 * This class is used automatically by KMainWindow and KDialog to attach a
 * What's This templates to all new widgets. If you don't use either of those
 * classes and want this functionality, call KWhatsThisManager::init () before
 * creating any widgets.
 *
 * It works by watching for child creation events and if the new objects are
 * widgets, it attachs the whatsthis template to them (unless there already is
 * What's This defined). This template will be overridden by any custom What's
 * This info.
