/**
 * @short Convenience TDECModule for creating config page handled with KAutoConfig
 *
 * This class makes it very easy to create a configuration page using KAutoConfig.
 * All you need to do is create a class that is derived from KCAutoConfigModule, create your
 * config page with TQDesigner, and add it to the module
 * This can be  done using the setMainWidget() method:
 * \code
 * typedef KGenericFactory<MyPageConfig, TQWidget> MyPageConfigFactory;
 * K_EXPORT_COMPONENT_FACTORY( kcm_mypageconfig, MyPageConfigFactory( "kcm_mypageconfig" ) )
 *
 * MyPageConfig( TQWidget * parent, const char *, const TQStringList & args )
 *     : KCAutoConfigModule( MyPageConfigFactory::instance(), parent, args )
 * {
 *       setMainWidget( new MyPageConfigBase(this) , "MyGroup" );
 * }
 * \endcode
 *
