/**
 * Convenience methods to access all standard KDE actions.
 *
 * These actions should be used instead of hardcoding menubar and
 * toolbar items.  Using these actions helps your application easily
 * conform to the <a href="https://develop.kde.org/hig/">KDE Human Interface Guidelines</a>.
 *
 * All of the documentation for QAction holds for KStandardActions
 * also.  When in doubt on how things work, check the QAction
 * documentation first.
 * Please note that calling any of these methods automatically adds the action
 * to the actionCollection() of the QObject given by the 'parent' parameter.
 *
 * <b>Simple Example:</b>\n
 *
 * In general, using standard actions should be a drop in replacement
 * for regular actions. For example, if you previously had:
 * @code
 * QAction *newAct = new QAction(QIcon::fromTheme("document-new"),
 *                               i18n("&New"),
 *                               this);
 * newAct->setShortcut(KStandardShortcut::shortcut(KStandardShortcut::New).constFirst());
 * connect(newAct, &QAction::triggered, this, &ClassFoo::fileNew);
 * @endcode
 *
 * You can replace it with:
 * @code
 * QAction *newAct = KStandardActions::openNew(this, &ClassFoo::fileNew, this);
 * @endcode
 *
 * Alternatively you can instantiate the action using the StandardAction enums
 * provided.  This author can't think of a reason why you would want to, but, hey,
 * if you do, here's how:
 *
 * \code
 * QAction *newAct = KStandardActions::create(KStandardActions::New, this, &ClassFoo::fileNew, this);
 * \endcode
 *
 * <b>Relationship with KActionCollection from KXMLGui</b>\n
 *
 * If a KActionCollection is passed as the parent then the action will be
 * automatically added to that collection:
 * \code
 * QAction *cut = KStandardActions::cut(this, &ClassFoo::editCut, actionCollection());
 * \endcode
 *
 * Each action has a unique internal name which can be queried using the
 * name method.  For example KStandardActions::name(KStandardActions::Cut)
 * would return 'edit_cut'.  This name can be used as a unique identifier
 * for the actions.  So if you wanted to add an existing standard action
 * to an action collection you can do so like this:
 * \code
 * QAction *cut = KStandardActions::cut(this, &ClassFoo::editCut, this);
 * actionCollection()->addAction(KStandardActions::name(KStandardActions::Cut), cut);
 * \endcode
 *
 * You can then get a pointer to the action using
 * \code
 * QAction *cutPtr = actionCollection()->action(KStandardActions::name(KStandardActions::Cut));
 * \endcode
