    \class Core::ActionManager
    \inheaderfile coreplugin/actionmanager/actionmanager.h
    \ingroup mainclasses
    \inmodule QtCreator

    \brief The ActionManager class is responsible for registration of menus and
    menu items and keyboard shortcuts.

    The action manager is the central bookkeeper of actions and their shortcuts
    and layout. It is a singleton containing mostly static functions. If you
    need access to the instance, for example for connecting to signals, call
    its ActionManager::instance() function.

    The action manager makes it possible to provide a central place where the
    users can specify all their keyboard shortcuts, and provides a solution for
    actions that should behave differently in different contexts (like the
    copy/replace/undo/redo actions).

    See \l{The Action Manager and Commands} for an overview of the interaction
    between Core::ActionManager, Core::Command, and Core::Context.

    Register a globally active action "My Action" by putting the following in
    your plugin's ExtensionSystem::IPlugin::initialize() function.

    \code
        QAction *myAction = new QAction(Tr::tr("My Action"), this);
        Command *cmd = ActionManager::registerAction(myAction, "myplugin.myaction", Context(C_GLOBAL));
        cmd->setDefaultKeySequence(QKeySequence(Tr::tr("Ctrl+Alt+u")));
        connect(myAction, &QAction::triggered, this, &MyPlugin::performMyAction);
    \endcode

    The \c connect is done to your own QAction instance. If you create for
    example a tool button that should represent the action, add the action from
    Command::action() to it.

    \code
        QToolButton *myButton = new QToolButton(someParentWidget);
        myButton->setDefaultAction(cmd->action());
    \endcode

    Also use the action manager to add items to registered action containers
    like the application's menu bar or menus in that menu bar. Register your
    action via the Core::ActionManager::registerAction() function, get the
    action container for a specific ID (as specified for example in the
    Core::Constants namespace) with Core::ActionManager::actionContainer(), and
    add your command to this container.

    Building on the example, adding "My Action" to the "Tools" menu would be
    done with

    \code
        ActionManager::actionContainer(Core::Constants::M_TOOLS)->addAction(cmd);
    \endcode
