matthias Kretz + * + */ +class KCModuleProxy : public QWidget +{ +Q_DECLARE_PRIVATE(KCModuleProxy) +Q_OBJECT +public: + /** + * Constructs a KCModuleProxy from a KCModuleInfo class. + * + * @param info The KCModuleInfo to construct the module from. + * @param parent the parent QWidget. + * @param args This is used in the implementation and is internal. + * Use the default. + */ + explicit KCModuleProxy( const KCModuleInfo& info, QWidget* parent = 0, + const QStringList& args = QStringList() ); + + /** + * Constructs a KCModuleProxy from a module's service name, which is + * equivalent to the desktop file for the kcm without the ".desktop" part. + * Otherwise equal to the one above. + * + * @param serviceName The module's service name to construct from. + * @param parent the parent QWidget. + * @param args This is used in the implementation and is internal. + * Use the default. + */ + explicit KCModuleProxy( const QString& serviceName, QWidget* parent = 0, + const QStringList& args = QStringList() ); + + /** + * Constructs a KCModuleProxy from YService.
